Total Changed: + 71 - 80 Code Changed: + 16 - 65 Test Changed: + 55 - 15
If you had just the Total Changed line, you'd think that this commit wasn't very special. With the categorization, you can see that the commit had a large boost in the quality of the code, replacing a large chunk of code with fewer lines and adding many (probably missing) lines of test.
I then wrote a second script using the changes to the commit email so I could collect statistics on the whole of a commiter's work:
Author: eric
Change: Code 8022 22238 -14216
Change: Config 13 498 -485
Change: Other 93415 125369 -31954
Change: Test 1668 6666 -4998
Change: Total 104444 156387 -51943
Change: WWW 323 613 -290The columns are added - removed, added, removed. (I have a huge number of Other because I've been adding all the machine configuration files, major cheating!) Comparing just added lines, I'm 3:1 code:test, comparing 'live' lines, I'm 5:1.
My next step will be to turn this into a graph so that its easier to visualize how the code has changed over time.
