Hi,

I want to implement something similar to ~~~~ expansion or the pipe-trick in internal links in an extension.

That is, I need to execute code - on save and preview only, - on wikitext ony, - on page content only, - before the pre-save-parser treats links in the wikitext, - altering the wikitext of the page.

I tried several hooks and ideas, but was unable to make it specific enough.

Help is appreciated.

Thank you.
