This is a Python-2.1 lexical scope issue, it works for me (Python-2.3).

However, as 2.1 must be supported, try that fix: The hdf argument must be propagated to the local def code_block(...). Simply add a new hdf argument to that def, and pass the hdf value from the enclosing scope.

The reStructuredText support could be even better if the #801 patch by tonib was applied… (after having done a quick check, it seems the patch also suffers from 2.1 compatibility issues)

thanks for the heads-up. with your help, i managed to get both WikiRestructuredText and WikiRestructuredTextLinks as well as some rst of my own to render without errors on python2.1. patch attached. there were some more instances of python2.1-incompatibilities (global name "env" not defined, True/False not defined, …). there might be some more, so it would be nice if someone could double-check this.

are there any guidelines for writing python2.1-compatible trac code?
