builtin-grep: make pieces of it available as library. This makes three functions and associated option structures from builtin-grep available from other parts of the system. * options to drive built-in grep engine is stored in struct grep_opt; * pattern strings and extended grep expressions are added to struct grep_opt with append_grep_pattern(); * when finished calling append_grep_pattern(), call compile_grep_patterns() to prepare for execution; * call grep_buffer() to find matches in the in-core buffer. This also adds an internal option "status_only" to grep_opt, which suppresses any output from grep_buffer(). Callers of the function as library can use it to check if there is a match without producing any output. Signed-off-by: Junio C Hamano <junkio@cox.net>

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.

git-grep: Learn PCRE 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>

log --author/--committer: really match only with name part When we tried to find commits done by AUTHOR, the first implementation tried to pattern match a line with "^author .*AUTHOR", which later was enhanced to strip leading caret and look for "^author AUTHOR" when the search pattern was anchored at the left end (i.e. --author="^AUTHOR"). This had a few problems: * When looking for fixed strings (e.g. "git log -F --author=x --grep=y"), the regexp internally used "^author .*x" would never match anything; * To match at the end (e.g. "git log --author='google.com>$'"), the generated regexp has to also match the trailing timestamp part the commit header lines have. Also, in order to determine if the '$' at the end means "match at the end of the line" or just a literal dollar sign (probably backslash-quoted), we would need to parse the regexp ourselves. An earlier alternative tried to make sure that a line matches "^author " (to limit by field name) and the user supplied pattern at the same time. While it solved the -F problem by introducing a special override for matching the "^author ", it did not solve the trailing timestamp nor tail match problem. It also would have matched every commit if --author=author was asked for, not because the author's email part had this string, but because every commit header line that talks about the author begins with that field name, regardleses of who wrote it. Instead of piling more hacks on top of hacks, this rethinks the grep machinery that is used to look for strings in the commit header, and makes sure that (1) field name matches literally at the beginning of the line, followed by a SP, and (2) the user supplied pattern is matched against the remainder of the line, excluding the trailing timestamp data.

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.

"log --author=me --grep=it" should find intersection, not union Historically, any grep filter in "git log" family of commands were taken as restricting to commits with any of the words in the commit log message. However, the user almost always want to find commits "done by this person on that topic". With "--all-match" option, a series of grep patterns can be turned into a requirement that all of them must produce a match, but that makes it impossible to ask for "done by me, on either this or that" with: log --author=me --committer=him --grep=this --grep=that because it will require both "this" and "that" to appear. Change the "header" parser of grep library to treat the headers specially, and parse it as: (all-match-OR (HEADER-AUTHOR me) (HEADER-COMMITTER him) (OR (PATTERN this) (PATTERN that) ) ) Even though the "log" command line parser doesn't give direct access to the extended grep syntax to group terms with parentheses, this change will cover the majority of the case the users would want. This incidentally revealed that one test in t7002 was bogus. It ran: log --author=Thor --grep=Thu --format='%s' and expected (wrongly) "Thu" to match "Thursday" in the author/committer date, but that would never match, as the timestamp in raw commit buffer does not have the name of the day-of-the-week.

grep: Add --max-depth option. 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.

log --author/--committer: really match only with name part When we tried to find commits done by AUTHOR, the first implementation tried to pattern match a line with "^author .*AUTHOR", which later was enhanced to strip leading caret and look for "^author AUTHOR" when the search pattern was anchored at the left end (i.e. --author="^AUTHOR"). This had a few problems: * When looking for fixed strings (e.g. "git log -F --author=x --grep=y"), the regexp internally used "^author .*x" would never match anything; * To match at the end (e.g. "git log --author='google.com>$'"), the generated regexp has to also match the trailing timestamp part the commit header lines have. Also, in order to determine if the '$' at the end means "match at the end of the line" or just a literal dollar sign (probably backslash-quoted), we would need to parse the regexp ourselves. An earlier alternative tried to make sure that a line matches "^author " (to limit by field name) and the user supplied pattern at the same time. While it solved the -F problem by introducing a special override for matching the "^author ", it did not solve the trailing timestamp nor tail match problem. It also would have matched every commit if --author=author was asked for, not because the author's email part had this string, but because every commit header line that talks about the author begins with that field name, regardleses of who wrote it. Instead of piling more hacks on top of hacks, this rethinks the grep machinery that is used to look for strings in the commit header, and makes sure that (1) field name matches literally at the beginning of the line, followed by a SP, and (2) the user supplied pattern is matched against the remainder of the line, excluding the trailing timestamp data.
