It provides asynchronous keyword completion system in the current buffer. Note: deoplete may consume more memory than other plugins do. Improvements in deoplete in comparison to |neocomplete|: 1. Real asynchronous completion behavior like |YouCompleteMe| by default. 2. Uses Python3 to implement sources. 3. Removes legacy interface. 4. Requires |+python3|. ============================================================================== INSTALL *deoplete-install* Note: deoplete requires Neovim(latest is recommended) with Python3 enabled. 1. Extract the files and put them in your Neovim directory (usually `$XDG_CONFIG_HOME/nvim/`). 2. Execute the |:UpdateRemotePlugins| and restart Neovim. 3. Call |deoplete#enable()| or set "let g:deoplete#enable_at_startup = 1" in your `init.vim` If ":echo has('python3')" returns `1`, then you're done; otherwise, see below. You can enable Python3 interface with pip: > sudo pip3 install neovim If you want to read for Neovim-python/python3 interface install documentation, you should read |nvim-python| and the Wiki. https://github.com/zchee/deoplete-jedi/wiki/Setting-up-Python-for-Neovim You can check the Python3 installation by nvim-python-doctor. https://github.com/tweekmonster/nvim-python-doctor ============================================================================== INTERFACE *deoplete-interface* ------------------------------------------------------------------------------ VARIABLES *deoplete-variables* *g:deoplete#enable_at_startup* g:deoplete#enable_at_startup Deoplete gets started automatically when Neovim starts if this value is 1. With the default value 0, you cannot use deoplete unless you start it manually. *g:deoplete#enable_ignore_case* g:deoplete#enable_ignore_case When deoplete looks for candidate completion, this variable controls whether deoplete ignores the upper- and lowercase. If it is 1, deoplete ignores case. Default value: same with your 'ignorecase' value *g:deoplete#enable_smart_case* g:deoplete#enable_smart_case When a capital letter is included in input, deoplete does not ignore the upper- and lowercase. Default value: same with your 'smartcase' value *g:deoplete#enable_camel_case* g:deoplete#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 |deoplete-filter-matcher_fuzzy| or |deoplete-filter-matcher_full_fuzzy|. Default value: 0 *g:deoplete#enable_refresh_always* g:deoplete#enable_refresh_always Deoplete refreshes the candidates automatically if this value is 1. Note: It increases the screen flicker. Default value: 0 *g:deoplete#auto_complete_start_length* g:deoplete#auto_complete_start_length This variable controls the number of the input completion at the time of key input automatically. Note: It is the deprecated option. You should change |deoplete-source-attribute-min_pattern_length|. Default: 2 *g:deoplete#disable_auto_complete* g:deoplete#disable_auto_complete It controls whether you invalidate automatic completion. If it is 1, automatic completion becomes invalid, but can use the manual completion by |deoplete#mappings#manual_complete()|. Default value: 0 *b:deoplete_disable_auto_complete* b:deoplete_disable_auto_complete Buffer local variable of |g:deoplete#disable_auto_complete|. *g:deoplete#enable_debug* g:deoplete#enable_debug It enables deoplete debug mode. The debug print feature is enabled. *g:deoplete#enable_profile* g:deoplete#enable_profile It enables deoplete profile mode. If it is 1, deoplete will print the time information to |deoplete#enable_logging()| logfile. Must be set in init.vim before to start the Neovim. Does not support command line. Default value: 0 *g:deoplete#delimiters* g:deoplete#delimiters Delimiters list. Default value: ['/', '.', '::', ':', '#'] *g:deoplete#max_list* g:deoplete#max_list If the list of candidates exceeds the limit, not all candidates will show up. Default value: 100 *g:deoplete#max_abbr_width* g:deoplete#max_abbr_width If the candidate abbr length exceeds the length it will be cut down. If it is less than equal 0, this feature will be disabled. Default value: 80 *g:deoplete#max_menu_width* g:deoplete#max_menu_width If the candidate menu length exceeds the length it will be cut down. If it is less than equal 0, this feature will be disabled. Default value: 40 *g:deoplete#auto_complete_delay* g:deoplete#auto_complete_delay It is the auto completion delay time after your input. The unit is ms. Default value: 0 *g:deoplete#keyword_patterns* g:deoplete#keyword_patterns This dictionary records keyword patterns to buffer completion. This is appointed in regular expression string or list every file type. Note: It is Python3 regexp. But "\k" is converted to 'iskeyword' pattern. > let g:deoplete#keyword_patterns = {} let g:deoplete#keyword_patterns.tex = '\\?[a-zA-Z_]\w*' < Default value: in g:deoplete#_keyword_patterns *b:deoplete_keyword_patterns* b:deoplete_keyword_patterns Buffer local variable of |g:deoplete#keyword_patterns|. *g:deoplete#omni_patterns* g:deoplete#omni_patterns This dictionary records keyword patterns to Omni completion. This is appointed in regular expression string or list every file type. If this pattern is not defined or empty pattern, deoplete does not call 'omnifunc'. Note: If it is a set, deoplete will call 'omnifunc' directly. So almost deoplete features are disabled. Note: It is Vim regexp. > let g:deoplete#omni_patterns = {} let g:deoplete#omni_patterns.java = '[^. *\t]\.\w*' let g:deoplete#omni_patterns.php = \ '\h\w*\|[^. \t]->\%(\h\w*\)\?\|\h\w*::\%(\h\w*\)\?' < Default value: in g:deoplete#_omni_patterns *b:deoplete_omni_patterns* b:deoplete_omni_patterns Buffer local variable of |g:deoplete#omni_patterns|. *g:deoplete#sources* g:deoplete#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 load some sources in C++ filetype. If the value is [], it will load all sources. Default value: {} > " Examples: let g:deoplete#sources = {} let g:deoplete#sources._ = ['buffer'] let g:deoplete#sources.cpp = ['buffer', 'tag'] < *b:deoplete_sources* b:deoplete_sources Buffer local variable of |g:deoplete#sources|. It must be the source names list. > " Examples: " In cmdwin, only use buffer source. autocmd CmdwinEnter * let b:deoplete_sources = ['buffer'] < *g:deoplete#ignore_sources* g:deoplete#ignore_sources It is a dictionary to decide ignore source names. Default value: {} *b:deoplete_ignore_sources* b:deoplete_ignore_sources Buffer local variable of |g:deoplete#ignore_sources|. It must be the source names list. *g:deoplete#member#prefix_patterns* g:deoplete#member#prefix_patterns This dictionary records prefix patterns to member completion. This is appointed in regular expression string or list every file type. If this pattern is not defined or empty pattern, deoplete does not complete member candidates. Note: It is Python3 regexp. Default value: in g:deoplete#member#_prefix_patterns *b:deoplete_member_prefix_patterns* b:deoplete_member_prefix_patterns Buffer local variable of |g:deoplete#member#prefix_patterns|. *g:deoplete#omni#input_patterns* g:deoplete#omni#input_patterns This dictionary records keyword patterns to Omni completion. This is appointed in regular expression string or list every file type. If this pattern is not defined or empty pattern, deoplete does not call 'omnifunc'. Note: Some omnifuncs which moves the cursor is not worked. For example, htmlcomplete, vim-go, etc... Note: It is Python3 regexp. > let g:deoplete#omni#input_patterns = {} let g:deoplete#omni#input_patterns.ruby = \ ['[^. *\t]\.\w*', '[a-zA-Z_]\w*::'] let g:deoplete#omni#input_patterns.java = '[^. *\t]\.\w*' < Default value: in g:deoplete#omni#_input_patterns *b:deoplete_omni_input_patterns* b:deoplete_omni_input_patterns Buffer local variable of |g:deoplete#omni#input_patterns|. *g:deoplete#omni#functions* g:deoplete#omni#functions This dictionary records the functions to Omni completion. This is the omnifunc name list every file type. If this pattern is not defined or empty pattern, deoplete use 'omnifunc'. Note: It supports context filetype feature instead of 'omnifunc'. You can call the omnifunc in the embedded language. *b:deoplete_omni_functions* b:deoplete_omni_functions Buffer local variable of |g:deoplete#omni#functions|. *g:deoplete#file#enable_buffer_path* g:deoplete#file#enable_buffer_path If it is 1, file source complete the files from the buffer path instead of the current directory. Default value: 0 *b:deoplete_file_enable_buffer_path* b:deoplete_file_enable_buffer_path Buffer local variable of |g:deoplete#file#enable_buffer_path|. *g:deoplete#tag#cache_limit_size* g:deoplete#tag#cache_limit_size It sets file size to make a cache of a file in tag source. If a tag file is bigger than this size, deoplete does not make the tag file cache. Default value: 500000 ------------------------------------------------------------------------------ FUNCTIONS *deoplete-functions* *deoplete#initialize()* deoplete#initialize() Initialize deoplete and sources. Note: You should call it in |VimEnter| autocmd. User customization for deoplete must be set before initialization of deoplete. *deoplete#enable()* deoplete#enable() Enable deoplete auto completion. Note: It changes the global state. *deoplete#disable()* deoplete#disable() Disable deoplete auto completion. Note: It changes the global state. *deoplete#toggle()* deoplete#toggle() Toggle deoplete auto completion. Note: It changes the global state. *deoplete#custom#set()* deoplete#custom#set({source-name}, {option-name}, {value}) 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. Note: You must call it before using deoplete. > " Examples: " Use head matcher instead of fuzzy matcher call deoplete#custom#set('_', 'matchers', ['matcher_head']) " Use auto delimiter feature call deoplete#custom#set('_', 'converters', \ ['converter_auto_delimiter', 'remove_overlap']) call deoplete#custom#set('buffer', 'min_pattern_length', 9999) " Change the source rank call deoplete#custom#set('buffer', 'rank', 9999) " Enable buffer source in C/C++ files only. call deoplete#custom#set('buffer', 'filetypes', ['c', 'cpp']) " Disable the candidates in Comment/String syntaxes. call deoplete#custom#set('_', \ 'disabled_syntaxes', ['Comment', 'String']) " Change the truncate width. call deoplete#custom#set('javacomplete2', \ 'max_abbr_width', 20) call deoplete#custom#set('javacomplete2', \ 'max_menu_width', 80) " Disable the truncate feature. call deoplete#custom#set('javacomplete2', \ 'max_abbr_width', 0) call deoplete#custom#set('javacomplete2', \ 'max_menu_width', 0) " Change the source mark. call deoplete#custom#set('buffer', 'mark', '*') < *deoplete#enable_logging()* deoplete#enable_logging({level}, {logfile}) Enable logging for debugging purposes. Set {level} to "DEBUG", "INFO", "WARNING", "ERROR", or "CRITICAL". {logfile} is the file where log messages are written. Messages are appended to this file. Each log session will start with "--- Deoplete Log Start ---". ------------------------------------------------------------------------------ KEY MAPPINGS *deoplete-key-mappings* *deoplete#mappings#manual_complete()* deoplete#mappings#manual_complete([{sources}]) Use this function with |:inoremap| (|:map-expression|). It calls the completion of deoplete. You can use it with custom completion setups. You can provide a list of {sources}: It can be the name of a source or a list of sources name. Note: It blocks your neovim. If you want to trigger deoplete manually, see also |g:deoplete#disable_auto_complete|, which should be 1 then typically. > inoremap \ pumvisible() ?

"\" endfunction < ============================================================================== SOURCES *deoplete-sources* buffer *deoplete-source-buffer* It collects keywords from current buffer and the buffers which have same 'filetype'. Note: It takes time to get the candidates in the first time if you want to edit the large files(like Vim 22000 lines eval.c). member *deoplete-source-member* It collects members from current buffer. tag *deoplete-source-tag* It collects keywords from |ctags| files. Note: It only supports UTF-8 encoding tag file. file *deoplete-source-file* This source collects keywords from local files. omni *deoplete-source-omni* This source collects keywords from 'omnifunc'. Note: It is not asynchronous. dictionary *deoplete-source-dictionary* This source collects keywords from 'dictionary'. ============================================================================== FILTERS *deoplete-filters* *deoplete-filter-matcher_default* Default matchers: ['matcher_length', 'matcher_fuzzy'] You can change it by |deoplete#custom#set()|. *deoplete-filter-sorter_default* Default sorters: ['sorter_rank']. You can change it by |deoplete#custom#set()|. *deoplete-filter-converter_default* Default converters: ['converter_remove_overlap', 'converter_truncate_abbr', 'converter_truncate_menu']. You can change it by |deoplete#custom#set()|. *deoplete-filter-matcher_head* matcher_head Head matching matcher. *deoplete-filter-matcher_fuzzy* matcher_fuzzy Fuzzy matching matcher. *deoplete-filter-matcher_full_fuzzy* matcher_full_fuzzy Full fuzzy matching matcher. It accepts partial fuzzy matches like YouCompleteMe. *deoplete-filter-matcher_length* matcher_length Length matching matcher. It removes shorter candidates than user input. *deoplete-filter-sorter_rank* sorter_rank Matched rank order sorter. The higher the head matched word or already selected. *deoplete-filter-sorter_word* sorter_word Word order sorter. *deoplete-filter-converter_remove_overlap* converter_remove_overlap It removes overlapped text in a candidate's word. *deoplete-filter-converter_auto_delimiter* converter_auto_delimiter It adds delimiter characters in a candidate's word. *deoplete-filter-converter_auto_paren* converter_auto_paren It adds parenthes character in a candidate's word. It is useful if you use |neopairs| or |neosnippet| plugins. *deoplete-filter-converter_remove_paren* converter_remove_paren It removes parenthes character in a candidate's word. *deoplete-filter-converter_truncate_abbr* converter_truncate_abbr It truncates a candidate's abbr by the current window width. *deoplete-filter-converter_truncate_menu* converter_truncate_menu It truncates a candidate's menu by the current window width. ============================================================================== CREATE SOURCE *deoplete-create-source* To create source, you should read default sources implementation in rplugin/python3/deoplete/sources/*.py. The files in rplugin/python3/deoplete/sources/*.py are automatically loaded and deoplete creates new Source class object. Source class must extend Base class in ".base". Note: The sources must be created by Python3 language. Note: If you call Vim functions in your source, it is not asynchronous. ------------------------------------------------------------------------------ SOURCE ATTRIBUTES *deoplete-source-attributes* *deoplete-source-attribute-__init__* __init__ (Function) Source constructor. It will be called in initializing. It must call Base constructor. This function takes {self} and {vim} as its parameters. *deoplete-source-attribute-name* name (String) (Required) The name of a source. Note: It must be same of the source filaname. *deoplete-source-attribute-filetypes* filetypes (List) (Optional) Available filetype list. If you omit it, this source available in all filetypes. *deoplete-source-attribute-rank* rank (Number) (Optional) Source priority. Higher values imply higher priority. If you omit it, it is set 100. Note: It is high priority than match position. *deoplete-source-attribute-min_pattern_length* min_pattern_length (Number) (Optional) Required pattern length for completion. If you omit it, it is set "2" value. *deoplete-source-attribute-max_pattern_length* max_pattern_length (Number) (Optional) Ignored pattern length for completion. It is useful to edit BASE64 files. If you omit it, it is set "80" value. *deoplete-source-attribute-max_abbr_width* max_abbr_width (Number) (Optional) If the candidate abbr length exceeds the length it will be cut down. It it is less than or equal 0, it will be disabled. If you omit it, it is set |g:deoplete#max_abbr_width| value. *deoplete-source-attribute-max_menu_width* max_menu_width (Number) (Optional) If the candidate menu length exceeds the length it will be cut down. It it is less than or equal 0, it will be disabled. If you omit it, it is set |g:deoplete#max_menu_width| value. *deoplete-source-attribute-input_pattern* input_pattern (String) (Optional) If it is matched, deoplete ignores |deoplete-source-attribute-min_pattern_length|. It is useful for omni function sources. Note: If the source set the attribute, it must define |deoplete-source-attribute-get_complete_position| attribute. Note: It is Python3 regexp. If you omit it, this feature is ignored. *deoplete-source-attribute-is_bytepos* is_bytepos (Bool) (Optional) If it is True, |deoplete-source-attribute-get_complete_position| returns byteposition instead of character position. The default is False. It is useful for Vim script to create sources. Because Vim script string uses byte position. Python string uses character position. *deoplete-source-attribute-debug_enabled* debug_enabled (Bool) (Optional) If it is True, the debug log feature is enabled in the source. *deoplete-source-attribute-matchers* matchers (List) (Optional) Source default matchers list. If you omit it, |deoplete-filter-matcher_default| is used. *deoplete-source-attribute-sorters* sorters (List) (Optional) Source default sorters list. If you omit it, |deoplete-filter-sorter_default| is used. *deoplete-source-attribute-converters* converters (List) (Optional) Source default converters list. If you omit it, |deoplete-filter-converter_default| is used. *deoplete-source-attribute-disabled_syntaxes* disabled_syntaxes (List) (Optional) Source disabled syntaxes list. If you omit it, this feature is ignored. *deoplete-source-attribute-get_complete_position* get_complete_position (Function) (Optional) It is called to get complete position. It takes {self} and {context} as its parameter and returns complete position in current line. Here, {context} is the context information when the source is called(|deoplete-notation-{context}|). If you omit it, deoplete will use the position using |g:deoplete#keyword_patterns|. Note: |deoplete-source-attribute-is_bytepos| is True, it must return byte position. *deoplete-source-attribute-gather_candidates* gather_candidates (Function) (Required) It is called to gather candidates. It takes {self} and {context} as its parameter and returns a list of {candidate}. {candidate} must be String or Dictionary contains |deoplete-candidate-attributes|. Here, {context} is the context information when the source is called(|deoplete-notation-{context}|). Note: The source must not filter the candidates by user input. It is |deoplete-filters| work. If the source filter the candidates, user cannot filter the candidates by fuzzy match. *deoplete-source-attribute-on_post_filter* on_post_filter (Function) (Optional) It is called after the candidates are filtered. It takes {self} and {context} as its parameter and returns a list of {candidate}. *deoplete-source-attribute-on_event* on_event (Function) (Optional) It is called when |BufEnter|, |BufRead|, |BufNewFile|, |BufNew|, |BufWinEnter|, |BufWritePost|. It is useful to make cache. It takes {self} and {context} as its parameter. *deoplete-source-attribute-__* __{name} (Unknown) (Optional) Additional source information. Note: Recommend sources save variables instead of global variables. {context} *deoplete-notation-{context}* A dictionary to give context information. The followings are the primary information. input (String) The input string of current line. complete_position (Number) The complete position of current source. complete_str (String) The complete string of current source. filetype (String) Current 'filetype'. filetypes (List) It contains current 'filetype' and same filetypes and composite filetypes. ------------------------------------------------------------------------------ CANDIDATE ATTRIBUTES *deoplete-candidate-attributes* *deoplete-candidate-attribute-name* word (String) (Required) The completion word of a candidate. It is used for matching inputs. *deoplete-candidate-attribute-abbr* abbr (String) (Optional) The abbreviation of a candidate. It is displayed in popup window. *deoplete-candidate-attribute-kind* kind (String) (Optional) The kind of a candidate. It is displayed in popup window. *deoplete-candidate-attribute-menu* menu (String) (Optional) The menu information of a candidate. It is displayed in popup window. *deoplete-candidate-attribute-info* info (String) (Optional) The preview information of a candidate. If 'completeopt' contains "preview", it will be displayed in |preview-window|. *deoplete-candidate-attribute-dup* dup (Number) (Optional) If it is non zero, the item will be displayed in the popup menu when an item with the same word is already present. ============================================================================== CREATE FILTER *deoplete-create-filter* ============================================================================== EXTERNAL SOURCES *deoplete-external-sources* neco-vim: "vim" source for Vim script https://github.com/Shougo/neco-vim neosnippet: "neosnippet" source https://github.com/Shougo/neosnippet.vim neoinclude: "include" and "file/include" sources https://github.com/Shougo/neoinclude.vim neco-syntax: "syntax" source https://github.com/Shougo/neco-syntax vimshell: "vimshell" source for vimshell https://github.com/Shougo/vimshell.vim neco-ghc: "ghc" source for Haskell https://github.com/eagletmt/neco-ghc vim-racer: "racer" source for Rust https://github.com/racer-rust/vim-racer UltiSnips source: "ultisnips" source for UltiSnips https://github.com/SirVer/ultisnips clang-complete: "clang_complete" source for C/C++/Objective-C https://github.com/Rip-Rip/clang_complete deoplete-go: "go" source for Go https://github.com/zchee/deoplete-go elixir.nvim: "elixir" source for Elixir https://github.com/awetzel/elixir.nvim deoplete-jedi: "jedi" source for Python https://github.com/zchee/deoplete-jedi perlomni.vim: "perlomni" source for Perl https://github.com/c9s/perlomni.vim deoplete-typescript: "typescript" source for typescript https://github.com/mhartington/deoplete-typescript deoplete-clang: "clang" source for C/C++ https://github.com/zchee/deoplete-clang async-clj-omni: "async_clj" source for Clojure https://github.com/SevereOverfl0w/async-clj-omni deoplete-ternjs: "ternjs" source for JavaScript https://github.com/carlitux/deoplete-ternjs deoplete-swift: "swift" source for Swift https://github.com/landaire/deoplete-swift neovim-intellij-complete-deoplete: "intellij" source for Intellij IDE https://github.com/vhakulinen/neovim-intellij-complete-deoplete tmux-complete: "tmuxcomplete" source for tmux panes. https://github.com/wellle/tmux-complete.vim ============================================================================== EXTERNAL PLUGINS *deoplete-external-plugins* These are my recommended plugins for deoplete. context_filetype.vim: It adds the context filetype feature. https://github.com/Shougo/context_filetype.vim neopairs.vim: It inserts the parentheses pairs automatically. https://github.com/Shougo/neopairs.vim echodoc.vim: It prints the documentation you have completed. https://github.com/Shougo/echodoc.vim neoinclude.vim: You can completes the candidates from the included files and included path. https://github.com/Shougo/neoinclude.vim FastFold: Speed up the updating folds when you use auto completion plugins. https://github.com/Konfekt/FastFold ============================================================================== EXTERNAL OMNIFUNCS *deoplete-external-omnifuncs* These are my recommended omnifuncs for deoplete. vim-dutly: D language omnifunc https://github.com/idanarye/vim-dutyl phpcompleted-extended: PHP omnifunc https://github.com/m2mdas/phpcomplete-extended ============================================================================== FAQ *deoplete-faq* Q: deoplete does not work. A: 1. Please update neovim to latest version. 2. Please update neovim python3 module to latest version. > $ sudo pip3 install neovim --upgrade < 3. Please execute |:UpdateRemotePlugins| or |:NeoBundleRemotePlugins| (for using NeoBundle) command manually. 4. Please check if Python3 interface works. You can check it by ":echo has('python3')" command. https://github.com/neovim/neovim/wiki/Troubleshooting#python-support-isnt-working 5. Please enable debug mode from command line and upload the log file. > $ export NVIM_PYTHON_LOG_FILE=/tmp/log $ export NVIM_PYTHON_LOG_LEVEL=DEBUG $ neovim ... Use deoplete $ cat /tmp/log_{PID} Q: I want to get quiet messages in auto completion. A: You can disable the messages through the 'shortmess' option. > if has("patch-7.4.314") set shortmess+=c endif < Q: I want to look selected function's arguments in deoplete. But I don't like preview window feature. A: You can do it by |echodoc|. http://github.com/Shougo/echodoc.vim Q: I want to use auto select feature like |neocomplete|. A: You can use it by the 'completeopt' option. > set completeopt+=noinsert Q: I want to lock auto completion. A: Please use |b:deoplete_disable_auto_complete|. Q: Ruby omni completion does not work in neovim. A: It is feature. Because, the default Ruby omni completion(RubyOmniComplete) uses if_ruby feature. But neovim does not support it. You should use vim-monster plugin for ruby completion. https://github.com/osyo-manga/vim-monster Q: I want to use C/C++ omni completion with deoplete. A: You can use |clang_complete| or |deoplete-clang|. https://github.com/Rip-Rip/clang_complete https://github.com/zchee/deoplete-clang For clang_complete configuration is below. > let g:clang_complete_auto = 0 let g:clang_auto_select = 0 let g:clang_omnicppcomplete_compliance = 0 let g:clang_make_default_keymappings = 0 "let g:clang_use_library = 1 Current clang_complete supports the original deoplete source. It is better than using omni source. Q: I want to use head matcher instead of fuzzy matcher. A: > " Use head matcher instead of fuzzy matcher call deoplete#custom#set('_', 'matchers', ['matcher_head']) Q: Is deoplete faster than neocomplete? A: No. Deoplete is asynchronous completion plugin. But it does not mean that it is faster than neocomplete. It can skip the completion if you input the characters too fast. I think it is great than the speed.
