Staapl glues Scheme to Forth
Tom Schouten
Announcing the recent release of Staapl, a library for metaprogramming
microcontrollers.
It is centered around the concept of an ``unrolled'' Forth language
tower, impedance-matched to PLT Scheme's declarative module system,
and uses a stack-based pattern language to implement primitives for
code generation, partial evaluation of the pure functional target
language subset and parameterized metaprogramming.
The representation language is a thin layer on top of Scheme
implementing a concatenative language with threaded state which can be
used independently of Staapl.
Current implementation contains a Forth syntax frontend to the
concatenative macro language, a backend code generator for Microchip's
PIC18 architecture, a tethered interaction system, and a test
application implementing a sound synthesizer on a PIC18F1220.
