Regarding make, Noweb gets this right. When you edit the web source, the tangle step only writes new modification times to output files that actually changed.

The answer to "where" is <news:comp.programming.literate> and <https://www.reddit.com/r/LitProg/>.

I take a minimalist approach. Any project goes in a single .nw file, formatted for Noweb, edited using Vim. I use a source highlighter that recognizes multiple languages in a single buffer. Noweb generates all my objects, including program text, makefiles, tests, and all documentation. Building the project is just "noweb *nw" followed by "make".

I use Noweb <https://www.cs.tufts.edu/~nr/noweb/>, which is, I believe, very much like nuweb. It is also LaTeX-centric, and also allows code sections to be written in any language. Within code sections, instead of depending on Noweb for code formatting, I use a syntax-aware editor. I configure Vim to recognize the language within each code section. This means that, in Vim, I get formatting and syntax highlighting.

Vim is also able to export syntax highlighted code as HTML markup. Because Noweb is modular and supports plugin filter stages, it might be possible to write a Noweb filter stage that calls Vim, translates the markup to LaTeX, and adds syntax highlighting to the document. This is something I haven't tried.
