How can I tell counsel's `counsel-git` to ignore certain file endings and folders

Question

I am using counsel-git to find and open files.

Is there any way to ignore folders and files that are ending with specific pattern.

For example: ignore folders named: .idea ; and files ended with *.save and *.xml or specific as -i or .gitignore. All the folders starting with . always show up on top; I just want to ignore some of them which I do not use.

config file:

(ivy-mode 1)
(setq ivy-use-virtual-buffers t)
(setq enable-recursive-minibuffers t)

(global-set-key (kbd "C-c g") 'counsel-git)

Answer 1

counsel-git is calling counsel-git-cands to build the list of files.
counsel-git-cands is running the shell command, which is stored in variable counsel-git-cmd, which has the value "git ls-files -z --full-name --".

So you have two different options:

1. modify the result of function counsel-git-cands to remove files from the list, you do not want. i.e. add an advice, which filters the results: (advice-add 'counsel-git-cands :filter-return #'my-filter-counsel-git-cands). Read more about advicing at the elisp manual.
2. change the shell command line git ls-files.... to sort out files you do not want. i.e. by using the command line option --exclude. You need to experiment with git ls-files a bit with that here. Read man page of git-ls-files (1).
