INTRODUCTION *ack*
|
||
|
|
|
||
|
|
This plugin is a front for the Perl module App::Ack. Ack can be used as a
|
||
|
|
replacement for grep. This plugin will allow you to run ack from vim, and
|
||
|
|
shows the results in a split window.
|
||
|
|
|
||
|
|
:Ack[!] [options] {pattern} [{directory}] *:Ack*
|
||
|
|
|
||
|
|
Search recursively in {directory} (which defaults to the current
|
||
|
|
directory) for the {pattern}. Behaves just like the |:grep| command, but
|
||
|
|
will open the |Quickfix| window for you. If [!] is not given the first
|
||
|
|
occurrence is jumped to.
|
||
|
|
|
||
|
|
:AckAdd [options] {pattern} [{directory}] *:AckAdd*
|
||
|
|
|
||
|
|
Just like |:Ack|, but instead of making a new list, the matches are
|
||
|
|
appended to the current |quickfix| list.
|
||
|
|
|
||
|
|
:AckFromSearch [{directory}] *:AckFromSearch*
|
||
|
|
|
||
|
|
Just like |:Ack| but the pattern is from previous search.
|
||
|
|
|
||
|
|
:LAck [options] {pattern} [{directory}] *:LAck*
|
||
|
|
|
||
|
|
Just like |:Ack| but instead of the |quickfix| list, matches are placed in
|
||
|
|
the current |location-list|.
|
||
|
|
|
||
|
|
:LAckAdd [options] {pattern} [{directory}] *:LAckAdd*
|
||
|
|
|
||
|
|
Just like |:AckAdd| but instead of the |quickfix| list, matches are added
|
||
|
|
to the current |location-list|
|
||
|
|
|
||
|
|
:AckFile [options] {pattern} [{directory}] *:AckFile*
|
||
|
|
|
||
|
|
Search recursively in {directory} (which defaults to the current
|
||
|
|
directory) for filenames matching the {pattern}. Behaves just like the
|
||
|
|
|:grep| command, but will open the |Quickfix| window for you.
|
||
|
|
|
||
|
|
:AckHelp[!] [options] {pattern} *:AckHelp*
|
||
|
|
|
||
|
|
Search vim documentation files for the {pattern}. Behaves just like the
|
||
|
|
|:Ack| command, but searches only vim documentation .txt files
|
||
|
|
|
||
|
|
:LAckHelp [options] {pattern} *:LAckHelp*
|
||
|
|
|
||
|
|
Just like |:AckHelp| but instead of the |quickfix| list, matches are placed
|
||
|
|
in the current |location-list|.
|
||
|
|
|
||
|
|
:AckWindow[!] [options] {pattern} *:AckWindow*
|
||
|
|
|
||
|
|
Search all buffers visible in the screen (current tab page only) files for
|
||
|
|
the {pattern}.
|
||
|
|
|
||
|
|
:LAckWindow [options] {pattern} *:LAckWindow*
|
||
|
|
|
||
|
|
Just like |:AckWindow| but instead of the |quickfix| list, matches are
|
||
|
|
placed in the current |location-list|.
|
||
|
|
|
||
|
|
Files containing the search term will be listed in the split window, along
|
||
|
|
with the line number of the occurrence, once for each occurrence. <Enter> on
|
||
|
|
a line in this window will open the file, and place the cursor on the matching
|
||
|
|
line.
|
||
|
|
|
||
|
|
Note that if you are using Dispatch.vim with |g:ack_use_dispatch|, location
|
||
|
|
lists are not supported, because Dispatch does not support them at this time.
|
||
|
|
`:LAck` versions of commands above will give a warning and proceed to use the
|
||
|
|
quickfix list instead.
|
||
|
|
|
||
|
|
See http://beyondgrep.com/ for more information on searching with ack.

|
|
g:ack_use_dispatch
|
||
|
|
Default: 0
|
||
|
|
|
||
|
|
Use this option to use vim-dispatch to run searches in the background, with a
|
||
|
|
variety of execution backends for different systems.
|
||
|
|
|
||
|
|
Due to limitations in Dispatch at this time, location lists are unsupported
|
||
|
|
and result windows will appear before results are ready. Still, these may be
|
||
|
|
acceptable tradeoffs for very large projects where searches are slow.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
>
|
||
|
|
let g:ack_use_dispatch = 1

<
|
||
|
|
*g:ack_use_cword_for_empty_search*
|
||
|
|
g:ack_use_cword_for_empty_search
|
||
|
|
Default: 1
|
||
|
|
|
||
|
|
Use this option to enable blank searches to run against the word under the
|
||
|
|
cursor. When this option is not set, blank searches will only output an error
|
||
|
|
message.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
>
|
||
|
|
let g:ack_use_cword_for_empty_search = 0
|
||
|
|
<

MAPPINGS *ack-mappings*
|
||
|
|
|
||
|
|
The following keyboard shortcuts are available in the |quickfix| and
|
||
|
|
|location-list| windows:
|
||
|
|
|
||
|
|
? display a quick summary of these mappings.
|
||
|
|
|
||
|
|
o open file (same as Enter).
|
||
|
|
|
||
|
|
O open file and close the quickfix window.
|
||
|
|
|
||
|
|
go preview file (open but maintain focus on ack.vim results).
|
||
|
|
|
||
|
|
t open in a new tab.
|
||
|
|
|
||
|
|
T open in new tab without moving to it.
|
||
|
|
|
||
|
|
h open in horizontal split.
|
||
|
|
|
||
|
|
H open in horizontal split, keeping focus on the results.
|
||
|
|
|
||
|
|
v open in vertical split.
|
||
|
|
|
||
|
|
gv open in vertical split, keeping focus on the results.
|
||
|
|
|
||
|
|
q close the quickfix window.
|
||
|
|
|
||
|
|
To adjust these, see |g:ack_mappings|.

Ignoring files *ack-ignore*
|
||
|
|
|
||
|
|
If you're using this plugin with ag, The Silver Searcher, bear in mind that:
|
||
|
|
|
||
|
|
- It ignores file patterns from your .gitignore and .hgignore.
|
||
|
|
|
||
|
|
- If there are other files in your source repository you don't wish to
|
||
|
|
search, you can add their patterns to an .agignore file.

ISSUES AND FAQ *ack-issues-and-faq*
|
||
|
|
|
||
|
|
I don't want to jump to the first result automatically.~
|
||
|
|
|
||
|
|
Use `:Ack!`, with bang. If you want this behavior most of the time, you
|
||
|
|
might like an abbreviation or mapping in your personal config, something
|
||
|
|
like these:
|
||
|
|
>
|
||
|
|
cnoreabbrev Ack Ack!
|
||
|
|
nnoremap <Leader>a :Ack!<Space>
|
||
|
|
<
|
||
|
|
Most of the `:[L]Ack*` commands support this. Note that this behavior
|
||
|
|
follows the convention of Vim's built-in |:grep| and |:make| commands.
|
||
|
|
|
||
|
|
I use NERDTree and opening ack.vim results in a vertical split displacing it.~
|
||
|
|
|
||
|
|
You are probably using NERDTree with its default alignment at the left
|
||
|
|
side of the window. Set these custom mappings in your vimrc to work around
|
||
|
|
this:
|
||
|
|
>
|
||
|
|
let g:ack_mappings = {
|
||
|
|
\ 'v': '<C-W><CR><C-W>L<C-W>p<C-W>J<C-W>p',
|
||
|
|
\ 'gv': '<C-W><CR><C-W>L<C-W>p<C-W>J' }
|
||
|
|
<
|
||
|
|
This solution will be improved in the future.
|
||
|
|
|
||
|
|
Results show a mix of relative and absolute paths, making them hard to read.~
|
||
|
|
|
||
|
|
This is a quirk of Vim that can happen with plain |:vimgrep| too. You can
|
||
|
|
try this in your vimrc to work around it:
|
||
|
|
>
|
||
|
|
autocmd BufAdd * exe "cd" fnameescape(getcwd())
|
||
|
|
<
|
||
|
|
but for some users this may be disruptive to their Vim workflow. For more
|
||
|
