Add 'repo grep' to support searching all projects
Users can now use 'repo grep' to search all projects, rather than 'repo forall -c git grep'. Its not only shorter to type, but it also filters results better by highlighting which projects matched in the client workspace. Signed-off-by: Shawn O. Pearce <sop@google.com>

Search for the specified patterns in all project files.
|
||||
|
||||
Options
|
||||
-------
|
||||
|
||||
The following options can appear as often as necessary to express
|
||||
the pattern to locate:
|
||||
|
||||
-e PATTERN
|
||||
--and, --or, --not, -(, -)
|
||||
|
||||
Further, the -r/--revision option may be specified multiple times
|
||||
in order to scan multiple trees. If the same file matches in more
|
||||
than one tree, only the first result is reported, prefixed by the
|
||||
revision name it was found under.
|
||||
|
||||
Examples
|
||||
-------
|
||||
|
||||
Look for a line that has '#define' and either 'MAX_PATH or 'PATH_MAX':
|
||||
|
||||
repo grep -e '#define' --and -\( -e MAX_PATH -e PATH_MAX \)
|
||||
|
||||
Look for a line that has 'NODE' or 'Unexpected' in files that
|
||||
contain a line that matches both expressions:
|
||||
|
||||
repo grep --all-match -e NODE -e Unexpected
