This project supports language-independent literate programming. It's a reimplementation of the nuweb project in Python.

So far, the parts implemented (you may like to refer to the nuweb user guide) are:

• files (@o and @O)
  • The flag -t is supported (suppress tab expansion within this file)
• fragments (@d and @D)
• scraps (delimited by @{ @} only)
• user-defined identifiers
• old-style fragment parameters
• indices @f, @m and @u (I've laid @u out a little differently)
• @% (anywhere in the document, not just in scraps)
• @# (put code line at left margin)
• @@ handling (this one was tricky, and I may not have caught all the cases)
• switch -l (use the listings package), aliased --listings
• switch -r (generate hyperlinks), aliased --hyperlinks.

Includes Emacs support in poly-nuweb.el, a minor mode based on https://github.com/polymode/polymode. See its header for installation notes.
