This is already done by fish before calling the completion.
It breaks completion with combiners (#2025) and also with wrappers.
(This does not include git because that's better solved in #2145)
There are two main problems in the existing Fossil autocompletion that this
patch solves:
* Because Fossil lacks an alias system similar to those in Hg and Git,
wrapper scripts are common, and aliasing them to `fossil` is also fairly
common. The lack of the `command fossil` pattern in the completions script
meant that the actual fossil command might not be called, but rather the
alias. This problem has been fixed by introducing a __fish_fossil command,
similar to the __fish_hg and __fish_git commands in those completion shells,
that does this, and converting all explicit fossil calls in the completion
script to use __fish_fossil instead
* Because there's now a centralized location for calling Fossil, I also moved
all of the repetitive stderr redirects that function.
This results in more robust and cleaner code.
This was too simplistic, among other things it completed things that
looked like key ids but weren't, didn't turn "\x3a" back into
colons (which made the argument invalid)....
gpg is weird.
Might fix#2150
Bit one: Make all the fossil command invocations throw away stderr so we don't
get annoying messages when not in a repository.
Also:
- Move checkout into alphabetical order.
- Fix ls to complete against tags for -r option, not no option.
- Add missing option to delete command.
- Make commit complete against modified files.
- Make add only complete against extra files.
- Remove now ununused function to list extra & modified files.
- Add -f option in a number of places where it seemd appropriate.
__fish_complete_mime used in that way is a no-op on current fish anyway,
and emacs is by no means useful for just text files (it can also view
PDFs, images, ...).
Otherwise this completion currently only offers options, not arguments.
For most these are pretty much incompletable (lisp code, for example),
and for others it's just not all that useful.
