Vim: keep location list window open after selecting a file

I need exactly the opposite behavior of this question. My observation is that upon pressing enter on a line in location list window, the window will be closed and the main window will display the content of the selected file. As a contrary, quickfix window doesn't have this behavior, i.e., it remains opened after the selection.

I have checked my autocmd and there is no special handling for location list or quickfix list.

An example - :lgrep hi * to populate the location list. lopen to open the location list window. Press enter on any line.

Use :cw to get quickfix window. It will appear horizontally split to current window. and :ccl to return back to selected result

Syntastic and the location-list window

Syntastic by default closes the location list window when no errors are present. Therefore if you use something like :lgrep which does not mark any of the results as errors then the location-list window will close once you leave the location-list window, e.g. like using <cr> to jump to a location.

Syntastic provides a way to tweak this via g:syntastic_auto_loc_list variable. Setting this to 0 will disable the auto-close functionality.

Set the following in your vimrc file:

let g:syntastic_auto_loc_list = 0

To learn more about this variable see: :h 'syntastic_auto_loc_list'.

Generic Vim debugging

Often the easiest way to test if your vimrc or a plugin is causing problem is it compare the functionality to a vanilla vim config (or at least more vanilla). Do this by starting up Vim without a vimrc. I use the following invocation:

vim -N -u NONE

Once you have started up Vim in this manner you can test for you bug and see if it is present.

  • If the bug is still present then it that means it is probably a part of Vim nature or a bug with Vim itself. In this case I suggest you do more read the documentation via :h :help, :h :helpgrep, and :h bug-reports
  • If the bug is not present then the error is occurring due to something in your vimrc or plugin. This often means you need to disable portions of your vimrc/plugins to try and find the culprit. A fast way is to use a binary search.

Slightly more complicated debugging with :verbose

Often a bug is easier to track down directly by using :verbose to see where something was last set. (See :h :verbose)

  • Mappings will display were they are last set. e.g. :verbose nmap <leader>foo. See :h :map-verbose and :h map-listing.
  • Settings will display where they were last set as well. e.g. :verbose set shiftwidth. See :h :set-verbose.
  • Autocomd's will display where they are last defined. e.g. :verbose autocmd BufEnter. See :h :autocmd-verbose and :h autocmd-list.

Advanced debugging with 'verbosefile'

Another way to debug something is to use 'verbose'/:verbose and 'verbosefile' to effectively log what Vim is doing.

Example of using :verbose and 'verbosefile' to debug your bug.

  • Do :lgrep command
  • Open location-list window via :lopen
  • Set 'verbosefile' via :set verbosefile=~/verbose.txt
  • :15verbose normal <c-v><cr>
  • Now open the log file via :sp ~/verbose.txt
  • Search the log file for anything suspicious. e.g. close or lclose in your case
  • Once found it will show you the autocmd or function that is causing the closing.
  • If autocmd look to revise it.
  • If a function you may need to look at :scriptnames to figure out which file the is associated with script local functions. See :scriptnames and :h <SID>.

I find using Tim Pope's scriptease.vim makes this process easier by providing the :Verbose command which will setup 'verbosefile' for you as well as open it right afterwards in the preview window. Scriptease also provides a nice wrapper around :scriptnames via :Scriptnames. In general scriptease.vim provides many helpful methods to debugging and reloading plugins.
