Adding an explicit pre-processor would be great. They could turn commands such as {{today}} into the correct link (e.g. when you open a daily note, the title could be {{today}}, today would be rendered as 2020-06-08). Same could work for {{yesterday}} and {{tomorrow}}, {{this week}} and so on. Of course, having a general pre-processor goes beyond mere relative links, they could also be used for loading remote resources, or even running general scripts!

I would love this feature. I am migrating from Roam and really miss the `/today`, `/tomorrow` and `/yesterday` macros. Adding a preprocessor like this would be a lovely way to introduce the general functionality.

This would allow for some great template making.

Pre-processor feature is really missing in Obsidian. And also post-process with easy string replacing, because DOM manipulation is little bit overkill for some cases. Could you please bring this features as soon as possible? As I am also developer, I could help with that maybe.

It has been a couple of years, but it seems like it is possible: [Is there a pre-render pre-processor callback?](https://forum.obsidian.md/t/is-there-a-pre-render-pre-processor-callback/72530)

This is an old feature request.  
For basic user, this feature was implemented in the templates plugin.

For plugin developers see the thread link by pemperor.
