[PATCH v2 00/45] completion: git-completion 1.3.3 patches

[Felipe Contreras]

completion: git-completion 1.3.1 patches

These patches represent what comprises git-completion 1.3.1, a friendly
fork I'm maintaining.

Some of these have already been sent, and should be in "seen", but for
some reason they are not [1]. Others have been sent, but probably won't
receive any review soon.

Since the patches for git-completion 1.3.0 the only differece is a
rebase on top of v2.31.0.

Cheers.

[PATCH v2 01/45] completion: fix __git_cmd_idx regression

[Felipe Contreras]

The commit 59d85a2a05 (git-completion.bash: use $__git_cmd_idx in more
places, 2021-04-22) caused a regression when using __git_complete and a
command relies on __git_cmd_idx.

We need the function wrapper to define __git_cmd_idx.

If the function wrapper defines __git_cmd_idx, then it's not necessary
for __git_zsh_main to do so.

I just realized this isn't 100% correct thanks to Fabian Wermelinger.
If we use __git_complete then the index should be 0. The above fixes the
annoying errors, but some commands don't complete correctly (e.g.
git_fetch).

I've sent an updated fix [1].

[PATCH v2 02/45] completion: bash: fix prefix detection in branch.*

[Felipe Contreras]

Otherwise we are completely ignoring the --cur argument.

The issue can be tested with:

  git clone --config=branch.<tab>

[PATCH v2 03/45] completion: fix for suboptions with value

[Felipe Contreras]

We need to ignore options that don't start with -- as well.

Depending on the value of COMP_WORDBREAKS, the last word could be
duplicated otherwise.

Can be tested with:

[PATCH v2 05/45] completion: bash: add correct suffix in variables

[Felipe Contreras]

__gitcomp automatically adds a suffix, but __gitcomp_nl and others
don't, we need to specify a space by default.

Can be tested with:

  git config branch.autoSetupMe<tab>

This fix only works for versions of bash greater than 4.0, before that
"local sfx" creates an empty string, therefore the unset expansion
doesn't work. The same happens in zsh.

Therefore we don't add the test for that for now.

The correct fix for all shells requires semantic changes in __gitcomp,
but that can be done later.

[PATCH v2 07/45] completion: zsh: trivial improvement

[Felipe Contreras]

$words has basically all the words we need, except the first one: git.

Lets simply add that instead of passing the original, which contains
options we don't want to pass downstream (like -c and -C).

[PATCH v2 08/45] completion: bash: do not modify COMP_WORDBREAKS

[Felipe Contreras]

There was no need for this once __git_reassemble_comp_words_by_ref() was
introduced. Now irrespective of the value of COMP_WORDBREAKS, words are
always joined together.

By default COMP_WORDBREAKS does contain a colon, and if it doesn't
somebody probably has a reason for it.

Completions are not supposed to modify COMP_WORDBREAKS and none of the
completions in the bash-completion project do.

We manually set it in Zsh so the Bash script is not confused.

[PATCH v2 12/45] completion: bash: remove non-append functionality

[Felipe Contreras]

There's no point in setting COMPREPLY only to override it later, and in
fact; we don't do that.

Therefore there's no functional difference between __gitcomp_direct()
and __gitcomp_direct_append(), since __gitcomp_direct() *always*
operates on empty COMPREPLY.

The same goes for __gitcomp_nl().

This patch makes the functionality of append and non-append functions
the same.

There should be no functional changes.

When we are typing configurations an = at the end signifies we still
want to type the value.

Can be tested with:

[PATCH v2 26/45] completion: simplify __gitcomp

[Felipe Contreras]

It's not possible for $cur_ to have anything more than --no- at this
point, so there's no need to add a suffix, nor check anything else.

All we are doing is checking that $cur_ matches --no, and adding a
completion if so.

This way the code reflects what we are doing.

[PATCH v2 27/45] completion: bash: change suffix check in __gitcomp

We don't match the prefix, we shouldn't match the suffix either.

There are no functional changes since all the callers that add a suffix
add an =, and if $cur_ ended with that suffix, we would return
immediately.

[PATCH v2 28/45] completion: improve __gitcomp suffix code

[Felipe Contreras]

There's no point in adding a suffix after a suffix.

If a suffix is provided, we add it, if not, then the default heuristic
is used.

There's no functional change since most callers don't specify a suffix,
and the ones that do use an =, which by default doesn't add an
additional suffix.

[PATCH v2 32/45] completion: add __gitcomp_opts

[Felipe Contreras]

[PATCH v2 37/45] completion: zsh: fix direct quoting

[Felipe Contreras]

Apparently using "compadd -Q" is almost always wrong, we want zsh to add
quoting when necessary. However, if we remove the -Q option, that would
make zsh add an extra "\ " at the end of some completions.

We can manually remove the spaces from the completions that have them,
and then add the suffix with the -S option, thus there's no more need
for the -Q option.

This makes completions like "stash@{0}" complete correctly:

  git stash show <tab>

[PATCH v2 40/45] completion: zsh: add correct removable suffix

[Felipe Contreras]

Zsh has a nice feature that allows a suffix to be automatically removed
if followed by a space.

For example:

  git log --prety=

If a space is typed, the suffix '=' is removed.

But we have to set the correct prefix first.

[PATCH v2 45/45] completion: bash: rename _get_comp_words_by_ref()

[Felipe Contreras]

is available.
