I noted that when it is invoked used with --recurse-submodules, the result is not as expected for the submodules. I get submodules results as if no files were modified (like --cached option) although I would expect results taking into account the modifications. Expected behavior: git grep --recurse-submodules string: - git grep string // search into main repo - for each submodule, git grep string // search into submodule Actual behavior: git grep --recurse-submodules string: - git grep string // search into main repo - for each submodule, git grep --cached string // search into submodule Do you get the same behavior?

It seems git-grep was taking into account the worktree modifications in submodules before f9ee2fc ("grep: recurse in-process using 'struct repository'", 02-08-2017). I'm not sure, thought, if this behavior change was a bug during the conversion or a project decision.

Thanks. In this case, I am not sure if the comment here really helps.

It seems that git-grep was taking the worktree into account before f9ee2fc ("grep: recurse in-process using 'struct repository'", 02-08-2017).
