Git has hall the niceness baked in for fixing conflicts with kdiff3

git mergetool --tool kdiff3

and you are away. svn in lacking in these regards. The below script automates some of this process.

fixconflicts.rb

#!/bin/ruby
`svn status | grep ^C`.each_line() do |file|
    file.gsub!(/^C\s*/,"").strip!
    leftright = `ls #{file}.r*`.split.collect { |c| c.strip }
    versions = leftright.sort
    left = versions[0]
    right = versions[1]
    working = "#{file}.mine"
    cmd = "kdiff3 -m --auto -o #{file} #{left} #{right} #{working}"
    puts cmd
    puts `#{cmd}`
    puts "Resolve y/n"
    yn = gets
    if yn = /y/
        `svn resolved #{file}`
    end
 end

Run the script from your sandbox root and it will load kdiff3 to fix all of your conflicts from the merge. Pretty simple but it makes my life a lot easier.
