Re: [Python-markdown-discuss] Preprocessor after Treeprocessor?

[Waylan L. <wa...@gm...>]

Jake,

As explained in the API docs [1], every processor is set to run in a
certain order. If you insert your preprocessor before all others, then
it is being run first.

Without seeing your code, it is hard to know for sure, but my guess it
that perhaps your preprocessor is inserting the code block as raw html
(in <pre><code> tags). If so, then your code blocks are being treated
as raw html and stored in the htmlStash until they are swapped back in
by a postprocessor. In other words, they never see treeprocessors and
therefore never get exposed to codehilite. Instead, you preprocessor
should be inserting the code block using markdown formatting (indented
at least four spaces). Then markdown will process the code block as
usual.

I hope that helps.
