There would be at least two results of the \start/\stop-codeblock: first, the code would be pretty printed as you sugggested in the resulting program documentation; second, the code would be written to an external source file foo.c that could then be compiled with, for example, gcc.

Some other features of literate programming include replacement, where in one code block you reference another that should be cut-and-pasted at the point of reference in the resulting source file, and cross-references between code blocks, where in the typeset program documentation each code block is typeset with references to the other code blocks that use it.

Right now, we've got a prototype implementation that properly writes the source files with replacements. In MkIV, right now, the cross-referencing method is not working. We're eagerly (and patiently) waiting for the new MkIV reference method that allows arbitrary userdata, for example, for including a sequence number for code blocks typeset on the same page of the program documentation.

Thanks for your suggestion,

Kevin

Im not exactly sure what you're trying to achieve, but perhaps you could do
this using a prettyprinter? A pretty printer gets passed each line in the
\startfoo \stopfoo block and can change the line in any way it wants
(including removing it). IIRC there is some minimal general preprocessing
done, something with whitespace I think.

Perhaps you could say a bit about what the above should output?
