SVN -- recursive diffs

It's odd that svn (source control) doesn't have an easy way to see the entire evolution of a file. Since I'm usually wondering how and when something was changed, or just want to see the progression of the changes.

So I just wrote a quick shell script to do this:


#!/bin/bash

# 2008 GPL

if [[ $1 == "" ]]
then

echo "SVN RECURSIVE DIFF"
echo ""
echo "This script will list all svn changes to a file"
echo "the first and last file in the repository"
echo "and a series of diffs that connect them."
echo "IE, you can see the complete evolution of the file."
echo "It's probably best to pipe the output to a file."
echo ""
echo "USE"
echo " svnrdiff "
echo ""
echo "EXAMPLE"
echo " svnrdiff Model/ModelExample.cs > somefile.txt"
echo ""
echo "NOTES"
echo ""
echo "If your log is out of date, use"
echo ""
echo " svn up"
echo ""
echo "If you just want to see who last touched a line, use"
echo ""
echo " svn praise "
exit

fi

v1=""
v2=""
show_current="0"

while read log
do

echo ===================================================================
echo $log
echo ===================================================================

# grab revision numbers of file
v1=$( echo $log | sed -e 's/^r//' -e 's/ .*//' -e 's/-//g' )

if [[ $v2 != "" ]]
then

# print succesive diffs
svn diff -r $v2:$v1 $1

show_current="1"

else

# print first file
svn cat -r $v1 $1

fi

v2=$v1

# list in cronological order (tac)
done < <( svn log $1 | grep -E -e "^r[0-9]+ \| " | tac )

# print last file (if haven't already)
echo ===================================================================
echo "Current snapshot:"
echo ===================================================================
if [[ $show_current == "1" ]]
then
svn cat $1
else
echo "Same as above."
fi

Elephant paints self-portrait

Wow this elephant is terrible. He draws the feet directly on top of the ground rather than inset. Doesn't he know anything about linear perspective???? :)

Barack Obama investigated over ties to Kevin Bacon

The Obama campaign went on the defensive this week, playing down reports that the Illinois Senator was linked to popular Hollywood Icon, and "bad boy" Kevin Bacon. In a prepared statement, Obama responded that many people are in fact linked to the controversial figure, and that he both "rejected" and "denounced" the support of Bacon.

Bacon was not available for comment.

Looks like a giant species of star fish has been found. These guys would look better with faces. I propose that we tattoo faces on all star fish:
