In order to make an auto title plugin for markata I needed to come up with a way to reverse the slug of a post to create a title for one that does not explicitly have a title.

!!! Note "slugs" a slug is generally all lowercase and free of spaces, and is a way to make website routes (urls)

Here I have a path available that gives me the articles path, ex. python-reverse-sluggify.md. An easy way to get rid of the file extension, is to pass it into pathlib.Path and ask for the stem, which returns python-reverse-sluggify. Then from There I chose to replace - and _ with a space.

article["title"] = (
    Path(article["path"]).stem.replace("-", " ").replace("_", " ").title()
)

To turn this into a markata plugin I put it into a pre_render hook.

from pathlib import Path

from markata.hookspec import hook_impl, register_attr

@hook_impl @register_attr("articles") def pre_render(markata) -> None: for article in markata.filter('title==""'): article["title"] = ( Path(article["path"]).stem.replace("-", " ").replace("_", " ").title() )
