Simple picture language

[Ricardo Wurmus <rekado@elephly.net>]

Hi Guilers,

I wrote a simple SVG-based picture language.  To try it:

    wget https://elephly.net/downies/pict.scm

Then start geiser in Emacs and load the module:

    M-x run-guile
    (add-to-load-path (getcwd))
    ,use (pict)

Let’s play!

    (circle 100)
    (colorize (circle 100) "red")

    ,use (srfi srfi-1)
    ,use (srfi srfi-26)
    (apply hc-append (map (cut circle <>) (iota 10 2 4)))

    (apply cc-superimpose (map (cut circle <>) (iota 10 2 4)))

    (apply hc-append (map (cut rotate (rectangle 10 30) <>) (iota 36 0 10)))

    (apply cc-superimpose (map (cut rotate (triangle 100 300) <>) (iota 36 0 10)))

And so on.

There’s also “blur”, but it doesn’t show up right in Geiser; it seems
that Emacs doesn’t render SVG filters.

What do you think?
