2011-08-01grep: long context optionsLibravatar René Scharfe1-4/+4
Take long option names for -A (--after-context), -B (--before-context) and -C (--context) from GNU grep and add a similar long option name for -W (--function-context). Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-08-01grep: add option to show whole function as contextLibravatar René Scharfe1-1/+4
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.

2011-06-05grep: add --headingLibravatar René Scharfe1-0/+2
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 Documentation/git-grep.txt 154:--heading:: t/t7810-grep.sh 785:test_expect_success 'grep --heading' ' 786: git grep --heading -e char -e lo_w hello.c hello_world >actual && 808: git grep --break --heading -n --color \ Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2011-06-05grep: fix coloring of hunk marks between filesLibravatar René Scharfe1-7/+16
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. Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2011-05-10grep: use get_pathspec() correctlyLibravatar Junio C Hamano1-7/+1
When there is no remaining string in argv, get_pathspec(prefix, argv) will return a two-element array that has prefix as the first element, so there is no need to re-roll that logic in the code that uses get_pathspec(). Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-05-09git-grep: do not die upon -F/-P when grep.extendedRegexp is set.Libravatar Junio C Hamano1-13/+43
The previous one made "git grep -P" fail when grep.extendedRegexp is enabled. That is a no-starter. The option on the command line should just make the command ignore the configured default. The handling of "-F" in the existing code has the same problem. Instead of saying -G/-F/-E/-P incompatible with each other, just allow the last one win. That way, you can have "[alias] gr = grep -P" and use Pcre for everyday work e.g. "git gr ':i?foo'", and append -G to the aliased command line to override it e.g. "git gr -G '[Ff][Oo][Oo]'".

2011-05-09git-grep: Bail out when -P is used with -F or -ELibravatar Michał Kiedrowicz1-1/+3
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`.

2011-05-09git-grep: Learn PCRELibravatar Michał Kiedrowicz1-0/+2
This patch teaches git-grep the --perl-regexp/-P options (naming borrowed from GNU grep) in order to allow specifying PCRE regexes on the command line. PCRE has a number of features which make them more handy to use than POSIX regexes, like consistent escaping rules, extended character classes, ungreedy matching etc. git isn't build with PCRE support automatically. USE_LIBPCRE environment variable must be enabled (like `make USE_LIBPCRE=YesPlease`). Signed-off-by: Michał Kiedrowicz <michal.kiedrowicz@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

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.

2011-03-25Improve tree_entry_interesting() handling codeLibravatar Nguyễn Thái Ngọc Duy1-6/+6
t_e_i() can return -1 or 2 to early shortcut a search. Current code may use up to two variables to handle it. One for saving return value from t_e_i temporarily, one for saving return code 2. The second variable is not needed. If we make sure the first variable does not change until the next t_e_i() call, then we can do something like this: int ret = 0; while (...) { if (ret != 2) { ret = t_e_i(); if (ret < 0) /* no longer interesting */ break; if (ret == 0) /* skip this round */ continue; } /* ret > 0, interesting */ } Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2011-03-16standardize brace placement in struct definitionsLibravatar Jonathan Nieder1-2/+1
In a struct definitions, unlike functions, the prevailing style is for the opening brace to go on the same line as the struct name, like so: struct foo { int bar; char *baz; }; Indeed, grepping for 'struct [a-z_]* {$' yields about 5 times as many matches as 'struct [a-z_]*$'.

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.
