I have moved from using noweb to a pure Common Lisp version of literate programming. (The source is also at: http://literatesoftware.com/tangle.lisp )

The noweb program uses two functions, weave -- takes a file and extracts latex tangle - takes a file and extracts running code

The noweb syntax is: <<thechunk>>= your source code @

where your code is defined in the block delimited by the <<...>>= and the @ symbol. To use the delimited chunk somewhere you write the name of the chunk as: <<thechunk>>

It would be better to use a valid latex environment. That would mean that there is no need for a "weave" function since the original file is valid latex.

\begin{chunk}{thechunk} your code here \end{chunk}

\getchunk{thechunk}

All that would be left is to make Common Lisp understand the latex environment syntax which is trivial to do. So I wrote a tangle.lisp program. It accepts and processes both the old noweb syntax and the new latex syntax.

The idea is simple. Read the file, hash the chunks, and expand them when a getchunk is found.

The code is attached.
