SixtyPical
|
|
==========
|
|
|
|
SixtyPical is a very low-level programming language, similar to 6502 assembly,
|
|
with static analysis through abstract interpretation.
|
|
|
|
In practice, this means it catches things like
|
|
|
|
* you forgot to clear carry before adding something to the accumulator
|
|
* a subroutine that you call trashes a register you thought was preserved
|
|
|
|
and suchlike.
|
|
|
|
It is a **work in progress**, currently at the **proof-of-concept** stage.
|
|
|
|
The current released version of SixtyPical is 0.4. The current development
|
|
version of SixtyPical, unreleased as of this writing, is 0.5-PRE.
