INTRODUCTION					*neocomplcache-snippets-complete-introduction*

This source analyzes snippet files for completion, offers functionality
similar to snipMate.vim or snippetsEmu.vim.  Since you can choose snippet with
neocomplcache interface, you might have less trouble learning it.

==============================================================================
INSTALL						*neocomplcache-snippets-complete-install*

1: Install neocomplcache (https://github.com/Shougo/neocomplcache).
2: Extract the file and put files in your Vim directory
   (usually ~/.vim/ or Program Files/Vim/vimfiles on Windows).

==============================================================================
INTERFACE					*neocomplcache-snippets-complete-interface*

------------------------------------------------------------------------------
COMMANDS 					*neocomplcache-snippets-complete-commands*

:NeoComplCacheCachingSnippets [filetype]	*:NeoComplCacheCachingSnippets*
		Makes cache of [filetype] snippets.  It automatically selects
		current buffer's filetype unless you specify [filetype].

:NeoComplCacheEditSnippets [filetype]		*:NeoComplCacheEditSnippets*
		Opens [filetype] snippets to edit.  It automatically selects
		current buffer's filetype unless you specify [filetype].

		If [filetype] snippet file doesn't exist, it creates one
		automatically.

		This command edits a snippet file in
		|g:neocomplcache_snippets_dir| with precedence.
		Re-cache will be done automatically when you save the file.

:NeoComplCacheEditRuntimeSnippets [filetype]	*:NeoComplCacheEditRuntimeSnippets*
		Opens [filetype] snippets to edit.  It automatically selects
		current buffer's filetype unless you specify [filetype].

		If [filetype] snippet file doesn't exist, it creates one
		automatically.

		This command edits a runtime snippet file with
		snippets_complete.  Re-cache will be done automatically when
		you save the file.

------------------------------------------------------------------------------
VARIABLES 					*neocomplcache-snippets-complete-variables*

g:neocomplcache_snippets_dir			*g:neocomplcache_snippets_dir*
		This variable appoints a path to user-defined snippet files.
		You can set multiple values in comma-separated form.
		If the directory doesn't exist, it is ignored.

		User defined snippets were read after normal snippet files,
		so redundant snippets will be overwritten.

		This variable doesn't exist unless you declare it.

g:neocomplcache_disable_select_mode_mappings	*g:neocomplcache_disable_select_mode_mappings*
		This variable controls whether to disable Key-mappings in
		|Select-mode| when snippets_complete performs.  Usually you
		had better enable it.

		Default value is 1.

g:neocomplcache_snippets_disable_runtime_snippets
						*g:neocomplcache_snippets_disable_runtime_snippets*
		If this variable is 1, runtime snippets won't be loaded.
		This variable is useful to avoid snippets conflictions.

		Default value is 0.

------------------------------------------------------------------------------
KEY MAPPINGS 					*neocomplcache-snippets-complete-key-mappings*

<Plug>(neocomplcache_snippets_expand)		*<Plug>(neocomplcache_snippets_expand)*
		Expands a cursor snippet of plural lines. When there is no
		snippet, jumps to the next placeholder.

		Note: It searches cursor snippet from keyword patterns in the
		first.

<Plug>(neocomplcache_snippets_jump)		*<Plug>(neocomplcache_snippets_jump)*
		Jump to next placeholder. If there is no placeholder, expand a
		multiline cursor snippet.

<Plug>(neocomplcache_snippets_force_expand)	*<Plug>(neocomplcache_snippets_force_expand)*
		Expand a cursor snippet. Does nothing if there is no snippet.

<Plug>(neocomplcache_snippets_force_jump)	*<Plug>(neocomplcache_snippets_force_jump)*
		Jump to next place holder. Do not expand any snippet. When
		you do not want to expand a snippet name, use this keymapping.

<Plug>(neocomplcache_start_unite_snippet)	*<Plug>(neocomplcache_start_unite_snippet)*
		Start unite snippet source.
		Note: This mappings is available in insert mode.

neocomplcache#sources#snippets_complete#expandable()
						*neocomplcache#sources#snippets_complete#expandable()*
		Use this function with imap <expr>. It checks whether cursor
		text is snippets trigger or existing placeholder in current
		buffer. Useful for saving keymappings.
		Return value is
		0 : not found
		1 : cursor text is snippets trigger
		2 : existing placeholder in current buffer
		3 : both found.
>
		imap <expr><C-l> neocomplcache#sources#snippets_complete#expandable() ?
		\ "\<Plug>(neocomplcache_snippets_expand)" : "\<C-n>"
<
neocomplcache#sources#snippets_complete#force_expandable()
						*neocomplcache#sources#snippets_complete#force_expandable()*
		Use this function with imap <expr>. It checks whether cursor
		text is snippets trigger. Useful for saving keymappings.

neocomplcache#sources#snippets_complete#jumpable()
						*neocomplcache#sources#snippets_complete#jumpable()*
		Use this function with imap <expr>. It checks whether cursor
		text is an existing placeholder in current buffer.
		Useful for saving keymappings.

------------------------------------------------------------------------------
FUNCTIONS					*neocomplcache-snippets-complete-functions*

neocomplcache#sources#snippets_complete#get_snippets_dir()
						*neocomplcache#sources#snippets_complete#get_snippets_dir()*
		Gets snippet directories. This directories contain runtime
		snippets directories and |g:neocomplcache_snippets_dir|
		directories.

==============================================================================
EXAMPLES					*neocomplcache-snippets-complete-examples*
>
	" Plugin key-mappings.
	imap <C-k>     <Plug>(neocomplcache_snippets_expand)
	smap <C-k>     <Plug>(neocomplcache_snippets_expand)

	" SuperTab like snippets behavior.
	"imap <expr><TAB> neocomplcache#sources#snippets_complete#expandable() ?
	" \ "\<Plug>(neocomplcache_snippets_expand)" : pumvisible() ? "\<C-n>" : "\<TAB>"

	" For snippet_complete marker.
	if has('conceal')
	  set conceallevel=2 concealcursor=i
	endif

==============================================================================
SNIPPET SYNTAX					*neocomplcache-snippets-complete-snippet-syntax*

The snippet syntax is similar to |snipMate|.

Example:
>
	snippet     if
	abbr        if endif
	prev_word   '^'
	    if $<1:condition>
	        ${2}
	    endif
<
snippet {snippet_name} syntax is the snippet name.
abbr {abbr_name} is the completion abbrevation (same to completion "abbr" key).
prev_word '^' means this snippet is enabled only in line head.

By the way, it is warned that the snippet name was already defined by other
snippet file.  If you want to overwrite it explicitly, please use:
>
	delete snippets_name
<
and redefine the snippet.

When including external files or other snippet file's snippets are overwrited,
you will not be warned.

Snippet include feature is available.
>
	include c.snip
<
Eval snippet feature is available.
>
	snippet     hoge
	prev_word   '^'
	    `expand("%")`
<
If you use |:NeoComplCacheEditSnippets| command for easy snippet editing, the
file will be loaded automatically when you save the file.

Neocomplcache doesn't map snippet-expand key by default. If you want to use
snippet feature, you can define below mappings in your .vimrc:
>
	imap <C-l>    <Plug>(neocomplcache_snippets_expand)
	smap <C-l>    <Plug>(neocomplcache_snippets_expand)
<

Placeholder feature is available.
>
	snippet     if
	abbr        if endif
	prev_word   '^'
	    if ${1:condition}
	        ${2}
	    endif
<
'_' snippet feature is supported. '_' snippet is loaded in all filetypes.
And neocomplcache can load snipMate snippets.

Alias feature is supported. Separator is ' ' or ','.
>
	alias hoge hogera hogehoge
<
Synchronized placeholder feature is supported.  $1 is synchronized to ${1}.
When you jump next, it is synchlonized. $0 is last jump placeholder.

The placeholder value can't contain new lines. Below snippet is illegal:
>
	snippet test
		${1:constructor: (${2:args\}) ->
			${3:# do smth}}
<
Multi snippet feature is supported in snipMate.
neocomplcache substitutes trigger and descriptions spaces to '_'.
>
	snippet trigger description1
		hoge
	snippet trigger description2
		piyo
<
You choose snippet <C-n> or <C-p> and expand it with
|<Plug>(neocomplcache_snippets_expand)| key-mappings.

Nested placeholder feature is supported.
But must escape inner '}'. '\' is eacape sequence.
>
	snippet div
	<div ${1:id="${2:someid\}"}>${3}</div>${4}
<
If you use hard tab for indentation in snippet file, neocomplcache will use
'shiftwidth' instead of Vim indent plugin. This feature is useful while some
languages' indent files can not work very well (e.g.: PHP, Python).
>
	snippet if
		if (${1:/* condition */}) {
			${2:// code...}
		}
<

		Normally used in |<Plug>(neocomplcache_start_unite_snippet)| mappings.
		But you can execute it by ":Unite snippet".
		You can edit snippet file in "edit" action.
		Examples:
>
		imap <C-s>  <Plug>(neocomplcache_start_unite_snippet)
<
