==============================================================================
INTRODUCTION					*deoplete-introduction*

*deoplete* is the abbreviation of "dark powered neo-completion".  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 |if_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| or |:NeoBundleRemotePlugins| (for using
   NeoBundle) and restart Neovim.
3. Execute the |:DeopleteEnable| command 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|.

==============================================================================
INTERFACE					*deoplete-interface*

------------------------------------------------------------------------------
COMMANDS 					*deoplete-commands*

:DeopleteEnable				*:DeopleteEnable*
		Validate deoplete and initialize it.

------------------------------------------------------------------------------
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_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_completion_start_length*
g:deoplete#auto_completion_start_length
		This variable controls the number of the input completion
		at the time of key input automatically.

		Default value: 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.

				*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#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 =

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: {}

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

		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.

==============================================================================
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.

				*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
		|g:deoplete#auto_completion_start_length| 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: 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-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

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.

Q: I want to use C/C++ omni completion with deoplete.

A: You can use |clang_complete| or |vim-marching|.

https://github.com/Rip-Rip/clang_complete
https://github.com/osyo-manga/vim-marching

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.  You
should use faster machine for deoplete.

Q: I want to complete AAA using deoplete.

A: You can create the source for it.  Why don't create the source if you need?

Q: I want to use jedi-vim omni completion with deoplete.

A: You should install deoplete-jedi instead of jedi-vim. >
https://github.com/zchee/deoplete-jedi

Q: When I press enter, neovim close the popup instead of inserting new line.

A: It is Vim/neovim's default behavior (feature.)  If you want to insert the
new line, you should map <CR>. >

	inoremap <silent> <CR> <C-r>=<SID>my_cr_function()<CR>
	function! s:my_cr_function() abort
	  return deoplete#mappings#close_popup() . "\<CR>"
	endfunction

Q: I want to use "vim-lua-ftplugin".
https://github.com/xolox/vim-lua-ftplugin

A: Please set the config as below.
>
	let g:lua_check_syntax = 0
	let g:lua_complete_omni = 1
	let g:lua_complete_dynamic = 0
	let g:lua_define_completion_mappings = 0

	let g:deoplete#omni#functions.lua = 'xolox#lua#omnifunc'
	"let g:deoplete#omni#functions.lua = 'xolox#lua#completefunc'
<
Q: I want to disable buffer source.

A: You can use |g:deoplete#ignore_sources|. >

	let g:deoplete#ignore_sources = {}
	let g:deoplete#ignore_sources._ = ['buffer']

Q: I want to complete go candidates.

A: You should install deoplete-go source.
https://github.com/zchee/deoplete-go

Q: I want to complete the candidates from other files.
https://github.com/Shougo/deoplete.nvim/issues/133

A: You must install context_filetype plugin.
https://github.com/Shougo/context_filetype.vim
And you must set |g:context_filetype#same_filetypes| variable.
