MSYS在windows下模拟了一个类unix的终端

Help:
8	When a help window is closed, delete the help buffer from the buffer list?
-	First try using the ":help" argument literally, before using it as a
	pattern.  And then match it as part of a tag.
-	Use GNU Texinfo for the help files somehow?  Use Info format files?
	At least the other way around: Use Vim to view (and edit) .info files.
-	Default mapping for help files: <Tab> to position cursor on next |:tag|.
-	When hitting <Esc> or CTRL-C in Normal mode, give a message to help novice
	users to get out: "Type  :q!  to quit Vim".
-	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.
-	When entering the help window, don't resize to 'helpheight' if the user has
	reduced the size before (Webb). Keep the window height that the user set
	the window to in a "preferred window height" entry for each window.
-	":help :s^I" should expand to ":help :substitute".
-	Make the help key (<F1>) context sensitive?
-	Learn mode: show short help while typing commands.


"make test":
-	Find a way to skip tests that can't be done.  For non-Unix systems, but
	also for e.g. the Perl interface.


Syntax highlighting:
8	Make it easier to add new or modified syntax files.  Use a search path for
	syntax files instead of synload?
8	Allow the user to add items to the Syntax menu sorted, without having to
	change this for each release.
8	Add patch from Scott Bigham for back referencing.
	~/vim/patches/bigham.regexp3 .
8	Some syntax files set 'iskeyword'.  When switching to another filetype
	this isn't reset.  Add "set isk&" to all syntax files?
8	Add specific syntax item to match with parens/braces that don't have a
	match.  :syntax nomatch cParenError "("
8	Add a command to jump to the next characterw highlighted with "Error".
8	Highlight the text between two matching parens (e.g., with a grey
	background) when on one of the parens or in between them.
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	Make it possible to only highlight a sub-expression of a match.  Like
	using "\1" in a ":s" command.
8	Add a way of syncing where it always starts at the beginning of the file,
	to find the group where redrawing starts.  Useful for "#if 0" constructs
	in C. (Geddes)
	c.vim: Use advanced syncing to make long "#if 0" constructs work.
8	cpp.vim: In C++ it's allowed to use {} inside ().
8	Keep more context for syncing, but not for every line.  Make this settable
	with some command ":syn sync context=1000 skip=10" (store state for 1000
	lines, every 10 lines).
	Store the context with the window, instead of the buffer.  Useful when
	there are two windows on the same buffer.
	OR: Use three options:
	syntaxminsyncs: minimal number of sync points (for speedy small files)
	syntaxmaxsyncs: maximum number of sync points (for very big files)
	syntaxsyncdist: number of lines between two sync points (overruled by
		the other two options).
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	Make it possible for a skip pattern to include "$", so that it can skip
	over newlines for a "oneline" region.
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	Reduce the number of regexp in c.vim (for speed).
8	Add check for unterminated strings in c.vim, with a variable to switch it
	on: "c_strict_ansi".
8	Add a flag to temporarily disable highlighting.  Set it while dragging the
	status line.
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	Add "semitrans": Add highlighting.  E.g., make the text bold, but keep the
	colors.  And add colors, so that Green+Red becomes Yellow.
7	CTRL-] checks the highlight group for finding out what the tag is.
6	Not possible now: Two regions that add up.  E.g. for this html:
		<B> bold text <I> italic+bold text </B> italic text </I>
7	Not only change highlighting of text, also change what is displayed.  Can
	be used to hide tags, e.g.
		:syn region boldstuff start="<B>" display="" end="</B>" display=""
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?
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	Add more command line completion for :syntax.
8	Add more command line completion for :highlight.
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.
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)
8	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	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.
-	Allow the use of "blink".  Make a new attr when it's used.
-	Add line-continuation pattern for non-syncing items too?
7	Allow "\@1" in end (and skip) pattern, use first sub-match of start
	pattern.  To be used in e.g.: 'start="[/=+]" end="\@1"'  Also for Perl.
8	Add cursor-column highlighting.  Enable it with 'cursorcolumn' option, set
	highlighting with "CursorColumn" group.  Useful for aligning text.
	Also cursor-row highlighting.
-	Add possibility to highlight specific columns (for Fortran).  Or put a
	line in between columns (e.g. for 'textwidth').
-	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)
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?


Built-in script language:
8	Add referring to key options with "&t_xx".  Both for "echo &t_xx" and
	":let &t_xx =".  Useful for making portable mappings.
8	Allow range for ":exec".  Pass it on to the executed command. (Webb)
8	Add a way to catch errors:
		:try
		:  [commands that can fail]
		:catch [error-type]
		:  [error handling]
		:endtry
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
	$VIMRUNTIME/packages (or use a search path).
	Or add a FuncUndefined autocommand, so that the user can handle loading a
	function as he pleases. (Aaron)
	Pre-parse or compile Vim scripts into a bytecode.  Put the bytecode with
	the original script, with an ":if" around it, so that it's only used with
	a Vim that supports it.
8	The input() function should not read mapped characters, but always get
	characters from the user (or a script).  Need to change vgetorpeek() to
	ignore mapped characters.
8	Add functions:
		cursor(lnum, col)		Position cursor (when lnum or col 0 keep val)
		col("$")				Column number of last char in line.  See
								~/vim/patches/wall.coldollar .
		multibyteidx(string, idx) Byte index in multi-byte character.
		menuname({menu_name}, {idx})  get name of menu.  menuname("", 1)
								returns "File", menuname("File", 1) returns
								"Open...".
		menuarg({menu_name})	return argument of a menu item by name.
		mapname({idx}, mode)	return the name of the idx'th mapping.
		match({pat}, {string}, [count]) get index of count'th match
		stridx(bigstr, smallstr)  return index of first smallstr in bigstr
		strridx(bigstr, smallstr)  return index of last smallstr in bigstr
		sprintf(format, arg, ..) How to prevent a crash???
		inputpassword()			Ask user to enter password without showing it.
								Or extra argument to input() (Haegg)
		attributes()			return file protection flags "drwxrwxrwx"
		perl(cmd)				call Perl and return string
		shorten(fname)			shorten a file name, like home_replace()
		input(prompt, complete)	like input() but do specified completion
		filewritable()			like filereadable()
		getfperm()				file permissions, in form "rwxrwxrwx"
		getfsize()				file size in bytes (directory is 0)
		getftype()				"file", "dir", "link", "other"?
		getbufvar({bufid}, {name})
		setbufvar({bufid}, {name}, {value})
								get/set value of variable {name} in buffer
								{bufid}  See ~/vim/patches/aaron.getbufvar4
		setwinvar()
		getwinvar()
		libcall()				Allow more than one argument.
		libcallnr()				Like libcall(), but function returns a number.
		fnamemod({fname}, {mod})	{mod} can be ":p:h" etc., to be applied to
								{fname}
		getchar()				get one character from the user.
		confirm()				add "flags" argument, with 'v' for vertical
								layout and 'c' for console dialog.  Also add
								'c' to 'guioptions' (for all dialogs) (Haegg)
		toupper({string})
		tolower({string})
		filter({cmd} [, {string}])	Filter {string} through the shell command
								{cmd} and return the result.  If {string} is
								omitted no input is given to {cmd}.
		getkey()				Like input() but get only one char.
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	When starting to source a vim script, delete all functions that it has
	previously defined.  Avoids using ":fun!" all the time.
8	Include support for arrays?  Patch from Robert Webb.
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	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.
