==============================================================================
INTRODUCTION                                                *acp-introduction*

With this plugin, your vim comes to automatically opens popup menu for
completions when you enter characters or move the cursor in Insert mode. It
won't prevent you continuing entering characters.


==============================================================================
INSTALLATION                                                *acp-installation*

Put all files into your runtime directory. If you have the zip file, extract
it to your runtime directory.

You should place the files as follows:
>
        <your runtime directory>/plugin/acp.vim
        <your runtime directory>/doc/acp.txt
        ...
<
If you disgust to jumble up this plugin and other plugins in your runtime
directory, put the files into new directory and just add the directory path to
'runtimepath'. It's easy to uninstall the plugin.

And then update your help tags files to enable fuzzyfinder help. See
|add-local-help| for details.


==============================================================================
USAGE                                                              *acp-usage*

Once this plugin is installed, auto-popup is enabled at startup by default.

Which completion method is used depends on the text before the cursor. The
default behavior is as follows:

        kind      filetype    text before the cursor ~
        Keyword   *           two keyword characters
        Filename  *           a filename character + a path separator 
                              + 0 or more filename character
        Omni      ruby        ".", "::" or non-word character + ":"
                              (|+ruby| required.)
        Omni      python      "." (|+python| required.)
        Omni      xml         "<", "</" or ("<" + non-">" characters + " ")
        Omni      html/xhtml  "<", "</" or ("<" + non-">" characters + " ")
        Omni      css         (":", ";", "{", "^", "@", or "!")
                              + 0 or 1 space

Also, you can make user-defined completion and snipMate's trigger completion
(|acp-snipMate|) auto-popup if the options are set.

These behavior are customizable.

                                                                *acp-snipMate*
snipMate's Trigger Completion ~

snipMate's trigger completion enables you to complete a snippet trigger
provided by snipMate plugin
(http://www.vim.org/scripts/script.php?script_id=2540) and expand it.


To enable auto-popup for this completion, add following function to
plugin/snipMate.vim:
>
  fun! GetSnipsInCurrentScope()
    let snips = {}
    for scope in [bufnr('%')] + split(&ft, '\.') + ['_']
      call extend(snips, get(s:snippets, scope, {}), 'keep')
      call extend(snips, get(s:multi_snips, scope, {}), 'keep')
    endfor
    return snips
  endf
<
And set |g:acp_behaviorSnipmateLength| option to 1.

There is the restriction on this auto-popup, that the word before cursor must
consist only of uppercase characters.

                                                               *acp-perl-omni*
Perl Omni-Completion ~

AutoComplPop supports perl-completion.vim
(http://www.vim.org/scripts/script.php?script_id=2852).

To enable auto-popup for this completion, set |g:acp_behaviorPerlOmniLength|
option to 0 or more.


==============================================================================
COMMANDS                                                        *acp-commands*

                                                                  *:AcpEnable*
:AcpEnable
        enables auto-popup.

                                                                 *:AcpDisable*
:AcpDisable
        disables auto-popup.

                                                                    *:AcpLock*
:AcpLock
        suspends auto-popup temporarily.

        For the purpose of avoiding interruption to another script, it is
        recommended to insert this command and |:AcpUnlock| than |:AcpDisable|
        and |:AcpEnable| .

                                                                  *:AcpUnlock*
:AcpUnlock
        resumes auto-popup suspended by |:AcpLock| .

  let g:acp_mappingDriven = 0
<
        If non-zero, auto-popup is triggered by key mappings instead of
        |CursorMovedI| event. This is useful to avoid auto-popup by moving
        cursor in Insert mode.

  let g:acp_behaviorUserDefinedFunction = ''
<
        |g:acp_behavior-completefunc| for user-defined completion. If empty,
        this completion will be never attempted.

                                           *g:acp_behaviorUserDefinedMeets*  >
  let g:acp_behaviorUserDefinedMeets = ''
<
        |g:acp_behavior-meets| for user-defined completion. If empty, this
        completion will be never attempted.

                                             *g:acp_behaviorSnipmateLength*  >

  let g:acp_behaviorKeywordLength = 2
<
        Length of keyword characters before the cursor, which are needed to
        attempt keyword completion. If negative value, this completion will be
        never attempted.

                                             *g:acp_behaviorKeywordIgnores*  >
  let g:acp_behaviorKeywordIgnores = []
<
        List of string. If a word before the cursor matches to the front part
        of one of them, keyword completion won't be attempted.

        E.g., when there are too many keywords beginning with "get" for the
        completion and auto-popup by entering "g", "ge", or "get" causes
        response degradation, set ["get"] to this option and avoid it.

  let g:acp_behaviorPythonOmniLength = 0
<
        Length of keyword characters before the cursor, which are needed to
        attempt python omni-completion. If negative value, this completion

        This option is for advanced users. This setting overrides other
        behavior options. This is a |Dictionary|. Each key corresponds to a
        filetype. '*' is default. Each value is a list. These are attempted in
        sequence until completion item is found. Each element is a
        |Dictionary| which has following items:

        "command":                                    *g:acp_behavior-command*
          Command to be fed to open popup menu for completions.

        "completefunc":                          *g:acp_behavior-completefunc*
          'completefunc' will be set to this user-provided function during the
          completion. Only makes sense when "command" is "<C-x><C-u>".

        "meets":                                        *g:acp_behavior-meets*
          Name of the function which dicides whether or not to attempt this
          completion. It will be attempted if this function returns non-zero.
          This function takes a text before the cursor.

        "onPopupClose":                          *g:acp_behavior-onPopupClose*
          Name of the function which is called when popup menu for this
          completion is closed. Following completions will be suppressed if
          this function returns zero.

        "repeat":                                      *g:acp_behavior-repeat*
          If non-zero, the last completion is automatically repeated.

CHANGELOG                                                      *acp-changelog*

2.14.1
  - Changed the way of auto-popup for avoiding an issue about filename
    completion.
  - Fixed a bug that popup menu was opened twice when auto-popup was done.

2.14
  - Added the support for perl-completion.vim.

2.13
  - Changed to sort snipMate's triggers.
  - Fixed a bug that a wasted character was inserted after snipMate's trigger
    completion.

2.12.1
  - Changed to avoid a strange behavior with Microsoft IME.

2.12
  - Added g:acp_behaviorKeywordIgnores option.
  - Added g:acp_behaviorUserDefinedMeets option and removed
    g:acp_behaviorUserDefinedPattern.
  - Changed to do auto-popup only when a buffer is modified.
  - Changed the structure of g:acp_behavior option.
  - Changed to reflect a change of behavior options (named g:acp_behavior*)
    any time it is done.
  - Fixed a bug that completions after omni completions or snipMate's trigger
    completion were never attempted when no candidate for the former
    completions was found.

2.11.1
  - Fixed a bug that a snipMate's trigger could not be expanded when it was
    completed.

2.11
  - Implemented experimental feature which is snipMate's trigger completion.

2.10
  - Improved the response by changing not to attempt any completion when
    keyword characters are entered after a word which has been found that it
    has no completion candidate at the last attempt of completions.
  - Improved the response by changing to close popup menu when <BS> was
    pressed and the text before the cursor would not match with the pattern of
    current behavior.

2.9
  - Changed default behavior to support XML omni completion.
  - Changed default value of g:acp_behaviorKeywordCommand option.
    The option with "\<C-p>" cause a problem which inserts a match without
    <CR> when 'dictionary' has been set and keyword completion is done.
  - Changed to show error message when incompatible with a installed vim.

2.8.1
  - Fixed a bug which inserted a selected match to the next line when
    auto-wrapping (enabled with 'formatoptions') was performed.

2.8
  - Added g:acp_behaviorUserDefinedFunction option and
    g:acp_behaviorUserDefinedPattern option for users who want to make custom
    completion auto-popup.
  - Fixed a bug that setting 'spell' on a new buffer made typing go crazy.

2.7
  - Changed naming conventions for filenames, functions, commands, and options 
    and thus renamed them.
  - Added g:acp_behaviorKeywordCommand option. If you prefer the previous
    behavior for keyword completion, set this option "\<C-n>".
  - Changed default value of g:acp_ignorecaseOption option.

  The following were done by Ingo Karkat:

  - ENH: Added support for setting a user-provided 'completefunc' during the
    completion, configurable via g:acp_behavior. 
  - BUG: When the configured completion is <C-p> or <C-x><C-p>, the command to
    restore the original text (in on_popup_post()) must be reverted, too. 
  - BUG: When using a custom completion function (<C-x><C-u>) that also uses
    an s:...() function name, the s:GetSidPrefix() function dynamically
    determines the wrong SID. Now calling s:DetermineSidPrefix() once during
    sourcing and caching the value in s:SID. 
  - BUG: Should not use custom defined <C-X><C-...> completion mappings. Now
    consistently using unmapped completion commands everywhere. (Beforehand,
    s:PopupFeeder.feed() used mappings via feedkeys(..., 'm'), but
    s:PopupFeeder.on_popup_post() did not due to its invocation via
    :map-expr.) 

2.6:
  - Improved the behavior of omni completion for HTML/XHTML.

2.5:
  - Added some options to customize behavior easily:
      g:AutoComplPop_BehaviorKeywordLength
      g:AutoComplPop_BehaviorFileLength
      g:AutoComplPop_BehaviorRubyOmniMethodLength
      g:AutoComplPop_BehaviorRubyOmniSymbolLength

  - Changed to set 'lazyredraw' while a popup menu is visible to avoid
    flickering.
  - Changed a behavior for CSS.

  - Added a behavior for CSS to support omni completion.

2.2:

    map/unmap "i" and "R".

2.1:
  - Fixed the problem caused by "." command in Normal mode.
  - Changed to map "i" and "R" to feed completion command after starting
    Insert mode.
  - Avoided the problem caused by Windows IME.

2.0:
  - Changed to use CursorMovedI event to feed a completion command instead of
    key mapping. Now the auto-popup is triggered by moving the cursor.
  - Changed to feed completion command after starting Insert mode.
  - Removed g:AutoComplPop_MapList option.

1.7:
  - Added behaviors for HTML/XHTML. Now supports the omni completion for

  - Added g:AutoComplPop_Behavior option.
  - Added g:AutoComplPop_CompleteoptPreview option.
  - Removed g:AutoComplPop_MinLength option.
  - Removed g:AutoComplPop_MaxLength option.
  - Removed g:AutoComplPop_PopupCmd option.

1.2:
  - Fixed bugs related to 'completeopt'.
