[PATCH 00/47] completion: git-completion 1.3 patches

[PATCH 00/47] completion: git-completion 1.3 patches

[Felipe Contreras]

These patches represent what comprises git-completion 1.3, 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. And others, particularly zsh improvements,
haven't been sent before.

A summary:

 * Tons of bugfixes
 * zsh: a bunch of improvements
 * zsh: an important fix regarding quoting
 * zsh: automatic suffix removal

The rest is reorganization, but it's still much needed.

I'm not anticipating these patches to be merged, I'm providing them in
case somebody is interested.

[PATCH 01/47] completion: bash: fix prefix detection in branch.*

Otherwise we are completely ignoring the --cur argument.

The issue can be tested with:

[PATCH 02/47] 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:

  git merge -X diff-algorithm=<tab>

[PATCH 04/47] 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 05/47] 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 09/47] 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.

[PATCH 17/47] completion: zsh: fix extra space on foo=

want to type the value.

Can be tested with:

  git -c log.d<tab>

[PATCH 23/47] 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 24/47] completion: bash: change suffix check in __gitcomp

[Felipe Contreras]

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 25/47] 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 26/47] completion: bash: simplify config_variable_name

Now that we can actually pass a suffix to __gitcomp function, and it
does the right thing, all the functions can receive the same suffix.

[PATCH 30/47] completion: bash: cleanup __gitcomp* invocations

[Felipe Contreras]

Some __gitcomp calls should be __gitcomp_nl, and vice versa.

No functional changes.

[PATCH 34/47] 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>

It's useful to specify specific suffixes for specific words.

[PATCH 37/47] 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 44/47] completion: bash: improve function detection

[Felipe Contreras]

 1. We should quote the argument
 2. We don't need two redirections
 3. A safeguard for arguments (-a) would be good

[PATCH 45/47] test: completion: add tests for __git_complete

[Felipe Contreras]

Even though the function was marked as not public, it's already used in
the wild.

We should at least test basic functionality.

[PATCH 46/47] completion: add proper public __git_complete

[Felipe Contreras]

When __git_complete was introduced, it was meant to be temporarily, while
a proper guideline for public shell functions was established
(tentatively _GIT_complete), but since that never happened, people
in the wild started to use __git_complete, even though it was marked as
not public.

Eight years is more than enough wait, let's mark this function as
public, and make it a bit more user-friendly.

So that instead of doing:

  __git_complete gk __gitk_main

The user can do:

  __git_complete gk gitk

And instead of:

  __git_complete gf _git_fetch

Do:

  __git_complete gf git_fetch

Backwards compatibility is maintained.
