A script to cycle through all the modified files in subversion repository to see the diffs in gvim. Tested with subversion 1.6. Depending on the version of subversion, you may need to modify cut command to get the exact file name.

#!/usr/bin/env bash

# Make a list of all the modified files in local subversion repository
# in current directory. Cycle throuh all the files and ask if you want
# to see the diff.

# Uses svnvimdiff command created by Geoff Buchan which can be found at

svn st  				|
    grep "^M"				|
	  cut -c9- 			|
	    while read file;
            do 
	    	echo -ne "View diff of $file? (y/n)\n"
		# -s option for echo off
		# read from stdin otherwise reads from the file in
		# loop i.e. gets the new line from file in i 
		read -s -n 1 answer <&1
		case $answer in
		    [Yy] )  svnvimdiff -g $file
		            ;;
		    *    )  ;;
		esac
	    done

I would like to always see the diffs in gvim opened in maximum possible size to fit the screen. For that I have modified svnvimdiff script to take "~/.gvimfullscreenrc" file as RC file instead of ~/.vimrc.

svnvimdiff before change:

if [[ $1 == "-g" ]] ; then
vimdiff="gvimdiff -f"
shift 1
fi

After changes:

if [[ $1 == "-g" ]] ; then

Make it a full screen diff

vimdiff="gvimdiff -f -U ~/.gvimfullscreenrc"
shift 1
fi

Added following lines to ~/.vimrc to make it open in max. possible size and created ~.gvimfullscreenrc:

" The following lines are added so that gvim opens in max possible size
" on a given screen. This helps in diff commands (svnvimdiff) so that we
" can see the diff on whole screen
if has('gui_running')
set lines=1024
set columns=256
