Christopher Van Wyk's IDEAL picture language redone in Python: or anyway, some subset thereof, as far as I get, for the sake of understanding it better. This currently doesn't do:
- arcs
- re, im, conj functions
- boundaries and set operations
What it does do:
- solve so-called 'slightly nonlinear' constraints
- default constraints (like
a ~ b) - other built-in functions
- lines, splines, circles
- pens (for a constant number of segments)
To run it: python unreal.py sourcefile1 sourcefile2 ... >out.svg
This uses Parson for parsing.
The full language is explained in the IDEAL User's Manual.
Other interpreters I know of (and so far have only glanced at):
