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* + +Most interesting new features to be added when all bugs have been fixed: +- Using ":exe edit fname" has escaping problems. Use ":edit ++(fname)". + Thus use "++=" to give arguments as expressions, comma-separated as if + calling a function. + With options: ":edit ++(['!', '++enc=abc'], ['+/pat'], fname)". + Alternative: Make a function for Ex commands: cmd_edit(). +- Add COLUMN NUMBERS to ":" commands ":line1,line2[col1,col2]cmd". Block + can be selected with CTRL-V. Allow '$' (end of line) for col2. + (issue #3292) +- 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. +- Scroll commands by screen line. g CTRL-E and g CTRL-Y ? Requires the + first line to be able to start halfway. +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) +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 multibyte characters +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 <Tab> to jump to the next tag in || and + <C-Tab> (and <S-Tab>) to the previous tag. + Patch by Balazs Kezes, 2007 Dec 30. Remark from A. Politz. +- 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. +- 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 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 (<F1>) context sensitive? +- Learn mode: show short help while typing commands. + + +User Friendlier: +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 <file>"? +- Add mappings local to a window: ":map <window> ..." #9339 +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 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.) +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. +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. +8 Add local options for each tab page? E.g., 'diffopt' could differ between + tab pages. +7 Add local highlighting for each tab page? + + +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'.

(Evan Laforge, 2009 Oct 17) +- Add ":nofold". Range will apply without expanding to closed fold. +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.

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', they should use "syn iskeyword". + Also need a separate 'iskeyword' for the command line, e.g., in a help + window ":e /asdf/asdf/" CTRL-W works different. +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 When using a cterm, and no ctermfg or ctermbg are defined, use start/stop + sequences.

(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.

(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. +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: + <B> bold text <I> italic+bold text </B> italic text </I> +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. +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.

Should start search for syntax patterns above the + first drawn line. (#8103) +- Syntax priority problem. (Charles Campbell, 2011 Sep 15) +- 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) +- Syntax HL error caused by "containedin". (Peter Hodge, 2006 Oct 6) +- Open two windows on the same C code, delete a ")" in one window, resulting + in highlighted "{" in that window, not in the other. +- When using "nextgroup" and the group has an empty match, there is no + search at that position for another match. (Lukas Mai, 2008 April 11) + + +Vim script language: +8 Make the filename and line number available to script functions, so that + they can give useful debugging info. The whole call stack would be ideal. + At least use this for error messages. +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)? +- 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 Have a prefix for a function to make it unique. When using packages it + can be the plugin name. + Perhaps also have a way to remove everything that the package added? + including autocommands. +7 Pre-parse or compile Vim scripts into a bytecode, like :def functions. + Possibilities: + 1. Put the bytecode with the original script, with an ":if + has('bytecode-1234')" around it, so that it's only used with a Vim that + supports the version. 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, non-writable directory, etc. + 3. Use a cache directory for each user. Disadvantage: cache lookup may + cost more time than bytecode wins. +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". + 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. + crypt() encrypt string + decrypt() decrypt string + base64enc() base 64 encoding + base64dec() base 64 decoding + 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 + typed() return the characters typed and consumed (to + find out what happened) + virtualmode() add argument to obtain whether "$" was used in + Visual block mode. + getacp() Win32: get codepage (Glenn Maynard) + 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. +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. + Also: ":let Func()[foo] = value" should work. Same for a List. +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). + + +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 string variables up to 3 bytes don't allocate memory, use v_list + itself as a character array. Use VAR_SSTRING (short string). +7 Add 'lazysize' option: Above this size Vim doesn't load everything before + starting to edit a file. Things like 'fileencodings' only work up to this + size, modelines only work at the top. Useful for large log files where + you only want to look at the first few pages. Use zero to disable it. +8 move_lines() copies every line into allocated memory, making reloading a + buffer a lot slower than re-editing the file. Can the memline be locked + so that we don't need to make a copy? Or avoid invoking ml_updatechunk(), + that is taking a lot of time. (Ralf Wildenhues, 2008 Jul 7) + With a patch, but does it work? +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. +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 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 <timestamp>. + 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 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 + - 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(). +- 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.ac 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. +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. +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: +- 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. + +Scrolling: +8 Add "zy" 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: +8 libcall() can keep the library around instead of always calling dlclose(). + (Jason Felice, 2018 Mar 20) +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 For 'tags' wildcard in the file name is not supported, only in the path. + This is due to it using |file-searching|. Suboptimal solution would be to + make the filename or the whole option use |wildcards| globing, better + would be to merge the 2 kinds of globing. originally (Erik Falor, 2008 + April 18), updated (Ian Kelling, 2008 July 4) +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 "tselect". + + +Win32 GUI: +8 Make debug mode work while starting up (vim -D). Open console window for + the message and input? +8 When using "Edit with Vim" for one file it changes directory, when several + files are selected and using "Edit with single Vim" the directory isn't + changed. At least change directory when the path is the same for all + files. Perhaps just use the path of the first file or use the longest + common part of the path. +8 Add font argument to set the lfCharSet. (Bobcik) +8 Somehow automatically detect the system language and set $LANG, so that + gettext and menus work. +8 Could keep console open to run multiple commands, to avoid the need to hit + return in every console. + Also: Look at how Emacs does run external commands: + http://www.cs.washington.edu/homes/voelker/ntemacs.html. +8 Need a separate PopUp menu for modeless selection. Need two new commands: + Copy selection to clipboard, Paste selection (as typed text). +8 Support copy/paste for other file formats. At least HTML, perhaps RTF. + Add "copy special" and "paste special" commands? +7 Use different default colors, to match the current Windows color scheme. + Sys_WindowText, Sys_Window, etc. (Lionel Schaffhauser) +7 Use <C-Tab> to cycle through open windows (e.g., the find dialog). +7 <Esc> should close a dialog. +7 Keep the console for external commands open. Don't wait for a key to be + hit. Re-open it when the user has closed it anyway. Or use a prepended + command: ":nowait {cmd}", or ":quiet", which executes {cmd} without any + prompts. +7 Should be able to set an option so that when you double click a file that + is associated with Vim, you can either get a new instance of Vim, or have + the file added into an already running Vim. +7 The "-P" argument only works for the current codepage. Use wide + functions to find the window title. + + +GUI: +7 Implement ":popup" for other systems than Windows. +8 Implement ":tearoff" for other systems than Win32 GUI. +6 Implement ":untearoff": hide a torn-off menu. +8 When using the scrollbar to scroll, don't move the cursor position. When + moving the cursor: scroll to the cursor position. +9 Make <S-Insert> paste from the clipboard by default. (Kunze) +7 Menu local to a buffer, like mappings. Or local to a filetype? +8 In Buffers menu, add a choice whether selecting a buffer opens it in the + current window, splits the window or uses ":hide". +8 Dragging the mouse pointer outside of a Vim Window should make the text + scroll. Return a value from gui_send_mouse_event() to the machine + specific code to indicate the time in which the event should be repeated. +8 Make it possible to ignore a mouse click when it's used to give Vim (gvim) + window focus. Also when a mouse click is used to bring a window to front. +8 Make the split into system independent code and system specific code more + explicit. There are too many #ifdefs in gui.c. + If possible, separate the Vim code completely from the GUI code, to allow + running them in separate processes. +7 X11: Support cursorColor resource and "-cr" argument. +8 X11 (and others): CTRL-; is not different from ';'. Set the modifier mask + to include CTRL for keys where CTRL produces the same ASCII code. +7 Add some code to handle proportional fonts on more systems? Need to draw + each character separately (like xterm). Also for when a double-width font + is not exactly double-width. (Maeda) +8 Should take font from xterm where gvim was started (if no other default). +8 Selecting font names in X11 is difficult, make a script or something to + select one. +8 Visual highlighting should keep the same font (bold, italic, etc.). +8 Add flag to 'guioptions' to not put anything in the clipboard at all? +8 Should support a way to use keys that we don't recognize yet. Add a + command that adds entries to special_keys somehow. How do we make this + portable (X11, Win32, ..)? +7 Add a flag to 'guioptions' that tells not to remove inactive menu items. + For systems where greying-out or removing menu items is very slow. The + menu items would remain visibly normally, but not do anything. +7 Add ":minimize" and ":maximize", which iconize the window and back. + Useful when using gvim to run a script (e.g. 2html.vim). +7 X11: Is it possible to free allocated colors, so that other programs can + use them again? Otherwise, allow disabling allocating the default colors. + Or allocate an own colormap (check UAE). With an option to use it. For + the commandline, "-install" is mostly used for X11 programs. +7 Should support multi-column menus. +- Should add option for where to put the "Help" menu: like Motif at the far + right, or with the other menus (but still at the right). +- Add menu item to "Keep Insert mode". +8 ":mkgvimrc" command, that includes menus. +6 Big change: Move GUI to separate program "vimgui", to make startup of vim a + lot faster, but still be able to do "vim -g" or ":gui". +7 More explicit mouse button binding instead of 'mousemodel'? +7 Add option to set the position of the window on the screen. 'windowpos', + which has a value of "123,456": <x>,<y>. + Or add a command, like ":winsize"? +7 Add toolbar for more GUIs. +8 Make it possible to use "amenu icon=BuiltIn##", so that the toolbar item + name can be chosen free. +7 Make it possible to put the toolbar on top, left, right and/or bottom of + the window? Allows for softkey-like use. +6 Separate the part of Vim that does the editing from the part that runs the + GUI. Communicate through a pseudo-tty. Vim starts up, creates a + pty that is connected to the terminal. When the GUI starts, the pty is + reconnected to the GUI process. When the GUI stops, it is connected to + the terminal again. Also use the pty for external processes, it looks + like a vt100 terminal to them. Vim uses extra commands to communicate GUI + things. +7 Motif: For a confirm() dialog <Enter> should be ignored when no default + button selected, <Esc> should close the dialog. +7 When using a pseudo-tty Vim should behave like some terminal (vt52 looks + simple enough). Terminal codes to/from shell should be translated. +- Would it be useful to be able to quit the GUI and go back to the terminal + where it was started from? +7 Support "-visual <type>" command line argument. + + +Autocommands: +9 Add WinNewPre - before creating a new window. #10635 +9 When triggering WinNew provide the window ID somehow. #10633 +9 Rework the code from FEAT_OSFILETYPE for autocmd-osfiletypes to use + 'filetype'. Only for when the current buffer is known. +- Put autocommand event names in a hashtable for faster lookup? +8 When the SwapExists event is triggered, provide information about the + swap file, e.g., whether the process is running, file was modified, etc. + Must be possible to check the situation that it's probably OK to delete + the swap file. (Marc Merlin) +8 When all the patterns for an event are "*" there is no need to expand + buffer names to a full path. This can be slow for NFS. +7 For autocommand events that trigger multiple times per buffer (e.g., + CursorHold), go through the list once and cache the result for a specific + buffer. Invalidate the cache when adding/deleting autocommands or + changing the buffer name. +7 Add TagJump event: do something after jumping to a tag. +8 Add "TagJumpFile" autocommand: When jumping to another file for a tag. + Can be used to open "main.c.gz" when "main.c" isn't found. +8 Use another option than 'updatetime' for the CursorHold event. The two + things are unrelated for the user (but the implementation is more + difficult). +7 Add autocommand event for when a buffer cannot be abandoned. So that the + user can define the action taking (autowrite, dialog, fail) based on the + kind of file. (Yakov Lerner) Or is BufLeave sufficient? +8 Autocommand for when modified files have been found, when getting input + focus again (e.g., FileChangedFocus). + Check when: getting focus, jumping to another buffer, ... +8 Autocommands should not change registers. And marks? And the jumplist? + And anything else? Add a command to save and restore these things. +8 Add autocommands, user functions and user commands to ":mkvimrc". +6 Add KeymapChanged event, so that the effects of a different keymap can be + handled (e.g., other font) (Ron Aaron) +7 When trying to open a directory, trigger an OpenDirectory event. +7 Add file type in front of file pattern: <d> for directory, <l> for link, + <x> for executable, etc. With commas to separate alternatives. The + autocommand is only executed when both the file type AND the file pattern + match. (Leonard) +5 Add option that specifies extensions which are to be discarded from the + file name. E.g. 'ausuffix', with ".gz,.orig". Such that file.c.gz will + trigger the "*.c" autocommands. (Belabas) +7 Add something to break the autocommands for the current event, and for + what follows. Useful for a "BufWritePre" that wants to avoid writing the + file. +8 When editing "tt.gz", which is in DOS format, 'fileformat' stays at + "unix", thus writing the file changes it. Somehow detect that the read + command used dos fileformat. Same for 'fileencoding'. +- Add events to autocommands: + Error - When an error happens + VimLeaveCheck - Before Vim decides to exit, so that it can be cancelled + when exiting isn't a good idea. + CursorHoldC - CursorHold while command-line editing + WinMoved - when windows have been moved around, e.g, ":wincmd J" + SearchPost - After doing a search command (e.g. to do "M") + ShutDown - when the system is about to shut down + InsertCharPost - user typed a character in Insert mode, after inserting + the char. + BufModified - When a buffer becomes modified, or unmodified (for + putting a [+] in the window title or checking out the + file from CVS). + BufFirstChange - When making a change, when 'modified' is set.

Thus "abb ab xxx" and typing "ab<Space>" inserts "xxx" and + not the <Space>. +8 Give a warning when using CTRL-C in the lhs of a mapping. It will never + (?) work. +7 Add <0x8f> (hex), <0o33> (octal) and <123> (decimal) to <> notation? +7 When someone tries to unmap with a trailing space, and it fails, try + unmapping without the trailing space. Helps for ":unmap xx | unmap yy". +6 Context-sensitive abbreviations: Specify syntax group(s) in which the + abbreviations are to be used. +- Add mappings that take arguments.

Also: Repeat a whole insert command, including any mappings + that it included. Sort-of automatic recording? +- Include an option (or flag to 'cpoptions') that makes errors in mappings + not flush the rest of the mapping (like nvi does). +- Use context sensitiveness of completion to switch abbreviations and + mappings off for :unab and :unmap. +6 When using mappings in Insert mode, insert characters for incomplete + mappings first, then remove them again when a mapping matches. Avoids + that characters that are the start of some mapping are not shown until you + hit another character. +- Add mappings for replace mode: ":rmap". How do we then enter mappings for + non-replace Insert mode? +- Add separate mappings for Visual-character/block/line mode? +- Add 'mapstop' command, to stop recursive mappings. +- List mappings that have a raw escape sequence both with the name of the key + for that escape sequence (if there is one) and the sequence itself. +- List mappings: Once with special keys listed as <>, once with meta chars as + <M-a>, once with the byte values (octal?). Sort of "spell mapping" command? +- When entering mappings: Add the possibility to enter meta keys like they + are displayed, within <>: <M-a>, <~@> or <|a>. +- Allow multiple arguments to :unmap. +- Command to show keys that are not used and available for mapping + ":freekeys". +- Allow any character except white space in abbreviations lhs (Riehm). + + +Incsearch: +- Wrong scrolling when using incsearch.

Where to show the + number? +7 Support for approximate-regexps to find similar words (agrep + http://www.tgries.de/agrep/ tre: http://laurikari.net/tre/index.html). +8 Add an item for a big character range, so that one can search for a + chinese character: \z[234-1234] or \z[XX-YY] or \z[0x23-0x234]. +7 Add an item stack to allow matching (). One side is "push X on + the stack if previous atom matched". Other side is "match with top of + stack, pop it when it matches". Use "\@pX" and "\@m"? + Example: \((\@p).\{-}\@m\)* +7 Add a flag to "/pat/" to discard an error. Useful to continue a mapping + when a search fails. Could be "/pat/E" (e is already used for end offset). +7 Add pattern item to use properties of Unicode characters. In Perl it's + "\p{L}" for a letter. See Regular Expression Pocket Reference. +8 Would it be possible to allow ":23,45/pat/flags" to search for "pat" in + lines 23 to 45? Or does this conflict with Ex range syntax? +8 Allow identical pairs in 'matchpairs'. Restrict the search to the current + line. +7 Allow longer pairs in 'matchpairs'.

(Margo) Maybe make it accessible through a register (like "/ + for search string)? +7 Use T-search algorithm, to speed up searching for strings without special + characters. See C't article, August 1997. +- Add 'fuzzycase' option, so that case doesn't matter, and '-' and '_' are + equivalent (for Unix filenames). +- Add 'v' flag to search command: enter Visual mode, with the matching text + as Visual area. (variation on idea from Bertin) +- Searching: "/this//that/" should find "that" after "this". +- Add global search commands: Instead of wrapping at the end of the buffer, + they continue in another buffer. Use flag after search pattern: + a for the next file in the argument list + f for file in the buffer list + w for file edited in a window. + e.g. "/pat/f". Then "n" and "N" work through files too. "f" flag also for + ":s/pat/foo/f"??? Then when 'autowrite' and 'hidden' are both not set, ask + before saving files: "Save modified buffer "/path/file"? (Yes/Hide/No + Save-all/hide-All/Quit) ". +- ":s/pat/foo/3": find 3rd match of "pat", like sed. (Thomas Koehler) +7 When searching with 'n' give message when getting back where the search + first started. Remember start of search in '/ mark. +7 Add option that scrolls screen to put cursor in middle of screen after + search always/when off-screen/never. And after a ":tag" command. Maybe + specify how many lines below the screen causes a redraw with the cursor in + the middle (default would be half a screen, zero means always). +6 Support multiple search buffers, so macros can be made without side + effects. +7 From xvim: Allow a newline in search patterns (also for :s, can delete + newline). Add BOW, EOW, NEWL, NLORANY, NLBUTANY, magic 'n' and 'r', etc. + [not in xvim:] Add option to switch on matches crossing ONE line boundary. +7 Add ":iselect", a combination of ":ilist" and ":tselect".

Use {line}.{column} notation in an Ex + range, e.g.: ":1.3,$.5s" means to substitute from line 1 column 3 to the + last line column 5. +5 Add commands to bookmark lines, display bookmarks, remove bookmarks, + operate on lines with bookmarks, etc. Like ":global" but with the + possibility to keep the bookmarks and use them with several commands. + (Stanislav Sitar) + + +Mouse support: +8 Add 'o' flag to 'mouse'? +7 Be able to set a 'mouseshape' for the popup menu. +8 Add 'mouse' flag, which sets a behavior like Visual mode, but automatic + yanking at the button-up event. Or like Select mode, but typing gets you + out of Select mode, instead of replacing the text. (Bhaskar) +- Implement mouse support for the Amiga console. +- Using right mouse button to extend a blockwise selection should attach to + the nearest corner of the rectangle (four possible corners). +- Precede mouse click by a number to simulate double clicks?!? +- When mouse click after 'r' command, get character that was pointed to. + + +Argument list: +6 Add command to put all filenames from the tag files in the argument list. + When given an argument, only use the files where that argument matches + (like `grep -l ident`) and jump to the first match. +6 Add command to form an args list from all the buffers? + + +Registers: +8 Don't display empty registers with ":display". (Etienne) +8 Add put command that overwrites existing text. Should also work for + blocks. Useful to move text around in a table. Works like using "R ^R r" + for every line. +- When appending to a register, also report the total resulting number of + lines. Or just say "99 more lines yanked", add the "more". +- When inserting a register in Insert mode with CTRL-R, don't insert comment + leader when line wraps? +- The ":@r" commands should take a range and execute the register for each + line in the range. +- Add "P" command to insert contents of unnamed register, move selected text + to position of previous deleted (to swap foo and bar in " + foo") +8 Should be able to yank and delete into the "/ register. + How to take care of the flags (offset, magic)? +- In Select mode the deleted text always goes into the unnamed register. + Use CTRL-R to specify the register to use. (#9531) +- When "+ register is set then "" points to it. If another Vim grabs the "+ + register, then "" doesn't contain anything. Make it still follow "+. + (#6435) +- Pasting a register in Visual mode cannot be repeated. (Mahmoud Al-Qudsi, + 2018 Apr 26, #2849) +- Patch to add option that tells whether small deletes go into the numbered + registers. (Aryeh Leib Taurog, 2013 Nov 18) +- With "unamedplus" in 'clipboard' pasting in Visual mode causes error for + empty register. (Michael Seiwald, 2011 Jun 28) I can't reproduce it. +- Consider making YankRing or something else that keeps a list of yanked + text part of standard Vim. The "1 to "9 registers are not sufficient. +6 When yanking into the unnamed registers several times, somehow make the + previous contents also available (like it's done for deleting). What + register names to use? g"1, g"2, etc.? + Also do this for the small delete register "-. + + +Debug mode: +8 Add breakpoints for setting an option +8 Add breakpoints for assigning to a variable. +7 Store the history from debug mode in viminfo. +7 Make the debug mode history available with histget() et al. +- In debug mode, using CTRL-R = to evaluate a function causes stepping + through the function. (Hari Krishna Dara, 2006 Jun 28) + + +Various improvements: +7 Add plugins for formatting? Should be able to make a choice depending on + the language of a file (English/Korean/Japanese/etc.). + Setting the 'langformat' option to "chinese" would load the + "format/chinese.vim" plugin. + The plugin would set 'formatexpr' and define the function being called. + Edward L. Fox explains how it should be done for most Asian languages. + (2005 Nov 24) + Alternative: patch for utf-8 line breaking. (Yongwei Wu, 2008 Feb 23) +7 [t to move to previous xml/html tag (like "vatov"), ]t to move to next + ("vatv"). +7 [< to move to previous xml/html tag, e.g., previous <li>. ]< to move to + next <li>, ]< to next </li>, [< to previous </li>. +8 Add ":rename" command: rename the file of the current buffer and rename + the buffer. Buffer may be modified. +7 Instead of filtering errors with a shell script it should be possible to + do this with Vim script. A function that filters the raw text that comes + from the 'makeprg'? +- Add %b to 'errorformat': buffer number. (Yegappan Lakshmanan / Suresh + Govindachar) +7 Allow a window not to have a statusline. Makes it possible to use a + window as a buffer-tab selection. +8 Allow non-active windows to have a different statusline. (Yakov Lerner) +7 Add an invisible buffer which can be edited. For use in scripts that want + to manipulate text without changing the window layout. +8 Add a command to revert to the saved version of file; undo or redo until + all changes are gone. +6 "vim -q -" should read the list of errors from stdin. (Gautam Mudunuri) +8 Add "--remote-fail": When contacting the server fails, exit Vim. + Add "--remote-self": When contacting the server fails, do it in this Vim. + Overrules the default of "--remote-send" to fail and "--remote" to do it + in this Vim. +8 When Vim was started without a server, make it possible to start one, as + if the "--servername" argument was given. ":startserver <name>"? +8 No address range can be used before the command modifiers. This makes + them difficult to use in a menu for Visual mode. Accept the range and + have it apply to the following command. +8 Add the possibility to set 'fileformats' to force a format and strip other + CR characters. For example, for "dos" files remove CR characters at the + end of the line, so that a file with mixed line endings is cleaned up. + To just not display the CR characters: Add a flag to 'display'? +7 Some compilers give error messages in which the file name does not have a + path. Be able to specify that 'path' is used for these files. +7 Xterm sends <Esc>O3F for <M-End>. Similarly for other <M-Home>, <M-Left>, + etc. Combinations of Alt, Ctrl and Shift are also possible. Recognize + these to avoid inserting the raw byte sequence, handle like the key + without modifier (unless mapped). +6 Add "gG": like what "gj" is to "j": go to the N'th window line. +8 Add command like ":normal" that accepts <Key> notation like ":map". +9 Support ACLs on more systems. +7 Add ModeMsgVisual, ModeMsgInsert, etc. so that each mode message can be + highlighted differently. +7 Add a message area for the user. Set some option to reserve space (above + the command line?). Use an ":echouser" command to display the message + (truncated to fit in the space). +7 Add %s to 'keywordprg': replace with word under the cursor. (Zellner) +8 Support printing on Unix. Can use "lpansi.c" as an example. (Bookout) +8 Add put command that replaces the text under it. Esp. for blockwise + Visual mode. +7 Enhance termresponse stuff: Add t_CV(?): pattern of term response, use + regexp: "\e\[[>?][0-9;]*c", but only check just after sending t_RV. +7 Add "g|" command: move to N'th column from the left margin (after wrapping + and applying 'leftcol'). Works as "|" like what "g0" is to "0". +7 Support setting 'equalprg' to a user function name. +7 Highlight the characters after the end-of-line differently. +7 When 'whichwrap' contains "l", "$dl" should join lines? +8 Add an argument to configure to use $CFLAGS and not modify it? (Mooney) +8 Enabling features is a mix of configure arguments and defines in + feature.h. How to make this consistent? Feature.h is required for + non-unix systems. Perhaps let configure define CONF_XXX, and use #ifdef + CONF_XXX in feature.h? Then what should min-features and max-features do? +8 Add "g^E" and "g^Y", to scroll a screen-full line up and down. +8 Add ":confirm" handling in open_exfile(), for when file already exists. +8 When quitting with changed files, make the dialog list the changed file + and allow "write all", "discard all", "write some". The last one would + then ask "write" or "discard" for each changed file. Patch in HierAssist + does something like this. (Shah) +7 Use growarray for replace stack. +7 Have a look at viH (Hellenic or Greek version of Vim). But a solution + outside of Vim might be satisfactory (Haritsis). +3 Make "2d%" work like "d%d%" instead of "d2%"? +7 "g CTRL-O" jumps back to last used buffer. Skip CTRL-O jumps in the same + buffer. Make jumplist remember the last ten accessed buffers? +7 Make it possible to set the size of the jumplist (also to a smaller number + than the default). (Nikolai Weibull) +- Add code to disable the CAPS key when going from Insert to Normal mode. +- Set date/protection/etc. of the patchfile the same as the original file. +- Use growarray for termcodes[] in term.c +- Add <window-99>, like <cword> but use filename of 99'th window. +7 Add a way to change an operator to always work characterwise-inclusive + (like "v" makes the operator characterwise-exclusive). "x" could be used. +- Make a set of operations on list of names: expand wildcards, replace home + dir, append a string, delete a string, etc. +- Remove using mktemp() and use tmpname() only? Ctags does this. +- When replacing environment variables, and there is one that is not set, + turn it into an empty string? Only when expanding options? (Hiebert) +- Option to set command to be executed instead of producing a beep (e.g. to + call "play newbeep.au"). +- Add option to show the current function name in the status line. More or + less what you find with "[[k", like how 'cindent' recognizes a function. + (Bhatt). +- "[r" and "]r": like "p" and "P", but replace instead of insert (esp. for + blockwise registers). +- Add 'timecheck' option, on by default. Makes it possible to switch off the + timestamp warning and question. (Dodt). +- Add an option to set the time after which Vim should check the timestamps + of the files. Only check when an event occurs (e.g., character typed, + mouse moved). Useful for non-GUI versions where keyboard focus isn't + noticeable. +- Make 'smartcase' work even though 'ic' isn't set (Webb). +7 When formatting text, allow to break the line at a number of characters. + Use an option for this: 'breakchars'? Useful for formatting Fortran code. +- Add flag to 'formatoptions' to be able to format book-style paragraphs + (first line of paragraph has larger indent, no empty lines between + paragraphs). Complements the '2' flag. Use '>' flag when larger indent + starts a new paragraph, use '<' flag when smaller indent starts a new + paragraph. Both start a new paragraph on any indent change. +8 The 'a' flag in 'formatoptions' is too dangerous. In some way only do + auto-formatting in specific regions, e.g. defined by syntax highlighting. +8 Allow using a trailing space to signal a paragraph that continues on the + next line (MIME text/plain; format=flowed, RFC 2646). Can be used for + continuous formatting. Could use 'autoformat' option, which specifies a + regexp which triggers auto-formatting (for one line). + ":set autoformat=\\s$". +- Be able to redefine where a sentence stops. Use a regexp pattern? +- Support multibyte characters for sentences. Example from Ben Peterson. +7 Add command "g)" to go to the end of a sentence, "g(" to go back to the + end of a sentence. (Servatius Brandt) +- Be able to redefine where a paragraph starts. For "[[" where the '{' is + not in column 1. +6 Add ":cdprev": go back to the previous directory. Need to remember a + stack of previous directories. We also need ":cdnext". +7 Should ":cd" for MS-DOS go to $HOME, when it's defined? +- Make "gq<CR>" work on the last line in the file. Maybe for every operator? +- Add more redirecting of Ex commands: + :redir #> bufname + :redir #>> bufname (append) +- Give error message when starting :redir: twice or using END when no + redirection was active. +- Setting of options, specifically for a buffer or window, with + ":set window.option" or ":set buffer.option=val". Or use ":buffer.set". + Also: "buffer.map <F1> quit". +6 Would it be possible to change the color of the cursor in the Win32 + console? (Klaus Hast) +- Add :delcr command: + *:delcr* + :[range]delcr[!] Check [range] lines (default: whole buffer) for lines + ending in <CR>. If all lines end in <CR>, or [!] is + used, remove the <CR> at the end of lines in [range]. + A CTRL-Z at the end of the file is removed. If + [range] is omitted, or it is the whole file, and all + lines end in <CR> 'textmode' is set. +- Should integrate addstar() and file_pat_to_reg_pat(). +- When working over a serial line with 7 bit characters, remove meta + characters from 'isprint'. +- Use fchdir() in init_homedir(), like in FullName(). +- In win_update(), when the GUI is active, always use the scrolling area. + Avoid that the last status line is deleted and needs to be redrawn. +- That "cTx" fails when the cursor is just after 'x' is Vi compatible, but + may not be what you expect. Add a flag in 'cpoptions' for this? More + general: Add an option to allow "c" to work with a null motion. +- Give better error messages by using errno (strerror()). +- Give "Usage:" error message when command used with wrong arguments (like + Nvi). +- Make 'restorescreen' option also work for xterm (and others), replaces the + SAVE_XTERM_SCREEN define. +7 Support for ":winpos" In xterm: report the current window position. +- Give warning message when using ":set t_xx=asdf" for a termcap code that + Vim doesn't know about. Add flag in 'shortmess'? +6 Add ":che <file>", list all the include paths which lead to this file. +- For a commandline that has several commands (:s, :d, etc.) summarize the + changes all together instead of for each command (e.g. for the rot13 + macro). +- Add command like "[I" that also shows the tree of included files. +- ":set sm^L" results in ":set s", because short names of options are also + expanded. Is there a better way to do this? +- Add ":@!" command, to ":@" like what ":source!" is to ":source". +8 Add ":@:!": repeat last command with forceit set. +- Add 't_normal': Used whenever t_me, t_se, t_ue or t_Zr is empty. +- ":cab map test ^V| je", ":cunab map" doesn't work. This is vi compatible! +- CTRL-W CTRL-E and CTRL-W CTRL-Y should move the current window up or down + if it is not the first or last window. +- Include-file-search commands should look in the loaded buffer of a file (if + there is one) instead of the file itself. +7 Change 'nrformats' to include the leader for each format. Example: + nrformats=hex:$,binary:b,octal:0 + Add setting of 'nrformats' to syntax files. +- 'path' can become very long, don't use NameBuff for expansion. +- When unhiding a hidden buffer, put the same line at top of the window as + the one before hiding it. Or: keep the same relative cursor position (so + many percent down the windows). +- Make it possible for the 'showbreak' to be displayed at the end of the + line. Use a comma to separate the part at the end and the start of the + line? #754 Highlight the linebreak characters, add flag in 'highlight'. + Make 'showbreak' local to a window. +- Some string options should be expanded if they have wildcards, e.g. + 'dictionary' when it is "*.h". +- Use a specific type for number and boolean options, making it possible to + change it for specific machines (e.g. when a long is 64 bit). +- Add option for <Insert> in replace mode going to normal mode. (Nugent) +- Add a next/previous possibility to "[^I" and friends. +- Add possibility to change the HOME directory. Use the directory from the + passwd file? (Antwerpen) +8 Add commands to push and pop all or individual options. ":setpush tw", + ":setpop tw", ":setpush all". Maybe pushing/popping all options is + sufficient. ":setflush" resets the option stack? + How to handle an aborted mapping? Remember position in tag stack when + mapping starts, restore it when an error aborts the mapping? +- Change ":fixdel" into option 'fixdel', t_del will be adjusted each time + t_bs is set? (Webb) +- "gc": goto character, move absolute character positions forward, also + counting newlines. "gC" goes backwards (Weigert). +- When doing CTRL-^, redraw buffer with the same topline. (Demirel) Store + cursor row and window height to redraw cursor at same percentage of window + (Webb). +- Besides remembering the last used line number of a file, also remember the + column. Use it with CTRL-^ et. al. +- Check for non-digits when setting a number option (careful when entering + hex codes like 0xff). +- Add option to make "." redo the "@r" command, instead of the last command + executed by it. Also to make "." redo the whole mapping. Basically: redo + the last TYPED command. +- Support URL links for ^X^F in Insert mode, like for "gf". +- Support %name% expansion for "gf" on Windows. +- Make "gf" work on "file://c:/path/name". "file:/c:/" and "file:///c:/" + should also work? +- Add 'urlpath', used like 'path' for when "gf" used on a URL? +8 When using "gf" on an absolute file name, while editing a remote file + (starts with scp:// or http://) should prepend the method and machine + name. +- When finding a URL or file name, and it doesn't exist, try removing a + trailing '.'. +- Add ":path" command modifier. Should work for every command that takes a + file name argument, to search for the file name in 'path'. Use + find_file_in_path(). +- Highlight control characters on the screen: Shows the difference between + CTRL-X and "^" followed by "X" (Colon). +- Integrate parsing of cmdline command and parsing for expansion. +- Create a program that can translate a .swp file from any machine into a + form usable by Vim on the current machine. +- Add ":noro" command: Reset 'ro' flag for all buffers, except ones that have + a readonly file. ":noro!" will reset all 'ro' flags. +- Add a variant of CTRL-V that stops interpretation of more than one + character. For entering mappings on the command line where a key contains + several special characters, e.g. a trailing newline. +- Make '2' option in 'formatoptions' also work inside comments. +- Add 's' flag to 'formatoptions': Do not break when inside a string. (Dodt) +- When window size changed (with the mouse) and made too small, set it back + to the minimal size. +- Add "]>" and "[<", shift comment at end of line (command; /* comment */). +- Should not call cursorcmd() for each vgetc() in getcmdline(). +- ":split file1 file2" adds two more windows (Webb). +- Don't give message "Incomplete last line" when editing binary file. +- Add ":a", ":i" for preloading of named buffers. +- When entering text, keep other windows on same buffer updated (when a line + entered)? +- Check out how screen does output optimizing. Apparently this is possible + as an output filter. +- In dosub() regexec is called twice for the same line. Try to avoid this. +- Window updating from memline.c: insert/delete/replace line. +- Optimize ml_append() for speed, esp. for reading a file. +- V..c should keep indent when 'ai' is set, just like [count]cc. +- Updatescript() can be done faster with a string instead of a char. +- Screen updating is inefficient with CTRL-F and CTRL-B when there are long + lines. +- Uppercase characters in Ex commands can be made lowercase? +8 Add option to show characters in text not as "|A" but as decimal ("^129"), + hex ("\x81") or octal ("\201") or meta (M-x). Nvi has the 'octal' option + to switch from hex to octal. Vile can show unprintable characters in hex + or in octal. +7 Tighter integration with xxd to edit binary files. Make it more + easy/obvious to use. Command line argument? +- How does vi detect whether a filter has messed up the screen? Check source. + After ":w !command" a wait_return? +- Improve screen updating code for doput() (use s_ins()). +- With 'p' command on last line: scroll screen up (also for terminals without + insert line command). +- Use insert/delete char when terminal supports it. +- Optimize screen redraw for slow terminals. +- Optimize "dw" for long row of spaces (say, 30000). +- Add "-d null" for editing from a script file without displaying. +- In Insert mode: Remember the characters that were removed with backspace + and re-insert them one at a time with <key1>, all together with <key2>. +- Amiga: Add possibility to set a keymap. The code in amiga.c does not work + yet. +- Implement 'redraw' option. +- Add special code to 'sections' option to define something else but '{' or + '}' as the start of a section (e.g. one shiftwidth to the right). +7 Allow using Vim in a pipe: "ls | vim -u xxx.vim - | yyy". Only needs + implementing ":w" to stdout in the buffer that was read from stdin. + Perhaps writing to stdout will work, since stderr is used for the terminal + I/O. +8 Allow opening an unnamed buffer with ":e !cmd" and ":sp !cmd". Vile can + do it. +- Add commands like ]] and [[ that do not include the line jumped to. +- When :unab without matching "from" part and several matching "to" parts, + delete the entry that was used last, instead of the first in the list. +- Add text justification option. +- Set boolean options on/off with ":set paste=off", ":set paste=on". +- After "inv"ing an option show the value: ":set invpaste" gives "paste is + off". +- Check handling of CTRL-V and '\' for ":" commands that do not have TRLBAR. +- When a file cannot be opened but does exist, give error message. +- Amiga: When 'r' protection bit is not set, file can still be opened but + gives read errors. Check protection before opening. +- When writing check for file exists but no permission, "Permission denied". +- If file does not exist, check if directory exists. +- Settings edit mode: make file with ":set opt=xx", edit it, parse it as ex + commands. +- ":set -w all": list one option per line. +- Amiga: test for 'w' flag when reading a file. +- :table command (Webb) +- Add new operator: clear, make area white (replace with spaces): "g ". +- Add command to ":read" a file at a certain column (blockwise read?). +- Add sort of replace mode where case is taken from the old text (Goldfarb). +- Allow multiple arguments for ":read", read all the files. +- Support for tabs in specific columns: ":set tabcol=8,20,34,56" (Demirel). +- Add 'searchdir' option: Directories to search for file name being edited + (Demirel). +- Modifier for the put command: Change to linewise, charwise, blockwise, etc. +- Add commands for saving and restoring options ":set save" "set restore", + for use in macro's and the like. +- Keep output from listings in a window, so you can have a look at it while + working in another window. Put cmdline in a separate window? +- Add possibility to put output of Ex commands in a buffer or file, e.g. for + ":set all". ":r :set all"? +- When the 'equalalways' option is set, creating a new window should not + result in windows to become bigger. Deleting a window should not result in + a window to become smaller (Webb). +- When resizing the whole Vim window, the windows inside should be resized + proportionally (Webb). +- Include options directly in option table, no indirect pointers. Use + mkopttab to make option table? +- When doing ":w dir", where "dir" is a directory name, write the current + file into that directory, with the current file name (without the path)? +- Support for 'dictionary's that are sorted, makes access a lot faster + (Haritsis). +- Add "^Vrx" on the command line, replace with contents of register x. Used + instead of CTRL-R to make repeating possible. (Marinichev) +- Add "^Vb" on the command line, replace with word before or under the + cursor? +- Support mapping for replace mode and "r" command (Vi doesn't do this)? +8 Sorting of filenames for completion is wrong on systems that ignore + case of filenames. Add 'ignorefncase' option. When set, case in + filenames is ignored for sorting them. Patch by Mike Williams: + ~/vim/patches/ignorefncase. Also change what matches? Or use another + option name. +8 Should be able to compile Vim in another directory, with $(srcdir) set to + where the sources are. Add $(srcdir) in the Makefile in a lot of places. + (Netherton) +6 Make it configurable when "J" inserts a space or not. Should not add a + space after "(", for example. +5 When inserting spaces after the end-of-line for 'virtualedit', use tabs + when the user wants this (e.g., add a "tab" field to 'virtualedit'). + (Servatius Brandt) + + +From Elvis: +- Use "instman.sh" to install manpages? +- Add ":alias" command. +- Search patterns: + \@ match word under cursor. + but do: + \@w match the word under the cursor? + \@W match the WORD under the cursor? +8 ":window" command: + :win + next window (up) + :win ++ idem, wrapping + :win - previous window (down) + :win -- idem, wrapping + :win nr to window number "nr" + :win name to window editing buffer "name" +7 ":cc" compiles a single file (default: current one). 'ccprg' option is + program to use with ":cc". Use ":compile" instead of ":cc"? + + +From xvi: +- CTRL-_ : swap 8th bit of character. +- Add egrep-like regex type, like xvi (Ned Konz) or Perl (Emmanuel Mogenet) + + +From vile: +- When horizontal scrolling, use '>' for lines continuing right of a window. +- Support putting .swp files in /tmp: Command in rc.local to move .swp files + from /tmp to some directory before deleting files. + + +Far future and "big" extensions: +- Instead of using a Makefile and autoconf, use a simple shell script to + find the C compiler and do everything with C code. Translate something + like an Aap recipe and configure.ac to C. Avoids depending on Python, + thus will work everywhere. With batch file to find the C compiler it + would also work on MS-Windows. +- Make it easy to setup Vim for groups of users: novice vi users, novice + Vim users, C programmers, xterm users, GUI users,... +- Change layout of blocks in swap file: Text at the start, with '\n' in + between lines (just load the file without changes, except for Mac). + Indexes for lines are from the end of the block backwards. It's the + current layout mirrored. +- Make it possible to edit a register, in a window, like a buffer. +- Add stuff to syntax highlighting to change the text (upper-case keywords, + set indent, define other highlighting, etc.). +- Mode to keep C-code formatted all the time (sort of on-line indent). +- Several top-level windows in one Vim session. Be able to use a different + font in each top-level window. +- Allow editing above start and below end of buffer (flag in 'virtualedit'). +- Smart cut/paste: recognize words and adjust spaces before/after them. +- Add open mode, use it when terminal has no cursor positioning. +- Special "drawing mode": a line is drawn where the cursor is moved to. + Backspace deletes along the line (from jvim). +- Support for underlining (underscore-BS-char), bold (char-BS-char) and other + standout modes switched on/off with , 'overstrike' option (Reiter). +- Add vertical mode (Paul Jury, Demirel): "5vdw" deletes a word in five + lines, "3vitextESC" will insert "text" in three lines, etc.. +4 Recognize l, #, p as 'flags' to EX commands: + :g/RE/#l shall print lines with line numbers and in list format. + :g/RE/dp shall print lines that are deleted. + POSIX: Commands where flags shall apply to all lines written: list, + number, open, print, substitute, visual, &, z. For other commands, flags + shall apply to the current line after the command completes. Examples: + :7,10j #l Join the lines 7-10 and print the result in list +- Allow two or more users to edit the same file at the same time. Changes + are reflected in each Vim immediately.
