post-commit hook to generate a changelog page for your Jekyll site

Last year I decided to make my blog private, it enables me to have private sections accessible only to those who have the url.
Yet, I missed some of the transparency history provided by public repositories and opted for an in-between solution :

• for each commit of type feat or fix a line is added on the Changelog page
• some filepaths can be kept secret by not reporting related commits
• although Changelog page additions are automated, commiting it is a task left to human operator

All you need is to add a sentinel to an empty Changelog page like so :

--- layout: page title: Changelog permalink: /changelog --- <!-- Edit below -->

And copy this git post-commit hook in your Jekyll repository :

That’s it, you now have a semi-automated Changelog page.
