The bash auto-completion bundled with ack-grep adds an extra space after the
slash. E.g., if _ is the cursor:
$ ack-grep foo /home_<tab>
results in
$ ack-grep foo /home/ _
This means that pressing tab again will give auto-complete options from the
current working directory instead of /home/. Compare with the auto-completion
for ls:
$ ls /ho_<tab>
$ ls /home/_
Apparently the fix is as simple as changing the two lines at the bottom for
this:
complete -F _ack $filenames ack
complete -F _ack $filenames ack-grep
And then:
$ source /etc/bash_completion
However before I found that simple solution I spent some time cleaning up this
file and I ended up with the attached file. I believe it works as the previous
one, if not better, but this is the second time I play with Bash
auto-completion, so I cannot be sure. I based my changes on
/etc/bash_completion.d/findutils and the completion for ls, rmdir, etc in
/etc/bash_completion. One small advantage of my version is that when Bash shows
the alternative completions for a directory it only shows one slash at the end,
where the current version (with the $filenames fix) shows two, which works but
looks ugly. E.g., mine:
$ ack-grep foo /etc/<tab>
acpi// group- papersize
Current:
/etc/acpi /etc/localtime
Note that my proposed version shows relative paths, which saves screen state.
