very slow shell when using theme on sshfs mounted git repository

[VietTralala]

I experience significant lag when using this theme on a sshfs-mounted directory inside a git repository. I used the command fish --profile FILE -c 'fish_prompt; type -q fish_right_prompt; and fish_right_prompt' for profiling as mentioned in another issue in the original fish-shell repo

The lag is negligible when using stock fish-shell without this theme.

Here is an excerpt of the profiling result

As one can see the git commands take quite some time. Thus I was wondering if one could exclude sshfs mounted directories from the additional git-functionality of this theme.

It is possible to exclude directories from the git features. But you might also be able to get it usable without completely disabling git. Showing dirty state and untracked files can be (very) slow on large network mounts. You can disable the dirty state flag and '...' output when there are untracked files,

…either globally via fish config:

set -g theme_display_git_dirty no
set -g theme_display_git_untracked no

…or locally via git repo config:

git config bash.showDirtyState false
git config bash.showUntrackedFiles false

I'd suggest doing it per-repo, via git config. Try each of those to see whether they resolve your issue.

If that doesn't solve your problem, you can use $theme_vcs_ignore_paths to completely ignore git/hg integration for a path:

set -g theme_vcs_ignore_paths /path/to/foo /path/to/bar

… or $theme_display_git to disable git integration entirely:

set -g theme_display_git no

I first thought about including the following lines into the head of the function __bobthefish_git_project_dir' which was defined in the file fish_prompt.fish

if test -z (df -P . | awk 'NR==2 {print$1}' | string match '/dev/*') 
     # if empty then return, since probably sshfs mount
     return
end

But your solution to set set -g theme_vcs_ignore_paths /path/to/foo/ /path/to/bar in the fish.config is way better and fully satisfies my needs.

Thank you for the fast and helpful response!

[vcfvct]

the git config bash.showDirtyState false && git config bash.showUntrackedFiles false works nicely for specific repo. Thank you!

none of the above suggestions make any difference for me I still get a several second delay before the prompt shows up, and it still shows "(master)"
