INTRODUCTION *neosnippet-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 *neosnippet-install*
1: Extract the file and put files in your Vim directory
(usually ~/.vim/ or Program Files/Vim/vimfiles on Windows).
Note: If you want to complete snippets, you must install neocomplcache
(https://github.com/Shougo/neocomplcache).
==============================================================================
INTERFACE *neosnippet-interface*
------------------------------------------------------------------------------
COMMANDS *neosnippet-commands*
:NeoSnippetMakeCache [filetype]
*:NeoSnippetMakeCache*
Makes cache of [filetype] snippets. It automatically selects
current buffer's filetype unless you specify [filetype].
*:NeoComplCacheCachingSnippets*
Note: |:NeoComplCacheCachingSnippets| is obsolete name.
:NeoSnippetEdit [{options}] [filetype]
*:NeoSnippetEdit*
Opens [filetype] snippets to edit. It automatically selects
current buffer's filetype unless you specify [filetype].
If [filetype] snippets has a directory, it automatically edit
"[filetype].snip" in [filetype] subdirectory.
It edits a snippet file in |g:neosnippet#snippets_directory|
with precedence.
Re-make cache will be done automatically when you save the
file.
*:NeoComplCacheEditSnippets*
{options} are options for the command. You may give the
following parameters for a option; you must escape with "\"
when it contains spaces.
*neosnippet-edit-options-vertical*
-vertical
Splits window vertically.
*neosnippet-edit-options-horizontal*
-horizontal
Splits window horizontally.
The behavior is undefined when both options are defined.
*neosnippet-edit-options-direction*
-direction={direction}
Defines split position rule. The default value is "belowleft".
*neosnippet-edit-options-split*
-split
Split buffer.
*neosnippet-edit-options-runtime*
-runtime
Edit runtime snippets instead of user snippets.
Note: |:NeoComplCacheEditSnippets| is obsolete name.
:NeoComplCacheEdit -runtime [filetype]
It edits a runtime snippet file with neosnippet.
Re-make cache will be done automatically when you save the
file.
*:NeoComplCacheEditRuntimeSnippets*
Note: |:NeoComplCacheEditRuntimeSnippets| is obsolete name.
------------------------------------------------------------------------------
VARIABLES *neosnippet-variables*
g:neosnippet#snippets_directory *g:neosnippet#snippets_directory*
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.
*g:neocomplcache_snippets_dir*
Note: |g:neocomplcache_snippets_dir| is obsolete name.
This variable doesn't exist unless you declare it.
g:neosnippet#disable_select_mode_mappings
*g:neosnippet#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.
*g:neocomplcache_disable_select_mode_mappings*
Note: |g:neocomplcache_disable_select_mode_mappings| is
obsolete name.
Default value is 1.
g:neosnippet#disable_runtime_snippets
*g:neosnippet#disable_runtime_snippets*
This is dictionary variable. The key is filetype. If the
value is 1, runtime snippets won't be loaded.
If the key is "_", it will be used for default filetype.
This variable is useful to avoid snippets conflictions.
Note: It must be set in .vimrc.
For example:
>
let g:neosnippet#disable_runtime_snippets = {
\ 'c' : 1, 'cpp' : 1,
\ }
" Like g:neocomplcache_snippets_disable_runtime_snippets
" behavior.
let g:neosnippet#disable_runtime_snippets = {
\ '_' : 1,
\ }
<
*g:neocomplcache_snippets_disable_runtime_snippets*
Note: |g:neocomplcache_snippets_disable_runtime_snippets| is
obsolete name.
Default value is {}.
------------------------------------------------------------------------------
KEY MAPPINGS *neosnippet-key-mappings*
<Plug>(neosnippet_expand_or_jump)
*<Plug>(neosnippet_expand_or_jump)*

snippet, jumps to the next placeholder.
*<Plug>(neocomplcache_snippets_expand)*
Note: |<Plug>(neocomplcache_snippets_expand)| is obsolete
name.

Note: |<Plug>(neocomplcache_snippets_jump)| is obsolete
name.
<Plug>(neosnippet_expand)
*<Plug>(neosnippet_expand)*
Expand a cursor snippet. Does nothing if there is no snippet.
*<Plug>(neocomplcache_snippets_force_expand)*
Note: |<Plug>(neocomplcache_snippets_force_expand)| is
obsolete name.
<Plug>(neosnippet_jump)
*<Plug>(neosnippet_jump)*

you do not want to expand a snippet name, use this keymapping.

Note: |<Plug>(neocomplcache_snippets_force_jump)| is
obsolete name.
i_<Plug>(neosnippet_start_unite_snippet)
*i_<Plug>(neosnippet_start_unite_snippet)*

interface.
Note: |unite.vim| is required.
*<Plug>(neocomplcache_start_unite_snippet)*
Note: |<Plug>(neocomplcache_start_unite_snippet)| is obsolete
name.
neosnippet#expandable()
*neosnippet#expandable()*
Use this function with imap <expr>. It checks whether cursor
text is a snippet trigger or a placeholder exists in the
current buffer. It's useful for saving keymappings.
Return value is not just a boolean but either
0: not found
1: cursor text is a snippet trigger
2: a placeholder exists in the current buffer
3: both found

Use this function with imap <expr>. It checks whether cursor
text is an existing placeholder in current buffer.
Useful for saving keymappings.

FUNCTIONS *neosnippet-functions*
neosnippet#get_snippets_directory()
*neosnippet#get_snippets_directory()*

==============================================================================
SNIPPET SYNTAX *neosnippet-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 |:NeoSnippetEdit| command for easy snippet editing, the file will
be loaded automatically when you save the file.
Neosnippet 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>(neosnippet_expand_or_jump)
smap <C-l> <Plug>(neosnippet_expand_or_jump)
<
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 neosnippet 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.
neosnippet 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>(neosnippet_expand_or_jump)| 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, neosnippet 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...}
}
<
==============================================================================
UNITE SOURCES *neosnippet-unite-sources*
*neosnippet-unite-source-snippet*
snippet
The candidates are neosnippet snippets. The kinds are
"snippet". Normally used in
|<Plug>(neosnippet_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>(neosnippet_start_unite_snippet)
<
source actions
snippet *neosnippet-unite-action-snippet*
expand Expand snippet (default action)
edit Edit snippet
preview View snippet definition
