I did something similar a (very) long time ago (15 years back!), a static site generator and blog engine entirely coded in sh (yes, not even Bash) + coreutils. The idea was to use those scripts in git hooks, as they provide a template engine that allows to use the Git repository as a storage backend and publishing method, both for posts content (as file or as commit bodies) and for meta data about posts (author, date, etc). It was fun to build and got a few dozen users at the time, some even contributed small bugfixes and features :).
