flac.tcl VS cfr

- https://github.com/wader/flac.tcl

In most cases i learned way more then i expected. Even made some friends.

fun fact: fq is kind of the spiritual predecessor of https://github.com/wader/flac.tcl, you can see traces of it in flac_frame.go in fq, was used to prototype some things :)

Thanks! The sibling comment by majewsky is spot on. There is not much parsing going on. Every character is read one by one and the turtle's state is changed. Indeed the "[" and "]" commands are implemented with a stack.

The entire implementation is a single HTML page written in plain HTML + JavaScript. The evaluation of the code happens here: <https://github.com/susam/cfr/blob/0.2.0/cfr.html#L204>.

This is very timely because I completed writing a useless software just a few minutes ago:

CFR Brackets: https://susam.net/cfr.html

It is a very minimal drawing language that supports only 5 commands: C (change colour), F (move forward), R (rotate), [ (begin block), and ] (repeat block). The commands are slightly inspired by the Logo programming language. The minimal nature is inspired by P′′.

No practical usage is intended. I wrote it for fun and I am hoping I will have some more fun with it trying to draw interesting shapes with it while trying to keep the input code as small as possible.
