Emacs

There are a few decent modes for editing noweb.

noweb-mode.el:

This is distributed is very useful, but on slower machines, the parsing and especially highlighting of a large document can be too slow. (Turning off syntax highlighting works acceptably).

It works reasonably well with AUCTeX, however, the one should probably add commands so that C-c C-c compiles the files properly (I use a makefile: see below). REFTeX fails to identify labels, however, which is a bit of a pain.

noweb-outline.el

This is availible from

While very rudimentary, it is quite useful for getting an overview of your code.

snoweb.el

This is a very good idea for a mode that allows you to view your code as noweb-outline.el does, but also allows you to make changes in the code. It can be confused though, and only works with X-Emacs (making use of extents). It is availible at

Ideally, one would like a mode that works like snoweb, and allows you to run a debugger looking at both versions, etc.
