knot VS fw-utf8

Literate programming seems to becoming popular in the R community due to KnitR and Rmarkdown. This seems to have sparked a few similar-working tools with possibly broader scope and adoption. In my bookmarks I find:

- knot [1]: tangles source code from a text file formatted using plain markdown syntax, can use any markdown converter for weaving into a printable document

- snarl [2]: extends markdown code blocks with syntax used for tangling, its "weave" steps just removes the additional syntax and outputs plain markdown

- pylit [3] [4]: a bidirectional converter: code to formatted text and back. Uses reST for formatting, and preserves line numbers which is useful when debugging. Not an LP tool strictly, as it doesn't define/rearrange code blocks so you have to write your script in the order the compiler wants it, not in the order that would make the best exposition.

Both seem to preserve relative indentation of chunks, so would be useful for Python too.

I'm a fan of https://github.com/mqsoh/knot/

I found Mr. Ross' funnelweb utility to have the best syntax. Unique and easy to read.

Unfortunately the only known implementation was last updated over two decades ago, and is written in pretty hard to understand C.

I asked for permission and started a repository here: https://github.com/loa-in-/fw-utf8

I currently have it unmodified there, except for disabled check for ASCII range. (this modification is included in initial commit, sorry, my bad). Otherwise code is the same.
