grep -p: support user defined regular expressions

2009-07-02T02:16:50Z

Respect the userdiff attributes and config settings when looking for lines with function definitions in git grep -p. Signed-off-by: Rene Scharfe Signed-off-by: Junio C Hamano

grep: add option -p/--show-function

2009-07-02T02:16:49Z

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.

grep: print context hunk marks between files

2009-07-02T02:16:46Z

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. Signed-off-by: Rene Scharfe Signed-off-by: Junio C Hamano

grep: move context hunk mark handling into show_line()

2009-07-02T02:16:45Z

Move last_shown into struct grep_opt, to make it available in show_line(), and then make the function handle the printing of hunk marks for context lines in a central place. Signed-off-by: Rene Scharfe Signed-off-by: Junio C Hamano

grep: use parseopt

2009-05-09T07:29:56Z

Convert git-grep to parseopt. The bitfields in struct grep_opt are converted to full ints, increasing its size. This shouldn't be a problem as there is only a single instance in memory. Signed-off-by: Rene Scharfe Signed-off-by: Junio C Hamano

grep: add support for coloring with external greps

2009-03-07T19:34:59Z

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.

grep: color patterns in output

2009-03-07T19:34:59Z

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). The output of external greps is not changed. This patch is based on earlier ones by Nguyễn Thái Ngọc Duy and Thiago Alves. Signed-off-by: Rene Scharfe Signed-off-by: Junio C Hamano

grep: remove grep_opt argument from match_expr_eval()

2009-03-07T19:34:56Z

The only use of the struct grep_opt argument of match_expr_eval() is to pass the option word_regexp to match_one_pattern(). By adding a pattern flag for it we can reduce the number of function arguments of these two functions, as a cleanup and preparation for adding more in the next patch.

grep: don't call regexec() for fixed strings

2009-01-10T05:35:56Z

Add the new flag "fixed" to struct grep_pat and set it if the pattern is doesn't contain any regex control characters in addition to if the flag -F/--fixed-strings was specified. This gives a nice speed up on msysgit, where regexec() seems to be extra slow. Before (best of five runs): $ time git grep grep v1.6.1 >/dev/null real 0m0.552s user 0m0.000s sys 0m0.000s $ time git grep -F grep v1.6.1 >/dev/null real 0m0.170s user 0m0.000s sys 0m0.015s With the patch: $ time git grep grep v1.6.1 >/dev/null real 0m0.173s user 0m0.000s sys 0m0.000s The difference is much smaller on Linux, but still measurable.

git grep: Add "-z/--null" option as in GNU's grep.

2008-10-01T16:14:54Z

Here's a trivial patch that adds "-z" and "--null" options to "git grep". It was discussed on the mailing-list that git's "-z" convention should be used instead of GNU grep's "-Z". So things like 'git grep -l -z "$FOO" | xargs -0 sed -i "s/$FOO/$BOO/"' do work now. Signed-off-by: Raphael Zimmerer Signed-off-by: Shawn O. Pearce
