Iterate through git commits to gather statistics

Installation

• clone this repository
• install Composer dependencies
• symlink the gitstats to your /usr/local/bin: ln -s /home/<you>/code/gitstats/gitstats /usr/local/bin/gitstats

Alternatively you can install the Composer package globally (composer global require mnapoli/gitstats)

Usage

• Add a .gitstats.yml file in your current directory:

tasks:
    'Commit message': "git log -1 --pretty=%B | head -n 1"
    'Commit author': "git log -1 --pretty=%an"
    'Number of files': "find . -type f | wc -l | xargs"
    'Number of directories': "find . -type d | wc -l | xargs"

• Run the application:

$ gitstats run <git-repository-url>

The repository will be cloned in a temporary directory. All tasks will be run against each commit. Ensure the repository doesn't contain modifications.

The output is formatted as CSV:

Commit,Date,Number of files,Number of directories

...

You can write the output to a file:

$ gitstats run <git-repository-url> > results.csv

You can then import that into a database or open it up with Excel or whatever.

MySQL

You can output the result as SQL queries to insert/update a MySQL table:

$ gitstats run <git-repository-url> --format=sql | mysql -u <user> -p <table>

Limit the number of commits processed

You can limit the number of commits to process using the --max parameter:

# Process only 100 commits
$ gitstats run <git-repository-url> --max=100

Show the progress

You can show a progress bar on stderr using the --progress parameter. When using that parameter it makes sense to redirect the output to a file or another command:

$ gitstats run <git-repository-url> --progress > file.csv
