At the end of this link: https://savannah.nongnu.org/task/download.php?file_id=21016 you will find a sample of literate programming on texmacs using a new stylesheet, based on the noweb style as used by me with Lyx and Latex.

* <label> in a code chunk generates reference text like" 2d line 3"
* each named chunk automatically generates a label that can be accessed like <chunk-reference|message-printf|1> (to get the first block named chunk-reference).
* line numbers are automatically continued between chunks of the same name

Now I just need to adapt my extraction tool (at new.fangled.org).

Features I intend to add to the texmacs stylesheet are:

* optional in-place expansion if referenced chunks (for illustrative purposes)
   [depends on me getting recursive expansion of document tree to insert new <item> at right point (for line numbering)]
* decoration of expanded referenced chunks using braces or over-braces
* parameterized chunks (use to write algorithms - sort of like poor-mans STL/generics)
* in-place expansion of parameters in parameterized chunks (for illustrative purposes)

To get this to work well I need to know how to read the results of <write|...|...>

I note that langle and rangle come out badly in html (literally langle and rangle) and not at all in text

Comments invited.
