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 *:NeoComplCacheCachingSnippets* Note: |:NeoComplCacheCachingSnippets| is obsolete name.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 Note: |:NeoComplCacheEditSnippets| is obsolete name.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 *:NeoComplCacheEditRuntimeSnippets* Note: |:NeoComplCacheEditRuntimeSnippets| is obsolete name.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. Note: Neosnippet loads filetype snippet files. If you are editing "vim" filetypes files, neosnippet wll load "vim.snip*" and "vim_*.snip*" and "vim/**/*.snip" snippet files. *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, all runtime snippets won't be loaded in the specified filetype. 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(all runtime snippets are disabled). 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* (neosnippet_expand_or_jump) *(neosnippet_expand_or_jump)* s_(neosnippet_expand_or_jump) *s_(neosnippet_expand_or_jump)* Expands a cursor snippet of plural lines. When there is no snippet, jumps to the next placeholder. *(neocomplcache_snippets_expand)* Note: |(neocomplcache_snippets_expand)| is obsolete name. (neosnippet_jump_or_expand) *(neosnippet_jump_or_expand)* s_(neosnippet_jump_or_expand) *s_(neosnippet_jump_or_expand)* Jump to next placeholder. If there is no placeholder, expand a multiline cursor snippet. *(neocomplcache_snippets_jump)* Note: |(neocomplcache_snippets_jump)| is obsolete name. (neosnippet_expand) *(neosnippet_expand)* s_(neosnippet_expand) *s_(neosnippet_expand)* Expand a cursor snippet. Does nothing if there is no snippet. *(neocomplcache_snippets_force_expand)* Note: |(neocomplcache_snippets_force_expand)| is obsolete name. (neosnippet_jump) *(neosnippet_jump)* s_(neosnippet_jump) *s_(neosnippet_jump)* Jump to next place holder. Do not expand any snippet. When you do not want to expand a snippet name, use this keymapping. *(neocomplcache_snippets_force_jump)* Note: |(neocomplcache_snippets_force_jump)| is obsolete name. i_(neosnippet_start_unite_snippet) *i_(neosnippet_start_unite_snippet)* Start unite snippet source. You can expand a snippet by unite interface. Note: |unite.vim| is required. *(neocomplcache_start_unite_snippet)* Note: |(neocomplcache_start_unite_snippet)| is obsolete name. x_(neosnippet_expand_target) *x_(neosnippet_expand_target)* Expand inputted trigger by selected target text. neosnippet#expandable() *neosnippet#expandable()* Use this function with imap . 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 > imap neosnippet#expandable() ? \ "\(neosnippet_expand_or_jump)" : "\" < *neocomplcache#sources#snippets_complete#expandable()* *neocomplcache#sources#snippets_complete#force_expandable()* Note: |neocomplcache#sources#snippets_complete#expandable()| and |neocomplcache#sources#snippets_complete#force_expandable()| is obsolete name. neosnippet#jumpable() *neosnippet#jumpable()* Use this function with imap . It checks whether cursor text is an existing placeholder in current buffer. Useful for saving keymappings. *neocomplcache#sources#snippets_complete#jumpable()* Note: |neocomplcache#sources#snippets_complete#jumpable()| is obsolete name. ------------------------------------------------------------------------------ FUNCTIONS *neosnippet-functions* neosnippet#get_snippets_directory() *neosnippet#get_snippets_directory()* Gets snippet directories. This directories contain runtime snippets directories and |g:neosnippet#snippets_directory| directories. *neocomplcache#sources#snippets_complete#get_snippets_dir()* Note: |neocomplcache#sources#snippets_complete#get_snippets_dir()| is obsolete name. ============================================================================== EXAMPLES *neosnippet-examples* > " Plugin key-mappings. imap (neosnippet_expand_or_jump) smap (neosnippet_expand_or_jump) xmap (neosnippet_expand_target) " SuperTab like snippets behavior. "imap neosnippet#expandable() ? " \ "\(neosnippet_expand_or_jump)" " \: pumvisible() ? "\" : "\" "smap neosnippet#expandable() ? " \ "\(neosnippet_expand_or_jump)" " \: "\" " For snippet_complete marker. if has('conceal') set conceallevel=2 concealcursor=i endif < ============================================================================== SNIPPET SYNTAX *neosnippet-snippet-syntax* The snippet syntax is similar to |snipMate|. Example: > snippet if abbr if endif options head if ${1:condition} ${2} endif < snippet {snippet_name} syntax is the snippet name. abbr {abbr_name} is the completion abbrevation (same to completion "abbr" key). "options head" means this snippet is enabled only in line head. Note: prev_word '^' is duplicated keyword. By the way, it is warned that the snippet name was already defined by other snippet file. If you want to overwrite it explicitly, please use: > delete snippets_name < and redefine the snippet. When including external files or other snippet file's snippets are overwrited, you will not be warned. Snippet include feature is available. > include c.snip < If you want to include a whole filetype directory snippets. > include javascript/* < Eval snippet feature is available. > snippet hoge options head `expand("%")` < Note: You want to use backticks in snippet, you must escape backticks. > snippet code abbr code \`${1}\`${2} < 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 (neosnippet_expand_or_jump) smap (neosnippet_expand_or_jump) < Placeholder feature is available. The string after ":" is default value. > snippet if abbr if endif options head if ${1:condition} ${2} endif < Commented placeholder feature is available. If the default value starts with "#:", neosnippet will the delete default value when jump to next placeholder. > snippet if abbr if endif options head if ${1:#:condition} ${2} endif < Targetted placeholder feature is available. If the default value starts with "TARGET:", neosnippet will insert selected text in |(neosnippet_expand_target)|. > snippet if abbr if endif options head if ${1:#:condition} ${2:TARGET} endif < Note: To contain "}" character in default value, you must escape "}". > snippet test ${1:escape \} value} < '_' (global) snippet feature is available. Neosnippet loads '_' snippet for all filetypes. Neosnippet can load snipMate snippets as well. Alias feature is available. The separator is either ' ' or ','. > alias hoge hogera hogehoge < Synchronized placeholder feature is supported. $1 is synchronized to ${1}. When you jump next, it will be synchronized. $0 will be the final jump placeholder. The placeholder value can't contain new lines. The snippet below isn't valid: > snippet test ${1:constructor: (${2:args\}) -> ${3:# do smth}} < Multi snippet feature in snipMate is available. Neosnippet substitutes trigger and descriptions spaces to '_'. > snippet trigger description1 hoge snippet trigger description2 piyo < Choose snippets using or and expand it with |(neosnippet_expand_or_jump)| key-mappings. Nested placeholder feature is available, But you must escape inner "}". "\" is the eacape sequence. > snippet div
${3}
${4} < You must escape "}" twice in following case. > snippet catch options head catch ${1:/${2:pattern: empty, E484, Vim(cmdname):{errmsg\\}\}/} < Because ${1:} substitutes the pattern to "/${2:pattern: empty, E484, Vim(cmdname):{errmsg\}}" and ${2:} substitutes the pattern to "pattern: empty, E484, Vim(cmdname):{errmsg}" If you use hard-tab for indentation in snippet file, neosnippet will use 'shiftwidth' instead of Vim indent plugin. This feature is useful while some languages' indent files can not work very well (e.g.: PHP, Python). > snippet if if (${1:/* condition */}) { ${2:// code...} } < "options word" means this snippet is expanded by word boundary. Note: To complete the trigger in snippets_complete, it must be word(digits or alphabet characters or "_") characters. > snippet date options word `strftime("%d %b %Y")` < ============================================================================== UNITE SOURCES *neosnippet-unite-sources* *neosnippet-unite-source-snippet* snippet The candidates are neosnippet snippets. The kinds are "snippet". Normally used in |(neosnippet_start_unite_snippet)| mappings. But you can execute it by ":Unite snippet". You can edit snippet file in "edit" action. Examples: > imap (neosnippet_start_unite_snippet) < source actions snippet *neosnippet-unite-action-snippet* expand Expand snippet (default action) edit Edit snippet preview View snippet definition ============================================================================== CHANGELOG *neosnippet-changelog* 2012-10-30 - Implemented commented placeholder. - Improved python snippets. - Fixed for alias. - Implemented targetted placeholder. - Improved documentation. 2012-10-29 - Improved parse of snippets file. - Improved syntax of markers. - Improved clear select mode mappings. - Added get_selected_text(). 2012-10-28 - Improved snipMate compatibility. - Improved expand behavior. - Improved filter behavior. 2012-10-27 - Fixed for :SnippetEdit. - Improved g:neosnippet#disable_select_mode_mappings behavior. 2012-10-26 - Improved javascript snippet file. 2012-10-25 - Deleted sandbox execution. 2012-10-23 - Improved neosnippet#util#expand(). 2012-10-21 - Added options head. - Added options word. - Improved options word behavior. - Use head instead of prev_word. 2012-10-20 - Improved scala snip. - Added haskell snip. - Added vim/vital snip. 2012-10-19 - Fixed syntax highlight. - Improved documentation. - Search snippets recursively. - Fixed make cache behavior. 2012-10-18 - Fixed s:get_sources_list(). - Added unite__new_candidate action in snippet source. - Fixed menu pattern. 2012-10-17 - Fixed alias problem. - Improved escape placeholder. 2012-10-15 - Improved lua snip. - Improved c++ snip. 2012-10-07 - Improved vim snip. - Improved c snip. 2012-10-06 - Improved indent snippet behavior. - Fixed substitute marker. - Fixed for E749. 2012-10-04 - Refactored snippets filter. - Changed :NeoSnippetEdit behavior. - Added scala snip. - Fixed s:get_cursor_snippet(). - Changed g:neosnippet#disable_runtime_snippets behavior. - Changed prev_word behavior. 2012-10-01 - Deleted neosnippet#force_expandable(). - Improved python snippets. 2012-09-30 - Changed runtime directory. - Vitalized. - Deleted neocomplcache#util functions. - Refactored variables. - Deleted s:get_cursor_keyword_snippet(). - Improved for filetype. - Improved filetype complete. - Improved documentation. - Changed neocomplcache source behavior. - Renamed commands. - Fixed snippet source errors. 2012-09-27 - Ver.3 development is started. - Renamed documentation. - Renamed keymappings. ------------------------------------------------------------------------------ ChangeLog 2.0: 2012-09-27 - Improved add placeholder behavior. - Fixed wrong indentation when 'expandtab'. 2012-09-23 - Fixed substitute tab character. - Improved cursor position. - Fixed column in select mode. - Added lua snip. - Improved javascript snip. - Improved ruby snip. 2012-09-06 - Added neocomplcache__convertable attribute. 2012-08-30 - Changed (neocomplcache_snippets_expand) behavior. 2012-08-27 - Fixed neocomplcache#sources#snippets_complete#force_expandable(). 2012-08-02 - Improved caching snippet files. 2012-06-06 - Added neocomplcache#sources#snippets_complete#get_snippets_dir(). 2012-06-02 - Fixed exapnd indentation. 2012-05-16 - Added ftdetect file. 2012-05-12 - Improved c snip. 2012-05-03 - Released ver.2.0. 2012-04-05 - Fixed nested placeholder problem. 2012-03-23 - Fixed substitute pattern bug. 2012-03-19 - Fixed substitute marker. 2012-03-18 - Fixed for expandtab. 2012-03-17 - Fixed for echodoc. 2012-03-16 - Fixed snippets indentation. 2012-03-15 - Improved search snippet markers behavior. - Don't conceal default codes. 2012-03-14 - Refactored expand snippet behavior. - Fixed expand bug. - Refactored substitute patterns. - Changed marker patterns. 2012-03-08 - Use shiftwidth instead of softabstop. - Fixed plugin indentation problem. 2012-03-07 - Added snippet source. - Fixed snippet source behavior. - Improved snippet source. 2012-03-06 - Improved ftplugin. 2012-03-03 - Added neocomplcache#sources#snippets_complete#force_expandable() and neocomplcache#sources#snippets_complete#jumpable(). 2012-02-25 - Improved split(). 2012-02-24 - Improved a bit. 2012-02-22 - Fixed prev_word behavior. 2012-02-21 - Improved documentation. 2012-02-05 - Fixed variable name. 2012-02-02 - Initial version. - Improved documentation. ============================================================================== vim:tw=78:ts=8:ft=help:norl:noet:fen:fdl=0:noet:
