Revert "completion: don't declare 'local words' to make zsh happy"
git-completion: fix regression in zsh support
completion: move private shopt shim for zsh to __git_ namespace
completion: don't declare 'local words' to make zsh happy
The zsh support of git-completion script in contrib/ is broken for current
versions of zsh, and does not notice when there's a subcommand.
For example: "git log origi<TAB>" gives no completions because it would
try to find a "git origi..." command. This will be fixed by zsh 4.3.12,
but for now we can workaround it by backporting the same fix as zsh folks
implemented.
The problem started after commit v1.7.4-rc0~11^2~2 (bash: get
--pretty=m<tab> completion to work with bash v4), which introduced
_get_comp_words_by_ref() that comes from bash-completion[1] scripts, and
relies on the 'words' variable.
However, it turns out 'words' is a special variable used by zsh
completion. From zshcompwid(1):
[...] the parameters are reset on each function exit (including nested
function calls from within the completion widget) to the values they had
when the function was entered.
As a result, subcommand words are lost. Ouch.
This is now fixed in the latest master branch of zsh[2] by simply defining
'words' as hidden (typeset -h), which removes the special meaning inside
the emulated bash function. So let's do the same.

Most zsh users probably probably do not expect a custom shopt function
to enter their environment just because they ran "source
~/.git-completion.sh".
Such namespace pollution makes development of other scripts confusing
(because it makes the bash-specific shopt utility seem to be available
in zsh) and makes git's tab completion script brittle (since any other
shell snippet implementing some other subset of shopt will break it).
Rename the shopt shim to the more innocuous __git_shopt to be a good
citizen (with two underscores to avoid confusion with completion rules
for a hypothetical "git shopt" command).

The "_get_comp_words_by_ref -n := words" command from the
bash_completion library reassembles a modified version of COMP_WORDS
with ':' and '=' no longer treated as word separators and stores it in
the ${words[@]} array. Git's programmable tab completion script uses
this to abstract away the difference between bash v3's and bash v4's
definitions of COMP_WORDS (bash v3 used shell words, while bash v4
breaks at separator characters); see v1.7.4-rc0~11^2~2 (bash: get
--pretty=m<tab> completion to work with bash v4, 2010-12-02).
zsh has (or rather its completion functions have) another idea about
what ${words[@]} should contain: the array is prepopulated with the
words from the command it is completing. For reasons that are not
well understood, when git-completion.bash reserves its own "words"
variable with "local words", the variable becomes empty and cannot be
changed from then on. So the completion script neglects the arguments
it has seen, and words complete like git subcommand names. For
example, typing "git log origi<TAB>" gives no completions because
there are no "git origi..." commands.
However, when this words variable is not declared as local but is just
populated by _get_comp_words_by_ref() and then read in various
completion functions, then zsh seems to be happy about it and our
completion script works as expected.
So, to get our completion script working again under zsh and to
prevent the words variable from leaking into the shell environment
under bash, we will only declare words as local when using bash.

In v1.7.4-rc0~11^2~2 (bash: get --pretty=m<tab> completion to work
with bash v4, 2010-12-02) we started to use _get_comp_words_by_ref()
to access completion-related variables. That was large change, and to
make it easily reviewable, we invoked _get_comp_words_by_ref() in each
completion function and systematically replaced every occurance of
bash's completion-related variables ($COMP_WORDS and $COMP_CWORD) with
variables set by _get_comp_words_by_ref().
This has the downside that _get_comp_words_by_ref() is invoked several
times during a single completion. The worst offender is perhaps 'git
log mas<TAB>': during the completion of 'master'
_get_comp_words_by_ref() is invoked no less than six times.
However, the variables $prev, $cword, and $words provided by
_get_comp_words_by_ref() are not modified in any of the completion
functions, and the previous commit ensures that the $cur variable is
not modified as well. This makes it possible to invoke
_get_comp_words_by_ref() to get those variables only once in our
toplevel completion functions _git() and _gitk(), and all other
completion functions will inherit them.

Since v1.7.4-rc0~11^2~2 (bash: get --pretty=m<tab> completion to work
with bash v4, 2010-12-02) we use _get_comp_words_by_ref() to access
completion-related variables, and the $cur variable holds the word
containing the current cursor position in all completion functions.
This $cur variable is left unchanged in most completion functions;
there are only four functions modifying its value, namely __gitcomp(),
__git_complete_revlist_file(), __git_complete_remote_or_refspec(), and
_git_config().
If this variable were never modified, then it would allow us a nice
optimisation and cleanup. Therefore, this patch assigns $cur to an
other local variable and uses that for later modifications in those
four functions.

While doing a final sanity check before merging a topic Bsomething, it
is a good idea to review what damage Bsomething branch would make, by
running:
$ git diff ...Bsomething
Unfortunately, our completion script for 'git diff' doesn't offer
anything after '...'. This is because 'git diff's completion function
invokes __git_complete_file() for non-option arguments to complete the
'<tree>:<path>' extended SHA-1 notation, but this helper function
doesn't support refs after '...' or '..'. Completion of refs after
'...' or '..' is supported by the __git_complete_revlist() helper
function, but that doesn't support '<tree>:<path>'.
To support both '...<ref>' and '<tree>:<path>' notations for 'git
diff', this patch, instead of adding yet another helper function,
joins __git_complete_file() and __git_complete_revlist() into the new
common function __git_complete_revlist_file(). The old helper
functions __git_complete_file() and __git_complete_revlist() are
changed to be a direct wrapper around the new
__git_complete_revlist_file(), because they might be used in
user-supplied completion scripts and we don't want to break them.
This change will cause some wrong suggestions for other commands which
use __git_complete_file() ('git diff' and friends) or
__git_complete_revlist() ('git log' and friends), e.g. 'git diff
...master:Doc<TAB>' and 'git log master:Doc<TAB>' will complete the
path to 'Documentation/', although neither commands make any sense.
However, both of these were actively wrong to begin with as soon as
the user entered the ':', so there is no real harm done.

Bash's programmable completion provides the COMP_WORDS array variable,
which holds the individual words in the current command line. In bash
versions prior to v4 "words are split on shell metacharacters as the
shell parser would separate them" (quote from bash v3.2.48's man
page). This behavior has changed with bash v4, and the command line
"is split into words as readline would split it, using COMP_WORDBREAKS
as" "the set of characters that the readline library treats as word
separators" (quote from bash v4's man page).
Since COMP_WORDBREAKS contains the characters : and = by default, this
behavior change in bash affects git's completion script. For example,
before bash 4, running
$ git log --pretty=m <tab><tab>
would give a list of pretty-printing formats starting with 'm' but now
it completes on branch names.
It would be possible to work around this by removing '=' and ':' from
COMP_WORDBREAKS, but as noticed in v1.5.6.4~9^2 (bash completion:
Resolve git show ref:path<tab> losing ref: portion, 2008-07-15), that
would break *other* completion scripts. The bash-completion library
includes a better workaround: the _get_comp_words_by_ref function
re-assembles a copy of COMP_WORDS, excluding a collection of word
separators of the caller's choice. Use it.
As a bonus, this also improves behavior when tab is pressed with the
cursor in the middle of a word.
To avoid breaking setups with the bash-completion library not already
loaded, if the _get_comp_words_by_ref function is not defined then a
shim that just reads COMP_WORDS will be used instead (no change from
the current behavior in that case).

(files or refs), if any.
The code responsible for completing subcommand looks different
compared to the completion functions of other git commands with

comes before the subcommand (i.e. git notes --ref <notes-ref> add).

Modify git-completion.bash so that it also works with zsh when using
bashcompinit. In particular:
declare -F
Zsh doesn't have the same 'declare -F' as bash, but 'declare -f'
is the same, and it works just as well for our purposes.
${var:2}
Zsh does not implement ${var:2} to skip the first 2 characters, but
${var#??} works in both shells to replace the first 2 characters
with nothing. Thanks to Jonathan Nieder for the suggestion.
for (( n=1; "$n" ... ))
Zsh does not allow "$var" in arithmetic loops. Instead, pre-compute
the endpoint and use the variables without $'s or quotes.
shopt
Zsh uses 'setopt', which has a different syntax than 'shopt'. Since
'shopt' is used infrequently in git-completion, we provide
a bare-bones emulation.
emulate -L bash
KSH_TYPESET
Zsh offers bash emulation, which turns on a set of features to
closely resemble bash. In particular, this enables SH_WORDSPLIT,
which splits scalar variables on word boundaries in 'for' loops.
We also need to set KSH_TYPESET, to fix "local var=$(echo foo bar)"
issues.
The last set of options are turned on only in _git and _gitk. Some of
the sub-functions may not work correctly if called directly.
