Script to colorize svn/git blame output

The purpose of this script is to add some highlighting to the output of the blame function. All lines from the same commit receive the same color. Because the number of colors available is limited, it is not possible to assign a unique color to each commit. However, I believe that even a couple of colors can be useful in displaying what blocks of code were changed together.

The easiest way to install this script is to invoke it through docker. Add the following to your .bashrc.

alias color_svn_blame="docker run --rm \
                                  -i \
                                  kyokley/color_blame \
                                  color_svn_blame"
alias color_git_blame="docker run --rm \
                                  -i \
                                  kyokley/color_blame \
                                  color_git_blame"

For svn:

$ svn blame FILENAME | color_svn_blame | less

For git:

$ git blame FILENAME | color_git_blame | less
