Discussion: ideas for stored searches about tmux-copycat HOT 18 OPEN

Often people have the pwd on their bash prompt like so (fish truncates all but the last paths to one letter):

endrebak@havpryd ~/c/c/workflows>

I'd like some way of avoiding those in the file search, but dunno if that is possible.

Get commit hash in git log
set -g @copycat_search_WHATEVER '^commit[[:space:]]*'

from tmux-copycat.

Amazon jobflow ID
set -g @copycat_search_C-j 'j-[[:alnum:]]*'

from tmux-copycat.

I have a stored search for quoted text:
set -g @copycat_search_C-q '\"[^\"]*\"'

Frequently filenames, error messages and other important info are quoted in a program's output.

However, I'm unable to match single quotes, even escaping doesn't work. Is this a bug or am I doing it wrong?

@AnAppAMonth, interesting idea. Thanks for the submission.

I think a single quote searches could have a bug! I also just tried it and got an error.
Please open an issue with the description of what you tried. A pull request for this is also very welcome.

@ctjhoa improved the regex to match SHA1 hashes in every output format. See #73

Pull request for email address search over at #78

Get the last entry of a line if it is standard filename.

set -g @copycat_search_C-l '[a-zA-Z0-9_-./]+$'

This works for filenames without any path (basename - as for example for ls -l) and for git status if you are not in the root of the repo.

Can we have these searches in a way similar to vim-text-objects? That would make it much easier to remember and increase the key-combination space available to reduce clashes.

Match kubernetes objects
e.g. "asdf-gk8nr" or "asdf-foo-7bdcf85cf5-97x64"
set -g @copycat_search_C-k '[A-Za-z0-9-]+-[a-f0-9]{10}-[a-z0-9]{5}|[A-Za-z0-9-]+-[a-z0-9]{5}'

from tmux-copycat.

Match 32 bit or 64 bit addresses
e.g. "0xffffd53a", "0xffffd53affffd53a", "ffffd53a" or "ffffd53affffd53a"
set -g @copycat_search_a '0x[A-Fa-f0-9]{8}|0x[A-Fa-f0-9]{16}|[A-Fa-f0-9]{8}|[A-Fa-f0-9]{16}' # 32 or 64 bit adresses

from tmux-copycat.

The example here

set -g @copycat_search_G '\b[0-9a-f]{5,40}\b'

should be

set -g @copycat_search_G '\b[0-9a-f]{5}|[0-9a-f]{40}\b'

from tmux-copycat.

The search goes from bottom to top. Is there any way to search only the last command output (preferably from top to bottom)?

from tmux-copycat.

based on a quick search no. you would need to re-write or duplicate and change https://github.com/tmux-plugins/tmux-copycat/blob/master/scripts/copycat_generate_results.sh#L20

--

I guess you could use this somehow https://github.com/tmux-plugins/tmux-copycat/blob/master/scripts/copycat_jump.sh#L231
Use get_number_of_results to set initial jump position.

from tmux-copycat.

The "last entry" file search didn't work for me. The order of the regex was causing an issue:

set -g @copycat_search_C-f '[a-zA-Z0-9_./-]+$'

For the future reader, here's the issue reporting the single quote breakage.

I was not able to get the quoting snippet to work:

set -g @copycat_search_C-q "\"[^\"]*\""

It always selected the quotes incorrectly for me (if anyone knows why, I'd love to hear it):

@iloveitaly looks like you are on a mac.
Maybe you are not using GNU grep?

@iloveitaly I am on a mac, but changing the default grep installation would be a large-ish change since many other applications rely on the terrible grep version installed by default.

@iloveitaly

if you are on an M1 chip just do
export PATH=/opt/homebrew/opt/grep/libexec/gnubin/grep:$PATH"

on an x86-64 bit machine do
export PATH=/usr/local/opt/grep/libexec/gnubin:$PATH"

you can check what to export at

$ brew info grep
