It provides a keyword completion system by maintaining a keyword cache of the current buffer. The neocomplete framework can be customized easily and has a lot more features than Vim's standard completion. Note: neocomplete may consume more memory than other plugins do. Improvements in neocomplete in comparison to |neocomplcache|: 1. Real fuzzy match behavior like |YouCompleteMe| by default. 2. Refactored source interface. 3. Removed legacy interface. 4. Requires |if_lua|. 5. Optimized completion speed. 6. Changed source names. 7. Changed variable names. 8. Added new features. ============================================================================== INSTALL *neocomplete-install* Install prerequisites In order to use neocomplete, the following prerequisites have to be met: 1. Vim build with the |if_lua| feature 2. Vim version 7.3.885 or above The following sections describe where to get a Vim version, neocomplete works with, for your operating system. On Windows: For 32bit http://files.kaoriya.net/goto/vim73w32 For 32bit (alternative) http://tuxproject.de/projects/vim/ http://wyw.dcweb.cn/#download For 64bit http://files.kaoriya.net/goto/vim73w64 On Mac: You can get |if_lua| enabled MacVim versions here: https://github.com/zhaocai/macvim http://code.google.com/p/macvim-kaoriya/ Or install it with homebrew: > brew install macvim --with-cscope --with-lua --HEAD < On Linux: As almost all Vim packages offered by distributions are too old, you should build Vim manually using gnu make and enable |if_lua| in the configuration step. The following steps show you the general process on how to build Vim: 1. Get the source package 2. Unpack the sources 3. Configure the package (./configure). This step is essential to enable the Vim features you like to use. 4. Build the package with gnu make 5. Install the package using your distributions package manager You can find detailed information on ho to configure and build Vim from source under following link: http://vim.wikia.com/wiki/Building_Vim. Or follow the guide on: https://github.com/Valloric/YouCompleteMe/wiki/Building-Vim-from-source Install the plugin After you have installed the right version of Vim, you can go on to install the neocomplete plugin. You can do this in a more old fashioned, manual way or use a plugin manager like pathogen, vundle, neobundle. The second approach is the recommended installation method. Manual: 1. Get the plugin package 2. Extract the files and put them in your Vim directory (usually ~/.vim/ or Program Files/Vim/vimfiles on Windows). 3. Execute |:NeoCompleteEnable| command or set following variable in your vimrc > let g:neocomplete#enable_at_startup = 1 Package manager: For instructions on how to set up a Vim package manager see the documentation of the package manager of your choice. For example after installing neobundle you can install the neocomplete plugin with the following steps: 1. Let the plugin manger know about the package (.vimrc) > NeoBundle 'Shougo/neocomplete.vim' < 2. Install the plugin with the install command > :NeoBundleInstall < *neocomplete-migration* In case you are planing to move from neocomplcache to neocomplete there is a wiki page that offers a migration guide. https://github.com/Shougo/neocomplete.vim/wiki/neocomplete-migration-guide *neocomplete-RECOMMENDATION* *neocomplete-asynchronous* If you have installed the |vimproc| plugin, neocomplete creates the caches asynchronously. You can find vimproc at: http://github.com/Shougo/vimproc. The vimproc plugin needs compilation before you can use it. You can find further information in the vimproc documentation. *neocomplete-snippets* If you would like to use the snippet feature with neocomplete, you need to install the neosnippet plugin (https://github.com/Shougo/neosnippet.vim) or UltiSnips (https://github.com/SirVer/ultisnips). *neocomplete-context-filetype* If you would like to use the context filetype feature, you need to install the context_filetype.vim plugin which you can find under the following repository: https://github.com/Shougo/context_filetype.vim *neocomplete-include* If you want to complete the candidates from include files or include files candidates, you need to install the neoinclude plugin (https://github.com/Shougo/neoinclude.vim). *neocomplete-syntax* If you want to complete the candidates from syntax files, you need to install the neco-syntax plugin (https://github.com/Shougo/neco-syntax). *neocomplete-neopairs* If you want to insert the parentheses pairs automatically, you need to install the neopairs plugin (https://github.com/Shougo/neopairs.vim). ============================================================================== INTERFACE *neocomplete-interface* ------------------------------------------------------------------------------ COMMANDS *neocomplete-commands* :NeoCompleteEnable *:NeoCompleteEnable* Validate neocomplete and initialize it. Warning: Existing cache disappears. :NeoCompleteDisable *:NeoCompleteDisable* Invalidate neocomplete and clean it up. :NeoCompleteToggle *:NeoCompleteToggle* Change the lock/unlock state of neocomplete. While neocomplete is in locking, you cannot use automatic completions. Note: This command also enables neocomplete if it is disabled. :NeoCompleteLock *:NeoCompleteLock* Lock neocomplete. While neocomplete is in locking, you cannot use automatic completions but can use manual completions. The lock status is local to each buffer. Note: This command is disabled when neocomplete is disabled. :NeoCompleteUnlock *:NeoCompleteUnlock* Unlock neocomplete. Note: This command is disabled when neocomplete is disabled. *:NeoCompleteAutoCompletionLength* :NeoCompleteAutoCompletionLength {length} Change the length of chars to start automatic completion to {length}. Note: The length value is local to each buffer. :NeoCompleteClean *:NeoCompleteClean* Clean files in |g:neocomplete#data_directory|. :NeoCompleteSetFileType [filetype] *:NeoCompleteSetFileType* Change the filetype to [filetype] in the current buffer. This filetype is only used by neocomplete, so syntax highlighting and etc stay same. Note: You can get the current filetype by |neocomplete#get_context_filetype()| SOURCES COMMANDS *neocomplete-sources-COMMANDS* :NeoCompleteBufferMakeCache [bufname] *:NeoCompleteBufferMakeCache* Make a cache based on the buffer with the name [bufname]. The command selects the current buffer when you omit [bufname]. If [bufname] is not loaded, neocomplete will open [bufname] automatically. Note: It may take time considerably for the big buffer. *:NeoCompleteDictionaryMakeCache* :NeoCompleteDictionaryMakeCache [filetype] Make a cache from a dictionary file with [filetype]. Selects the filetype of the current buffer if [filetype] is omitted. :NeoCompleteTagMakeCache *:NeoCompleteTagMakeCache* Make a cache from a tags file in current buffer. :NeoCompleteMemberMakeCache *:NeoCompleteMemberMakeCache* Make a member cache based in current buffer. ------------------------------------------------------------------------------ VARIABLES *neocomplete-variables* *g:neocomplete#enable_at_startup* g:neocomplete#enable_at_startup neocomplete gets started automatically when Vim starts if this value is 1. With the default value 0, you cannot use neocomplete unless you start it manually. Note: This option has to be set in your .vimrc or _vimrc. NOT IN the .gvimrc nor _gvimrc! g:neocomplete#max_list *g:neocomplete#max_list* This variable controls the number of candidates displayed in a pop-up menu. If the list of candidates exceeds the limit, not all candidates will show up. Default value is 100. *g:neocomplete#max_keyword_width* g:neocomplete#max_keyword_width This variable controls the indication width of a candidate displayed in a pop-up menu. If the keyword length exceeds the length it will be cut down properly. Default value is 80. *g:neocomplete#auto_completion_start_length* g:neocomplete#auto_completion_start_length This variable controls the number of the input completion at the time of key input automatically. Note: |g:neocomplete#auto_completion_start_length| is used for "keyword" kind source only. Please refer to |neocomplete-source-attribute-min_pattern_length|. Default value is 2. *g:neocomplete#manual_completion_start_length* g:neocomplete#manual_completion_start_length This variable controls the number of the input completion at the time of manual completion. It is convenient when you reduce this value, but may get heavy when you deleted a letter in or at popup indication time. Default value is 0. *g:neocomplete#min_keyword_length* g:neocomplete#min_keyword_length In a buffer or dictionary files, this variable controls length of keyword becoming the targets of the completion at the minimum. Default value is 4. *g:neocomplete#enable_ignore_case* g:neocomplete#enable_ignore_case When neocomplete looks for candidate completion, this variable controls whether neocomplete ignores the upper- and lowercase. If it is 1, neocomplete ignores case. Default value is 'ignorecase'. *g:neocomplete#enable_smart_case* g:neocomplete#enable_smart_case When a capital letter is included in input, neocomplete does not ignore the upper- and lowercase. Default value is 'infercase'. *g:neocomplete#enable_camel_case* g:neocomplete#enable_camel_case When a capital letter is matched with the uppercase, but a lower letter is matched with the upper- and lowercase. Ex: "foB" is matched with "FooBar" not "foobar". Note: This feature is only available in |neocomplete-filter-matcher_fuzzy|. Default value is 0. *g:neocomplete#disable_auto_complete* g:neocomplete#disable_auto_complete This variable controls whether you invalidate automatic completion. If it is 1, automatic completion becomes invalid, but can use the manual completion by |neocomplete#start_manual_complete()|. Default value is 0. *g:neocomplete#auto_complete_delay* g:neocomplete#auto_complete_delay It is the auto completion delay time after your input. The unit is ms. Note: It requires |+timers| feature. Default value is 50. *g:neocomplete#enable_auto_select* g:neocomplete#enable_auto_select When neocomplete displays candidates, this option controls whether neocomplete selects the first candidate automatically. If you enable this option, neocomplete's completion behavior is like |AutoComplPop|. Note: If you want to enable the feature in |g:neocomplete#force_omni_input_patterns|, you need Vim 7.4.775 or above. Default value is 0. *g:neocomplete#enable_auto_delimiter* g:neocomplete#enable_auto_delimiter This option controls whether neocomplete insert delimiter automatically. For example, / (filenames) or # (Vim scripts.) Default value is 0. *g:neocomplete#enable_fuzzy_completion* g:neocomplete#enable_fuzzy_completion When you input one character, this variable controls whether neocomplete takes an ambiguous searching as an end of the words in it. For example, neocomplete comes to match it with "public_html" or "PublicHtml" when you input it with "puh". Note: The first letter must be matched. Default value is 1. *g:neocomplete#enable_refresh_always* g:neocomplete#enable_refresh_always Neocomplete refreshes the candidates automatically if this value is 1. Note: It increases the screen flicker. Default value is 0. *g:neocomplete#enable_multibyte_completion* g:neocomplete#enable_multibyte_completion If it is non-0, neocomplete can complete multibyte characters. Note: This feature may conflict Input Method in Unix systems. Note: To use multibyte completion, you must change |g:neocomplete#keyword_patterns| variable. Default value is 0. *g:neocomplete#lock_buffer_name_pattern* g:neocomplete#lock_buffer_name_pattern This variable sets a pattern of the buffer name. If matched it, neocomplete does not complete automatically. When it is an empty character string, neocomplete will ignore it. Default value is ''. g:neocomplete#lock_iminsert *g:neocomplete#lock_iminsert* If this variable is non-zero, neocomplete locks when 'iminsert' is non-zero. Default value is 0. g:neocomplete#data_directory *g:neocomplete#data_directory* This variable appoints the directory that neocomplete begins to write a file at one time. When there is not the directory which appointed here, it is made. For example, buffer.vim stores cache of the keyword in this 'buffer_cache' sub directory. Default value is "$XDG_CACHE_HOME/neocomplete" or expand("~/.cache/neocomplete"); the absolute path of it. *g:neocomplete#keyword_patterns* g:neocomplete#keyword_patterns This dictionary records keyword patterns to completion. This is appointed in regular expression every file type. If the key is "_" or "default", it is used for default pattern. Because it is complicated, refer to neocomplete#init#_variables() in autoload/neocomplete/init.vim for the initial value. > " Examples: if !exists('g:neocomplete#keyword_patterns') let g:neocomplete#keyword_patterns = {} endif let g:neocomplete#keyword_patterns._ = '\h\w*' < *g:neocomplete#force_omni_input_patterns* g:neocomplete#force_omni_input_patterns This dictionary records keyword patterns to Omni completion. This is appointed in regular expression every file type. If this pattern is not defined or empty pattern, neocomplete does not call 'omnifunc'. Note: If it is a set, neocomplete will call 'omnifunc' directly. So almost neocomplete features are disabled. But all Omni completion works instead of |g:neocomplete#sources#omni#input_patterns|. > if !exists('g:neocomplete#force_omni_input_patterns') let g:neocomplete#force_omni_input_patterns = {} endif let g:neocomplete#force_omni_input_patterns.ruby = \ '[^. *\t]\.\w*\|\h\w*::' < Because it is complicated, refer to neocomplete#init#_variables() in autoload/neocomplete/init.vim for the initial value. *g:neocomplete#text_mode_filetypes* g:neocomplete#text_mode_filetypes It is a dictionary to define text mode filetypes. The dictionary's key is filetype and value is number. If the value is non-zero, this filetype is text mode. In text mode, neocomplete supports word conversion to write English. If the key is "_" and the value is non-zero, all filetypes are text mode. For example, if you input "Fo", neocomplete will convert candidate "foo" to "Foo". If you input "foo", neocomplete will convert candidate "FooBar" to "foobar". If you input "FO", neocomplete will convert candidate "foo" to "FOO". Note: Text mode conversion is only used for "foobar" or "Foobar" or "FOOBAR" words. Not "fooBar" or "FooBar". Because it is complicated, refer to neocomplete#init#_variables() in autoload/neocomplete/init.vim for the initial value. *g:neocomplete#delimiter_patterns* g:neocomplete#delimiter_patterns This variable appoints a delimiter pattern to smart complete a function. This is appointed in string list every file type. Note: This string is not regular expression. > " Examples: if !exists('g:neocomplete#delimiter_patterns') let g:neocomplete#delimiter_patterns= {} endif let g:neocomplete#delimiter_patterns.vim = ['#'] let g:neocomplete#delimiter_patterns.cpp = ['::'] < Because it is complicated, refer to neocomplete#init#_variables() in autoload/neocomplete/init.vim for the initial value. g:neocomplete#sources *g:neocomplete#sources* It is a dictionary to decide use source names. The key is filetype and the value is source names list. If the key is "_", the value will be used for default filetypes. For example, you can disable some sources in C++ filetype. If the value is "_", it will load all sources. Default value is {}. > " Examples: if !exists('g:neocomplete#sources') let g:neocomplete#sources = {} endif let g:neocomplete#sources._ = ['buffer'] let g:neocomplete#sources.cpp = ['buffer', 'dictionary'] < b:neocomplete_sources *b:neocomplete_sources* It is a list to decide use source names in buffer local. > " Examples: " In cmdwin, only use vim source. autocmd CmdwinEnter * let b:neocomplete_sources = ['vim'] < *g:neocomplete#release_cache_time* g:neocomplete#release_cache_time This variable defines time of automatic released cache by a second unit. Default value is 900. *g:neocomplete#tags_filter_patterns* g:neocomplete#tags_filter_patterns This dictionary records a pattern to filter a candidate in the tag completion. For example, it can exclude a candidate beginning in _ in file type of C/C++. Because it is complicated, refer to neocomplete#init#_variables() in autoload/neocomplete/init.vim for the initial value. g:neocomplete#use_vimproc *g:neocomplete#use_vimproc* This variable is non 0, neocomplete uses |vimproc|. Note: If this variable is non 0, neocomplete will make cache asynchronously. Default value is vimproc auto detection result. *g:neocomplete#skip_auto_completion_time* g:neocomplete#skip_auto_completion_time It is a string for skip auto completion. If completion time is higher than it, neocomplete will skip auto completion. If it is "", the skip feature will be disabled. Default value is "0.3". {only available when compiled with the |+reltime| feature} *g:neocomplete#enable_auto_close_preview* g:neocomplete#enable_auto_close_preview If it is non-zero, neocomplete will close preview window automatically. Default value is 0. *g:neocomplete#fallback_mappings* g:neocomplete#fallback_mappings Neocomplete fallback mappings. If you want to complete keywords by neocomplete and the omnifunc, it is useful. > " Search from neocomplete, omni candidates, vim keywords. let g:neocomplete#fallback_mappings = \ ["\\", "\\"] < Default value is []. SOURCES VARIABLES *neocomplete-sources-variables* *g:neocomplete#sources#buffer#cache_limit_size* g:neocomplete#sources#buffer#cache_limit_size This variable sets file size to make a cache of a file. If open file is bigger than this size, neocomplete does not make a cache. Default value is 500000. *g:neocomplete#sources#buffer#disabled_pattern* g:neocomplete#sources#buffer#disabled_pattern This variable sets a pattern of the buffer file path. If matched it, neocomplete does not save a cache of the buffer. When it is an empty character string, neocomplete will ignore. Default value is ''. *g:neocomplete#sources#buffer#max_keyword_width* g:neocomplete#sources#buffer#max_keyword_width If the keyword length exceeds the length it will be not shown in popup menu. Default value is 80. *g:neocomplete#sources#dictionary#dictionaries* g:neocomplete#sources#dictionary#dictionaries It is a dictionary to connect a dictionary file with file type. The dictionary's key is filetype and comma-separated multiple value is a path to a dictionary file. If the variable is unset or has an empty key, the native 'dictionary' option will be inherited. When you set "text" key, you will appoint dictionary files in text mode. If the key is "_", it is loaded in every filetype. Note: Global 'dictionary' file is not loaded automatically. Default value is {}. *g:neocomplete#sources#member#prefix_patterns* g:neocomplete#sources#member#prefix_patterns This variable appoints a prefix pattern to complete a member in buffer. This is appointed in regular expression every file type. If filetype key is not set, disable member completion. Because it is complicated, refer in autoload/neocomplete/sources/buffer.vim for the initial value. *g:neocomplete#sources#member#input_patterns* g:neocomplete#sources#member#input_patterns This variable appoints a keyword pattern to complete a member in buffer. This is appointed in regular expression every file type. If filetype key is not set, use filetype "_" setting. Because it is complicated, refer in autoload/neocomplete/sources/buffer.vim for the initial value. *g:neocomplete#sources#omni#functions* g:neocomplete#sources#omni#functions This dictionary which appoints omni source call functions. The key is |&filetype|. The value is omnifunc name String or List of omnifunc name String. If |g:neocomplete#sources#omni#functions| [|&filetype|] is undefined, omni source calls 'omnifunc'. If the key is "_", used for all filetypes. Default value is {}. *g:neocomplete#sources#omni#input_patterns* g:neocomplete#sources#omni#input_patterns This dictionary records keyword patterns used in omni source. This is appointed in regular expression every file type or 'omnifunc' name. If this pattern is not defined or empty pattern, neocomplete does not call 'omnifunc'. Note: ruby and php omnifunc are disabled, because they are too slow. Note: Partial omnifunc has problem when neocomplete call (Ex: rubycomplete, jedi.vim, cocoa.vim, and clang_complete.) You should |g:neocomplete#force_omni_input_patterns| instead. Because it is complicated, refer to s:source.initialize() autoload/neocomplete/sources/omni.vim for the initial value. > " Examples: if !exists('g:neocomplete#sources#omni#input_patterns') let g:neocomplete#sources#omni#input_patterns = {} endif let g:neocomplete#sources#omni#input_patterns.php = \ '[^. \t]->\%(\h\w*\)\?\|\h\w*::\%(\h\w*\)\?' let g:neocomplete#sources#omni#input_patterns.c = \ '[^.[:digit:] *\t]\%(\.\|->\)\%(\h\w*\)\?' < *g:neocomplete#sources#tags#cache_limit_size* g:neocomplete#sources#tags#cache_limit_size This variable sets file size to make a cache of a file in tag source. If open file is bigger than this size, neocomplete does not make a tags cache. Default value is 500000. *g:neocomplete#sources#vim#complete_functions* g:neocomplete#sources#vim#complete_functions This dictionary which appoints vim source call function when completes custom and customlist command. The key is command name. The value is function name.

Note: It enables neocomplete. Note: You should call it in |VimEnter| autocmd. User customization for neocomplete must be set before initialization of neocomplete. neocomplete#custom#source({source-name}, {option-name}, {value}) *neocomplete#custom#source()* Set {source-name} source specialized {option-name} to {value}. You may specify multiple sources with separating "," in {source-name}. If {source-name} is "_", sources default option will be change. These options below are available: |neocomplete-source-attributes| Note: User customization for neocomplete must be set before initialization of neocomplete. *neocomplete#custom_source()* neocomplete#custom_source() is used for compatibility. *neocomplete#get_context_filetype()* neocomplete#get_context_filetype() Get current context filetype of the cursor. This is smarter than 'filetype' about handling nested filetypes. Note: To enable context filetype feature, you must install context_filetype.vim. https://github.com/Shougo/context_filetype.vim For example html filetype has javascript inside. Say, you have a buffer which content is below with filetype is html. > < At the line 1 and 3, neocomplete#get_context_filetype() is "html" and at the line 2 it's "javascript", while at any lines 'filetype' is "html". *neocomplete#disable_default_dictionary()* neocomplete#disable_default_dictionary({variable-name}) Disable default {variable-name} dictionary initialization. Note: It must be called in .vimrc. *neocomplete#get_default_matchers()* neocomplete#get_default_matchers() Get default matchers in current buffer. *neocomplete#set_default_matchers()* neocomplete#set_default_matchers({names}) Chang default matchers in current buffer. > call neocomplete#set_default_matchers('matcher_head') < ------------------------------------------------------------------------------ KEY MAPPINGS *neocomplete-key-mappings* *neocomplete#start_manual_complete()* neocomplete#start_manual_complete([{sources}]) Use this function on inoremap . The keymapping call the completion of neocomplete. When you rearrange the completion of the Vim standard, you use it. If you give {sources} argument, neocomplete call {sources}. {sources} is name of source or list of sources name. > inoremap neocomplete#start_manual_complete() < *neocomplete#close_popup()* neocomplete#close_popup() Insert candidate and close popup menu for neocomplete. Note: It is deprecated function. You should use "\" character instead. *neocomplete#cancel_popup()* neocomplete#cancel_popup() Cancel completion menu for neocomplete. Note: It is deprecated function. You should use "\" character instead. *neocomplete#smart_close_popup()* neocomplete#smart_close_popup() Insert candidate and re-generate popup menu for neocomplete. Unlike |neocomplete#close_popup()|, this function changes behavior by |g:neocomplete#enable_auto_select| smart. Note: This mapping is conflicted with |SuperTab| or |endwise| plugins. Note: This key mapping is for or keymappings. You should not use it for . *neocomplete#undo_completion()* neocomplete#undo_completion() Use this function on inoremap to undo inputted candidate. Because there is not mechanism to cancel candidate in Vim, it will be convenient when it inflects. > inoremap neocomplete#undo_completion() < *neocomplete#complete_common_string()* neocomplete#complete_common_string() Use this function on inoremap to complete common string in candidates.

Because tag is too slow if tag read a big tags file. You should use more convenient include source completion now. dictionary *neocomplete-source-dictionary* This source adds candidates from 'dictionary' or |g:neocomplete#sources#dictionary#dictionaries|. file *neocomplete-source-file* This source collects filename candidates. Note: It is relative path to current buffer directory. omni *neocomplete-source-omni* This source calls 'omnifunc' automatically when cursor text is matched with |g:neocomplete#sources#omni#input_patterns|. If |g:neocomplete_omni_function_list| is defined, neocomplete will give priority it. Note: It supports the fuzzy match using the previous result. suffix of complete candidates in popup menu declaration.

It completes a source file written in Haskell. It requires ghc-mod . neco-vim *neocomplete-sources-neco-vim* https://github.com/Shougo/neco-vim It analyzes context and start Omni completion of Vim script. It does not work other than editing time of Vim script. I created it because neocomplete cannot call |i_CTRL-X_CTRL-V|. Local variable and a script variable, a function and the analysis of the command are implemented now. ============================================================================== FILTERS *neocomplete-filters* To custom candidates, neocomplete uses the filters. There are three kinds of filters are available. "matcher" is to filter candidates by user input. "sorter" is to sort candidates. "converter" is to candidates conversion. Default sources are below. But you can create original filters (cf: |neocomplete-create-filter|) and set them by |neocomplete#custom#source()|. > call neocomplete#custom#source( \ 'buffer', 'converters', []) " Change default matcher. call neocomplete#custom#source('_', 'matchers', \ ['matcher_head', 'matcher_length']) " Change default sorter. call neocomplete#custom#source('_', 'sorters', \ ['sorter_length']) " Disable sort. call neocomplete#custom#source('_', 'sorters', []) " Change default converter. call neocomplete#custom#source('_', 'converters', \ ['converter_remove_overlap', 'converter_remove_last_paren', \ 'converter_delimiter', 'converter_abbr']) < *neocomplete-filter-matcher_default* Default matchers: If |g:neocomplete#enable_fuzzy_completion|: ['matcher_head', 'matcher_length'] Otherwise: ['matcher_fuzzy', 'matcher_length'] You can change it by |neocomplete#set_default_matchers()|. *neocomplete-filter-sorter_default* Default sorters: ['sorter_rank']. *neocomplete-filter-converter_default* Default converters: ['converter_remove_overlap', \ 'converter_delimiter', 'converter_abbr']. *neocomplete-filter-matcher_head* matcher_head Head matching matcher. *neocomplete-filter-matcher_fuzzy* matcher_fuzzy Fuzzy matching matcher. *neocomplete-filter-matcher_length* matcher_length Input keyword length matcher. It removes candidates which is less than input keyword length. *neocomplete-filter-matcher_nothing* matcher_nothing Nothing matcher. It disables the matcher filtering. *neocomplete-filter-sorter_rank* sorter_rank Matched rank order sorter. The higher the matched word is already selected or in current buffer *neocomplete-filter-sorter_length* sorter_length Candidates length order sorter. *neocomplete-filter-sorter_word* sorter_word Candidates word order sorter. *neocomplete-filter-converter_abbr* converter_abbr The converter which abbreviates a candidate's abbr. *neocomplete-filter-converter_disable_abbr* converter_disable_abbr The converter which disables a candidate's abbr. *neocomplete-filter-converter_delimiter* converter_delimiter The converter which abbreviates a candidate's delimiter. (cf: |g:neocomplete#delimiter_patterns|) *neocomplete-filter-converter_remove_overlap* converter_remove_overlap The converter which removes overlapped text in a candidate's word. Note: It removes candidates which is not overlapped (it is in auto completion only). *neocomplete-filter-converter_remove_last_paren* converter_remove_last_paren The converter which removes last parentheses in a candidate's word. It is useful if you use auto closing parentheses plugins. *neocomplete-filter-converter_add_paren* converter_add_paren The converter which adds parentheses in a candidate's word. It is useful if you use |neopairs.vim| or |neosnippet.vim| plugins. ============================================================================== CREATE SOURCE *neocomplete-create-source* In this clause, I comment on a method to make source of neocomplete. The ability of neocomplete will spread by creating source by yourself. The files in autoload/neocomplete/sources are automatically loaded and it calls neocomplete#sources#{source_name}#define() whose return value is the source. Each return value can be a list so you can return an empty list to avoid adding undesirable sources. To add your own sources dynamically, you can use |neocomplete#define_source()|. ------------------------------------------------------------------------------ SOURCE ATTRIBUTES *neocomplete-source-attributes* *neocomplete-source-attribute-name* name String (Required) The name of a source. Allowed characters are: - a-z - 0-9 - _ - / - - (Not head) *neocomplete-source-attribute-kind* kind String (Optional) The kind of the source. It decides the behaviour of the complete position. The following values are available: "manual": The source decides the complete position manually with the "get_complete_position" attribute. See also: |neocomplete-source-attribute-get_complete_position| "keyword": The source decides the complete position with |g:neocomplete#keyword_patterns|. This pattern is also used to filter the candidates. Note that "plugin", "complfunc" and "ftplugin" are old values that are no longer accepted. *neocomplete-source-attribute-filetypes* filetypes Dictionary (Optional) Available filetype dictionary. For example: > let source = { \ 'name' : 'test', \ 'kind' : 'manual', \ 'filetypes' : { 'vim' : 1, 'html' : 1 }, \} < The source is available in vim and html filetypes. If you omit it, this source available in all filetypes. *neocomplete-source-attribute-disabled_filetypes* disabled_filetypes Dictionary (Optional) Not available filetype dictionary. If the key is "_", the source is disabled in all sources. *neocomplete-source-attribute-rank* rank Number (Optional) Source priority. Higher values imply higher priority. If you omit it, it is set below value. Note: It is high priority than match position. If kind attribute is "keyword": 5 If filetype attribute is empty: 10 Otherwise: 100 Example: > " Change vim source default rank value of 300. call neocomplete#custom#source('ultisnips', 'rank', 1000) < *neocomplete-source-attribute-min_pattern_length* min_pattern_length Number (Optional) Required pattern length for completion. If you omit it, it is set to |g:neocomplete#auto_completion_start_length| *neocomplete-source-attribute-input_pattern* input_pattern String (Optional) If it is matched, neocomplete ignores |neocomplete-source-attribute-min_pattern_length|. It is useful for omni function sources. If you omit it, it is set to "". *neocomplete-source-attribute-max_candidates* max_candidates Number (Optional) The maximum number of candidates. This attribute is optional; if it is not given, 0 is used as the default value. This means maximum number is infinity. *neocomplete-source-attribute-keyword_patterns* keyword_patterns Dictionary (Optional) This dictionary changes keyword patterns to completion for specific types. > let keyword_patterns = {} let keyword_patterns.tex = '\\\?\h\w*' call neocomplete#custom#source('dictionary', \ 'keyword_patterns', keyword_patterns) < This attribute is optional; if it is not given, |g:neocomplete#keyword_patterns| is used as the default value. *neocomplete-source-attribute-is_volatile* is_volatile Number (Optional) Whether the source recalculates the candidates everytime the input is changed. This attribute is optional. If it's not given, 0 is set as the default value. In this case, candidates are cached. *neocomplete-source-attribute-disabled* disabled Number (Optional) This attribute is optional. If it's not given, 0 is set as the default value. Otherwise, the source is disabled. *neocomplete-source-attribute-hooks* hooks Dictionary (Optional) You may put hook functions in this dictionary in which the key is the position to hook and the value is the reference to the function to be called. The following hook functions are defined: *neocomplete-source-attribute-hooks-on_init* on_init Called when initializing the source. This function takes {context} as its parameters. *neocomplete-source-attribute-hooks-on_final* on_final Called after executing |:NeoCompleteDisable|. This function takes {context} as its parameters. *neocomplete-source-attribute-hooks-on_post_filter* on_post_filter Called after the filters to narrow down the candidates. This is used to set attributes. This filters is to avoid adversely affecting the performance. This function takes {context} as its parameters. *neocomplete-source-attribute-get_complete_position* get_complete_position Function (Optional) This function takes {context} as its parameter and returns complete position in current line. Here, {context} is the context information when the source is called(|neocomplete-notation-{context}|). If you omit it, neocomplete will use the position using |g:neocomplete#keyword_patterns|. Note: If the source returns candidates which are not matched |g:neocomplete#keyword_patterns|, you must define |neocomplete-source-attribute-get_complete_position|. *neocomplete-source-attribute-gather_candidates* gather_candidates Function (Required) This function is called in gathering candidates. If you enabled fuzzy completion by |g:neocomplete#enable_fuzzy_completion| , this function is called whenever the input string is changed. This function takes {context} as its parameter and returns a list of {candidate}. Here, {context} is the context information when the source is called(|neocomplete-notation-{context}|). {context} *neocomplete-notation-{context}* A dictionary to give context information. The followings are the primary information. The global context information can be acquired by |neocomplete#get_context()|. input (String) The input string of current line. complete_pos (Number) The complete position of current source. complete_str (String) The complete string of current source. source__{name} (Unknown) (Optional) Additional source information. Note: Recommend sources save variables instead of s: variables. ------------------------------------------------------------------------------ CANDIDATE ATTRIBUTES *neocomplete-candidate-attributes* *neocomplete-candidate-attribute-name* word String (Required) The completion word of a candidate. It is used for matching inputs. *neocomplete-candidate-attribute-abbr* abbr String (Optional) The abbreviation of a candidate. It is displayed in popup window.

It is displayed in popup window. *neocomplete-candidate-attribute-menu* menu String (Optional) The menu information of a candidate. It is displayed in popup window. *neocomplete-candidate-attribute-info* info String (Optional) The preview information of a candidate. If 'completeopt' contains "preview", it will be displayed in |preview-window|. *neocomplete-candidate-attribute-rank* rank Number (Optional) The completion priority. CONTEXT *neocomplete-context* ============================================================================== CREATE FILTER *neocomplete-create-filter* The files in autoload/neocomplete/filters are automatically loaded and it calls neocomplete#filters#{filter_name}#define() whose return value is the filter. Each return value can be a list so you can return an empty list to avoid adding undesirable filters. To add your own filters dynamically, you can use |neocomplete#define_filter()|. ------------------------------------------------------------------------------ FILTER ATTRIBUTES *neocomplete-filter-attributes* *neocomplete-filter-attribute-name* name String (Required) The filter name. *neocomplete-filter-attribute-filter* filter Function (Required) The filter function. This function takes {context} as its parameter and returns a list of {candidate}. The specification of the parameters and the returned value is same as |neocomplete-source-attribute-gather_candidates|. *neocomplete-filter-attribute-description* description String (Optional) The filter description string. ============================================================================== UNITE SOURCES *neocomplete-unite-sources* *neocomplete-unite-source-neocomplete* neocomplete Nominates neocomplete completion candidates. The kind is "completion". This source is used in |(neocomplete_start_unite_complete)|. > imap (neocomplete_start_unite_complete) imap (neocomplete_start_unite_quick_match) < ============================================================================== EXTERNAL SOURCES *neocomplete-external-sources* neosnippet source: https://github.com/Shougo/neosnippet.vim include, file/include sources: https://github.com/Shougo/neoinclude.vim UltiSnips source: https://github.com/SirVer/ultisnips vimshell source: https://github.com/Shougo/vimshell.vim look source: https://github.com/ujihisa/neco-look ghc source: https://github.com/eagletmt/neco-ghc calc source: https://github.com/hrsh7th/vim-neco-calc ============================================================================== FAQ *neocomplete-faq* Q: My customization for neocomplete is invalid.

A: You must install "vim-ruby" from github to indent in neocomplete first. https://github.com/vim-ruby/vim-ruby neocomplete pops up a completion window automatically, but if the popup window is already visible, Vim cannot indent text. So you must choose "close popup window manually by or mappings" or "close popup window by user mappings". Q: mapping conflicts with |SuperTab| or |endwise| plugins.

But this function slows your Vim initialization. > call neocomplete#initialize() < Q: neocomplete conflicts when multibyte input in GVim. A: Because Vim multibyte IME integration is incomplete. You should use "fcitx" instead of "ibus". If you set |g:neocomplete#lock_iminsert| is non-zero, it may be fixed. Q: Freeze for a while and close opened folding when I begin to insert. https://github.com/Shougo/neocomplcache.vim/issues/368 A: I think you use 'foldmethod' is "expr" or "syntax". It is too heavy to use neocomplete (or other auto completion.) You should change 'foldmethod' option or install FastFold plugin. https://github.com/Konfekt/FastFold Note: In current version, neocomplete does not restore 'foldmethod'. Because it is too heavy. Q: I want to use Pydiction with neocomplete. A: You should set |g:neocomplete#sources#dictionary#dictionaries|. neocomplete can load Pydiction dictionary file. Q: Why does neocomplcache use if_lua besides if_python? Many people may not be able to use it because they do not have the root privilege to recompile vim. A: Because of the following reasons. 1. Python interface is not available on every Vim environment. For example, Android, iOS, non configured Vim, or etc. 2. Incompatibility between Python2 and Python3. I must rewrite for it. 3. Loading Python interface is slow (10~20ms), but loading Lua interface is absolutely fast (270ns). 4. Python2 and Python3 are not loaded at the same time on Unix environment. 5. Python itself is too large. 6. Python interface is slower than Lua interface (almost twice.) 7. Lua interface is stable (no crashes on latest Vim.) 8. Using C module (like vimproc, YouCompleteMe) is hard to compile on Windows environment. 9. Using both Python and C, like YouCompleteMe, is too unstable. Your Vim may crashes or causes mysterious errors. 10. To build if_lua is easy. 11. I think if_lua is the second level language in Vim (The first is Vim script.) Q: I want to disable preview window. A: > set completeopt-=preview < Q: I want to use "vim-lua-ftplugin". https://github.com/xolox/vim-lua-ftplugin A: Please set |g:neocomplete#sources#omni#input_patterns| as below.

Q: neocomplete will change external completeopt value (longest.) https://github.com/Shougo/neocomplcache.vim/issues/453 A: It is feature. Because "longest" completeopt conflicts with auto completion. To use "longest" option, you must disable auto completion. "longest" is good feature. But it is for manual completion only. Q: autoclose conflicts with neocomplete. https://github.com/Shougo/neocomplcache.vim/issues/350 A: It is autoclose mappings problem. I cannot fix it. You should use auto-pairs plugin instead of it. https://github.com/jiangmiao/auto-pairs Q: I want to complete by Erlang omnifunc. https://github.com/vim-erlang/vim-erlang-omnicomplete A: > if !exists('g:neocomplete#force_omni_input_patterns') let g:neocomplete#force_omni_input_patterns = {} endif let g:neocomplete#force_omni_input_patterns.erlang = \ '\<[[:digit:][:alnum:]_-]\+:[[:digit:][:alnum:]_-]*' Q: I want to look selected function's arguments in neocomplete.

You must use |neocomplete#start_manual_complete()| instead of . Q: My mapping never works. A: https://github.com/Shougo/neocomplete.vim/issues/334 Note: It is fixed in Vim 7.4.653. Q: When I press enter, Vim inserts new line instead of selected item. A: It is Vim's default behavior (feature.) If you want to select the item, you should map . > inoremap pumvisible()? "\" : "\" Q: After updating Vim, some completion plugins automatically select the last candidate in the popup menu. A: Vim 7.4.775 introduced "noselect" and "noinsert" options for 'completeopt'. It is likely that those completion plugins use keymappings such as to display the popup menu. However, there is no need to do this after 7.4.775 since neocomplete.vim handles that part. If that's the case, you will need to contact the author of the plugin and have it not send those key strokes if "noselect" or "noinsert" option is present in 'completeopt'. ============================================================================== vim:tw=78:ts=8:ft=help:norl:noet:fen:noet:
