Can we customize the previewer commands?

[mmirus]

Hi there! Is it possible to configure the previewer commands for the finders the extension provides?

For example, it would be nice to be able to modify the git command used at https://github.com/aaronhallaert/advanced-git-search.nvim/blob/main/lua/advanced_git_search/git_utils.lua#L173-L187 when I run Telescope advanced_git_search diff_commit_file so that I can pass flags that customize the diff output provided by git to work better in this context, compared to how I want to see it when I run git directly in the terminal.

@mmirus If I understand correctly, you want to be able to configure flags for the git diff command?

[mmirus]

Exactly. For example, I have git configured to output diffs in a side-by-side view with delta. This works great when I'm viewing diffs directly in the terminal, but not inside a Telescope window. You can pass config flags to git to change that when you run git diff, and if the git commands used by the plugin were configurable, then I could pass those flags (perhaps they already are and I'm just missing how!).

@mmirus Ok great, can you give the linked pull request a try?
