Similar to |v_a[|. - A [count] is ignored, and only the first character of the closing - pattern is selected. - -In Vim, as in plain vi, the percent key, |%|, jumps the cursor from a brace, -bracket, or paren to its match. This can be configured with the 'matchpairs' -option. The matchit plugin extends this in several ways: - - You can match whole words, such as "if" and "endif", not just - single characters. You can also specify a |regular-expression|. - You can define groups with more than two words, such as "if", - "else", "endif". Banging on the "%" key will cycle from the "if" to - the first "else", the next "else", ..., the closing "endif", and back - to the opening "if". Nested structures are skipped. Using |g%| goes - in the reverse direction. - By default, words inside comments and strings are ignored, unless - the cursor is inside a comment or string when you type "%". If the - only thing you want to do is modify the behavior of "%" so that it - behaves this way, you do not have to define |b:match_words|, since the - script uses the 'matchpairs' option as well as this variable. - -See |matchit-details| for details on what the script does, and |b:match_words| -for how to specify matching patterns. - -MODES: *matchit-modes* *matchit-v_%* *matchit-o_%* - -Mostly, % and related motions (|g%| and |[%| and |]%|) work just like built-in -|motion| commands in |Operator-pending| and |Visual| modes. However, you -cannot make these motions |linewise| or |characterwise|, since the |:omap|s -that define them start with "v" in order to make the default behavior -inclusive. (See |o_v|.) In other words, "dV%" will not work. The -work-around is to go through Visual mode: "V%d" will work. - -LANGUAGES: *matchit-languages* - -Currently, the following languages are supported: Ada, ASP with VBS, Csh, -DTD, Entity, Essbase, Fortran, HTML, JSP (same as HTML), LaTeX, Lua, Pascal, -SGML, Shell, Tcsh, Vim, XML. Other languages may already have support via -the default |filetype-plugin|s in the standard vim distribution. - -To support a new language, see |matchit-newlang| below. - -DETAILS: *matchit-details* *matchit-parse* - -Here is an outline of what matchit.vim does each time you hit the "%" key. If -there are |backref|s in |b:match_words| then the first step is to produce a -version in which these back references have been eliminated; if there are no -|backref|s then this step is skipped. This step is called parsing. For -example, "\(foo\|bar\):end\1" is parsed to yield -"\(foo\|bar\):end\(foo\|bar\)". This can get tricky, especially if there are -nested groups. If debugging is turned on, the parsed version is saved as -|b:match_pat|. - - *matchit-choose* -Next, the script looks for a word on the current line that matches the pattern -just constructed. It includes the patterns from the 'matchpairs' option. -The goal is to do what you expect, which turns out to be a little complicated. -The script follows these rules: - - Insist on a match that ends on or after the cursor. - Prefer a match that includes the cursor position (that is, one that - starts on or before the cursor). - Prefer a match that starts as close to the cursor as possible. - If more than one pattern in |b:match_words| matches, choose the one - that is listed first. - -Examples: - - Suppose you > - :let b:match_words = '<:>,<tag>:</tag>' -< and hit "%" with the cursor on or before the "<" in "a <tag> is born". - The pattern '<' comes first, so it is preferred over '<tag>', which - also matches. If the cursor is on the "t", however, then '<tag>' is - preferred, because this matches a bit of text containing the cursor. - If the two groups of patterns were reversed then '<' would never be - preferred. - - Suppose you > - :let b:match_words = 'if:end if' -< (Note the space!) and hit "%" with the cursor at the end of "end if". - Then "if" matches, which is probably not what you want, but if the - cursor starts on the "end " then "end if" is chosen. (You can avoid - this problem by using a more complicated pattern.) - -If there is no match, the cursor does not move. (Before version 1.13 of the -script, it would fall back on the usual behavior of |%|). If debugging is -turned on, the matched bit of text is saved as |b:match_match| and the cursor -column of the start of the match is saved as |b:match_col|. - -Next, the script looks through |b:match_words| (original and parsed versions) -for the group and pattern that match. If debugging is turned on, the group is -saved as |b:match_ini| (the first pattern) and |b:match_tail| (the rest). If -there are |backref|s then, in addition, the matching pattern is saved as -|b:match_word| and a table of translations is saved as |b:match_table|. If -there are |backref|s, these are determined from the matching pattern and -|b:match_match| and substituted into each pattern in the matching group. - -The script decides whether to search forwards or backwards and chooses -arguments for the |searchpair()| function. Then, the cursor is moved to the -start of the match, and |searchpair()| is called. By default, matching -structures inside strings and comments are ignored. This can be changed by -setting |b:match_skip|. - -============================================================================== -2. Activation *matchit-activate* - -You can use this script as a plugin, by copying it to your plugin directory. -See |add-global-plugin| for instructions. You can also add a line to your -|vimrc| file, such as > - :source $VIMRUNTIME/macros/matchit.vim -or > - :runtime macros/matchit.vim -Either way, the script should start working the next time you start up Vim. - -(Earlier versions of the script did nothing unless a |buffer-variable| named -|b:match_words| was defined. Even earlier versions contained autocommands -that set this variable for various file types. Now, |b:match_words| is -defined in many of the default |filetype-plugin|s instead.) - -For a new language, you can add autocommands to the script or to your vimrc -file, but the recommended method is to add a line such as > - let b:match_words = '\<foo\>:\<bar\>' -to the |filetype-plugin| for your language. See |b:match_words| below for how -this variable is interpreted. - -TROUBLESHOOTING *matchit-troubleshoot* - -The script should work in most installations of Vim. It may not work if Vim -was compiled with a minimal feature set, for example if the |+syntax| option -was not enabled. If your Vim has support for syntax compiled in, but you do -not have |syntax| highlighting turned on, matchit.vim should work, but it may -fail to skip matching groups in comments and strings. If the |filetype| -mechanism is turned off, the |b:match_words| variable will probably not be -defined automatically. - -============================================================================== -3. Configuration *matchit-configure* - -There are several variables that govern the behavior of matchit.vim. Note -that these are variables local to the buffer, not options, so use |:let| to -define them, not |:set|. Some of these variables have values that matter; for -others, it only matters whether the variable has been defined. All of these -can be defined in the |filetype-plugin| or autocommand that defines -|b:match_words| or "on the fly." - -The main variable is |b:match_words|. It is described in the section below on -supporting a new language. - - *MatchError* *matchit-hl* *matchit-highlight* -MatchError is the highlight group for error messages from the script. By -default, it is linked to WarningMsg. If you do not want to be bothered by -error messages, you can define this to be something invisible. For example, -if you use the GUI version of Vim and your command line is normally white, you -can do > - :hi MatchError guifg=white guibg=white -< - *b:match_ignorecase* -If you > - :let b:match_ignorecase = 1 -then matchit.vim acts as if 'ignorecase' is set: for example, "end" and "END" -are equivalent. If you > - :let b:match_ignorecase = 0 -then matchit.vim treats "end" and "END" differently. (There will be no -b:match_infercase option unless someone requests it.) - - *b:match_debug* -Define b:match_debug if you want debugging information to be saved. See -|matchit-debug|, below. - - *b:match_skip* -If b:match_skip is defined, it is passed as the skip argument to -|searchpair()|. This controls when matching structures are skipped, or -ignored. By default, they are ignored inside comments and strings, as -determined by the |syntax| mechanism. (If syntax highlighting is turned off, -nothing is skipped.) You can set b:match_skip to a string, which evaluates to -a non-zero, numerical value if the match is to be skipped or zero if the match -should not be skipped. In addition, the following special values are -supported by matchit.vim: - s:foo becomes (current syntax item) =~ foo - S:foo becomes (current syntax item) !~ foo - r:foo becomes (line before cursor) =~ foo - R:foo becomes (line before cursor) !~ foo -(The "s" is meant to suggest "syntax", and the "r" is meant to suggest -"regular expression".) - -Examples: - - You can get the default behavior with > - :let b:match_skip = 's:comment\|string' -< - If you want to skip matching structures unless they are at the start - of the line (ignoring whitespace) then you can > - :let b:match_skip = 'R:^\s*' -< Do not do this if strings or comments can span several lines, since - the normal syntax checking will not be done if you set b:match_skip. - - In LaTeX, since "%" is used as the comment character, you can > - :let b:match_skip = 'r:%' -< Unfortunately, this will skip anything after "\%", an escaped "%". To - allow for this, and also "\\%" (an excaped backslash followed by the - comment character) you can > - :let b:match_skip = 'r:\(^\|[^\\]\)\(\\\\\)*%' -< - See the $VIMRUNTIME/ftplugin/vim.vim for an example that uses both - syntax and a regular expression. - -============================================================================== -4. Supporting a New Language *matchit-newlang* - *b:match_words* -In order for matchit.vim to support a new language, you must define a suitable -pattern for |b:match_words|. You may also want to set some of the -|matchit-configure| variables, as described above. If your language has a -complicated syntax, or many keywords, you will need to know something about -Vim's |regular-expression|s. - -The format for |b:match_words| is similar to that of the 'matchpairs' option: -it is a comma (,)-separated list of groups; each group is a colon(:)-separated -list of patterns (regular expressions). Commas and backslashes that are part -of a pattern should be escaped with backslashes ('\:' and '\,'). It is OK to -have only one group; the effect is undefined if a group has only one pattern. -A simple example is > - :let b:match_words = '\<if\>:\<endif\>,' - \ . '\<while\>:\<continue\>:\<break\>:\<endwhile\>' -(In Vim regular expressions, |\<| and |\>| denote word boundaries. Thus "if" -matches the end of "endif" but "\<if\>" does not.) Then banging on the "%" -key will bounce the cursor between "if" and the matching "endif"; and from -"while" to any matching "continue" or "break", then to the matching "endwhile" -and back to the "while". It is almost always easier to use |literal-string|s -(single quotes) as above: '\<if\>' rather than "\\<if\\>" and so on. - -Exception: If the ":" character does not appear in b:match_words, then it is -treated as an expression to be evaluated. For example, > - :let b:match_words = 'GetMatchWords()' -allows you to define a function. This can return a different string depending -on the current syntax, for example. - -Once you have defined the appropriate value of |b:match_words|, you will -probably want to have this set automatically each time you edit the -appropriate file type. The recommended way to do this is by adding the -definition to a |filetype-plugin| file. - -Tips: Be careful that your initial pattern does not match your final pattern. -See the example above for the use of word-boundary expressions. It is usually -better to use ".\{-}" (as many as necessary) instead of ".*" (as many as -possible). See |\{-|. For example, in the string "<tag>label</tag>", "<.*>" -matches the whole string whereas "<.\{-}>" and "<[^>]*>" match "<tag>" and -"</tag>". - - *matchit-spaces* *matchit-s:notend* -If "if" is to be paired with "end if" (Note the space!) then word boundaries -are not enough. Instead, define a regular expression s:notend that will match -anything but "end" and use it as follows: > - :let s:notend = '\%(\<end\s\+\)\@<!' - :let b:match_words = s:notend . '\<if\>:\<end\s\+if\>' -< *matchit-s:sol* -This is a simplified version of what is done for Ada. The s:notend is a -|script-variable|. Similarly, you may want to define a start-of-line regular -expression > - :let s:sol = '\%(^\|;\)\s*' -if keywords are only recognized after the start of a line or after a -semicolon (;), with optional white space. - - *matchit-backref* *matchit-\1* -In any group, the expressions |\1|, |\2|, ..., |\9| refer to parts of the -INITIAL pattern enclosed in |\(|escaped parentheses|\)|. These are referred -to as back references, or backrefs. For example, > - :let b:match_words = '\<b\(o\+\)\>:\(h\)\1\>' -means that "bo" pairs with "ho" and "boo" pairs with "hoo" and so on. Note -that "\1" does not refer to the "\(h\)" in this example. If you have -"\(nested \(parentheses\)\) then "\d" refers to the d-th "\(" and everything -up to and including the matching "\)": in "\(nested\(parentheses\)\)", "\1" -refers to everything and "\2" refers to "\(parentheses\)". If you use a -variable such as |s:notend| or |s:sol| in the previous paragraph then remember -to count any "\(" patterns in this variable. You do not have to count groups -defined by |\%(\)|. - -It should be possible to resolve back references from any pattern in the -group. For example, > - :let b:match_words = '\(foo\)\(bar\):more\1:and\2:end\1\2' -would not work because "\2" cannot be determined from "morefoo" and "\1" -cannot be determined from "andbar". On the other hand, > - :let b:match_words = '\(\(foo\)\(bar\)\):\3\2:end\1' -should work (and have the same effect as "foobar:barfoo:endfoobar"), although -this has not been thoroughly tested. - -You can use |zero-width| patterns such as |\@<=| and |\zs|. (The latter has -not been thouroughly tested in matchit.vim.) For example, if the keyword "if" -must occur at the start of the line, with optional white space, you might use -the pattern "\(^\s*\)\@<=if" so that the cursor will end on the "i" instead of -at the start of the line. For another example, if HTML had only one tag then -one could > - :let b:match_words = '<:>,<\@<=tag>:<\@<=/tag>' -so that "%" can bounce between matching "<" and ">" pairs or (starting on -"tag" or "/tag") between matching tags. Without the |\@<=|, the script would -bounce from "tag" to the "<" in "</tag>", and another "%" would not take you -back to where you started. - -DEBUGGING *matchit-debug* *:MatchDebug* - -If you are having trouble figuring out the appropriate definition of -|b:match_words| then you can take advantage of the same information I use when -debugging the script. This is especially true if you are not sure whether -your patterns or my script are at fault! To make this more convenient, I have -made the command :MatchDebug, which defines the variable |b:match_debug| and -creates a Matchit menu. This menu makes it convenient to check the values of -the variables described below. You will probably also want to read -|matchit-details| above. - -Defining the variable |b:match_debug| causes the script to set the following -variables, each time you hit the "%" key. Several of these are only defined -if |b:match_words| includes |backref|s. - - *b:match_pat* -The b:match_pat variable is set to |b:match_words| with |backref|s parsed. - *b:match_match* -The b:match_match variable is set to the bit of text that is recognized as a -match. - *b:match_col* -The b:match_col variable is set to the cursor column of the start of the -matching text. - *b:match_wholeBR* -The b:match_wholeBR variable is set to the comma-separated group of patterns -that matches, with |backref|s unparsed. - *b:match_iniBR* -The b:match_iniBR variable is set to the first pattern in |b:match_wholeBR|. - *b:match_ini* -The b:match_ini variable is set to the first pattern in |b:match_wholeBR|, -with |backref|s resolved from |b:match_match|. - *b:match_tail* -The b:match_tail variable is set to the remaining patterns in -|b:match_wholeBR|, with |backref|s resolved from |b:match_match|. - *b:match_word* -The b:match_word variable is set to the pattern from |b:match_wholeBR| that -matches |b:match_match|. - *b:match_table* -The back reference '\'.d refers to the same thing as '\'.b:match_table[d] in -|b:match_word|. - -============================================================================== -5. Known Bugs and Limitations *matchit-bugs* - -Just because I know about a bug does not mean that it is on my todo list. I -try to respond to reports of bugs that cause real problems. If it does not -cause serious problems, or if there is a work-around, a bug may sit there for -a while. Moral: if a bug (known or not) bothers you, let me know. - -The various |:vmap|s defined in the script (%, |g%|, |[%|, |]%|, |a%|) may -have undesired effects in Select mode |Select-mode-mapping|. At least, if you -want to replace the selection with any character in "ag%[]" there will be a -pause of |'updatetime'| first. - -It would be nice if "\0" were recognized as the entire pattern. That is, it -would be nice if "foo:\end\0" had the same effect as "\(foo\):\end\1". I may -try to implement this in a future version. (This is not so easy to arrange as -you might think!) - -============================================================================== -vim:tw=78:fo=tcq2: diff --git a/base/.vim/doc/tags b/base/.vim/doc/tags deleted file mode 100644 index 4ccdc87..0000000 --- a/base/.vim/doc/tags +++ /dev/null @@ -1,50 +0,0 @@ -:MatchDebug matchit.txt /*:MatchDebug* -MatchError matchit.txt /*MatchError* -[% matchit.txt /*[%* -]% matchit.txt /*]%* -b:match_col matchit.txt /*b:match_col* -b:match_debug matchit.txt /*b:match_debug* -b:match_ignorecase matchit.txt /*b:match_ignorecase* -b:match_ini matchit.txt /*b:match_ini* -b:match_iniBR matchit.txt /*b:match_iniBR* -b:match_match matchit.txt /*b:match_match* -b:match_pat matchit.txt /*b:match_pat* -b:match_skip matchit.txt /*b:match_skip* -b:match_table matchit.txt /*b:match_table* -b:match_tail matchit.txt /*b:match_tail* -b:match_wholeBR matchit.txt /*b:match_wholeBR* -b:match_word matchit.txt /*b:match_word* -b:match_words matchit.txt /*b:match_words* -g% matchit.txt /*g%* -matchit matchit.txt /*matchit* -matchit-% matchit.txt /*matchit-%* -matchit-\1 matchit.txt /*matchit-\\1* -matchit-activate matchit.txt /*matchit-activate* -matchit-backref matchit.txt /*matchit-backref* -matchit-bugs matchit.txt /*matchit-bugs* -matchit-choose matchit.txt /*matchit-choose* -matchit-configure matchit.txt /*matchit-configure* -matchit-debug matchit.txt /*matchit-debug* -matchit-details matchit.txt /*matchit-details* -matchit-highlight matchit.txt /*matchit-highlight* -matchit-hl matchit.txt /*matchit-hl* -matchit-intro matchit.txt /*matchit-intro* -matchit-languages matchit.txt /*matchit-languages* -matchit-modes matchit.txt /*matchit-modes* -matchit-newlang matchit.txt /*matchit-newlang* -matchit-o_% matchit.txt /*matchit-o_%* -matchit-parse matchit.txt /*matchit-parse* -matchit-s:notend matchit.txt /*matchit-s:notend* -matchit-s:sol matchit.txt /*matchit-s:sol* -matchit-spaces matchit.txt /*matchit-spaces* -matchit-troubleshoot matchit.txt /*matchit-troubleshoot* -matchit-v_% matchit.txt /*matchit-v_%* -matchit.txt matchit.txt /*matchit.txt* -matchit.vim matchit.txt /*matchit.vim* -o_[% matchit.txt /*o_[%* -o_]% matchit.txt /*o_]%* -o_g% matchit.txt /*o_g%* -v_[% matchit.txt /*v_[%* -v_]% matchit.txt /*v_]%* -v_a% matchit.txt /*v_a%* -v_g% matchit.txt /*v_g%* |
