b8ffedca6f grep: load funcname patterns for -W
git-grep avoids loading the funcname patterns unless they are needed.
ba8ea74 (grep: add option to show whole function as context,
2011-08-01) forgot to extend this test also to the new funcbody
feature.  Do so.

The catch is that we also have to disable threading when using
userdiff, as explained in grep_threads_ok().  So we must be careful to
introduce the same test there.

ba8ea7496f grep: add option to show whole function as context
Add a new option, -W, to show the whole surrounding function of a match.

It uses the same regular expressions as -p and diff to find the beginning
of sections.

Currently it will not display comments in front of a function, but those
that are following one.  Despite this shortcoming it is already useful,
e.g. to simply see a more complete applicable context or to extract whole
functions.

93d5e0c208 t7810: avoid unportable use of "echo"
Michael J Gruber noticed that under /bin/dash this test failed
(as is expected -- \n in the string can be interpreted by the
command), while it passed with bash.  We probably could work it
around by using backquote in front of it, but it is safer and
more readable to avoid "echo" altogether in a case like this.

1d84f72ef1 grep: add --heading
With --heading, the filename is printed once before matches from that
file instead of at the start of each line, giving more screen space to
the actual search results.

This option is taken from ack (http://betterthangrep.com/).  And now
git grep can dress up like it:

	$ git config alias.ack "grep --break --heading --line-number"

	$ git ack -e --heading

08303c3636 grep: fix coloring of hunk marks between files
Commit 431d6e7b (grep: enable threading for context line printing)
split the printing of the "--\n" mark between results from different
files out into two places: show_line() in grep.c for the non-threaded
case and work_done() in builtin/grep.c for the threaded case.  Commit
55f638bd (grep: Colorize filename, line number, and separator) updated
the former, but not the latter, so the separators between files are
not colored if threads are used.

This patch merges the two.  In the threaded case, hunk marks are now
printed by show_line() for every file, including the first one, and the
very first mark is simply skipped in work_done().  This ensures that the
output is properly colored and works just as well.

d0042abe14 git-grep: Fix problems with recently added tests
Brian Gernhardt reported that test 'git grep -E -F -G a\\+b' fails on
OS X 10.6.7. This is because I assumed \+ is part of BRE, which isn't
true on all platforms.

The easiest way to make this test pass is to just update expected
output, but that would make the test pointless. Its real purpose is to
check whether 'git grep -E -F -G' is different from 'git grep -E -G -F'.
To check that, let's change pattern to "a+b*c". This should return
different match for -G, -F and -E.

I also made two small tweaks to the tests. First, I added path "ab" to
all calls to future-proof tests. Second, I updated last two tests to
better show that 'git grep -P -E' is different from 'git grep -E -P'.

While at it, add some generic tests for grep.extendedRegexp config option,

258a618849 git-grep: Bail out when -P is used with -F or -E
This patch makes git-grep die() when -P is used on command line together
with -E/--extended-regexp or -F/--fixed-strings.

This also makes it bail out when grep.extendedRegexp is enabled.

But `git grep -G -P pattern` and `git grep -E -G -P pattern` still work
because -G and -E set opts.regflags during parse_options() and there is
no way to detect `-G` or `-E -G`.

b22520a37c grep: allow -E and -n to be turned on by default via configuration
Add two configration variables grep.extendedRegexp and grep.lineNumbers to
allow the user to skip typing -E and -n on the command line, respectively.

Scripts that are meant to be used by random users and/or in random
repositories now have use -G and/or --no-line-number options as
appropriately to override the settings in the repository or user's
~/.gitconfig settings. Just because the script didn't say "git grep -n" no
longer guarantees that the output from the command will not have line
numbers.

a48fcd8369 tests: add missing &&
Breaks in a test assertion's && chain can potentially hide
failures from earlier commands in the chain.

Commands intended to fail should be marked with !, test_must_fail, or
test_might_fail.  The examples in this patch do not require that.

2010-09-29 13:49:57 -07:00
Junio C Hamano
5aaeb733f5 log --author: take union of multiple "author" requests
In the olden days,

    log --author=me --committer=him --grep=this --grep=that

used to be turned into:

    (OR (HEADER-AUTHOR me)
        (HEADER-COMMITTER him)
        (PATTERN this)
        (PATTERN that))

showing my patches that do not have any "this" nor "that", which was
totally useless.

80235ba ("log --author=me --grep=it" should find intersection, not union,
2010-01-17) improved it greatly to turn the same into:

    (ALL-MATCH
      (HEADER-AUTHOR me)
      (HEADER-COMMITTER him)
      (OR (PATTERN this) (PATTERN that)))

That is, "show only patches by me and committed by him, that have either
this or that", which is a lot more natural thing to ask.

We however need to be a bit more clever when the user asks more than one
"author" (or "committer"); because a commit has only one author (and one
committer), they ought to be interpreted as asking for union to be useful.
The current implementation simply added another author/committer pattern
at the same top-level for ALL-MATCH to insist on matching all, finding
nothing.

Turn

    log --author=me --author=her \
    	--committer=him --committer=you \
	--grep=this --grep=that

into

    (ALL-MATCH
      (OR (HEADER-AUTHOR me) (HEADER-AUTHOR her))
      (OR (HEADER-COMMITTER him) (HEADER-COMMITTER you))
      (OR (PATTERN this) (PATTERN that)))

instead.

678e484b7d grep: Add the option '--open-files-in-pager'
This adds an option to open the matching files in the pager, and if the
pager happens to be "less" (or "vi") and there is only one grep pattern,
it also jumps to the first match right away.

The short option was chose as '-O' to avoid clashes with GNU grep's
options (as suggested by Junio).

So, 'git grep -O abc' is a short form for 'less +/abc $(grep -l abc)'
except that it works also with spaces in file names, and it does not
start the pager if there was no matching file.

[jn: rebased and added tests; with error handling fix from Junio
squashed in]
