Alex Bethel 099b9e23d6 Make base-55 encoding & decoding match 
Changed "U"'s encoding to -210, so now when the README claims "U =
-210", it's actually accurate :)

Alex Bethel 585bf2e19f Use single-letter identifiers as base-55 digits 2021-05-29 10:45:39 -05:00
Alex Bethel c906366e3f Improve name & documentation accuracy 
Renamed ControlFlow -> HaltStatus because that's what the enum really
is -- a status on why something halted. Also reviewed `interpret.rs`'s
documentation and fixed a few things that were out of date.

Alexander Bethel ec81ead3ea Implement break and hopback statements 2021-05-25 21:22:38 -05:00
Alexander Bethel 669f379700 Better abstractions, implement scoping rules 2021-05-25 13:26:01 -05:00
Alexander Bethel 109c77eeb2 Implement more statements 
Added variable declaration, `if` statements, `loop` statements,
variable assignment, and variable banning to go along with
printing (which was already implemented). We still need function
declarations, brainfuck declarations, function calls, and the control
flow operators "break" and "hopback".

Able c27837a807 Slightly more curse 2021-05-24 01:18:36 -05:00
Alexander Bethel b625a71711 Allow abool -> bool coercion 
The expression `sometimes & true` now evaluates to `true` 50% of the
time and false 50% of the time, rather than throwing a type error
because `sometimes` is not a bool.

Alexander Bethel ea211fc3b0 Make ablescript -f run interpreter 
`ablescript -f foo.able` will now both parse and interpret `foo.able`,
rather than just parsing it.

Alexander Bethel eccc00ff81 Implement basic interpreter
