" Vim global plugin for doing single or multipatch code reviews"{{{ " Version : 0.1 "{{{ " Last Modified : Thu 25 May 2006 10:15:11 PM PDT " Author : Manpreet Singh (junkblocker AT yahoo DOT com) " Copyright : 2006 by Manpreet Singh " License : This file is placed in the public domain. " " History : 0.1 - First released "}}} " Documentation: "{{{ " =========================================================================== " This plugin allows single or multipatch code reviews to be done in VIM. Vim " has :diffpatch command to do single file reviews but can not handle patch " files containing multiple patches. This plugin provides that missing " functionality and doesn't require the original file to be open. " " Installing: "{{{ " " For a quick start... " " Requirements: "{{{ " " 1) (g)vim 7.0 or higher built with +diff option. " 2) patch and patchutils ( http://cyberelk.net/tim/patchutils/ ) installed " for your OS. For windows it is availble from Cygwin ( " http://www.cygwin.com ) or GnuWin32 ( http://gnuwin32.sourceforge.net/ " ). ""}}} " Install: "{{{ " " 1) Extract this in your $VIM/vimfiles or $HOME/.vim directory and restart " vim. " " 2) Make sure that you have filterdiff from patchutils and patch commands " installed. " " 3) Optinally, specify the locations to filterdiff and patch commands and " location of a temporary directory to use in your .vimrc. " " let g:patchreview_filterdiff = '/path/to/filterdiff' " let g:patchreview_patch = '/path/to/patch' " let g:patchreview_tmpdir = '/tmp/or/something' " " 4) Optionally, generate help tags to use help " " :helptags ~/.vim/doc " or " :helptags c:\vim\vimfiles\doc ""}}} ""}}} " Usage: "{{{ " " :PatchReview path_to_submitted_patchfile [optional_source_directory] " " after review is done " " :PatchReviewCleanup " " See :help patchreview for details after you've created help tags.
