Examples +of surroundings include parentheses, quotes, and HTML tags. They are +closely related to what Vim refers to as |text-objects|. Provided +are mappings to allow for removing, changing, and adding surroundings. + +Details follow on the exact semantics, but first, consider the following +examples. An asterisk (*) is used to denote the cursor position. + + Old text Command New text ~ + "Hello *world!" ds" Hello world! + [123+4*56]/2 cs]) (123+456)/2 + "Look ma, I'm *HTML!" cs"<q> <q>Look ma, I'm HTML!</q> + if *x>3 { ysW( if ( x>3 ) { + my $str = *whee!; vllllS' my $str = 'whee!'; + +While a few features of this plugin will work in older versions of Vim, +Vim 7 is recommended for full functionality. + +MAPPINGS *surround-mappings* + +Delete surroundings is *ds* . The next character given determines the target +to delete. The exact nature of the target is explained in |surround-targets| +but essentially it is the last character of a |text-object|. This mapping +deletes the difference between the "i"nner object and "a"n object. This is +easiest to understand with some examples: + + Old text Command New text ~ + "Hello *world!" ds" Hello world! + (123+4*56)/2 ds) 123+456/2 + <div>Yo!*</div> dst Yo! + +Change surroundings is *cs* . It takes two arguments, a target like with +|ds|, and a replacement. *cS* changes surroundings, placing the surrounded +text on its own line(s) like |yS|. Details about the second argument can be +found below in |surround-replacements|. Once again, examples are in order. + + Old text Command New text ~ + "Hello *world!" cs"' 'Hello world!' + "Hello *world!" cs"<q> <q>Hello world!</q> + (123+4*56)/2 cs)] [123+456]/2 + (123+4*56)/2 cs)[ [ 123+456 ]/2 + <div>Yo!*</div> cst<p> <p>Yo!</p> + +*ys* takes a valid Vim motion or text object as the first object, and wraps +it using the second argument as with |cs|. (It's a stretch, but a good +mnemonic for "ys" is "you surround".) + + Old text Command New text ~ + Hello w*orld! ysiw) Hello (world)! + +As a special case, *yss* operates on the current line, ignoring leading +whitespace. + + Old text Command New text ~ + Hello w*orld! yssB {Hello world!} + +There is also *yS* and *ySS* which indent the surrounded text and place it +on a line of its own. + +In visual mode, a simple "S" with an argument wraps the selection. This is +referred to as the *vS* mapping, although ordinarily there will be +additional keystrokes between the v and S. In linewise visual mode, the +surroundings are placed on separate lines and indented. In blockwise visual +mode, each line is surrounded. + +A "gS" in visual mode, known as *vgS* , behaves similarly. In linewise visual +mode, the automatic indenting is suppressed. In blockwise visual mode, this +enables surrounding past the end of the line with 'virtualedit' set (there +seems to be no way in Vim Script to differentiate between a jagged end of line +selection and a virtual block selected past the end of the line, so two maps +were needed). + + *i_CTRL-G_s* *i_CTRL-G_S* +Finally, there is an experimental insert mode mapping on <C-G>s and <C-S>. +Beware that the latter won't work on terminals with flow control (if you +accidentally freeze your terminal, use <C-Q> to unfreeze it). The mapping +inserts the specified surroundings and puts the cursor between them. If, +immediately after the mapping and before the replacement, a second <C-S> or +carriage return is pressed, the prefix, cursor, and suffix will be placed on +three separate lines. <C-G>S (not <C-G>s) also exhibits this behavior. + +TARGETS *surround-targets* + +The |ds| and |cs| commands both take a target as their first argument. The +possible targets are based closely on the |text-objects| provided by Vim. +All targets are currently just one character. + +Eight punctuation marks, (, ), {, }, [, ], <, and >, represent themselves +and their counterparts. If the opening mark is used, contained whitespace is +also trimmed. The targets b, B, r, and a are aliases for ), }, ], and > +(the first two mirror Vim; the second two are completely arbitrary and +subject to change). + +Three quote marks, ', ", `, represent themselves, in pairs. They are only +searched for on the current line. + +A t is a pair of HTML or XML tags. See |tag-blocks| for details. Remember +that you can specify a numerical argument if you want to get to a tag other +than the innermost one. + +The letters w, W, and s correspond to a |word|, a |WORD|, and a |sentence|, +respectively. These are special in that they have nothing to delete, and +used with |ds| they are a no-op. With |cs|, one could consider them a +slight shortcut for ysi (cswb == ysiwb, more or less). + +A p represents a |paragraph|. This behaves similarly to w, W, and s above; +however, newlines are sometimes added and/or removed. + +REPLACEMENTS *surround-replacements* + +A replacement argument is a single character, and is required by |cs|, |ys|, +and |vS|. Undefined replacement characters (with the exception of alphabetic +characters) default to placing themselves at the beginning and end of the +destination, which can be useful for characters like / and |. + +If either ), }, ], or > is used, the text is wrapped in the appropriate pair +of characters. Similar behavior can be found with (, {, and [ (but not <), +which append an additional space to the inside. Like with the targets above, +b, B, r, and a are aliases for ), }, ], and >. To fulfill the common need for +code blocks in C-style languages, <C-}> (which is really <C-]>) adds braces on +lines separate from the content. + +If t or < is used, Vim prompts for an HTML/XML tag to insert. You may specify +attributes here and they will be stripped from the closing tag. If replacing a +tag, its attributes are kept in the new tag. End your input with > to discard +the those attributes. If <C-T> is used, the tags will appear on lines by +themselves. + +If s is used, a leading but not trailing space is added. This is useful for +removing parentheses from a function call with csbs. + +CUSTOMIZING *surround-customizing* + +The following adds a potential replacement on "-" (ASCII 45) in PHP files. +(To determine the ASCII code to use, :echo char2nr("-")). The carriage +return will be replaced by the original text. +> + autocmd FileType php let b:surround_45 = "<?php \r ?>" +< +This can be used in a PHP file as in the following example. + + Old text Command New text ~ + print "Hello *world!" yss- <?php print "Hello world!" ?> + +Additionally, one can use a global variable for globally available +replacements. +> + let g:surround_45 = "<% \r %>" + let g:surround_61 = "<%= \r %>" +< +Advanced, experimental, and subject to change: One can also prompt for +replacement text. The syntax for this is to surround the replacement in pairs +of low numbered control characters. If this sounds confusing, that's because +it is (but it makes the parsing easy). Consider the following example for a +LaTeX environment on the "l" replacement. +> + let g:surround_108 = "\\begin{\1environment: \1}\r\\end{\1\1}" +< +When this replacement is used, the user is prompted with an "environment: " +prompt for input. This input is inserted between each set of \1's. +Additional inputs up to \7 can be used. + +Furthermore, one can specify a regular expression substitution to apply. +> + let g:surround_108 = "\\begin{\1environment: \1}\r\\end{\1\r}.*\r\1}" +< +This will remove anything after the first } in the input when the text is +placed within the \end{} slot. The first \r marks where the pattern begins, +and the second where the replacement text begins. + +Here's a second example for creating an HTML <div>. The substitution cleverly +prompts for an id, but only adds id="" if it is non-blank. You may have to +read this one a few times slowly before you understand it. +> + let g:surround_{char2nr("d")} = "<div\1id: \r..*\r id=\"&\"\1>\r</div>" +< +Inputting text replacements is a proof of concept at this point. The ugly, +unintuitive interface and the brevity of the documentation reflect this. + +Finally, It is possible to always append a string to surroundings in insert +mode (and only insert mode). This is useful with certain plugins and mappings +that allow you to jump to such markings. +> + let g:surround_insert_tail = "<++>" +< +ISSUES *surround-issues* + +Vim could potentially get confused when deleting/changing occurs at the very +end of the line. Please report any repeatable instances of this. + +Do we need to use |inputsave()|/|inputrestore()| with the tag replacement? + +Indenting is handled haphazardly. Need to decide the most appropriate +behavior and implement it. Right now one can do :let b:surround_indent = 1 +(or the global equivalent) to enable automatic re-indenting by Vim via |=|; +should this be the default? + + vim:tw=78:ts=8:ft=help:norl: diff --git a/vim/vim-surround/plugin/surround.vim b/vim/vim-surround/plugin/surround.vim new file mode 100644 index 0000000..46f3252 --- /dev/null +++ b/vim/vim-surround/plugin/surround.vim @@ -0,0 +1,598 @@ +" surround.vim - Surroundings +" Author: Tim Pope <http://tpo.pe/> +" Version: 2.1 +" GetLatestVimScripts: 1697 1 :AutoInstall: surround.vim + +if exists("g:loaded_surround") || &cp || v:version < 700 + finish +endif +let g:loaded_surround = 1 + +" Input functions {{{1 + +function! s:getchar() + let c = getchar() + if c =~ '^\d\+$' + let c = nr2char(c) + endif + return c +endfunction + +function! s:inputtarget() + let c = s:getchar() + while c =~ '^\d\+$' + let c .= s:getchar() + endwhile + if c == " " + let c .= s:getchar() + endif + if c =~ "\<Esc>\|\<C-C>\|\0" + return "" + else + return c + endif +endfunction + +function! s:inputreplacement() + let c = s:getchar() + if c == " " + let c .= s:getchar() + endif + if c =~ "\<Esc>" || c =~ "\<C-C>" + return "" + else + return c + endif +endfunction + +function! s:beep() + exe "norm! \<Esc>" + return "" +endfunction + +function! s:redraw() + redraw + return "" +endfunction + +" }}}1 + +" Wrapping functions {{{1 + +function! s:extractbefore(str) + if a:str =~ '\r' + return matchstr(a:str,'.*\ze\r') + else + return matchstr(a:str,'.*\ze\n') + endif +endfunction + +function! s:extractafter(str) + if a:str =~ '\r' + return matchstr(a:str,'\r\zs.*') + else + return matchstr(a:str,'\n\zs.*') + endif +endfunction + +function! s:fixindent(str,spc) + let str = substitute(a:str,'\t',repeat(' ',&sw),'g') + let spc = substitute(a:spc,'\t',repeat(' ',&sw),'g') + let str = substitute(str,'\(\n\|\%^\).\@=','\1'.spc,'g') + if ! &et + let str = substitute(str,'\s\{'.&ts.'\}',"\t",'g') + endif + return str +endfunction + +function! s:process(string) + let i = 0 + for i in range(7) + let repl_{i} = '' + let m = matchstr(a:string,nr2char(i).'.\{-\}\ze'.nr2char(i)) + if m != '' + let m = substitute(strpart(m,1),'\r.*','','') + let repl_{i} = input(match(m,'\w\+$') >= 0 ? m.': ' : m) + endif + endfor + let s = "" + let i = 0 + while i < strlen(a:string) + let char = strpart(a:string,i,1) + if char2nr(char) < 8 + let next = stridx(a:string,char,i+1) + if next == -1 + let s .= char + else + let insertion = repl_{char2nr(char)} + let subs = strpart(a:string,i+1,next-i-1) + let subs = matchstr(subs,'\r.*') + while subs =~ '^\r.*\r' + let sub = matchstr(subs,"^\r\\zs[^\r]*\r[^\r]*") + let subs = strpart(subs,strlen(sub)+1) + let r = stridx(sub,"\r") + let insertion = substitute(insertion,strpart(sub,0,r),strpart(sub,r+1),'') + endwhile + let s .= insertion + let i = next + endif + else + let s .= char + endif + let i += 1 + endwhile + return s +endfunction + +function! s:wrap(string,char,type,removed,special) + let keeper = a:string + let newchar = a:char + let s:input = "" + let type = a:type + let linemode = type ==# 'V' ? 1 : 0 + let before = "" + let after = "" + if type ==# "V" + let initspaces = matchstr(keeper,'\%^\s*') + else + let initspaces = matchstr(getline('.'),'\%^\s*') + endif + let pairs = "b()B{}r[]a<>" + let extraspace = "" + if newchar =~ '^ ' + let newchar = strpart(newchar,1) + let extraspace = ' ' + endif + let idx = stridx(pairs,newchar) + if newchar == ' ' + let before = '' + let after = '' + elseif exists("b:surround_".char2nr(newchar)) + let all = s:process(b:surround_{char2nr(newchar)}) + let before = s:extractbefore(all) + let after = s:extractafter(all) + elseif exists("g:surround_".char2nr(newchar)) + let all = s:process(g:surround_{char2nr(newchar)}) + let before = s:extractbefore(all) + let after = s:extractafter(all) + elseif newchar ==# "p" + let before = "\n" + let after = "\n\n" + elseif newchar ==# 's' + let before = ' ' + let after = '' + elseif newchar ==# ':' + let before = ':' + let after = '' + elseif newchar =~# "[tT\<C-T><]" + let dounmapp = 0 + let dounmapb = 0 + if !maparg(">","c") + let dounmapb = 1 + " Hide from AsNeeded + exe "cn"."oremap > ><CR>" + endif + let default = "" + if newchar ==# "T" + if !exists("s:lastdel") + let s:lastdel = "" + endif + let default = matchstr(s:lastdel,'<\zs.\{-\}\ze>') + endif + let tag = input("<",default) + if dounmapb + silent! cunmap > + endif + let s:input = tag + if tag != "" + let keepAttributes = ( match(tag, ">$") == -1 ) + let tag = substitute(tag,'>*$','','') + let attributes = "" + if keepAttributes + let attributes = matchstr(a:removed, '<[^ \t\n]\+\zs\_.\{-\}\ze>') + endif + let s:input = tag .
