R4 is a project mainly written in Python, based on the MIT license.
Wrapper around p4 command-line client to add extra functionality and ease-of-use.

r4 is a wrapper around the Perforce command-line tool, p4,
that adds extra functionality. You can use r4 in the same way you
use p4, except there are some new commands available.
I wrote r4 because I wanted the equivalent of Subversion's status
command.
To use r4, you need to first build and install the Perforce
Python API (which requires you to download the Perforce C++ API).
Usage::
r4 grep [ -i ] [ -l ] [ -v ] pattern file[revRange]...
Searches the named files for lines containing a match to the given pattern. By default, grep prints the matching lines.
The pattern can be a Perl-style regular expression.
If a file is specified without a revision, then all revisions of the file are searched.
Example::
$ r4 grep ALL Makefile //depot/project/Makefile#1: ALL := tools //depot/project/Makefile#2: ALL := tools scripts //depot/project/Makefile#3: ALL := tools scripts tests //depot/project/Makefile#5: ALL := tools scripts tests
You can use revision specifiers and revision ranges to control which revisions of a file will be searched.
Examples::
r4 grep pattern file#head r4 grep pattern file#4 r4 grep pattern file#12,20 r4 grep pattern file@release_4
Note that Perforce wildcards can be used, giving the ability to do recursive greps.
Examples::
r4 grep pattern ./... r4 grep pattern ./.../file
The -i/--ignore-case flag causes the matching to be done while
ignoring case distinctions.
The -l/--files-with-matches flag suppresses normal output and
instead just prints the names of each file from which output would
normally have been printed. File names are printed with revision
specifiers or revision ranges indicating which revisions of the file
contain matches.
Example::
$ r4 grep -l ALL Makefile //depot/project/Makefile#1,9 //depot/project/Makefile#11
The -v/--invert-match flag inverts the sense of matching, to
select non-matching lines.
Usage::
status [ --no-ignore ] [ path ... ]
Lists all locally modified files under the specified paths (if no paths are supplied the current working directory is used).
The --no-ignore flag forces files that are ignored because they
matched a pattern in a .r4ignore file to be printed with an 'I'
prefix.
The first column in the output is one character wide, and indicates the file's status:
========= ====== Character Status
? Item is not under version control A Added D Deleted M Modified O Opened for editing--may be unchanged, branched or integrated I Ignored (only with --no-ignore) ========= ======
r4 does not support the general p4 options that come before
the command--options like -p to specify a different port, -u
to specify a user, etc.
