How to disable AutoComplPop completions in comments?

问题

I've recently started using AutoComplPop, but I find the popup annoying when I'm writing comments (as I usually don't need autocomplition when writing a comment).

Is there a configuration option or a quick hack that can effectively disable AutoComplPop when the insertion point is in a comment?

回答1:

To answer the question of performance when checking the syntax on every cursor move, I had to implement this myself, and made this into the OnSyntaxChange plugin.

With this plugin, setting this up can be done in just three lines (e.g. in .vimrc):

call OnSyntaxChange#Install('Comment', '^Comment$', 0, 'i')
autocmd User SyntaxCommentEnterI silent! AcpLock
autocmd User SyntaxCommentLeaveI silent! AcpUnlock

For me, the performance impact is noticeable (depending on the filetype and syntax), but tolerable. Try for yourself!

You need to check via a hook into CursorMovedI that you're currently in a comment, and can then use AutoComplPop's :AcpLock to disable it temporarily. (And undo with :AcpUnlock once you move out of comments.)

Detecting comments for various filetypes is best done by querying the syntax highlighting; this way, you benefit from the syntax definitions of existing filetypes.

Here's a snippet for this:

function! IsOnSyntaxItem( syntaxItemPattern )
    " Taking the example of comments:
    " Other syntax groups (e.g. Todo) may be embedded in comments. We must thus
    " check whole stack of syntax items at the cursor position for comments.
    " Comments are detected via the translated, effective syntax name. (E.g. in
    " Vimscript, 'vimLineComment' is linked to 'Comment'.)
    for l:id in synstack(line('.'), col('.'))
        let l:actualSyntaxItemName = synIDattr(l:id, 'name')
        let l:effectiveSyntaxItemName = synIDattr(synIDtrans(l:id), 'name')
        if l:actualSyntaxItemName =~# a:syntaxItemPattern || l:effectiveSyntaxItemName =~# a:syntaxItemPattern
            return 1
        endif
    endfor
    return 0
endfunction

With this, you should be able to stitch together a solution.
