commit message conventions

A set of scripts for analyzing commit messages on Github.

Analyses

  • imperative (add)
  • gerund (adding)
  • past simple (added)
  • present simple, 3rd person (adds)
• word frequency
• commit message length, number of lines
• beginning with a capital letter
• ending with a dot
• containing only ASCII characters
• written with CAPS LOCK on

Dependencies

pip install -r requirements.txt

Running

Run the scripts in the following order

./process_verbs.py && ./process_irregular_verbs.py && ./generate_conjugations.py && ./fetch_commits.py yyyy-mm-dd-hh && ./analyze.py && ./plot.py

You can substitute fetch_commits.py yyyy-mm-dd-hh with fetch_commits_for_month.py yyyy-mm or ./fetch_commits_for_year.py yyyy.

Results

I analyzed commits from the whole 2017, you can with the charts inside the results-2017 folder.
