" surround.vim - Surroundings
" Maintainer: Tim Pope <vimNOSPAM@tpope.info>
" $Id$
"
" Usage:
"
" "ds" is a mapping which deletes the surroundings of a text object--the
" difference between the "inner" object and "an" object. See the :help on
" text-objects for details. This is easiest to understand with some examples;
" in the following, * represents the cursor position.
"
" Old Keystroke New
" "Hello *world!" ds" Hello world!
" (123+4*56)/2 ds) 123+456/2
" <div>Yo!</div> dst Yo!
"
" "cs" does as above, but rather than remove the surroundings, it replaces
" them with something else. It takes two arguments. Once again, examples are
" in order. (Details about the second argument, the replacement character,
" are below).
"
" Old Keystroke New
" "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 motion or text object as the first object, and wraps it using
" the second argument as with "cs".
"
" Old Keystroke New
" Hello w*orld! ysiw) Hello (world)!
"
" As a special case, "yss" operates on the current line, ignoring leading
" whitespace.
"
" Old Keystroke New
" Hello w*orld! yssB {Hello world!}
"
" Finally, in visual mode, a simple "s" with an argument wraps the selection.
" Note that "s" already has a valid meaning in visual mode, but it is
" identical to "c". If you have muscle memory for "s" and would like to use a
" different key, add your own mapping and the existing one will be disabled.
"
" vmap S <Plug>VSurround
"
" Replacements:
"
" A replacement argument is a single character. The default behavior is to
" insert that character before and after the text.
"
" If ")", "]", "}", or ">" are used, the text is wrapped in the appropriate
" open/close pair of characters. "(", "[", and "{" behave similarly but add
" an additional space to the inside. "B" and "b" are synonymous with "}" and
" ")".
"
" 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.
" End your input by pressing "<CR>" or ">".
"
" Customizing:
"
" The following adds a potential replacement on "-" (ASCII 45) in PHP files.
" (To determine the ASCII code to use, :echo char2nr("-")). The newline will
" be replaced by the original text.
"
" autocmd FileType php let b:surround_45 = "<?php \n ?>"
"
" This can be used in a PHP file as in the following example.
"
" Old Keystroke New
" print "Hello *world!" yss- <?php print "Hello world!" ?>
"
" Additionally, one can use a global variable for globally available
" replacements.
"
" let g:surround_45 = "<% \n %>"
"
" Issues:
"
" Vim could potentially get confused when deleting/changing occurs at the very
" end of the line. Report any repeatable instances of this.
"
" Do we need to use inputsave() / inputrestore() with the tag replacement?
"
" Customization isn't very flexible. Need a system that allows for prompting
" similar to with tags.
"
" Reindenting is handled haphazardly. Need to decide the most appropriate
" behavior and implement it.
