Using __git_find_on_cmdline() to find subcommands and case "$subcommand,$cur" to limit the number of nested case statements is as idiomatic as you can get in the completion script. And I hear you, that "<path> first, <refname> second" syntax makes it way too complicated, especially since they can follow '-b <refname>'. I wrote a completion function for 'git worktree' as well, turns out a week or two before you posted this, but I never submitted it as it was way too convoluted.

Anyway, will send it in reply to this, just for reference. And here it is. From the number of indentation levels and comment lines you can see why I haven't submitted this patch yet :) OTOH it offers refs for -b and -B, and there are only fairly narrow corner cases when 'git --options' can fool it (but that's a general issue with __git_find_on_cmdline(), I wouldn't go into that). contrib/completion/git-completion.bash | 59 ++++++++++++++++++++++++++++++++++ 1 file changed, 59 insertions(+) diff --git a/contrib/completion/git-completion.bash b/contrib/completion/git-completion.bash index c97c648d7e..20a17e2c50 100644 --- a/contrib/completion/git-completion.bash +++ b/contrib/completion/git-completion.bash @@ -2564,6 +2564,65 @@ _git_whatchanged () _git_log } +_git_worktree () +{ + local subcommand subcommand_idx sc c=1 + local subcommands="add prune" + + while [ $c -lt $cword ] && [ -z "$subcommand" ]; do + for sc in $subcommands; do + if [ "$sc" = "${words[c]}" ]; then + subcommand=$sc + subcommand_idx=$c + break + fi + done + ((c++)) + done + + case "$subcommand,$cur" in + ,*) + __gitcomp "$subcommands" + ;; + add,--*) + __gitcomp "--detach" + ;; + add,*) + case "$prev" in + -b|-B) + __gitcomp_nl "$(__git_refs)" + ;; + -*) # $prev is an option without argument: have to complete + # the path for the new worktree, fall back to bash + # filename completion + ;; + *) # $prev is not an option, so it must be either the + # 'add' subcommand, an argument of an option (e.g. + # branch for -b|-B), or the path for the new worktree + if [ $cword -eq $((subcommand_idx+1)) ]; then + # right after the 'add' subcommand, have to + # complete the path + : + else + case "${words[cword-2]}" in + -b|-B) # after '-b <branch>', have to complete + # the path + ;; + *) # after the path, have to complete the + # branch to be checked out + __gitcomp_nl "$(__git_refs)" + ;; + esac + fi + ;; + esac + ;; + prune,--*) + __gitcomp "--dry-run --verbose --expire" + ;; + esac +} + __git_main () { local i c=1 command __git_dir -- 2.5.0.418.gdd37a9b ^ permalink raw reply related [flat|nested] 6+ messages in thread

As a person who never uses git-completion (or git-prompt), I wasn't aware of that, so thanks for the heads-up. I only installed completion (and prompt) when I decided to work on this (and I don't think I've used tab-completion since then). >>>> + ;; >>>> + add,*) >>>> + while [ $c -lt $cword ]; do >>>> + case "${words[c]}" in >>>> + --*) ;; >>>> + -[bB]) ((refpos++)) ;; >>>> + *) ((n++)) ;; >>>> + esac >>>> + ((c++)) >>>> + done >>>> + if [ $n -eq $refpos ]; then > > I suppose here you wanted to calculate where (i.e. at which word on > the command line) we should offer refs and fall back to bash builtin > filename completion otherwise. It works well in the common cases, > but: > > - it doesn't offer refs after -b or -B That was intentional since this is a new branch name, so it didn't seem sensible to offer completion of existing refs. On the other hand, it doesn't make much since to offer pathname completion either, but I didn't see a better alternative. On reflection, I suppose ref completion can make sense if the new branch name is going to be similar to an existing one. > - it gets fooled by options to the git command, e.g. 'git > --git-dir=.git worktree add <TAB>' offers refs instead of files, > 'git --git-dir=.git worktree add ../some/path <TAB>' offers > refs, etc. This shortcoming could be addressed by computing relative to the subcommand-index as your version does, correct? I don't have enough background with the (git-specific) completion facility to be able to judge if this patch and approach has merit and ought to be pursued further, or if it would be better to drop in favor of (some version of) your patch. I don't care strongly, and am fine with dropping this patch if it's approach is suboptimal. >>>> + __gitcomp_nl "$(__git_refs)" >>>> + fi >>>> + ;; >>>> + prune,--*) >>>> + __gitcomp "--dry-run --verbose --expire" >>>> + ;; >>>> + esac >>>> + fi >>>> +} >>>> + ^ permalink raw reply [flat|nested] 6+ messages in thread
