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.

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

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

``` python
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()
        )
```
