This gem will analyze every commit within a git repository using git log and libgit2/rugged. The following author statistics in relation to the git repository are collected and displayed:
- Total number of commits
- Total number of merge commits
- Total source line additions
- Total source line deletions
- Total file creates
- Total file deletes
- Total file renames
- Total file copies
This gem also uses grosser/language_sniffer to determine the language of each individual file within commits. This augments the reported statistics by breaking down the author's statistics by languages.
This gem also has the ability to save the acquired data into a JSON file (in either a compressed or pretty format). If a saved file is present for the repository you can use the gem to load the data from the file, thus saving time for re-displaying the statistics using a different set of display flags (what statistic to sort on, number of authors to show, consider merges, etc...). In the event that a repository updates with new commits the gem allows you to update the saved file with the new commits.
The following is the output produced by git_statistics --top 3 when used on the pengwynn/octokit (at commit 95a9de3) git repository. In this output we show the top three authors in rankings based on number of commits (merge commits are excluded from these results).
