From e94fb4404280c07a668b4669c072983cdd079592 Mon Sep 17 00:00:00 2001 From: Denton Liu Date: Wed, 24 Mar 2021 01:36:27 -0700 Subject: git-completion.bash: pass $__git_subcommand_idx from __git_main() Many completion functions perform hardcoded comparisons with $cword. This fails in the case where the main git command is given arguments (e.g. `git -C . bundle` would fail to complete its subcommands). Even _git_worktree(), which uses __git_find_on_cmdline(), could still fail. With something like `git -C add worktree move`, the subcommand would be incorrectly identified as "add" instead of "move". Assign $__git_subcommand_idx in __git_main(), where the git subcommand is actually found and the corresponding completion function is called. Use this variable to replace hardcoded comparisons with $cword.

Now that it's a builtin, we can take advantage of the groundwork laid out by parse-options and use the generated options. Rewrite _git_stash() to take use __gitcomp_builtin() to generate completions for subcommands. The main `git stash` command does not take any arguments directly. If no subcommand is given, it automatically defaults to `git stash push`. This means that we can simplify the logic for when no subcommands have been given yet. We only have to offer subcommand completions when we're completing a non-option after "stash". One area that this patch could improve upon is that the `git stash list` command accepts log-options. It would be nice if the completion for this were unified with that of _git_log() and _git_show() which would allow completions to be provided for options such as `--pretty` but that is outside the scope of this patch.
