custom preprocessing steps: filters?

[bjdmeest]

So, I kind of miss the latex macro's but I'm pretty sure it's easy to include them.

Stuff like registering custom shortcuts, so that I can write a small regex so that

And then I will make X\todo.

gets changed to

And then I will make X*.*{:.todo}.

Would adding a custom filter be appropriate for this? Are there resources available for including custom preprocessing filters to a paper repo?

I'm wondering if there would be a clean, simple and generic way to define such shortcuts...

But for now, this would indeed be possible with a custom filter.
You can add these filters to this block in your Rules file (order-sensitive).

You can find more information on how to create filters in the nanoc documentation, or in the built-in filters.
