2010-02-05Revert 30816237 and 7e62265Libravatar Junio C Hamano1-40/+0
It seems that we have bad interaction with the code related to GIT_WORK_TREE and "grep --no-index", and broke running grep inside the .git directory. For now, just revert it and resurrect it after 1.7.0 ships. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2010-01-25grep: expose "status-only" feature via -qLibravatar Junio C Hamano1-2/+14
Teach "git grep" a new "-q" option to report the presense of a match via its exit status without showing any output, similar to how "grep -q" works. Internally "grep" engine already knew this "status-only" mode of operation because it needed to grep inside log message to filter commits when called from the "git log" machinery, and this patch only exposes it to the command line tool. A somewhat unfair benchmark in the Linux kernel directory shows a dramatic improvement: (with patch) $ time ../git.git/git grep -q linux HEAD ; echo $? real 0m0.030s user 0m0.004s sys 0m0.004s 0 (without patch) $ time git grep linux HEAD >/dev/null; echo $? real 0m4.432s user 0m4.272s sys 0m0.076s 0 This is "somewhat unfair" because I knew a file with such a string comes very early in the tree traversal (namely, ".gitignore").

2010-01-18grep: NUL terminate input from a fileLibravatar Jim Meyering1-0/+1
Internally "git grep" runs regexec(3) that expects its input string to be NUL terminated. When searching inside blob data, read_sha1_file() automatically gives such a buffer, but builtin-grep.c forgot to put the NUL at the end, even though it allocated enough space for it.

2010-01-15grep --no-index: allow use of "git grep" outside a git repositoryLibravatar Junio C Hamano1-0/+26
Just like some people wanted diff features that are not found in other people's diff implementations outside of a git repository and added --no-index mode to the command, this adds --no-index mode to the "git grep" command. Also, inside a git repository, --no-index mode allows you to grep in untracked (but not ignored) files. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-01-15grep: prepare to run outside of a work treeLibravatar Junio C Hamano1-0/+7
This moves the call to setup_git_directory() for running "grep" from the "git" wrapper to the implementation of the "grep" subcommand. A new variable "use_index" is always true at this stage in the series, and when it is on, we require that we are in a directory that is under git control. To make sure we die the same way, we make a second call into setup_git_directory() when we detect this situation. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2010-01-12grep: -L should show empty filesLibravatar Junio C Hamano1-2/+0
The -L (--files-without-match) option is supposed to show paths that produced no matches. When running the internal grep on work tree files, however, we had an optimization to just return on zero-sized files, without doing anything. This optimization doesn't matter too much in practice (a tracked empty file must be rare, or there is something wrong with your project); to produce results consistent with GNU grep, we should stop the optimization and show empty files as not having the given pattern.

2009-07-22grep: Add --max-depth option.Libravatar Michał Kiedrowicz1-10/+46
It is useful to grep directories non-recursively, e.g. when one wants to look for all files in the toplevel directory, but not in any subdirectory, or in Documentation/, but not in Documentation/technical/. This patch adds support for --max-depth <depth> option to git-grep. If it is given, git-grep descends at most <depth> levels of directories below paths specified on the command line. Note that if path specified on command line contains wildcards, this option makes no sense, e.g. $ git grep -l --max-depth 0 GNU -- 'contrib/*' (note the quotes) will search all files in contrib/, even in subdirectories, because '*' matches all files.

2009-07-01grep: add option -p/--show-functionLibravatar René Scharfe1-3/+5
The new option -p instructs git grep to print the previous function definition as a context line, similar to diff -p. Such context lines are marked with an equal sign instead of a dash. This option complements the existing context options -A, -B, -C. Function definitions are detected using the same heuristic that diff uses. User defined regular expressions are not supported, yet.

2009-07-01grep: print context hunk marks between filesLibravatar René Scharfe1-0/+11
Print a hunk mark before matches from a new file are shown, in addition to the current behaviour of printing them if lines have been skipped. The result is easier to read, as (presumably unrelated) matches from different files are separated by a hunk mark. GNU grep does the same.

2009-03-17grep: prefer builtin over external one when coloring resultsLibravatar Nguyễn Thái Ngọc Duy1-0/+2

2009-03-07grep: add support for coloring with external grepsLibravatar René Scharfe1-0/+36
Add the config variable color.grep.external, which can be used to switch on coloring of external greps. To enable auto coloring with GNU grep, one needs to set color.grep.external to --color=always to defeat the pager started by git grep. The value of the config variable will be passed to the external grep only if it would colorize internal grep's output, so automatic terminal detected works. The default is to not pass any option, because the external grep command could be a program without color support. Also set the environment variables GREP_COLOR and GREP_COLORS to pass the configured color for matches to the external grep. This works with GNU grep; other variables could be added as needed.

Coloring matches makes them easier to spot in the output. Add two options and two parameters: color.grep (to turn coloring on or off), color.grep.match (to set the color of matches), --color and --no-color (to turn coloring on or off, respectively).
