*todo.txt* For Vim version 7.1. Last change: 2007 Oct 02 VIM REFERENCE MANUAL by Bram Moolenaar TODO list for Vim *todo* This is a veeeery long list of known bugs, current work and desired improvements. To make it a little bit accessible, the items are grouped by subject. In the first column of the line a classification is used to be able to look for "the next thing to do": Priority classification: 9 next point release 8 next release 7 as soon as possible 6 soon 5 should be included 4 nice to have 3 consider including 2 maybe not 1 probably not - unclassified *votes-for-changes* See |develop.txt| for development plans. You can vote for which items should be worked on, but only if you sponsor Vim development. See |sponsor|. *known-bugs* -------------------- Known bugs and current work ----------------------- Win32: When editing a file c:\tmp\foo and c:\tmp\\foo we have two buffers for the same file. (Suresh Govindachar) Have a look at the Ex commands that Bjorn Winckler added in MacVim. Insert mode completion: CTRL-N and CTRL-P work differently and they both don't work as expected. (Bernhard Walle, 2007 Feb 27) Insert mode completion: ":set complete+=] completeopt+=longest showfulltag" and complete something from a tags file: get nothing. "showfulltag" causes the list of matches to be messed up. (Andri Moell, 2007 Aug 13) glob() doesn't work correctly with single quotes and 'shell' set to /bin/sh. (Adri Verhoef, Charles Campbell 2007 Mar 26) Win32: Using the example at 'balloonexpr' the balloon disappears after four seconds and then comes back again. Also appears to move the mouse pointer. (Yongwei Wu). Error in session file: mix of tab pages and argument list. (Eggner, 2007 Aug 22) netrw: edit dir, no-name buffer in other window, click in other window: Error detected while processing function 44_NetBrowseChgDir: line 5: (NetBrowseChgDir) b:netrw_curdir doesn't exist! Replace ccomplete.vim by cppcomplete.vim from www.vim.org? script 1520 by Vissale Neang. (Martin Stubenschrott) ctags -R --c++-kinds=+p --fields=+iaS --extra=+q . Problem listing map for Û when 'encoding' is utf-8. (Tony Mechelynck, 2007 Sep 27) Probably because the second byte is 0x9b. Cheng Fang made javacomplete. (2007 Aug 11) Find a way to include the regexp code: http://vim-soc-regexp.googlecode.com/svn/ (sbboat one) Merge the two branches. Avoid duplicating code from regexp.c. More testing. Problem with searchpair() using 'c' flag and skip function. (A.Politz, 2007 Aug 25) Perhaps don't use 'c' flag when continuing after a skip? Also a problem with 'r' flag when when 'wrapscan' is set. Should imply 'W' flag? (A.Politz, 2007 Sep 4) Suggested patch by Antony Scriven (2007 Sep 5). But hange this: options &= ~SEARCH_START; Making the German sharp s uppercase doesn't work properly: one character less is uppercased in "gUe". Also: latin2 has the same character but it isn't uppercased there. Mac: After a ":vsplit" the left scrollbar doesn't appear until 'columns' is changed or the window is resized. Mac: Patch for Mac GUI tabline. (Nicolas Weber, 2006 Jul 18, Update 2007 Feb) New update v6 ~/tmp/guitab.v6.diff (Kyle Wheeler) Mac: Patch for the dialog hotkeys. (Dan Sandler, 2007 Sep 11) Mac: patch for ATSUI: http://wiki.macvim.org/wiki/VimPatches/ATSUI Problem with 'ts' set to 9 and 'showbreak' to ">>>". (Matthew Winn, 2007 Oct 1) Using Aap to build Vim: add remarks about how to set personal preferences. Example on http://www.calmar.ws/tmp/aap.html Syntax highlighting wrong for transparent region. (Doug Kearns, 2007 Feb 26) Bug in using a transparent syntax region. (Hanlen in vim-dev maillist, 2007 Jul 31) C syntax: {} inside () causes following {} to be highlighted as error. (Michalis Giannakidis, 2006 Jun 1) Gnome improvements: Edward Catmur, 2007 Jan 7 Also use Save/Discard for other GUIs New PHP syntax file, use it? (Peter Hodge) 'foldcolumn' in modeline applied to wrong window when using a session. (Teemu Likonen, March 19) More AmigaOS4 patches. (Peter Bengtsson, Nov 9) Add v:searchforward variable. Patch by Yakov Lerner, 2006 Nov 18. With Visual selection, "r" and then CTRL-C Visual mode is stopped but the highlighting is not removed. Screen redrawing when continuously updating the buffer and resizing the terminal. (Yakov Lerner, 2006 Sept 7) Add option settings to help ftplugin. (David Eggum, 2006 Dec 18) Autoconf problem: when checking for iconv library we may add -L/usr/local/lib, but when compiling further tests -liconv is added without the -L argument, that may fail (e.g., sizeof(int)). (Blaine, 2007 Aug 21) Use new dutch wordlist for spelling? http://www.opentaal.org/ See remarks from Adri, 2007 Feb 9. When opening quickfix window, disable spell checking? Popup menu redraw: Instead of first redrawing the text and then drawing the popup menu over it, first draw the new popup menu, remember its position and size and then redraw the text, skipping the characters under the popup menu. This should avoid flicker. Other solution by A.Politz, 2007 Aug 22. With a nasty spell file one can read past the end of the file and use lots of memory. Patch by James Vega, 2007 June 20. Windows 98: pasting from the clipboard with text from another application has a trailing NUL. (Joachim Hofmann) Perhaps the length specified for CF_TEXT isn't right? Completion: Scanning for tags doesn't check for typed key now and then? Hangs for about 5 seconds. Appears to be caused by finding include files with "foo/**" in 'path'. (Kalisiak, 2006 July 15) ":e foo\ ~\ foo" doesn't work when 'shell' is "sh". Works OK when 'shell' is "tcsh". Hint: use "for i in ; do echo $i; done". Patch by Dasn, 2007 Sep 22. Also: '0 mark doesn't work for this file. Patch by Dasn, 2007 Sep 24. Completion: When 'completeopt' has "longest" and there is one match the message is "back at original" and typing a char doesn't leave completion mode. (Igor Prischepoff, 2006 Oct 5) Completion: When using CTRL-X O and there is only "struct." before the cursor, typing one char to reduce the matches, then BS completion stops. Should keep completion if still no less than what we started with. Completion: don't stop completion when typing a space when completing full lines? Also when completing file names? Only stop completion when there are no matches? After using BS completion only stops when typing a space. Many people want to stop at non-word characters, e.g., '('. Add an option for this? Or check vim_iswordc() before calling ins_compl_addleader()? Color for cUserLabel should differ from case label, so that a mistake in a switch list is noticed: switch (i) { case 1: foobar: } Look at http://www.gtk-server.org/ . It has a Vim script implementation. Netbeans problem. Use "nc -l 127.0.0.1 55555" for the server, then run gvim with "gvim -nb:localhost:55555:foo". From nc do: '1:editFile!0 "foo"'. Then go to Insert mode and add a few lines. Then backspacing every other time moves the cursor instead of deleting. (Chris Kaiser, 2007 Sep 25) Redraw problem when appending digraph causes line to wrap. (James Vega, 2007 Sep 18) Changes for Win32 makefile. (Mike Williams, 2007 Jan 22, Alexei Alexandrov, 2007 Feb 8) Patch for Win32 clipboard under Cygwin. (Frodak Baksik, Feb 15) Sutcliffe says it works well. Update 2007 May 22 for Vim 7.1 Win32: Patch for convert_filterW(). (Taro Muraoka, 2007 Mar 2) Win32: Patch for cscope external command. (Mike Williams, 2007 Aug 7) Win32: XPM support only works with path without spaces. Patch by Mathias Michaelis, 2006 Jun 9. Another patch for more path names, 2006 May 31. New version: http://members.tcnet.ch/michaelis/vim/patches.zip (also for other patches by Mathias, see mail Feb 22) Win32: compiling with normal features and OLE fails. Patch by Mathias Michaelis, 2006 Jun 4. Win32: echo doesn't work for gvim.exe.mnf. Use inline file. Patch by Mathias Michaelis. http://groups.yahoo.com/group/vimdev/message/43765 Patch that includes this and does more by George Reilly, 2007 Feb 12 Win16: include patches to make Win16 version work. (Vince Negri, 2006 May 22) Win32: after "[I" showing matches, scroll wheel messes up screen. (Tsakiridis, 2007 Feb 18) Patch by Alex Dobrynin, 2007 Jun 3. Also fixes other scroll wheel problems. Win32: using CTRL-S in Insert mode doesn't remove the "+" from the tab pages label. (Tsakiridis, 2007 Feb 18) Win64: diff.exe crashes on Win64. (Julianne Bailey, 2006 Dec 12) Build another diff.exe somehow? Win64: Seek error in swap file for a very big file (3 Gbyte). Check storing pointer in long and seek offset in 64 bit var. Menu item that does "xxd -r" doesn't work when 'fileencoding' is utf-16. Check for this and use iconv? (Edward L. Fox, 2007 Sep 12) Does the conversion in the other direction work when 'filenecodings' is set properly? Can't use an expression for the :catch argument. Support `=expression`. Cursor displayed in the wrong position when using 'numberwidth'. (James Vega, 2007 Jun 21) Problem finding swap file for recovery. (Gautam Iyer, 2006 May 16) UTF-8: mapping a multi-byte key where the second byte is 0x80 doesn't appear to work. (Tony Mechelynck, 2007 March 2) The str2special() function doesn't handle multi-byte characters properly. Patch from Vladimir Vichniakov, 2007 Apr 24. find_special_key() also has this problem. In debug mode, using CTRL-R = to evaluate a function causes stepping through the function. (Hari Krishna Dara, 2006 Jun 28) C++ indenting wrong with "=". (James Kanze, 2007 Jan 26) ":lockvar" should use copyID to avoid endless loop. Patch to use xterm mouse codes for screen. (Micah Cowan, 2007 May 8) Gvim: dialog for closing Vim should check if Vim is busy writing a file. Then use a different dialog: "busy saving, really quit? yes / no". Check other interfaces for changing curbuf in a wrong way. Patch like for if_ruby.c. Spell checking in popup menu: If the only problem is the case of the first character, don't offer "ignore" and "add to word list". ":helpgrep" should use the directory from 'helpfile'. The need_fileinfo flag is messy. Instead make the message right away and put it in keep_msg? Editing a file remotely that matches 'wildignore' results in a "no match" error. Should only happen when there are wildards, not when giving the file name literally, and esp. if there is only one name. Test 61 fails sometimes. This is a timing problem: "sleep 2" sometimes takes longer than 2 seconds. Changing 'guifont' in the console causes an uneccessary redraw. VMS: while editing a file found in complex, Vim will save file into the first directory of the path and not to the original location of the file. (Zoltan Arpadffy) input() completion should not insert a backslash to escape a space in a file name? getpos()/setpos() don't include curswant. getpos() could return a fifth element. setpos() could accept an optional fifth element. Ruby completion is insecure. Can this be fixed? When 'backupskip' is set from $TEMP special characters need to be escaped. (patch by Grembowietz, 2007 Feb 26, not quite right) Another problem is that file_pat_to_reg_pat() doesn't recognize "\\", so "\\(" will be seen as a path separator plus "\(". ":python os.chdir('/tmp')" makes short buffer names invalid. (Xavier de Gaye) Check directory and call shorten_fnames()? aucmd_prepbuf() should also use a window in another tab page. Substituting an area with a line break with almost the same area does change the Visual area. Can this be fixed? (James Vega, 2006 Sept 15) Windows installer could add a "open in new tab of existing Vim" menu entry. GUI: When combining fg en bg make sure they are not equal. Use different pt_br dictionary for spell checking. (Jackson A. Aquino, 2006 Jun 5) Mac: Using gvim: netrw window disappears. (Nick Lo, 2006 Jun 21) Add an option to specify the character to use when a double-width character is moved to the next line. Default '>', set to a space to blank it out. Check that char is single width when it's set (compare with 'listchars'). The generated vim.bat can avoid the loop for NT. (Carl Zmola, 2006 Sep 3) Session file creation: 'autochdir' causes trouble. Keep it off until after loading all files. Add autocommand for when a tabpage is being closed. Also for when a tab page has been created. Using ":make" blocks Vim. Allow running one make in the background (if the shell supports it), catch errors in a file and update the error list on the fly. A bit like "!make > file&" and repeating ":cf file". ":bgmake", background make. ":bgcancel" interrupts it. A.Politz may work on this. The spellfile plugin checks for a writable "spell" directory. A user may have a writable runtime directory without a "spell" directory, it could be created then. These two abbreviations don't give the same result: let asdfasdf = "xyz\" cabbr XXX =asdfasdf cabbr YYY xyz Michael Dietrich: maximized gvim sometimes displays output of external command partly. (2006 Dec 7) In FileChangedShell command it's no longer allowed to switch to another buffer. But the changed buffer may differ from the current buffer, how to reload it then? New syntax files for fstab and resolv from Radu Dineiu, David Necas did previous version. For Aap: include a config.arg.example file with hints how to use config.arg. Command line completion when 'cmdheight' is maximum and 'completeopt' has "menu, only one buffer line displayed, causes display errors. Linux distributions: - Suggest compiling xterm with --enable-tcap-query, so that nr of colors is known to Vim. 88 colors instead of 16 works better. See ":help xfree-xterm". - Suggest including bare "vi" and "vim" with X11, syntax, etc. Hang in syntax syncing for automake? (James Vega, 2007 Jun 18) Completion menu: For a wrapping line, completing a long file name, only the start of the path is shown in the menu. Should move the menu to the right to show more text of the completions. Shorten the items that don't fit in the middle? When running inside screen it's possible to kill the X server and restart it (using pty's the program can keep on running). Vim dies because it looses the connection to the X server. Can Vim simply quit using the X server instead of dying? Also relevant when running in a console. Accessing file#var in a function should not need the g: prepended. When ":cn" moves to an error in the same line the message isn't shortened. Only skip shortening for ":cc"? Write "making vim work better" for the docs (mostly pointers): *nice* - sourcing $VIMRUNTIME/vimrc_example.vim - setting 'mouse' to "a" - getting colors in xterm - compiling Vim with X11, GUI, etc. Problem with ":call" and dictionary function. Hari Krishna Dara, Charles Campbell 2006 Jul 06. Syntax HL error caused by "containedin". (Peter Hodge, 2006 Oct 6) ":help s/~" jumps to *s/\~*, while ":help s/\~" doesn't find anything. (Tim Chase) Nieuwe site en maillist voor Vim scripts: http://vim-scripts.googlecode.com http://groups.google.com/group/vim_scripts Ergens op www.vim.org vermelden? A custom completion function in a ":command" cannot be a Funcref. (Andy Wokula, 2007 Aug 25) GTK: When maximizing Vim the result is slightly smaller, the filler border is not there, and the "maximize" button is still there. Clicking it again does give a maximized window. (Darren Hiebert) Problem is that gui_mch_set_text_area_pos() is invoked to change the text area size, which causes the toplevel window to resize. When doing this while the size is already right the filler remains there. Detect using the maximize button (GdkWindowState bit GDK_WINDOW_STATE_MAXIMIZED) and set it again? GTK GUI: When the completion popup menu is used scrolling another window by the scrollbar is OK, but using the scroll wheel it behaves line . Another resizing problem when setting 'columns' and 'lines' to a very large number. (Tony Mechelynck, 2007 Feb 6) Problem with using :redir in user command completion function? (Hari Krishna Dara, 2006 June 21) After starting Vim, using '0 to jump somewhere in a file, ":sp" doesn't center the cursor line. It works OK after some other commands. Win32: Is it possible to have both postscript and Win32 printing? Does multi-byte printing with ":hardcopy" work? Add remark in documentation about this. There should be something about spell checking in the user manual. Check: Running Vim in a console and still having connect to the X server for copy/paste: is stopping the X server handled gracefully? Should catch the X error and stop using the connection to the server. Problem with 'cdpath' on MS-Windows when a directory is equal to $HOME. (2006 Jul 26, Gary Johnson) In the Netbeans interface add a "vimeval" function, so that the other side can check the result of has("patch13"). Add command modifier that skips wildcard expansion, so that you don't need to put backslashes before special chars, only for white space. Win32: When the GUI tab pages line is displayed Vim jumps from the secondary to the primary monitor. (Afton Lewis, 2007 Mar 9) Old resizing problem? The magic clipboard format "VimClipboard2" appears in several places. Should be only one. It's difficult to debug numbered functions (function in a Dictionary). Print the function name before resolving it to a number? let d = {} fun! d.foo() echo "here" endfun call d.foo(9) Add a mark for the other end of the Visual area (VIsual pos). '< and '> are only set after Visual moded is ended. Win32: When running ":make" and 'encoding' differs from the system locale, the output should be converted. Esp. when 'encoding' is "utf-8". (Yongwei Wu) Should we use 'termencoding' for this? Small problem displaying diff filler line when opening windows with a script. (David Luyer, 2007 Mar 1 ~/Mail/oldmail/mool/in.15872 ) Is it allowed that 'backupext' is empty? Problems when backup is in same dir as original file? If it's OK don't compare with 'patchmode'. (Thierry Closen) Patch for supporting count before CR in quickfix window. (AOYAMA Shotaro, 2007 Jan 1) Patch for adding ":lscscope". (Navdeep Parhar, 2007 Apr 26; update Apr 28) ":mkview" isn't called with the right buffer argument. Happens when using tabs and the autocommand "autocmd BufWinLeave * mkview". (James Vega, 2007 Jun 18) Patch for improving regexp speed by not freeing memory. (Alexei Alexandrov, 2007 Feb 6) xterm should be able to pass focus changes to Vim, so that Vim can check for buffers that changed. Perhaps in misc.c, function selectwindow(). Xterm 224 supports it! The matchparen plugin finds matching parens in a much better way than "%". Add an option to make "%" work like the plugin. OR: suggest using the matchit plugin? Compare speed. When completing from another file that uses a different encoding completion text has the wrong encoding. E.g., when 'encoding' is utf-8 and file is latin1. Example from Gombault Damien, 2007 Mar 24. Is it possible to use "foo#var" instead of "g:foo#var" inside a function? TermResponse autocommand isn't always triggered when using vimdiff. (Aron Griffis, 2007 Sep 19) Patch for configure.in to support cross-compiling: Marc Haisenko, 2007 Sep 24. Vim 7.2: - Change all use of mch_memmove(p, p + x, STRLEN(p + x) + 1) to a macro: VIM_STRCPY(p, p + x) - Rename doc/ada.txt to doc/ft_ada.txt? - Search offset doesn't work for multibyte character. Patch from Yukihiro Nakadaira, 2006 Jul 18. Changes the offset from counting bytes to counting characters. - Rename the tutor files from tutor.gr.* to tutor.el.*. Greece vs Greek. Make all tutor files available in utf-8. - Remove ! for ":cgetfile" and ":lgetfile". (patch from Yegappan Lakshmanan, 2007 Mar 9) - Add blowfish encryption. Openssl has an implementation. Also by Paul Kocher (LGPL), close to original. Mohsin also has some ideas. Take four bytes and turn them into unsigned to avoid byte-order problems. Need to buffer up to 7 bytes to align on 8 byte boundaries. - Rename doc/sql.vim doc/ft_sql.vim. - Change "command-line" to "[Command Line]" for the command line buffer name in ex_window(). - Move including fcntl.h to vim.h, before O_NOFOLLOW, and remove it from all .c files. - ":{range}source": source the lines from the file. You can already yank lines and use :@" to execute them. Most of do_source() would not be used, need a new function. It's easy when not doing breakpoints or profiling. Patches: - Add 'cscopeignorecase' option. (Liang Wenzhi, 2006 Sept 3) - Argument for feedkeys() to prepend to typeahead (Yakov Lerner, 2006 Oct 21) - Load intl.dll too, not only libintl.dll. (Mike Williams, 2006 May 9, docs patch May 10) - Extra argument to strtrans() to translate special keys to their name (Eric Arnold, 2006 May 22) - 'threglookexp' option: only match with first word in thesaurus file. (Jakson A. Aquino, 2006 Jun 14) - Mac: indicate whether a buffer was modified. (Nicolas Weber, 2006 Jun 30) - Allow negative 'nrwidth' for left aligning. (Nathan Laredo, 2006 Aug 16) - ml_append_string(): efficiently append to an existing line. (Brad Beveridge, 2006 Aug 26) Use in some situations, e.g., when pasting a character at a time? - gettabvar() and settabvar() functions. (Yegappan Lakshmanan, 2007 Sep 13) - recognize hex numbers better. (Mark Manning, 2006 Sep 13) Awaiting updated patches: 9 Mac unicode patch (Da Woon Jung, Eckehard Berns): 8 Add patch from Muraoka Taro (Mar 16) to support input method on Mac? New patch 2004 Jun 16 - selecting proportional font breaks display - UTF-8 text causes display problems. Font replacement causes this. - Command-key mappings do not work. (Alan Schmitt) - With 'nopaste' pasting is wrong, with 'paste' Command-V doesn't work. (Alan Schmitt) - remove 'macatsui' option when this has been fixed. - when 'macatsui' is off should we always convert to "macroman" and ignore 'termencoding'? 9 HTML indenting can be slow. Caused by using searchpair(). Can search() be used instead? 8 Win32: Add minidump generation. (George Reilly, 2006 Apr 24) 8 Add ":n" to fnamemodify(): normalize path, remove "../" when possible. Aric Blumer has a patch for this. He will update the patch for 6.3. 7 Completion of network shares, patch by Yasuhiro Matsumoto. Update 2004 Sep 6. How does this work? Missing comments. - Patch for 'breakindent' option: repeat indent for wrapped line. (Vaclav Smilauer, 2004 Sep 13, fix Oct 31, update 2007 May 30) 8 Add a few more command names to the menus. Patch from Jiri Brezina (28 feb 2002). Will mess the translations... 7 ATTENTION dialog choices are more logical when "Delete it' appears before "Quit". Patch by Robert Webb, 2004 May 3. - Include flipcase patch: ~/vim/patches/wall.flipcase2 ? Make it work for multi-byte characters. - Win32: add options to print dialog. Patch from Vipin Aravind. - Patch to add highlighting for whitespace. (Tom Schumm, 2003 Jul 5) use the patch that keeps using HLF_8 if HLF_WS has not been given values. Add section in help files for these highlight groups? 8 "fg" and "bg" don't work in an xterm. Get default colors from xterm with an ESC sequence. xterm can send colors for many things. E.g. for the cursor: ]12;? Can use this to get the background color and restore the colors on exit. 7 Add "DefaultFG" and "DefaultBG" for the colors of the menu. (Marcin Dalecki has a patch for Motif and Carbon) - Add possibility to highlight specific columns (for Fortran). Or put a line in between columns (e.g., for 'textwidth'). Patch to add 'hlcolumn' from Vit Stradal, 2004 May 20. 8 Add functions: gettext() Translate a message. (Patch from Yasuhiro Matsumoto) Update 2004 Sep 10 Another patch from Edward L. Fox (2005 Nov 24) Search in 'runtimepath'? More docs needed about how to use this. How to get the messages into the .po files? confirm() add "flags" argument, with 'v' for vertical layout and 'c' for console dialog. (Haegg) Flemming Madsen has a patch for the 'c' flag (2003 May 13) raisewin() raise gvim window (see HierAssist patch for Tcl implementation ~/vim/HierAssist/ ) taglist() add argument to specify maximum number of matches. useful for interactive things or completion. col('^') column of first non-white character. Can use "len(substitute(getline('.'), '\S.*', '', '')) + 1", but that's ugly. 7 Make globpath() also work with upwards search. (Brian Medley) 7 Add patch from Benoit Cerrina to integrate Vim and Perl functions better. Now also works for Ruby (2001 Nov 10) - Patch from Herculano de Lima Einloft Neto for better formatting of the quickfix window (2004 dec 2) 7 When 'rightleft' is set, the search pattern should be displayed right to left as well? See patch of Dec 26. (Nadim Shaikli) 8 Option to lock all used memory so that it doesn't get swapped to disk (uncrypted). Patch by Jason Holt, 2003 May 23. Uses mlock. 7 Support a stronger encryption. Jason Holt implemented AES (May 6 2003). 7 Add ! register, for shell commands. (patch from Grenie) 8 In the gzip plugin, also recognize *.gz.orig, *.gz.bak, etc. Like it's done for filetype detection. Patch from Walter Briscoe, 2003 Jul 1. 7 Add a "-@ filelist" argument: read file names from a file. (David Kotchan has a patch for it) 8 Include a connection to an external program through a pipe? See patches from Felbinger for a mathematica interface. Or use emacs server kind of thing? 7 Add ":justify" command. Patch from Vit Stradal 2002 Nov 25. - findmatch() should be adjusted for Lisp. See remark at get_lisp_indent(). Esp. \( and \) should be skipped. (Dorai Sitaram, incomplete patch Mar 18) - For GUI Find/Replace dialog support using a regexp. Patch for Motif and GTK by degreneir (nov 10 and nov 18). - Patch for "paranoid mode" by Kevin Collins, March 7. Needs much more work. Vi incompatibility: - Try new POSIX tests, made after my comments. (Geoff Clare, 2005 April 7) Version 1.5 is in ~/src/posix/1.5. (Lynne Canal) 8 With undo/redo only marks in the changed lines should be changed. Other marks should be kept. Vi keeps each mark at the same text, even when it is deleted or restored. (Webb) Also: A mark is lost after: make change, undo, redo and undo. Example: "{d''" then "u" then "d''": deletes an extra line, because the '' position is one line down. (Veselinovic) 8 When stdin is not a tty, and Vim reads commands from it, an error should make Vim exit. 7 Unix Vim (not gvim): Typing CTRL-C in Ex mode should finish the line (currently you can continue typing, but it's truncated later anyway). Requires a way to make CTRL-C interrupt select() when in cooked input. 8 When loading a file in the .exrc, Vi loads the argument anyway. Vim skips loading the argument if there is a file already. When no file argument given, Vi starts with an empty buffer, Vim keeps the loaded file. (Bearded) 6 In Insert mode, when using or , don't wipe out the text, but only move back the cursor. Behaves like '$' in 'cpoptions'. Use a flag in 'cpoptions' to switch this on/off. 8 When editing a file which is a symbolic link, and then opening another symbolic link on the same file, Vim uses the name of the first one. Adjust the file name in the buffer to the last one used? Use several file names in one buffer??? Also: When first editing file "test", which is symlink to "test2", and then editing "test2", you end up editing buffer "test" again. It's not logical that the name that was first used sticks with the buffer. 7 The ":undo" command works differently in Ex mode. Edit a file, make some changes, "Q", "undo" and _all_ changes are undone, like the ":visual" command was one command. On the other hand, an ":undo" command in an Ex script only undoes the last change (e.g., use two :append commands, then :undo). 7 The ":map" command output overwrites the command. Perhaps it should keep the ":map" when it's used without arguments? 7 CTRL-L is not the end of a section? It is for Posix! Make it an option. 7 Implement 'prompt' option. Init to off when stdin is not a tty. 7 CTRL-T in Insert mode inserts 'shiftwidth' of spaces at the cursor. Add a flag in 'cpoptions' for this. 7 Add a way to send an email for a crashed edit session. Create a file when making changes (containing name of the swap file), delete it when writing the file. Supply a program that can check for crashed sessions (either all, for a system startup, or for one user, for in a .login file). 7 Vi doesn't do autoindenting when input is not from a tty (in Ex mode). 7 "z3" should still use the whole window, but only redisplay 3 lines. 7 ":tag xx" should move the cursor to the first non-blank. Or should it go to the match with the tag? Option? 7 Implement 'autoprint'/'ap' option. 7 Add flag in 'cpoptions' that makes after a count work like (Sayre). 7 Add flag in 'cpoptions' that makes operator (yank, filter) not move the cursor, at least when cancelled. (default Vi compatible). 7 This Vi-trick doesn't work: "Q" to go to Ex mode, then "g/pattern/visual". In Vi you can edit in visual mode, and when doing "Q" you jump to the next match. Nvi can do it too. 7 Support '\' for line continuation in Ex mode for these commands: (Luebking) g/./a\ g/pattern1/ s/pattern2/rep1\\ line 1\ line 2\\ line 2\ line 3\\ . line4/ 6 ":e /tmp/$tty" doesn't work. ":e $uid" does. Is $tty not set because of the way the shell is started? 6 Vi compatibility (optional): make "ia10." do the same strange thing. (only repeat insert for the first line). GTK+ 1 (OK in GTK 2): 8 When using "gvim -geom 40x30" or setting 'columns' in .gvimrc or with a GUIEnter autocommand, the width is still set to fit the toolbar. Also happens when changing the font. How to avoid that the toolbar specifies the minimal window width? 8 When using a theme with different scrollbars (gtkstep), the scrollbars can be too narrow. (Drazen Kacar) 8 Font "7x14" has a bold version "7x14bold". Try to find the bold font by appending "bold" when there are not 14 dashes. GTK+ GUI known bugs: 9 Crash with X command server over ssh. (Ciaran McCreesh, 2006 Feb 6) 8 GTK 2: Combining UTF-8 characters not displayed properly in menus (Mikolaj Machowski) They are displayed as separate characters. Problem in creating a label? 8 GTK 2: Combining UTF-8 characters are sometimes not drawn properly. Depends on the font size, "monospace 13" has the problem. Vim seems to do everything right, must be a GTK bug. Is there a way to work around it? 9 Can't paste a Visual selection from GTK-gvim to vim in xterm or Motif gvim when it is longer than 4000 characters. Works OK from gvim to gvim and vim to vim. Pasting through xterm (using the shift key) also works. It starts working after GTK gvim loses the selection and gains it again. - Gnome2: When moving the toolbar out of the dock, so that it becomes floating, it can no longer be moved. Therefore making it float has been blocked for now. Win32 GUI known bugs: - Win32: tearoff menu window should have a scrollbar when it's taller than the screen. 8 non-ASCII font names don't work. Need to convert from 'encoding' and use the wide functions. 8 On Windows 98 the unicows library is needed to support functions with UCS2 file names. Can we load unicows.dll dynamically? 8 When the primary monitor is below or right of the secondary monitor and Vim is on the secondary monitor it will often move to the primary monitor. Window position coordinates can be negative. (James Harvey) 8 The -P argument doesn't work very well with many MDI applications. The last argument of CreateWindowEx() should be used, see MSDN docs. Tutorial: http://win32assembly.online.fr/tut32.html 8 In eval.c, io.h is included when MSWIN32 is defined. Shouldn't this be WIN32? Or can including io.h be moved to vim.h? (Dan Sharp) 7 Windows XP: When using "ClearType" for text smoothing, a column of yellow pixels remains when typing spaces in front of a "D" ('guifont' set to "lucida_console:h8"). 6 Win32 GUI: With "-u NONE -U NONE" and doing "CTRL-W v" "CTRL-W o", the ":" of ":only" is highlighted like the cursor. (Lipelis) 8 When 'encoding' is "utf-8", should use 'guifont' for both normal and wide characters to make Asian languages work. Win32 fonts contain both type of characters. 7 When font smoothing is enabled, redrawing can become very slow. The reason appears to be drawing with a transparent background. Would it be possible to use an opaque background in most places? 8 Use another default for 'termencoding': the active codepage. Means that when 'encoding' is changed typing characters still works properly. Alternative: use the Unicode functions to obtain typed characters. 8 Win32: Multi-byte characters are not displayed, even though the same font in Notepad can display them. (Srinath Avadhanula) Try with the UTF-8-demo.txt page with Andale Mono. 7 The cursor color indicating IME mode doesn't work properly. (Shizhu Pan, 2004 May 9) 8 Win32: When clicking on the gvim title bar, which gives it focus, produces a file-changed dialog, after clicking on a button in that dialog the gvim window follows the mouse. The button-up event is lost. Only with MS-Windows 98? Try this: ":set sw ts", get enter-prompt, then change the file in a console, go back to Vim and click "reload" in the dialog for the changed file: Window moves with the cursor! Put focus event in input buffer and let generic Vim code handle it? 8 Win32: When mouse is hidden and in the toolbar, moving it won't make it appear. (Sami Salonen) 8 Win32 GUI: With maximized window, ":set go-=r" doesn't use the space that comes available. (Poucet) It works OK on Win 98 but doesn't work on Win NT 4.0. Leaves a grey area where the scrollbar was. ":set go+=r" also doesn't work properly. 8 When Vim is minimized and when maximizing it a file-changed dialog pops up, Vim isn't maximized. It should be done before the dialog, so that it appears in the right position. (Webb) 9 When selecting at the more-prompt or hit-enter-prompt, the right mouse button doesn't give popup menu. At the hit-enter prompt CTRL-Y doesn't work to copy the modeless selection. On the command line, don't get a popup menu for the right mouse button. Let the middle button paste selected text (not the clipboard but the non-Visual selection)? Otherwise CTRL-Y has to be used to copy the text. 8 When 'grepprg' doesn't execute, the error only flashes by, the user can hardly see what is wrong. (Moore) Could use vimrun with an "-nowait" argument to only wait when an error occurs, but "command.com" doesn't return an error code. 8 When the 'shell' cannot be executed, should give an appropriate error msg. Esp. for a filter command, currently it only complains the file could not be read. 7 Add an option to add one pixel column to the character width? Lucida Console italic is wider than the normal font ("d" overlaps with next char). Opposite of 'linespace': 'columnspace'. 7 At the hit-enter prompt scrolling now no longer works. Need to use the keyboard to get around this. Pretend was hit when the user tries to scroll? 7 Scrollbar width doesn't change when selecting other windows appearance. Also background color of Toolbar and rectangle below vert. scrollbar. 7 "!start /min cmd" should run in a minimized window, instead of using "/min" as the command name. (Rogall) 6 Drawing text transparently doesn't seem to work (when drawing part cursor). 8 CTRL key doesn't always work in combination with ALT key. It does work for function keys, not for alphabetic characters. Perhaps this is because CTRL-ALT is used by Windows as AltGr? 8 CTRL-- doesn't work for AZERTY, because it's CTRL-[ for QWERTY. How do we know which keyboard is being used? 7 When scrolling, and a background color is dithered, the dither pattern doesn't always join correctly between the scrolled area and the new drawn area (Koloseike). 8 When gui_init_font() is called with "*", p_guifont is freed while it might still be used somewhere. This is too tricky, do the font selection first, then set the new font by name (requires putting all logfont parameters in the font name). Athena and Motif: 6 New Motif toolbar button from Marcin Dalecki: - When the mouse pointer is over an Agide button the red becomes black. Something with the way colors are specified in the .xpm file. - The pixmap is two pixels smaller than it should be. The gap is filled with grey instead of the current toolbar background color. 9 Can configure be changed to disable netbeans if the Xpm library is required and it's missing? 8 When using the resource "Vim*borderwidth 2" the widgets are positioned wrong. 9 XIM is disabled by default for SGI/IRIX. Fix XIM so that 'imdisable' can be off by default. 9 XIM doesn't work properly for Athena/Motif. (Yasuhiro Matsumoto) For now, keep XIM active at all times when the input method has the preediting flag. 8 X11: A menu that contains an umlaut is truncated at that character. Happens when the locale is "C", which uses ASCII instead of IS0-8859-1. Is there a way to use latin1 by default? Gnome_init() seems to do this. 8 Perhaps use fontsets for everything? 6 When starting in English and switching the language to Japanese, setting the locale with ":lang", 'guifontset' and "hi menu font=", deleting all menus and setting them again, the menus don't use the new font. Most of the tooltips work though... 7 Motif: when using a file selection dialog, the specified file name is not always used (when specifying a filter or another directory). 8 When 'encoding' is different from the current locale (e.g., utf-8) the menu strings don't work. Requires conversion from 'encoding' to the current locale. Workaround: set 'langmenu'. Athena GUI: 9 When dragging the scrollbar thumb very fast, focus is only obtained in the scrollbar itself. And the thumb is no longer updated when moving through files. 7 The file selector is not resizable. With a big font it is difficult to read long file names. (Schroeder) 4 Re-write the widget attachments and code so that we will not have to go through and calculate the absolute position of every widget every time the window is refreshed/changes size. This will help the "flashing-widgets" problem during a refresh. 5 When starting gvim with all the default colors and then typing ":hi Menu guibg=cyan", the menus change color but the background of the pullright pixmap doesn't change colors. If you type ":hi Menu guibg=cyan font=anyfont", then the pixmap changes colors as it should. Allocating a new pixmap and setting the resource doesn't change the pullright pixmap's colors. Why? Possible Athena bug? Motif GUI: - gui_mch_browsedir() is missing. 7 Use XmStringCreateLocalized() instead of XmStringCreateSimple()? David Harrison says it's OK (it exists in Motif 1.2). 8 Lesstif: When deleting a menu that's torn off, the torn off menu becomes very small instead of disappearing. When closing it, Vim crashes. (Phillipps) GUI: 9 On Solaris, creating the popup menu causes the right mouse button no longer to work for extending the selection. (Halevy) 9 When running an external program, it can't always be killed with CTRL-C. e.g., on Solaris 5.5, when using "K" (Keech). Other 'guipty' problems on Solaris 2.6. (Marley) 9 On Solaris: Using a "-geometry" argument, bigger than the window where Vim is started from, causes empty lines below the cmdline. (raf) 8 X11 GUI: When menu is disabled by excluding 'm' from 'guioptions', ALT key should not be used to trigger a menu (like the Win32 version). 8 When setting 'langmenu', it should be effective immediately. Store both the English and the translated text in the menu structure. Re-generate the translation when 'langmenu' has changed. 8 Basic flaw in the GUI code: NextScreen is updated before calling gui_write(), but the GUI code relies on NextScreen to represent the state of where it is processing the output. Need better separation of Vim core and GUI code. 8 When fontset support is enabled, setting 'guifont' to a single font doesn't work. 8 Menu priority for sub-menus for: Amiga, BeOS. 8 When translating menus ignore the part after the Tab, the shortcut. So that the same menu item with a different shortcut (e.g., for the Mac) are still translated. 8 Add menu separators for Amiga, RISCOS. 8 Add way to specify the file filter for the browse dialog. At least for browse(). 8 Add dialog for search/replace to other GUIs? Tk has something for this, use that code? Or use console dialog. 8 When selecting a font with the font dialog and the font is invalid, the error message disappears too quick. 7 More features in the find/replace dialog: - regexp on/off - search in selection/buffer/all buffers/directory when all buffers/directory is used: - filter for file name when directory is used: - subdirectory on/off - top directory browser 8 gui_check_colors() is not called at the right moment. Do it much later, to avoid problems. 8 gui_update_cursor() is called for a cursor shape change, even when there are mappings to be processed. Only do something when going to wait for input. Or maybe every 100 ms? 8 X11: When the window size is reduced to fit on screen, there are blank lines below the text and bottom scrollbar. "gvim -geometry 80x78+0+0". When the "+0+0" is omitted it works. 8 When starting an external command, and 'guipty' set, BS and DEL are mixed up. Set erase character somehow? 8 A dead circumflex followed by a space should give the '^' character (Rommel). Look how xterm does this. Also: Bednar has some code for dead key handling. Also: Nedit 5.0.2 with USE_XMIM does it right. (Gaya) 8 The compose key doesn't work properly (Cepas). Both for Win32 and X11. 7 The cursor in an inactive window should be hollow. Currently it's not visible. 7 GUI on Solaris 2.5.1, using /usr/dt/..: When gvim starts, cursor is hollow, after window lowered/raised it's OK. (Godfrey) 7 When starting GUI with ":gui", and window is made smaller because it doesn't fit on the screen, there is an extra redraw. 8 When setting font with .Xdefaults, there is an extra empty line at the bottom, which disappears when using ":set guifont=". (Chadzelek) 8 When font shape changes, but not the size, doing ":set font=" does not redraw the screen with the new font. Also for Win32. When the size changes, on Solaris 2.5 there isn't a redraw for the remaining part of the window (Phillipps). - Flashes really badly in certain cases when running remotely from a Sun. 4 Re-write the code so that the highlighting isn't changed multiple times when doing a ":hi clear". The color changes happen three or more times currently. This is very obvious on a 66Mhz 486. MSDOS/DJGPP: 9 Pressing CTRL-C often crashes the console Vim runs in. (Ken Liao) When 'bioskey' isn't set it doesn't happen. Could be a problem with the BIOS emulation of the console. Version 5.6 already had this problem. 8 DJGPP: "cd c:" can take us to a directory that no longer exists. change_drive() doesn't check this. How to check for this error? 9 The 16 bit version runs out of memory very quickly. Should find unused code and reduce static data. Resetting 'writebackup' helps to be able to write a file. 9 Crash when running on Windows 98 in a console window and pressing CTRL-C. Happens now and then. When debugging Vim in gdb this also happens. Since the console crashes, might be a bug in the DOS console. Resetting 'bioskey' avoids it, but then CTRL-C doesn't work. 9 DOS: Make CTRL-Fx and ALT-Fx work. CTRL-F1 = CE-5E, CTRL-F2 = CE-5F, .., CTRL-F10 = CE-67 ALT-F1 = CE-68, ALT-F2 = CE-69, .., ALT-F10 = CE-71 Shifted cursor keys produce same codes as unshifted keys. Use bioskey(2) to get modifier mask for . Use K_SPECIAL/KS_MODIFIER codes to insert modifier mask in input stream? Make this work like in Win32 console. Mapping things like doesn't work, because it generates an extended key code. Use a translation table? 9 Can't read an opened swap file when the "share" command has not been used. At least ignore the swap files that Vim has opened itself. 8 Use DJGPP 2.03. 8 The Dos32 version (DJGPP) can't use long file names on Windows NT. Check if new package can be used (v2misc/ntlfn08[bs].zip). 8 setlocale() is bogus. 8 Vim busy waits for new characters or mouse clicks. Should put in some sort of sleep, to avoid eating 50% of the CPU time. Test on an unpatched Windows 95 system! 8 DJGPP: when shell is bash, make fails. (Donahoe) 7 Hitting CTRL-P twice quickly (e.g., in keyword completion) on a 8088 machine, starts printer echo! (John Mullin). 7 MSDOS 16 bit version can't work with COMSPEC that has an argument, e.g.: COMSPEC=C:\WINDOWS\COMMAND.COM /E:4096 (Bradley) Caused by BCC system() function (Borland "make" has the same problem). 8 Mouse: handle left&right button pressed as middle button pressed. Add modifier keys shift, ctrl and alt. 7 When too many files are open (depends on FILES), strange things happen. The Dos16 version runs out of memory, in the Dos32 version "!ls" causes a crash. Another symptom: .swp files are not deleted, existing files are "[New file]". 7 DJGPP version doesn't work with graphics display mode. Switch to a mode that is supported? 8 DJGPP: ":mode" doesn't work for many modes. Disable them. 8 DJGPP: When starting in Ex mode, shouldn't clear the screen. (Walter Briscoe) MSDOS, OS/2 and Win32: 8 OS/2: Add backtick expansion. Undefine NO_EXPANDPATH and use gen_expand_wildcards(). 8 OS/2: Add clipboard support? See example clipbrd.exe from Alexander Wagner. 8 OS/2: Add Extended Attributes support and define HAVE_ACL. 8 OS/2: When editing a file name "foo.txt" that is actually called FOO.txt, writing uses "foo.txt". Should obtain the real file name. 8 Should $USERPROFILE be preferred above $HOMEDRIVE/$HOMEPATH? No, but it's a good fallback, thus use: $HOME $HOMEDRIVE$HOMEPATH SHGetSpecialFolderPath(NULL, lpzsPath, CSIDL_APPDATA, FALSE); $USERPROFILE SHGetSpecialFolderPath(NULL, lpzsPath, CSIDL_COMMON_APPDATA, FALSE); $ALLUSERSPROFILE $SYSTEMDRIVE\ C:\ 8 Win32 console: and don't work. (Geddes) We don't have special keys for these. Should use modifier + key. 8 Win32 console: caps-lock makes non-alpha keys work like with shift. Should work like in the GUI version. 8 Environment variables in DOS are not case sensitive. Make a define for STRCMP_ENV(), and use it when comparing environment var names. 8 Setting 'shellslash' has no immediate effect. Change all file names when it is set/reset? Or only use it when actually executing a shell command? 8 When editing a file on a Samba server, case might matter. ":e file" followed by ":e FILE" will edit "file" again, even though "FILE" might be another one. Set last used name in buflist_new()? Fix do_ecmd(), etc. 8 When a buffer is editing a file like "ftp://mach/file", which is not going to be used like a normal file name, don't change the slashes to backslashes. (Ronald Hoellwarth) Windows 95: 8 Editing a file by it's short file name and writing it, makes the long file name disappear. Setting 'backupcopy' helps. Use FindFirstFile()->cAlternateFileName in fname_case() (George Reilly). 8 Doing wildcard expansion, will match the short filename, but result in the long filename (both DJGPP and Win32). Win32 console: 9 When editing a file by its short file name, it should be expanded into its long file name, to avoid problems like these: (Mccollister) 1) Create a file called ".bashrc" using some other editor. 2) Drag that file onto a shortcut or the actual executable. 3) Note that the file name is something like BASHRC~1 4) Go to File->Save As menu item and type ".bashrc" as the file name. 5) Press "Yes" to indicate that I want to overwrite the file. 6) Note that the message "File exists (add ! to override)" is displayed and the file is not saved. Use FindFirstFile() to expand a file name and directory in the path to its long name. 8 Also implement 'conskey' option for the Win32 console version? Look at how Xvi does console I/O under Windows NT. 7 Re-install the use of $TERM and support the use of different terminals, besides the console. 8 Use of modifier doesn't work? 5.3 was OK. (Garcia-Suarez/Guckes) 9 Mapping doesn't work correctly. How to see the difference with ? 9 tmpnam() uses file in root of file system: "\asdf". That doesn't work on a Netware network drive. Use same function as for Win32 GUI? 8 In os_win32.h, HAVE_STRICMP and HAVE_STRNICMP are defined only if __GNUC__ is not defined. Shouldn't that be the other way around? 7 Use SetConsoleCP() and SetConsoleOutputCP() to implement 'termencoding'? Avoids that input and output work differently. Need to be restored when exiting. Amiga: 8 In mch_inchar() should use convert_input_safe() to handle incomplete byte sequences. 9 In mch_expandpath() a "*" is to be expanded, but "\*" isn't. Remove backslashes in result. 8 Executing a shell, only one option for 'shell' is separated. Should do all options, using white space separation. Macintosh: - GUI: gui_mch_browsedir() is missing. 7 Patch to add 'transparency' option. Disadvantage: it's slow. (Eckehard Berns, 2004 May 9) http://ecki.to/vim/TransBack-2004-05-09.diff Needs more work. Add when someone really wants it. 7 Loading the Perl library only works on OS/X 10.2 or 10.3, never on both. Load the Perl library dynamically see Python sources file dynload_mac (Jack) dynamic linking: http://developer.apple.com/technotes/tn2002/tn2064.html 8 Inputting Unicode characters does not work in the terminal. They appear to arrive as upper and lower bytes. (David Brown, 2004 April 17) 8 Typing Unicode characters doesn't work at all in the GUI. 8 inputdialog() doesn't resize when giving more text lines. (David Fishburn, 2006 Sept 28) 9 Problems in Carbon version for OS X: (Benji Fisher) - keyboard shortcuts in the menus get lost. 8 The Vim/About menu doesn't work. 8 ":gui" doesn't fork. Enabling the code in gui.c to fork causes a SEGV. 8 Define vim_mkdir() for Macintosh. 8 Define mch_writable() for Macintosh. 8 Some file systems are case-sensitive, some are not. Turn CASE_INSENSITIVE_FILENAME into an option, at least for completion. 9 When DiskLock is running, using a swap file causes a crash. Appears to be a problem with writing a file that starts with a dot. (Giacalone) 9 On G3 Mac, OS version 8, control strip causes characters messed up when scrolling (CTRL-L cleans it up). (Benji Fisher) 9 On G3 Mac, OS version 8, variable-speed scrolling doesn't work, after two seconds of scrolling the screen freezes. (Benji Fisher) 9 In mac_expandpath() check that handling of backslashes is done properly. 8 Standard Mac shortcuts are missing. (Amerige) 8 Handling of non-fixed width fonts is wrong. (Amerige) "Small" problems: - When using e_secure in do_one_cmd() mention the command being executed, otherwise it's not clear where it comes from. 9 For Turkish vim_tolower() and vim_toupper() also need to use utf_ functions for characters below 0x80. (Sertacyildiz) 9 When the last edited file is a help file, using '0 in a new Vim doesn't edit the file as a help file. 8 When an ":edit" is inside a try command and the ATTENTION prompt is used, the :catch commands are always executed, also when the file is edited normally. Should reset did_emsg and undo side effects. Also make sure the ATTENTION message shows up. Servatius Brandt works on this. 9 When using ":e ++enc=foo file" and the file is already loaded with 'fileencoding' set to "bar", then do_ecmd() uses that buffer, even though the fileencoding differs. Reload the buffer in this situation? Need to check for the buffer to be unmodified. 8 ":g//" gives "Pattern not found error" with E486. Should not use the error number, it's not a regular error message. 7 Vimtutor leaves escape sequence in terminal. This is the xterm response to requesting the version number. (Yasuhiro Matsumoto) 8 When redirecting and using ":silent" the current column for displaying and redirection can be different. Use a separate variable to hold the column for redirection. 7 The messages for "vim --help" and "vim --version" don't use 'termencoding'. - Could the hit-enter prompt be avoided when a message only overlaps the 'showcmd' area? Clear that area when the next cmd is typed. 8 When 'scrollbind' is set, a window won't scroll horizontally if the cursor line is too short. Add a word in 'scrollopt' to allow moving the cursor to longer line that is visible. A similar thing is done for the GUI when using the horizontal scrollbar. 7 VisVim can only open one file. Hard to solve: each opened file is passed with a separate invocation, would need to use timestamps to know the invocations belong together. 8 When giving a ":bwipeout" command a file-changed dialog may popup for this buffer, which is pointless. (Mike Williams) 8 On MS-Windows ":make" doesn't show output while it is working. Use the tee.exe from http://unxutils.sourceforge.net/ ? About 16 Kbyte in the UnxUtils.zip archive. Alternate one: http://www.pramodx.20m.com/tee_for_win32.htm, but Walter Briscoe says it's not as good. 8 "stl" and "stlnc" in 'fillchars' don't work for multi-byte characters. 8 When doing Insert mode completion a mapping cannot recursively call edit(), because the completion information is global. Put everything in an allocated structure? 6 Python: ":py raw_input('prompt')" doesn't work. (Manu Hack) 8 Command line completion: buffers "foo.txt" and "../b/foo.txt", completing ":buf foo" doesn't find the second one. (George V. Reilly) 7 Output for ":scriptnames" and ":breaklist" should shorten the file names: use "~/" when possible. 7 mb_off2cells() doesn't work correctly on the tail byte of a double-byte character. (Yasuhiro Matsumoto) It should return 1 when used on a tail byte, like for utf-8. Store second byte of double-byte in ScreenLines2[] (like for DBCS_JPNU) and put a zero in the second byte (like for UTF-8). 8 'backupdir' and 'directory' should use $TMPDIR, $TMP and/or $TEMP when defined. 7 Inside a function with "perl <a" and a mapping x", when typing "a" with half a second delay should not be interpreted as a keycode. (Hans Ginzel) 7 ":botright 1 new" twice causes all window heights to be changed. Make the bottom window only bigger as much as needed. 7 The Cygwin and MingW makefiles define "PC", but it's not used anywhere. Remove? (Dan Sharp) 9 User commands use the context of the script they were defined in. This causes a "s:var" argument to unexpectedly use a variable in the defining script, not the calling script. Add an argument to ":command": "-keepcontext". Do replace , so that a function in the defining script can be called. 8 The Japanese message translations for MS-Windows are called ja.sjis.po, but they use encoding cp932. Rename the file and check that it still works. 9 When a syntax region does not use "keepend" and a contained item does use "extend", this makes the outer region stop at the end of the contained region. (Lutz Eymers) Another example Nov 14 2002. 8 A very long message in confirm() can't be quit. Make this possible with CTRL-C. 7 clip_x11_own_selection() uses CurrentTime, that is not allowed. VNC X server has a problem with this. (Mark Waggoner) Remembering the timestamp of events isn't always possible. We don't get them in an xterm. GTK doesn't obtain the selection again when the timestamp differs, thus it won't work for GTK anyway. 8 When the clipboard isn't supported: ":yank*" gives a confusing error message. Specifically mention that the register name is invalid. 8 "gf" always excludes trailing punctuation characters. file_name_in_line() is currently fixed to use ".,:;!". Add an option to make this configurable? 8 'hkmap' should probably be global-local. 9 When "$" is in 'cpoptions' and folding is active, a "C" command changes the folds and resets w_lines_valid. The display updating doesn't work then. (Pritesh Mistry) 8 ":s!from!to!" works, but ":smagic!from!to!" doesn't. It sees the "!" as a flag to to the command. Same for ":snomagic". (Johan Spetz) 8 Using ":s" in a function changes the previous replacement string. Save "old_sub" in save_search_patterns()? 8 Should allow multi-byte characters for the delimiter: ":s+a+b+" where "+" is a multi-byte character. 8 When appending to a file and 'patchmode' isn't empty, a backup file is always written, even when the original file already exists. 7 When using "daw" on the last word in a file and this is a single letter, nothing is deleted. Should delete the letter and preceding white space. 9 When getting focus while writing a large file, could warn for this file being changed outside of Vim. Avoid checking this while the file is being written. 7 The message in bt_dontwrite_msg() could be clearer. 8 The script ID that is stored with an option and displayed with ":verbose set" isn't reset when the option is set internally. For example when 'foldlevel' is set from 'foldlevelstart'. 8 Also store the line number with the script ID and use it for ":verbose", so that "set nocompatible" is found when it changes other option values. When an option is set indirectly mention the command? E.g. when ":diffsplit" sets 'foldmethod'. 8 In the fileformat dialog, "Cancel" isn't translated. Add a global variable for this. (Eduardo Fernandez) 9 When editing a file with 'readonly' set, there is no check for an existing swap file. Then using ":write" (without making any changes) doesn't give a warning either. Should check for an existing swap file without creating one. 7 When 'showbreak' is set, the amount of space a Tab occupies changes. Should work like 'showbreak' is inserted without changing the Tabs. 7 When 'mousefocus' is set and switching to another window with a typed command, the mouse pointer may be moved to a part of the window that's covered by another window and we lose focus. Only move in the y direction, not horizontally? 8 When using CTRL-D after ":help", restrict the number of matches to a thousand, otherwise using CTRL-D without an argument takes too long. 8 ":hardcopy": - Using the cterm_color[] table is wrong when t_colors is > 16. - Need to handle unprintable characters. - Win32: On a B&W printer syntax highlighting isn't visible. Perform dithering to make grey text? - Add a flag in 'printoptions' to add an empty page to make the total number even. "addempty"? (Mike Williams) - Respect 'linebreak'. Perhaps also 'showbreak'? - Should interpreted CTRL-L as a page break. - Grey line numbers are not always readable. Add field in 'printoptions'. Default to black when no syntax highlighting. - Be able to print a window in diff mode. - Be able to specify a colorscheme to use for printing. And a separate one for B&W printing (if that can be detected). 8 In Visual block mode with 'lbr' set, a change command doesn't insert the text in following lines where the linebreak changes. 9 dosinst.c: The DJGPP version can't uninstall the Uninstall registry key on Windows NT. How to install a .inf file on Windows NT and how to detect that Windows NT is being used? 8 When 'virtualedit' is "block,insert" and encoding is "utf-8", selecting a block of one double-wide character, then "d" deletes only half of it. 8 When 'virtualedit' is set, should "I" in blockwise visual mode also insert in lines that don't extend into the block? 8 With 'virtualedit' set, in Insert mode just after the end of line, CTRL-O yh does not yank the last character of the line. (Pavel Papushev) Doing "hl" first appears to make it work. 8 With 'virtualedit' set it's possible to move into the blank area from 'linebreak'. 8 With 'virtualedit' set and 'selection' "exclusive", a Visual selection that ends in or after a tab, "d" doesn't delete (part of) the tab. (Helmut Stiegler) 8 With 'virtualedit' set, a blockwise Visual selection that starts and ends in a tab, "<" shifts too much. (Helmut Stiegler) 9 When jumping to a tag, the search pattern is put in the history. When 'magic' is on, the pattern may not work. Translate the pattern depending on p_magic when putting it in the history? Alternative: Store value of 'magic' in history. (Margo) 9 optwin.vim: Restoring a mapping for or is not correct for ":noremap". Add "mapcmd({string}, {mode})? Use code from ":mkexrc". 9 incsearch is incorrect for "/that//this/;//" (last search pattern isn't updated). 9 term_console is used before it is set (msdos, Amiga). 9 Get out-of-memory for ":g/^/,$s//@/" on 1000 lines, this is not handled correctly. Get many error messages while redrawing the screen, which cause another redraw, etc. 8 [ doesn't work when '*' is in 'iskeyword'. find_pattern_in_path() must escape special characters in the pattern. 8 Vim can overwrite a read-only file with ":w!". ":w" can't overwrite an existing file, "w!" can, but perhaps not a read-only file? Then use ":w!!" for that. Or ask for permission to overwrite it (if file can be made writable) and restore file to readonly afterwards. Overwriting a file for which a swap file exists is similar issue. 7 When compiled with "xterm_clipboard", startup can be slower and might get error message for invalid $DISPLAY. Try connecting to the X server in the background (forked), so that Vim starts up quicker? Connect as soon as the clipboard is to be used (Visual select mode starts, paste from clipboard) 7 X11: Some people prefer to use CLIPBOARD instead of PRIMARY for the normal selection. Add an "xclipboard" argument to the 'clipboard' option? (Mark Waggoner) 8 For xterm need to open a connection to the X server to get the window title, which can be slow. Can also get the title with "[21t", no need to use X11 calls. This returns "]l{title}\". 6 When the xterm reports the number of colors, a redraw occurs. This is annoying on a slow connection. Wait for the xterm to report the number of colors before drawing the screen. With a timeout. 8 When the builtin xterm termcap contains codes that are not wanted, need a way to avoid using the builtin termcap. 8 Xterm sends ^[[H for and ^[[F for in some mode. Also recognize these keys? Mostly useful for xterm simulators, like gnometerm. See http://dickey.his.com/xterm/xterm.faq.html#xterm_pc_style. 8 For xterm also recognize keypad up/down/left/right and insert. 8 '[ and '] should be set to start/end of line when using a linewise operator (e.g., ":w"). 8 CTRL-A can't handle big "long" numbers, they become negative. Check for "-" character, if not present, use unsigned long. 8 Make it possible to disable the special meaning of "#" in the first column for ">>". 8 Add suspending with CTRL-Z at the "more" prompt, and when executing a long script in do_cmdline(). 8 When using 'hidden', many swap files will be open. When Vim runs into the maximum number of open files, error messages will appear. Detect that this problem is present, and close any hidden files that don't have changes. 8 With 'viminfo' set such that the ".viminfo" file is written on a FAT filesystem, an illegal file name may be created: ".vim". 8 For each buffer that is opened, the viminfo file is opened and read to check for file marks. This can be slow. 7 In xterm, recognize both vt100 and vt220 cursor keys. Change add_termcode() to not remove an existing entry for a name, when it's needed. Need a generic solution to recognize different codes for the same key. 8 Core dump within signal function: gdb doesn't show stack backtrace! Option to skip catch_signals()? 9 Repeating a "cw" with "." doesn't work if the text was pasted from the clipboard. (Thomas Jones) It's because the menu/toolbar item exits Insert mode and uses "gP". How to fix this without breaking inserting a block of text? 8 In Replace mode pasting from the clipboard (using menu or toolbar) inserts all the text. Add ":rmenu"? 8 Pasting with the mouse in Replace mode inserts the text, instead of overwriting, when it is more than one line. Same for using . 9 CTRL-E and CTRL-Y don't work in small window when 'so' is 4 and lines are wrapping (Acevedo/in.226). E.g., when using CTRL-E, window height 7, window might actually scroll down when last line of buffer is displayed. --> Remember if the previous command was "cursor follows screen" or "screen follow cursor" and use this in cursupdate(). 7 tilde_replace() can only handle "~/", should also do "~user/". Get the list of home directories (from /etc/passwd? Use getpwent()) and use some clever algorithm to match a path with that. Find common strings in the list? 8 When dragging status line with mouse, sometimes a jump when first clicking on the status line (caused by 'winheight'). Select window on button up, instead of on button down. 8 Dragging the status line doesn't scroll but redraw. 9 Evaluating 'statusline' in build_stl_str_hl() does not properly check for reaching the end of the available buffer. Patch to dynamically allocate the buffer for % items. (Eric Arnold, 2006 May 14) 8 When performing incremental search, should abort searching as soon as a character is typed. 8 When the value of $MAKE contains a path, configure can't handle this. It's an autoconf bug. Remove the path from $MAKE to work around it. 8 How to set VIMRC_FILE to \"something\" for configure? Why does this not work: CFLAGS='-DVIMRC_FILE=\"/mydir/myfile\"' ./configure 8 The temporary file is sometimes not writable. Check for this, and use an alternate name when it isn't. Or add the 'temptemplate' option: template for the temp file name ":set temptemplate=/usr/tmp/?????.tmp". Also: Win32 version uses Windows temp directory, which might not work for cygwin bash. 7 Get error "*, \+ or \( operand could be empty" for pattern "\(.\)\1\{3}". Remember flags for backreferences. 7 When switching to Daylight Saving Time, Vim complains that a file has been changed since last read. Can we use a function that uses GMT? 7 When completing an environment variable after a '$', check for file names that contain a '$' after all have been found. 8 When "cm" termcap entry is missing, starting gvim shouldn't complain about it. (Lohner) Try out with "vt100" entry, cm replaced with cX. 7 When an include file starts with "../", the check for already visiting this file doesn't work. Need to simplify the file name. 7 The names and comments for the arguments of do_browse() are confusing. "dflt" isn't the default file name when "initdir" is not NULL and "initdir" is the default path to be used. 7 When 'scrolloff' is exactly half the window height, "j" causes a scroll of two lines at a time. "k" doesn't do this. (Cory T. Echols) 8 When write_viminfo() is used while there are many orphaned viminfo tempfiles writing the viminfo file fails. Give a clear error message so that the user knows he has to delete the files. 7 It's possible to redefine a script-local function with ":func 123_Test()". (Krishna) Disallow this. I can't reproduce these (if you can, let me know how!): 9 NT 4.0 on NTFS file system: Editing ".bashrc" (drag and drop), file disappears. Editing ".xyz" is OK. Also, drag&drop only works for three files. (McCollister) Problems that will (probably) not be solved: - GTK: when using the popup menu with spelling suggestions and releasing the right mouse button before the menu appears selecting an item with the right mouse button has no effect. GTK does not produce an event for this. - xterm title: The following scenario may occur (esp. when running the Vim test script): Vim 1 sets the title to "file1", then restores the title to "xterm" with an ESC sequence when exiting. Vim 2 obtains the old title with an X library call, this may result in "file1", because the window manager hasn't processed the "xterm" title yet. Can apparently only be worked around with a delay. - In a terminal with 'mouse' set such that the mouse is active when entering a command line, after executing a shell command that scrolls up the display and then pressing ":": Selecting text with the mouse works like the display wasn't scrolled. Vim doesn't know how much the external command scrolled up the display. Use Shift to select text. - X windows: When $DISPLAY points to a X server where there is no access permission, trying to connect to the X server causes an error message. XtOpenDisplay() prints this directly, there is no way to avoid it. - X windows: Setting 'guifontset' to an illegal value sometimes crashes Vim. This is caused by a fault in a X library function, can't be solved in Vim. - Win32 tcl: has("tcl") hangs when the tcl84.dll is from cygwin. - Motif: When adding a menu item "Find this &Symbol", the "s" in "this" will be underlined, instead of in "Symbol". Motif doesn't let us specify which character gets the highlighting. - Moving the cursor removes color in color-xterm. This is a color-xterm problem! color-xterm ver. 6.1 beta 3 and later work properly. - In zsh, "gvim&" changes the terminal settings. This is a zsh problem. (Jennings) - Problem with HPterm under X: old contents of window is lost (Cosentino). - Amiga: When using quickfix with the Manx compiler we only get the first 25 errors. How do we get the rest? - Amiga: The ":cq" command does not always abort the Manx compiler. Why? - Linux: A file with protection r--rw-rw- is seen readonly for others. The access() function in GNU libc is probably wrong. - MSDOS: When using smartdrive with write-back buffering, writing to a readonly floppy will cause problems. How to test for a writable floppy first? - MSDOS: Both 16 and 32 bit versions: File name expansion doesn't work for names that start with a dot. These used to be illegal file names. - When doing a CTRL-Z and typing a command for the shell, while Vim is busy (e.g. writing a file), the command for the shell is sometimes eaten by Vim, because the terminal mode is changed from RAW to CBREAK. - An old version of GNU tgoto can't handle the terminfo code for "AF". The "%p1" is interpreted as "%p" and "1", causing color not to be working. Fix: Change the "%p1" in the "AF" and "AB" terminfo entries to "%p". (Benzinger). - When running an external command from the GUI, typeahead is going to that program, not to Vim. It looks like the shell eats the characters, Vim can't get back what the external command didn't use. - Win32 GUI: Error code from external command not returned in shell_error. It appears that cmd.exe and command.com don't return an error code. - Win32 GUI: The Toolbar is a bit too high when the flat style is being used. We don't have control over the height of the Toolbar. - Win32: All files created on the day of switching from winter to summer time cause "changed since editing started" messages. It goes away when the file is written again the next day, or the timezone is adjusted. DJGPP version is OK. (Zaimi) Looks like a problem with the Win32 library. Rebooting doesn't help. Time stamps look OK in directory. (Penn) Is this on FAT (stores wall clock time) or NTFS (stores UTS)? - Win32, MS-Windows XP: $HOME uses the wrong drive when the user profiles are not on the boot disk. This is caused by a wrong value of $HOMEDRIVE. This is a bug in XP, see MSKB article 818134. - SunOS 5.5.1 with Motif: The file open dialog does not have a horizontal scroll bar for the "files" selection. This is a problem in the Motif libraries, get a patch from Sun. - Solaris 2.6 with GTK and Perl: gvim crashes when started. Problem with X input method called from GDK code. Without Perl it doesn't crash. - VMS: Vimdiff doesn't work with the VMS diff, because the output looks different. This makes test 47 fail. Install a Unix-compatible diff. - VMS v7.1 and older: Tests 21 and 32 fail. From VMS v7.1-2 and newer Vim does not have this behavior. (Zoltan Arpadffy) - Win32 GUI: mouse wheel always scrolls rightmost window. The events arrive in Vim as if the rightmost scrollbar was used. - GTK with Gnome: Produces an error message when starting up: Gdk-WARNING **: locale not supported by C library This is caused by the gnome library gnome_init() setting $LC_CTYPE to "en_US". Not all systems support this locale name, thus causing the error. Hopefully a newer version of GTK/Gnome fixes this problem. - GTK 2: With this mapping the hit-enter prompt is _sometimes_ below the screen, at other times there is a grey area below the command line: :nmap :if &guioptions=~'m' \| set guioptions-=m \| else \| set guioptions+=m \| endif - GTK: When pasting a selection from Vim to xclipboard gvim crashes with a ABRT signal. Probably an error in the file gdkselection.c, the assert always fails when XmbTextListToTextProperty() fails. (Tom Allard) - GTK 2: gives an assertion error for every non-builtin icon in the toolbar. This is a GTK 2.4.x bug, fixed in GTK 2.4.2. (Thomas de Grenier de Latour) - When using an xterm that supports the termresponse feature, and the 't_Co' termcap option was wrong when Vim started, it will be corrected when the termresponse is received. Since the number of colors changes, the highlighting needs to be initialized again. This may cause colors defined in the vimrc file to be lost. - On Windows NT 4.0 the number of files passed to Vim with drag&drop and "Edit with Vim" is limited. The maximum command line length is 255 chars. --------------------- extensions and improvements ---------------------- *extensions-improvements* Didn't make it into Vim 7.0: - Add COLUMN NUMBERS to ":" commands ":line1,line2[col1,col2]cmd". Block can be selected with CTRL-V. Allow '$' (end of line) for col2. - Add DEBUGGER INTERFACE. Implementation for gdb by Xavier de Gaye. Should work like an IDE. Try to keep it generic. Now found here: http://clewn.sf.net. And the idevim plugin/script. To be able to start the debugger from inside Vim: For GUI run a program with a netbeans connection; for console: start a program that splits the terminal, runs the debugger in one window and reconnect Vim I/O to the other window. Wishes for NetBeans commands: - make it possible to have 'defineAnnoType' also handle terminal colors. - send 'balloonText' events for the cursor position (using CursorHold ?) in terminal mode. - ECLIPSE plugin. Problem is: the interface is very complicated. Need to implement part in Java and then connect to Vim. Some hints from Alexandru Roman, 2004 Dec 15. Should then also work with Oracle Jdeveloper, see JSR 198 standard http://www.jcp.org/en/jsr/detail?id=198. Eclim does it: http://eclim.sourceforge.net/ (Eric Van Dewoestine) Plugin that uses a terminal emulator: http://vimplugin.sf.net And another one: http://www.satokar.com/viplugin/index.php - STICKY CURSOR: Add a way of scrolling that leaves the cursor where it is. Especially when using the scrollbar. Typing a cursor-movement command scrolls back to where the cursor is. - Running a shell command from the GUI still has limitations. Look into how the terminal emulator of the Vim shell project can help: http://vimshell.wana.at - Add Lua interface? (Wolfgang Oertl) 8 Add a command to jump to a certain kind of tag. Allow the user to specify values for the optional fields. E.g., ":tag size type=m". Also allow specifying the file and command, so that the result of taglist() can be used. - X11: Make it possible to run Vim inside a window of another program. This can be done with XReparentWindow(). But how exactly? Documentation: 8 List of Vim runtime directories. dotvim.txt from Charles Campbell, 2007 Feb 20. 8 The GUI help should explain the Find and Find/Replace dialogs. Add a link to it from ":promptrepl" and ":promptfind". 8 List of options should mention whether environment variables are expanded or not. 8 Extend usr_27.txt a bit. (Adam Seyfarth) 7 Add a section on debugging scripts in the user manual. 9 Make the Reference Manual more precise. For each command mention: - change to cursor position and curswant - if it can be undone (u/CTRL-R) and redone (.) - how it works for folded lines - how it works with multi-byte characters 9 In change.txt, remark about Javadoc isn't right. Right alignment would work too. 8 Spread the windows commands over the other files. For example, ":stag" should be with ":tag". Cross-link with tags to avoid too much double text. 8 Add tags for all features, e.g. "gui_running". 7 MS-Windows: When a wrong command is typed with an ALT key, give a hint to look at the help for 'winaltkeys'. 7 Add a help.vim plugin that maps to jump to the next tag in || and (and ) to the previous tag. - Check text editor compendium for vi and Vim remarks. Help: - First try using the ":help" argument literally, before using it as a pattern. And then match it as part of a tag. - When a help item has multiple matches make it possible to use ":tn" to go to the other matches. - Support a way to view (and edit) .info files. - Default mapping for help files: to position cursor on next |:tag|. - Implement a "sticky" help window, some help text lines that are always displayed in a window with fixed height. (Guckes) Use "~/.vimhelp" file, user can edit it to insert his favorite commands, new account can contain a default contents. - Make 'winminheight' a local option, so that the user can set a minimal height for the help window (and other windows). - ":help :s^I" should expand to ":help :substitute". - Make the help key () context sensitive? - Learn mode: show short help while typing commands. User Friendlier: 8 Windows install with NSIS: make it possible to do a silent install, see http://nsis.sourceforge.net/Docs/Chapter4.html#4.12 8 Windows install with install.exe: Use .exe instead of .bat files for links, so that command line arguments are passed on unmodified? (Walter Briscoe) 8 Windows install: Be able to associate Vim with a selection of file types? 8 Windows uninstall: Have uninstal.c delete the vimfiles directories that dosinst.c creates. List the contents of the directory (recursively) if the user asks for it. Requires an implementation of "rm -rf". 8 Remember the name of the vimrc file that was used (~/.vimrc, $VIM/_vimrc, $HOME/_vimrc, etc.) and add "edit vimrc" to the File menu. - Add a way to save local settings and mappings into a new plugin file. ":mkplugin "? 8 Add ":plugininstall" command. Can be used to install a plugin file that includes documentation. Let the user select a directory from 'runtimepath'. " Vim plugin
" >>> plugin help start <<< - Add mappings local to a window: ":map ..."? 9 Add buffer-local menu. Should offer a choice between removing the menu or disabling it. Be careful that tear-offs don't disappear (keep one empty item?). Alternative: use BufEnter and BufLeave autocommands. 8 make a vimtutor script for Amiga and other systems. 7 Add the arguments for configure to the ":version" output? 7 When Vim detects a file is being edited elsewhere and it's a gvim session of the same user it should offer a "Raise" button, so that the other gvim window can be displayed. (Eduard) 8 Support saving and restoring session for X windows? It should work to do ":mksession" and use "-S fname" for the restart command. The gui_x11_wm_protocol_handler() already takes care of the rest. global_event_filter() for GTK. Tab pages: 9 GUI implementation for the tab pages line for other systems. 7 GUI: Control over the appearance of the text in the labels (bold, color, font, etc.) 9 Make it possible to drag a tab page label to another position with the mouse. 8 Make GUI menu in tab pages line configurable. Like the popup menu. 8 balloons for the tab page labels that are shortened to show the full path. 8 :tabmove +N move tab page N pages forward 8 :tabmove -N move tab page N pages backward 7 :tabdup duplicate the tab with all its windows. 7 Option to put tab line at the left or right? Need an option to specify its width. It's like a separate window with ":tabs" output. 7 Add local variables for each tab page? 8 Add local options for each tab page? E.g., 'diffopt' could differ between tab pages. 7 Add local highlighting for each tab page? 7 Add local directory for tab pages? How would this interfere with window-local directories? Spell checking: - Support more regions? Caolan McNamara argues it's needed for es_XX. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=219777 - Unicode defines another quote character: 0x2019. Use it as an equivalent of a single quote, thus use it as a word character like a quote and match with words, replacing the curly quote with a single quote. - Could filter é things for HTML before doing spell checking. Similarly for TeX. - The Hungarian spell file uses four extra characters in the FOL/UPP/LOW items than other spell files with the ISO-8859-2 encoding, that causes problem when changing 'spelllang'. There is no obvious way to fix this. - Considering Hunspell 1.1.4: What does MAXNGRAMSUGS do? Is COMPLEXPREFIXES necessary when we have flags for affixes? - Support spelling words in CamelCase as if they were two separate words. Requires some option to enable it. (Timothy Knox) - There is no Finnish spell checking file. For openoffic Voikko is now used, which is based on Malaga: http://home.arcor.de/bjoern-beutel/malaga/ (Teemu Likonen) 8 ":mkspell" still takes much too long in Hungarian dictionary from hunspell. Only solution appears to be to postpone secondary suffixes. 8 Handle postponed prefix with COMPOUNDPERMITFLAG or COMPOUNDFORBIDFLAG. WFP_COMPPERMIT and WFP_COMPFORBID 8 implement use of in .spl file: implement CHECKCOMPOUNDREP: when a compound word seems to be OK apply REP items and theck if the result is a valid word. implement CHECKCOMPOUNDDUP implement CHECKCOMPOUNDTRIPLE Add CHECKCOMPOUNDCASE: when compounding make leading capital lower case. How is it supposed to work? 8 implement using CHECKCOMPOUNDPATTERN: match words with sl_comppat[]. - Add a command the repeats ]s and z=, showing the misspelled word in its context. Thus to spell-check a whole file. - suggestion for "KG" to "kg" when it's keepcase. - For flags on affixes: Use a "AFFCOMPSET" flag; means the compound flags of the word are not used. - Support breakpoint character ? 0xb7 and ignore it? Makes it possible to use same wordlist for hyphenation. - Compound word is accepted if nr of words is <= COMPOUNDWORDMAX OR nr of syllables <= COMPOUNDSYLMAX. Specify using AND in the affix file? - NEEDCOMPOUND also used for affix? Or is this called ONLYINCOMPOUND now? Or is ONLYINCOMPOUND only for inside a compound, not at start or end? - Do we need a flag for the rule that when compounding is done the following word doesn't have a capital after a word character, even for Onecap words? - New hunspell home page: http://hunspell.sourceforge.net/ - Version 1.1.0 is out now, look into that. - Lots of code depends on LANG, that isn't right. Enable each mechanism in the affix file separately. - Example with compounding dash is bad, gets in the way of setting COMPOUNDMIN and COMPOUNDWORDMAX to a reasonable value. - PSEUDOROOT == NEEDAFFIX - COMPOUNDROOT -> COMPOUNDED? For a word that already is a compound word Or use COMPOUNDED2, COMPOUNDED3, etc. 8 Alternate Dutch word list at www.nederlandsewoorden.nl (use script to obtain). But new Myspell wordlist will come (Hagen) - CIRCUMFIX: when a word uses a prefix marked with the CIRCUMFIX flag, then the word must also have a suffix marked with the CIRCUMFIX flag. It's a bit primitive, since only one flag is used, which doesn't allow matching specific prefixes with suffixes. Alternative: PSFX {flag} {pchop} {padd} {pcond} {schop} {sadd}[/flags] {scond} We might not need this at all, you can use the NEEDAFFIX flag and the affix which is required. - When a suffix has more than one syllable, it may count as a word for COMPOUNDWORDMAX. - Add flags to count extra syllables in a word. SYLLABLEADD1 SYLLABLEADD2, etc.? Or make it possible to specify the syllable count of a word directly, e.g., after another slash: /abc/3 - MORPHO item in affix file: ignore TAB and morphological field after word/flags and affix. - Implement multiple flags for compound words and CMP item? Await comments from other spell checking authors. - Also see tklspell: http://tkltrans.sourceforge.net/ 8 Charles Campbell asks for method to add "contained" groups to existing syntax items (to add @Spell). Add ":syntax contains {pattern} add=@Spell" command? A bit like ":syn cluster" but change the contains list directly for matching syntax items. - References: MySpell library (in OpenOffice.org). http://spellchecker.mozdev.org/source.html http://whiteboard.openoffice.org/source/browse/whiteboard/lingucomponent/source/spellcheck/myspell/ author: Kevin Hendricks 8 It is currently not possible to mark "can not" as rare, because "can" and "not" are good words. Find a way to let "rare" overrule "good"? 8 Make "en-rare" spell file? Ask Charles Campbell. 8 The English dictionaries for different regions are not consistent in their use of words with a dash. 7 Insert mode completion mechanism that uses the spell word lists. 8 Add hl groups to 'spelllang'? :set spelllang=en_us,en-rare/SpellRare,en-math/SpellMath More complicated: Regions with different languages? E.g., comments in English, strings in German (po file). Diff mode: 8 Use diff mode to show the changes made in a buffer (compared to the file). Use an unnamed buffer, like doing: new | set bt=nofile | r # | 0d_ | diffthis | wincmd p | diffthis Also show difference with the file when editing started? Should show what can be undone. (Tom Popovich) 7 Add cursor-binding: when moving the cursor in one diff'ed buffer, also move it in other diff'ed buffers, so that CTRL-W commands go to the same location. Folding: (commands still available: zI zJ zK zp zP zq zQ zV zy zY; secondary: zB zS zT zZ, z=) 8 Vertical folds: looks like vertically split windows, but the cursor moves through the vertical separator, separator moves when scrolling. 8 Add "z/" and "z?" for searching in not folded text only. 9 Add search pattern item to only match in closed or open fold and/or fold with certain level. Allows doing ":g/pat/cmd" to work on closed folds. 8 Add different highlighting for a fold line depending on the fold level. (Noel Henson) 7 Use "++--", "+++--" for different levels instead of "+---" "+----". 8 When a closed fold is displayed open because of 'foldminlines', the behavior of commands is still like the fold is closed. How to make the user aware of this? 8 Add an option 'foldskip' with values like 'foldopen' that specifies which commands skip over a closed fold. 8 "H" and "L" count buffer lines instead of window lines. (Servatius Brandt) 8 Add a way to add fold-plugins. Johannes Zellner has one for VB. 7 When using manual folding, the undo command should also restore folds. - Allow completely hiding a closed fold. E.g., by setting 'foldtext' to an empty string. Require showing a character in 'foldcolumn' to avoid the missing line goes unnoticed. How to implement this? - When pressing the down arrow of a scrollbar, a closed fold doesn't scroll until after a long time. How to make scrolling with closed folds smoother? - When creating a session, also store folds for buffers in the buffer list, using the wininfo in wi_folds. - When currently editing the first file in the argument list the session file can contain: args version.c main.c edit version.c Can editing version.c twice be avoided? - 'foldmethod' "textobject": fold on sections and paragraph text objects. - Add 'hidecomment' option: don't display comments in /* */ and after //. Or is the conceal patch from Vince Negri a more generic solution? - "zuf": undo change in manual fold. "zUf" redo change in manual fold. How to implement this? - "zJ" command: add the line or fold below the fold in the fold under the cursor. - 'foldmethod' "syntax": "fold=3" argument: set fold level for a region or match. - Apply a new foldlevel to a range of lines. (Steve Litt) 8 Have some way to restrict commands to not folded text. Also commands like searches. Multi-byte characters: - When editing a file with both utf-8 and latin1 text Vim always falls back to latin1. Add a command to convert the latin1 characters to utf-8? :unmix utf-8,latin1 filename Would only work when 'encoding' is utf-8. 9 When the tail byte of a double-byte character is illegal (e.g., a CR), the display is messed up (Yasuhiro Matsumoto). Should check for illegal double-byte characters and display them differently (display each single byte). 8 Add an item in 'fileencodings' to check the first lines of a file for the encoding. See Python PEP: http://www.python.org/peps/pep-0263.html. To avoid getting a wrong encoding only accept something Emacs-like: "-*- coding: enc-na_me.foo -*-" and "-*- coding= enc-na_me.foo -*-" Match with "-\*-\s*coding[:=]\s*\([::word::-_.]\+\)\s*-\*-" and use first item. 8 Add an item in 'fileencodings' to check the first line of an XML file for the encoding. Or "charset=UTF-8"? For HTML look for "charset=utf-8". 8 The quickfix file is read without conversion, thus in 'encoding'. Add an option to specify the encoding of the errorfile and convert it. Also for ":grep" and ":helpgrep". More generic solution: support a filter (e.g., by calling a function). 8 When a file was converted from 'fileencoding' to 'encoding', a tag search should also do this on the search pattern. (Andrzej M. Ostruszka) 8 When filtering changes the encoding 'fileencoding' may not work. E.g., when using xxd and 'fileencoding' is "utf-16". Add an option to set a different fileencoding for filter output? 7 When converting a file fails, mention which byte could not be converted, so that the user can fix the problem. 8 Add configure option to be able to disable using the iconv library. (Udo Schweigert) 9 'aleph' should be set to 1488 for Unicode. (Zvi Har'El) 8 Should add test for using various commands with multi-byte characters. 8 'infercase' doesn't work with multi-byte characters. 8 toupper() function doesn't handle byte count changes. 7 Searching and composing characters: When searching, should order of composing characters be ignored? Add special item to match with a composing character, zero-width, so that one can replace a base character and keep the composing characters. Add a special item to match with a composing character, so that composing characters can be manipulated. Add a modifier to ignore composing characters, only compare base characters. Useful for Hebrew (Ron Aaron) 8 Should implement 'delcombine' for command line editing. 8 Detect overlong UTF-8 sequences and handle them like illegal bytes. 8 ":s/x/\u\1/" doesn't work, making uppercase isn't done for multi-byte characters. 8 UTF-8: "r" in Visual mode doesn't take composing characters. 8 UTF-8: When there is a precomposed character in the font, use it instead of a character and a composing character. See xterm for an example. 7 When a character can't be displayed, display its digraph instead. 'display' option to specify this. 7 Use ideas for nl_langinfo() from Markus Kuhn in enc_default(): (www.cl.cam.ac.uk/~mgk25/ucs/langinfo.c) - GTK and Win32: Allow selecting fonts for 'guifontset' with the fontselector somehow. - GTK and Win32: make it possible to set the font for the menu to make it possible to have 'encoding' different from the current locale. - dbcs_class() only works for Japanese and Korean. Implement this for other encodings. The "euc-jp" and "euc-kr" choices might be wrong. - Find some way to automatically select the right GUI font or fontset, depending on the default value of 'encoding'. Irrelevant in the GTK+ 2 GUI so long as UTF-8 is used. For Windows, the charset_pairs[] table could be used. But how do we know if a font exists? - Do keyboard conversion from 'termencoding' to 'encoding' with convert_input() for Mac GUI and RiscOS GUI. - Add mnemonics from RFC1345 longer than two characters. Support CTRL-K _{mnemonic}_ 7 In "-- INSERT (lang) --" show the name of the keymap used instead of "lang". (Ilya Dogolazky) - Make 'langmap' accept multi-byte characters. Patch from Konstantin Korikov, 2006 Oct 15. - Make 'breakat' accept multi-byte characters. Problem: can't use a lookup table anymore (breakat_flags[]). Simplistic solution: when 'formatoptions' contains "m" also break a line at a multi-byte character >= 0x100. - Do we need the reverse of 'keymap', like 'langmap' but with files and multi-byte characters? E.g., when using a Russian keyboard. - Add the possibility to enter mappings which are used whenever normal text could be entered. E.g., for "f" command. But not in Normal mode. Sort of opposite of 'langmap'. Use ":tmap" command? - When breaking a line, take properties of multi-byte characters into account. The "linebreak" program from Bruno Haible can do it: ftp://ftp.ilog.fr/pub/Users/haible/gnu/linebreak-0.1.tar.gz But it's very complicated... Printing: 7 Implement "undercurl" for printing. - Add "page width" to wrap long lines. - Win32: use a font dialog for setting 'printfont'. Can reuse the code for the 'guifont' dialog, put the common code in a separate function. - Add the file timestamp to the page header (with an option). (George Reilly) - Win32: when 'printfont' is empty use 'guifont'. - Unix: Use some dialog box to do the obvious settings (paper size, printer name, portrait/landscape, etc). - PostScript: Only works for text that can be converted to an 8-bit character set. How to support Unicode fully? - Allow specifying the paper size, instead of using a standard size. Same units as for the margins. - Support right-to-left text? 8 Make the foreground color darkening function preserve the hue of the color. Syntax highlighting: 8 Make ":syn off" use 'runtimepath' instead of $VIMRUNTIME. (Gary Johnson) Should do the same for ":syn on" and ":syn manual". 8 Support "containedin" argument for ":syn include", so that the defined cluster can be added to existing syntax items. 8 C syntax: Don't highlight {} as errors inside () when used like this: "({ something })", often used in GCC code. 7 Add a "startgroup" to a region. Used like "nextgroup" inside the region, preferred item at the start of the region. (Charles Campbell) 8 When editing a new file without a name and giving it a name (by writing it) and 'filetype' is not set, detect the filetype. Avoid doing it for ":wq file". 7 For "nextgroup" we have skipwhite, skipnl and skipempty. It would be really nice to be able to skip with a pattern. Or skip with a syntax group. (Nikolai Weibull, 2007 Feb 27) 8 Make conversion to HTML faster (Write it in C or pre-compile the script). 9 There is still a redraw bug somewhere. Probably because a cached state is used in a wrong way. I can't reproduce it... 7 Be able to change only the background highlighting. Useful for Diff* and Search highlighting. 7 When 'number' is set highlight the number of the current line. Must be enabled with an option, because it slows down display updating. 8 Allow the user to add items to the Syntax menu sorted, without having to change this for each release. 8 Add a "matchcontains" for regions: items contained in the start or end pattern, but not in the body. 8 Add a "keepend-contained" argument: Don't change the end of an item this one is contained in. Like "keepend" but specified on the contained item, instead of the containing item. 8 cpp.vim: In C++ it's allowed to use {} inside (). 8 Some syntax files set 'iskeyword'. When switching to another filetype this isn't reset. Add a special keyword definition for the syntax rules? When this is done, use vim.vim syntax highlighting for help file examples, but without ":" in 'iskeyword' for syntax. 8 Add specific syntax item to match with parens/braces that don't have a "%" match. :syntax nomatch cMatchError (,{,[,),},] [contained] 8 Highlight the text between two matching parens (e.g., with a grey background) when on one of the parens or in between them. Option for the matchparen plugin? 8 Add a command to jump to the next character highlighted with "Error". 8 When using a cterm, and no ctermfg or ctermbg are defined, use start/stop sequences. Add remark in docs that :if 'term' == "term-name" should be used. 8 Add @spell cluster to String and Comment groups for many languages. Will allow spell checking. (Fleiner) 8 When listing syntax items, try to sort the keywords alphabetically. And re-insert the [] if possible. 8 Make it possible to use color of text for Visual highlight group (like for the Cursor). 8 It would be useful to make the highlight group name an expression. Then when there is a match, the expression would be evaluated to find out what highlight group to use. Could be used to check if the shell used in a password file appears in /etc/shells. (Nikolai Weibull) syn match =s:checkShell(v:match) contained 'pattern' 8 Make it possible to only highlight a sub-expression of a match. Like using "\1" in a ":s" command. 8 Support for deleting syntax items: :syn keyword cTodo remove this :syn match cTodo remove "pattern" :syn region cString remove start="this" end="that" 8 Add possibility to sync on something else, when the syncing in one way doesn't find match. For HTML: When no {script} is found, try looking for a '<'. (Fleiner) 7 Replace the synchronizing method with a state machine specification? Should be able to start at any line in the file, search forwards or backwards, and use the result of matching a pattern. 7 Use parsing like awk, so that e.g., a ( without a matching ) can be detected. 8 Make it possible to use "inverted" highlighting, invert the original character. For Visual mode. (xterm-selection already does this). 8 Highlight non-printable characters with "SpecialChar", linked to "Special". Display them with the digraph characters, if possible. 8 Highlight the clipboard-selection with a highlight group. 8 Be able to reset highlighting to its original (default) values. 7 Be able to write current highlighting to a file as commands, similar to ":mkvimrc". 8 Improve c.vim: - Add check for unterminated strings, with a variable to switch it on: "c_strict_ansi". - Detect unbalanced "#endif". Requires looking back a long way... 8 Add an option to restrict the updating of syntax highlighting to the current line while in Insert mode. 8 When guessing value of 'background', the syntax file has already been loaded (from the .gvimrc). After changing 'background', load it again? 8 Add ":syn resync" command, to re-parse the whole file until the current display position. 8 Should support "me" offset for a region start pattern. To be used to allow searching for the end pattern inside the match of the end pattern. Example: syn region pikeXX start="([^{]" end=")" should work on "()". 8 When using a regexp for "contains=", should delay matching with it until redrawing happens. Set a flag when a group is added, check this flag when highlighting starts. 8 Some terminals can display colors like the GUI. Add some setting to use GUI colors for the terminal? With something to define the escape sequence. 7 It's possible for an item to be transparent, so that the colors of an item lower on the stack is used. Also do this with highlighting, so that the user can set transparent highlighting? E.g. a number in a C comment would get the color of a comment, a number in an assignment Normal. (Nikolai Weibull) 7 Add "semitrans": Add highlighting. E.g., make the text bold, but keep the colors. And add colors, so that Green+Red becomes Yellow. E.g. for this html: bold text italic+bold text italic text 7 Wild idea: Not only set highlighting, but also change what is displayed (e.g., remove characters, so that "bold" can be shown as "bold"): :syn region boldstuff start="" display="" end="" display="" 7 CTRL-] checks the highlight group for finding out what the tag is. 7 Add an explanation how a list of words can be used to highlight misspelled words. 8 Add more command line completion for :syntax. 8 Add more command line completion for :highlight. 8 Add more command line completion for :sign. 7 Should find a better way to parse the :syntax and :highlight commands. Use tables or lists that can be shared by parsing for execution and completion? 8 Add ColorSchemePost autocommand event, so that scripts can set up their highlighting. (Salman Halim) 7 Add a few sets of colors (e.g. Borland Turbo C one). With a menu to select one of the sets. 8 Add offsets to sub-matches: "\(a*\) *"he=e1-1 'e' is end of match 'e1' is end of sub-match 1, 's2' is start of submatch 2, etc. 8 In Insert mode, when there are typeahead characters, postpone the highlighting (for "." command). 8 Syncing on comments isn't 100% correct when / / lines mix with / * and * /. For example: What about a line that starts with / / and contains * /? 8 Ignore / * and * / inside strings, when syncing. 7 Build a few more syntax files from the file "/usr/share/misc/vgrindefs": ISP, LDL, Icon, ratfor. And check "nedit/source/highlight.c". 6 Add possibility to have background color continue until the right edge of the window. Useful for comment blocks and function headings. (Rogall) - Make it possible to add "contains" items for all items in a group. Useful when extending an already existing syntax file. - Add line-continuation pattern for non-syncing items too? - Add possibility to highlight the whole line, including the right margin (for comment blocks). - Add 'hlmatch' option: List of flags: 'c': highlight match for character under the cursor. 'b': highlight the previous (, and its match. 'a': highlight all text from the previous ( until its match. Also for {}, <>, etc.? 'e': highlight all braces without a match (slow?) OR: add an argument "cursor" to the syntax command, which means that the region/match/keyword is only highlighted when the cursor is on it. (Campbell) Or do it like Elvis: define text objects and how to highlight them around the cursor. (Iain Truskett) 7 Make it possible to use all words in the tags files as Keyword. Can also be done with a script (but it's slow). 7 Make it possible to call a ":" command when a match is found. Should allow for adding keywords from the text (e.g. variables that are set). And allows for sections with different highlighting. 7 Add highlight group for commandline: "Commandline". Make sure it highlights the command line while typing a command, and any output from messages. And external commands? 8 Make a version that works like less, but with highlighting: read stdin for text, exit at end of file, don't allow editing, etc. moreim? lessim? 7 SpecialKey highlighting overrules syntax highlighting. Can't give an unprintable char another color. Would be useful for ^M at end of line. Built-in script language: 7 Execute a function with standard option values. No need to save and restore option values. Especially useful for new options. Problem: how to avoid a performance penalty (esp. for string options)? 8 Add referring to key options with "&t_xx". Both for "echo &t_xx" and ":let &t_xx =". Useful for making portable mappings. - Add ":let var ?= value", conditional assignment. Patch by Dave Eggum, 2006 Dec 11. - range for ":exec", pass it on to the executed command. (Webb) 7 ":include" command: just like ":source" but doesn't start a new scriptID? Will be tricky for the list of script names. 8 Have a look at VSEL. Would it be useful to include? (Bigham) 8 Add ":fungroup" command, to group function definitions together. When encountered, all functions in the group are removed. Suggest using an obscure name to avoid name clashes. Require a ":fungroup END" in the same sourced file? Assume the group ends at the end of the file. Handle nested packages? Alternative: Support packages. {package-name}:{function-name}(). Packages are loaded automatically when first used, from $VIMRUNTIME/packages (or use a search path). 7 Pre-parse or compile Vim scripts into a bytecode. 1. Put the bytecode with the original script, with an ":if has('bytecode')" around it, so that it's only used with a Vim that supports it. Update the code with a command, can be used in an autocommand. 2. Use a ".vic" file (like Python use .pyc). Create it when writing a .vim file. Problem: distribution. 3. Use a cache directory for each user. How to recognize which cached file belongs to a sourced script? 7 Add argument to winwidth() to subtract the space taken by 'foldcolumn', signs and/or 'number'. 6 Add ++ and -- operators? They only work on variables (lvals), how to implement this? 8 Add functions: has(":command") Check if ":command" works. compare function with "ex_ni". E.g. for ":simalt". system() With a List argument. Bypasses the shell, use exec() directly. (Bob Hiestand) escape() Add argument to specify what to escape with. modestack() Instead of just the current mode return the stack of Insert / CTRL-O / :normal things. realname() Get user name (first, last, full) user_fullname() patch by Nikolai Weibull, Nov 3 2002 Only add this when also implemented for non-Unix systems, otherwise a shell cmd could be used. get_user_name() gets login name. menuprop({name}, {idx}, {what}) Get menu property of menu {name} item {idx}. menuprop("", 1, "name") returns "File". menuprop("File", 1, "n") returns "nmenu File.Open..." argument. Patch by Ilya Sher, 2004 Apr 22 Return a list of menus and/or a dictionary with properties instead. mapname({idx}, mode) return the name of the idx'th mapping. Patch by Ilya Sher, 2004 Mar 4. Return a list instead. char2hex() convert char string to hex string. attributes() return file protection flags "drwxrwxrwx" filecopy(from, to) Copy a file shorten(fname) shorten a file name, like home_replace() perl(cmd) call Perl and return string inputrl() like input() but right-to-left virtualmode() add argument to obtain whether "$" was used in Visual block mode. getacp() Win32: get codepage (Glenn Maynard) deletebufline() delete line in any buffer appendbufline() append line in any buffer libcall() Allow more than one argument. libcallext() Like libcall(), but using a callback function to allow the library to execute a command or evaluate an expression. 7 Make bufname("'0") return the buffer name from mark '0. How to get the column and line number? col("'0") currently returns zero. 8 argc() returns 0 when using "vim -t tag". How to detect that no file was specified in any way? To be able to jump to the last edited file. 8 Pass the command line arguments to Vim scripts in some way. As v:args List? Or extra parameter to argv()? 8 Add command arguments with three dashes, passed on to Vim scripts. 7 Add optional arguments to user functions: :func myFunc(arg1, arg2, arg3 = "blah", arg4 = 17) 6 User functions: Functions local to buffer "b:func()"? 8 For Strings add ":let var[{expr}] = {expr}". When past the end of "var" just ignore. 8 The "= register should be writable, if followed by the name of a variable, option or environment variable. 8 ":let &option" should list the value of the option. 8 ":let Func().foo = value" should work, also when "foo" doesn't exist. 7 Add synIDlist(), making the whole list of syntax items on the syntax stack available as a List. 8 Add autocommand-event for when a variable is changed: :au VarChanged {varname} {commands} 8 Add "has("gui_capable")", to check if the GUI can be started. 8 Add possibility to use variables like registers: characterwise (default), linewise (when ending in '\n'), blockwise (when ending in '\001'). reg0, rega, reg%, etc. Add functions linewise({expr}), blockwise({expr}) and charwise({expr}). 7 Make it possible to do any command on a string variable (make a buffer with one line, containing the string). Maybe add an (invisible) scratch buffer for this? result = scratch(string, command) result = apply(string, command) result = execute(string, command) "command" would use <> notation. Does scratch buffer have a number? Or re-use same number? 7 Add function to generate unique number (date in milliseconds). 7 Automatically load a function from a file when it is called. Need an option for the search path. (Sekera) Robustness: 6 Add file locking. Lock a file when starting to edit it with flock() or fcntl(). This patch has advisory file locking while reading/writing the file for Vim 5.4: ~/vim/patches/kahn_file_locking . The patch is incomplete (needs support for more systems, autoconf). Andy doesn't have time to work on it. Disadvantage: Need to find ways to gracefully handle failure to obtain a lock. When to release a lock: When buffer is unloaded? Performance: 7 For strings up to 3 bytes don't allocate memory, use v_list itself as a character array. Use VAR_SSTRING (short string). 8 Instead of loading rgb.txt every time a color wasn't recognized load it once and keep it in memory. Move the code to a common place to avoid repeating it in various system files. 8 Turn b_syn_ic and b_syn_containedin into b_syn_flags. 9 Loading menu.vim still takes quite a bit of time. How to make it faster? 8 in_id_list() takes much time for syntax highlighting. Cache the result? 7 setpcmark() shifts the jumplist, this takes quite a bit of time when jumping around. Instead use an index for the start? 8 When displaying a space with only foreground highlighting, it's the same as a space without attributes. Avoid displaying spaces for the "~" lines when starting up in a color terminal. 8 Avoid alloc() for scratch buffer use, esp. in syntax.c. It's very slow on Win16. 9 Setting GUI options in the console (e.g., 'guifont') should not cause a redraw. 8 Profiling shows that in_id_list() is used very often for C code. Can this function be improved? 8 For an existing file, the page size of the swap file is always the default, instead of using the block size of the device, because the swap file is created only after setting the block size in mf_open(). How can this be improved? 8 Set default for 'ttyscroll' to half a screen height? Should speed up MS-DOS version. (Negri) 7 C syntax highlighting gets a lot slower after ":set foldmethod=syntax". (Charles Campbell) Inserting a "{" is very slow. (dman) 7 HTML syntax highlighting is slow for long lines. Try displaying http://www.theregister.co.uk/content/4/22908.html. (Andre Pang) 7 Check how performance of loading the wordlist can be improved (adding a lot of abbreviations). 7 DOS console: Add t_DL support, to make scrolling faster. 7 Compile Ex commands to byte codes. Store byte codes in a vim script file at the end, after "compiled:. Make it look like a single comment line for old Vim versions. Insert first line "Vim script compiled . Only used compiled code when timestamp matches the file stat. Add command to compile a vim script and add it to the file in-place. Split Ex command executing into a parsing and executing phase. Use compiled code for functions, while loops, etc. 8 When editing a file with extremely long lines (e.g., an executable), the "linerest" in readfile() is allocated twice to be able to copy what was read so far. Use realloc() instead? Or split the line when allocating memory fails and "linerest" is big (> 100000)? 8 When defining autocommands (e.g., from $VIMRUNTIME/filetype.vim), need to compare each pattern with all existing patterns. Use a hash code to avoid using strcmp() too often? 7 Include turbo_loader patches, speeding up reading a file? Speed up reading a file by reading it into a fixed-size buffer, creating the list of indexes in another buffer, and then copying the result into a memfile block with two copies. Then read the next block into another fixed-size buffer, create the second list of indexes and copy text from the two blocks to the memfile block. 7 do_cmdline(): Avoid that the command line is copied to allocated memory and freed again later all the time. For while loops, and for when called with an argument that can be messed with. Generic solution: Make a struct that contains a pointer and a flag that indicates if the pointer should be freed when replaced. 7 Check that the file size is not more than "sizeof(long)". - Further improve finding mappings in maphash[] in vgetorpeek() 8 Syntax highlighting is slow when deleting lines. Try in $VIMRUNTIME/filetype.vim. - "out of memory" after deleting (1,$d) and changing (:%s/^/> /) a lot of lines (27000) a few times. Memory fragmentation? - Have a look at how pdksh does memory allocation (alloc.c). (Dalecki) - Do profiling on: - :g/pat/normal cmd - 1000ii - deleting 10Mbyte worth of lines (netscape binary) - "[i" and "[d" (Yegappan Lakshmanan) - ":g/^/m0" on a 450Kbyte file. And the "u". - highlighting "~/vim/test/longline.tex", "~/vim/test/scwoop.tcl" and "~/vim/test/lockup.pl". - loading a syntax file to highlight all words not from a dictionary. - editing a Vim script with syntax highlighting on (loading vim.vim). 7 Screen updating can be further improved by only redrawing lines that were changed (and lines after them, when syntax highlighting was used, and it changed). - On each change, remember start and end of the change. - When inserting/deleting lines, remember begin, end, and line count. - Use macros/duarte/capicua for profiling. Nvi 1.71 is the fastest! - When using a file with one long line (1Mbyte), then do "$hhhh", is still very slow. Avoid calling getvcol() for each "h"? - Executing a register, e.g. "10000@@" is slow, because ins_typebuf has to move the previous commands forward each time. Pass count from normal_cmd() down to do_execreg(). - Repeating insert "1000i-" displays --INSERT-- all the time, because of the at the end. Make this work faster (disable redrawing). - Avoid calls to plines() for cursor line, use w_cline_height. - After ":set nowrap" remove superfluous redraw with wrong hor. offset if cursor is right of the screen. 8 Make CTRL-C on Unix generate a signal, avoid using select() to check for a CTRL-C (it's slow). Code size: 8 GUI: When NO_CONSOLE is defined, more code can be excluded. - Put getline() and cookie in a struct, so only one argument has to be passed to do_cmdline() and other functions. 8 Make a GUI-only version for Unix? 8 In buf_write _() isn't needed when setting errmsg, do it once when using it. 7 When compiling with a GUI-only version, the code for cterm colors can be left out. 8 When compiled with a GUI-only version, the termcap entries for terminals can be removed. 8 Can the check for libelf in configure.in be removed? Messages: 8 When using ":q" in a changed file, the error says to "add !". Add the command so that beginners understand it: "use :q!". 8 For 'verbose' level 12 prints commands from source'ed files. How to skip lines that aren't executed? Perhaps move the echoing to do_cmdline()? 8 Use 'report' for ":bdel"? (Krishna) To avoid these messages when using a script. - Delete message after new command has been entered and have waited for key. Perhaps after ten seconds? - Make message history available in "msg" variables: msg1, msg2, .. msg9. 8 When reading from stdin allow suppressing the "reading from stdin" message. 9 Check handling of overwriting of messages and delays: Very wrong: errors while redrawing cause endless loop. When switching to another file and screen scrolls because of the long message and return must be typed, don't scroll the screen back before redrawing. 7 Add an option, which is a regexp, that disables warning messages which match that regexp (Tsirkin). 8 When address range is wrong you only get "Invalid range". Be a bit more specific: Negative, beyond last line, reverse range? Include the text. 8 Make it possible to ignore errors for a moment ('errorignore'?). Another option to switch off giving error messages ('errorquiet'?). Also an option not to give any messages ('quiet')? Or ":quiet on", ":quiet off". Careful: For a severe error (out of memory), and when the user starts typing, error messages must be switched back on. Also a flag to ignore error messages for shell commands (for mappings). - Option to set time for emsg() sleep. Interrupt sleep when key is typed? Sleep before second message? 8 In Ex silent mode or when reading commands from a file, what exactly is not printed and what is? Check ":print", ":set all", ":args", ":vers", etc. At least there should be no prompt. (Smulders) And don't clear the screen when reading commands from stdin. (Kendall) --> Make a difference between informative messages, prompts, etc. and error messages, printing text, etc. 8 Window should be redrawn when resizing at the hit-enter prompt. Also at the ":tselect" prompt. Find a generic solution for redrawing when a prompt is present (with a callback function?). Screen updating: 7 Add a string to the 'display' option to make CTRL-E and CTRL-Y scroll one screen line, also if this means the first line doesn't start with the first character (like what happens with a single line that doesn't fit). - screen_line(): - insert/delete character stuff. - improve delete rest of line (spaces at end of line). - When moving or resizing window, try to avoid a complete redraw (esp. when dragging the status line with the mouse). - When 'lazyredraw' set, don't echo :ex commands? Need a flag to redraw when waiting for a character. 8 Add a ":refresh [winnr]" command, to force updating a window. Useful from an event handler where ":normal" can't be used. Also useful when 'lazyredraw' is set in a mapping. 7 Make 'list' and 'linebreak' work together. Scrolling: 8 Add "zm" command: scroll horizontally to put the cursor in the middle. 6 Add option to set the overlap for CTRL-F and CTRL-B. (Garhi) - extend 'scrollbind' option: 'scrollopt' words "search", "relative", etc.. Also 'e'xecute some commands (search, vertical movements) in all bound windows. 7 Add 'scrollbind' feature to make the offset of one window with the next one equal to the window height. When editing one file in both windows it looks like each window displays a page of the buffer. - Allow scrolling by dragging with the mouse (grab a character and move it up/down). Like the "hand" in Acrobat reader. Use Alt-LeftMouse for this? (Goldfarb) - Add command to execute some commands (search, vertical movements) in all bound windows. - Add 'search' option to 'scrollopt' to allow 'scrollbind' windows to be bound by regexp searches - Add "z>" and "z<": scroll sideways one screenful. (Campbell) - Add option to set the number of lines when not to scroll, instead of the fixed number used now (for terminals that scroll slow with a large number of lines but not with a single line). Autoconf: 8 Should use acconfig.h to define prototypes that are used by autoheader. 8 Some compilers don't give an error for "-OPT:Olimit" but a warning. (Webb) Add a check for the warning, so that "Olimit" can be added automatically? - Autoconf: Use @datadir@ for the system independent files. Make sure the system dependent and system independent files are separated. (Leitner). - Add autoconf check for waitpid()/wait4(). - Remove fcntl() from autoconf, all systems have it? - Set default for 'dictionary', add search for dictionary to autoconf. Perl interface: 8 Rename typemap file to something else? 7 Make buffers accessed as Perl arrays. (Clark) 7 Make it possible to compile with non-ANSI C? 6 Tcl/Tk has the "load" command: load a shared library (.so or .dll). Shared libraries: 6 Add support for loading shared libraries, and calling functions in it. :libload internal-name libname :libunload internal-name :liblist :libcall internal-name function(arg1, arg2, ...) :libcall function(arg1, arg2, ...) libcall() can have only one integer or String argument at the moment. 6 Have a look on how Perl handles loading dynamic libraries. Tags: 9 With ":set tags=./tags,../tags" and a tag appears in both tags files it is added twice. Requires figuring out the actual file name for each found match. Remove tag_fname from the match and combine it with the fname in the match (without expanding or other things that take time). When 'tagrelative' is off tag_fname isn't needed at all. 8 Use a mechanism similar to omni completion to figure out the kind of tab for CTRL-] and jump to the appropriate matching tag (if there are several). 7 Can CTRL-] (jump to tag) include a following "." and "->" to restrict the number of possible matches? Check tags file for an item that has members. (Flemming Madsen) 8 Scope arguments for ":tag", e.g.: ":tag class:cPage open", like Elvis. 8 When output of ":tselect" is long, getting the more-prompt, should be able to type the tag number directly. 7 Add the possibility to use the "-t {tag}" argument multiple times. Open a window for each tag. 7 Make output of ":tselect" a bit nicer. Use highlighting? 7 Highlight the "tag 1 of >2" message. New highlight group, or same as "hit bottom" search message. 7 When using ":tag" at the top of the tag stack, should add another entry, so CTRL-T can bring you back to where you are now AND to where you were before the previous ":tag" command. (Webb) - When doing "[^I" or "[^D" add position to tag stack. - Add command to put current position to tag stack: ":tpush". - Add functions to save and restore the tag stack? Or a command to switch to another tag stack? So that you can do something else and come back to what you were working on. 7 When using CTRL-] on someClass::someMethod, separate class from method and use ":ta class:someClass someMethod". Include C++ tags changes (Bertin). Change "class::func" tag into "func" with "class=class"? Docs in oldmail/bertin/in.xxx. 7 Add ":tagargs", to set values for fields: :tagargs class:someclass file:version.c :tagargs clear These are then the default values (changes the order of priority in tag matching). 7 Support for "gtags" and "global"? With ":rtag" command? There is an example for how to do this in Nvi. Or do it like Elvis: 'tagprg' and 'tagprgonce' options. (Yamaguchi) The Elvis method is far more flexible, do it that way. 7 Support "col:99" extra field, to position the cursor in that column. With a flag in 'cpoptions' to switch it off again. 7 Better support for jumping to where a function or variable is used. Use the id-utils, with a connection to "gid" (Emacs can do it too). Add ":idselect", which uses an "ID" database (made by "mkid") like "tsel
