Actually, can we have a follow-up patch to add in-code comment before the _get_comp_words_by_ref shell function in t9902 to explain why the test overrides this implementation detail? The script being tested will need to maintain _some_ invariants that is expected by this hack in order to keep the test working (or this hack needs to be updated when the updates to the completion script need to break the invariants), but without any explanation on what the invariants are, it is making it hard to others to update the completion script.

Anyway, thanks for pushing this forward. I have a bunch of tests for my __git_ps1() optimizations, but, being a bash function, I could never figure out how to integrate it with the test framework.

Why > override it here? Ah, ok, I think I got it. Of course, the words on the command line must be specified somehow to test completion functions. But the two implementations of _get_comp_words_by_ref() for bash and zsh in the completion script take the words on the command line from different variables, so we need a common implementation to test completion functions both on bash and zsh. Hence the _get_comp_words_by_ref() above, which takes the words on the command line and their count from $_words and $_cword, respectively, and run_completion() below, which fills those variables with its arguments. > > +print_comp () > > +{ > > + local IFS=$'\n' > > + echo "${COMPREPLY[*]}" > out > > +} > > + > > +run_completion () > > +{ > > + local -a COMPREPLY _words > > + local _cword > > + _words=( $1 ) > > + (( _cword = ${#_words[@]} - 1 )) > > + _git && print_comp > > +} ^ permalink raw reply [flat|nested] 21+ messages in thread

Well, yeah, that's one reason, but also I don't see the point in trying to fill the internal bash completion variables, maybe there would be some conflicts? Plus, the bash version of _get_comp_words_by_ref is rather complicated, so I decided to start with something simple that I could understand and see exactly what's going on. And for zsh I would definitely prefer to override _get_comp_words_by_ref than to mess with the internal variables, although I haven't found a way to test completion for zsh.

The tests are run in a non-interactive shell, which by default doesn't load bash completion with its complicated _get_comp_words_by_ref(). So these tests use _get_comp_words_by_ref() from git's completion script. Anyway, out of curiosity I quickly tried this on top of b8574ba7 (i.e. your patch from today's pu): diff --git a/t/t9902-completion.sh b/t/t9902-completion.sh index 3bbec79b..6c1ea956 100755 --- a/t/t9902-completion.sh +++ b/t/t9902-completion.sh @@ -27,27 +27,6 @@ complete () .

Yeah, we could explore that possibility later, as _get_comp_words_by_ref is part of the completion, and should be tested as well, otherwise we might be missing some bugs. However, I wonder if _get_comp_words_by_ref is needed at all. From what I can see it has to do with '--foo=bar' and 'foo:bar' completions, which in fact don't work correctly in zsh (I have patches for zsh to fix this though), but by modifying the code that checks for '--*=*' stuff we might be able to get rid of it, or at least the call to __git_reassemble_comp_words_by_ref. Right? Cheers. -- Felipe Contreras ^ permalink raw reply [flat|nested] 21+ messages in thread

I don't think the order is relevant, just that all the options are there, and the ones with arguments have a = in there, and the ones that don't, a space. -- Felipe Contreras ^ permalink raw reply [flat|nested] 21+ messages in thread

But it is relevant in the test: it fails if the order is changed either in the completion script or in the test. > and the ones with arguments have a = in there, and the ones > that don't, a space. Couldn't we check that better with a test or two for __gitcomp()? If a test for __gitcomp() fails, we would immediately have a fairly good idea where to look for the cause of the breakage. However, if this 'double dash "git checkout"' test fails, there are a bunch of other things that can possibly cause the failure. Patch comes in a minute.
