Hello,
I'm trying to write some filters from Pygments, and to record what I'm
doing and make my life simpler, I'm doing it in an orgmode buffer. In
that buffer, I have the code I want to highlight in a source block, and
the python code for the Pygments extension in another block. I'm trying
to find out how to pass the escaped code from the source to highlight to
the python buffer.
I tried using noweb, but the expansion is verbatim and python complains
about the line breaks. So I'm wondering if there is a way to:
- pass a source block as an escaped string to another source block, or
- save a source block to a temporary file, and pass the file name to
a second source block.
Thanks,
Alan

defun a function that formats your src block, then use it in a header
:var x=(foo "src-block-name")
or maybe wrap (foo ...) in a `format' call or `prin1-to-string' call.
An example is below.
===
Another alternative is to use this idiom (see 14.10 Noweb reference syntax)
<<code-block-name(optional arguments)>>
where the code-block-name specifies a formatter (in elisp, say) and
the optional argument is the name of the code block you want to format.
HTH,
Chuck

Thanks a lot, it works great. I'm now having utf-8, orgmode, and python
problems that I'll explore in another thread.
