Analyzing developers' commit relationship
Convert a number range to another range
http://stackoverflow.com/questions/929103/convert-a-number-range-to-another-range-maintaining-ratio
This code can do logging commits with variable options and placeholders. Especially, each commit in commites includes information such as commit ID(%h), author email(%ae), changeset(--numstat)
log_output = check_output(["git", "log", "--pretty=format:%h\t%ae", "--numstat", "--no-merges", "--since='1 years ago'"])
commits = [x.strip() for x in log_output.split('\n\n')]
print len(commits)For example, the last commit in commits was written by [email protected] and includes 1 add and 1 delete line which mostly means that 1 line is modified. Also the modified file is services/java/com/android/server/MountService.java
In [37]: commits[-1]
Out[37]: 'f503c8f\[email protected]\n1\t1\tservices/java/com/android/server/MountService.java'Reference: https://www.kernel.org/pub/software/scm/git/docs/git-log.html
Some exceptions
