René Scharfe 7e8f59d577 grep: color patterns in output
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.

[-f <file>] [-e] <pattern>
[--and|--or|--not|(|)|-e <pattern>...] [<tree>...]
[--] [<path>...]
DESCRIPTION
-----------
Look for specified patterns in the working tree files, blobs
registered in the index file, or given tree objects.
OPTIONS
-------
--cached::
Instead of searching in the working tree files, check
the blobs registered in the index file.
-a::
--text::
Process binary files as if they were text.
-i::
--ignore-case::
Ignore case differences between the patterns and the
files.
-I::
Don't match the pattern in binary files.
-w::
--word-regexp::
Match the pattern only at word boundary (either begin at the
beginning of a line, or preceded by a non-word character; end at
the end of a line or followed by a non-word character).
-v::
--invert-match::
Select non-matching lines.
-h::
-H::
By default, the command shows the filename for each
match. `-h` option is used to suppress this output.
`-H` is there for completeness and does not do anything
except it overrides `-h` given earlier on the command
line.
--full-name::
When run from a subdirectory, the command usually
outputs paths relative to the current directory. This
option forces paths to be output relative to the project
top directory.
-E::
--extended-regexp::
-G::
--basic-regexp::
Use POSIX extended/basic regexp for patterns. Default
is to use basic regexp.
-F::
--fixed-strings::
Use fixed strings for patterns (don't interpret pattern
as a regex).
-n::
Prefix the line number to matching lines.
-l::
--files-with-matches::
--name-only::
-L::
--files-without-match::
Instead of showing every matched line, show only the
names of files that contain (or do not contain) matches.
For better compatibility with 'git-diff', --name-only is a
synonym for --files-with-matches.
-z::
--null::
Output \0 instead of the character that normally follows a
file name.
-c::
--count::
Instead of showing every matched line, show the number of
lines that match.
--color::
Show colored matches.
--no-color::
Turn off match highlighting, even when the configuration file
gives the default to color output.
-[ABC] <context>::
Show `context` trailing (`A` -- after), or leading (`B`
-- before), or both (`C` -- context) lines, and place a
line containing `--` between contiguous groups of
matches.
-<num>::
A shortcut for specifying -C<num>.
-f <file>::
Read patterns from <file>, one per line.
-e::
The next parameter is the pattern. This option has to be
used for patterns starting with - and should be used in
scripts passing user input to grep. Multiple patterns are
combined by 'or'.
--and::
--or::
--not::
( ... )::
Specify how multiple patterns are combined using Boolean
expressions. `--or` is the default operator. `--and` has
higher precedence than `--or`. `-e` has to be used for all
patterns.
--all-match::
When giving multiple pattern expressions combined with `--or`,
this flag is specified to limit the match to files that
have lines to match all of them.
`<tree>...`::
Search blobs in the trees for specified patterns.
\--::
Signals the end of options; the rest of the parameters
are <path> limiters.
Example
-------
git grep -e \'#define\' --and \( -e MAX_PATH -e PATH_MAX \)::
Looks for a line that has `#define` and either `MAX_PATH` or
`PATH_MAX`.
git grep --all-match -e NODE -e Unexpected::
Looks for a line that has `NODE` or `Unexpected` in
files that have lines that match both.
