You are right. And it should be easier to add different highlight styles.

Sadly, or maybe luckily, I have to convert a complicated piece of code
to literate programming. Or comment it better... I wrote it 2 months
ago, and now I can't make heads or tails of it. And it has to be done
by yesterday....
But, I think literate programming in TeXmacs with your noweb style
already works really well. Good enough for me to use, and better than
anything else I found.

I think that TeXmacs sessions should also have the weaving property. I
often wanted to export a document with many R sessions in it to an R
document without the text. Now I have to copy/paste through all the
snipplets.

I think another very important property is that TeXmacs should be able
to take a document apart into many different files (as is happening
now with noweb), and also do the reverse - put the pieces back into a
document. Of course for that, one needs to write codes in the files
about where each piece came from. I think it is not hard to implement.
With that, one could debug and edit the code externally, and then
reassemble the program back to the document.


thanks again,
Michael
