Alex Bethel 2cb915dd24 Prettier error handling 2021-06-04 18:56:26 -05:00
Alex Bethel 98b2fae6f3 Clean up eval_expr some more 
I keep going back and forth on how I want this block to look :P
Anyway, this is *probably* its final-ish form, until the parser gets
re-written.
 2021-06-02 18:41:20 -05:00
Alex Bethel d80f47716d Use impl Value rather than trait BfWriter 
It probably makes more sense to be writing values with
`Value::bf_write` than to go for the complexity of using a trait to
allow `Writer::write_value` (which also looks ambiguous because it's
not immediately clear that a generic name like "write_value" relates
to BF or AbleScript).
 2021-06-02 18:20:30 -05:00
Alex Bethel 2c35691ec4 Add Brainfuck functio interpretation 
BF functios can now be declared and called from AbleScript code.
Function parameters supplied from AbleScript are serialized manually
into byte sequences using the `BfWriter` trait, and are available from
BF code using the input operator, `,`.

At the moment, BF functios simply write output to stdout, and are
therefore incapable of communicating results to the rest of the
program; this might change in the future if we can get something close
to pass-by-reference working.
 2021-06-02 15:29:31 -05:00
Alex Bethel b3866eea9e Fix panic on arithmetic error 
Divide by zero and add, subtract, or multiply with overflow are all
caught now and reported as an ArithmeticError, rather than causing the
interpreter to panic.
 2021-05-30 13:32:29 -05:00
Alex Bethel d13c22a473 More thorough unit tests 2021-05-30 13:32:29 -05:00
Alex Bethel 7bfefd3ba1 Add some unit tests to interpret.rs 
Currently `overflow_should_not_panic` and `variable_persistence` both
fail due to bugs in the interpreter.
 2021-05-30 13:32:29 -05:00
Alex Bethel fcfa83a8a6 Make base-55 encoding & decoding match 
Changed "U"'s encoding to -210, so now when the README claims "U =
-210", it's actually accurate :)
 2021-05-29 14:24:46 -05:00
Alex Bethel 00e80e9740 Use single-letter identifiers as base-55 digits 2021-05-29 10:45:39 -05:00
Alex Bethel 51db37f1fe 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documentation and fixed a few things that were out of date.
 2021-05-25 21:55:02 -05:00
Alexander Bethel 7537b4ac98 Implement break and hopback statements 2021-05-25 21:22:38 -05:00
Alexander Bethel e7560f9364 Better abstractions, implement scoping rules 2021-05-25 13:26:01 -05:00
Alexander Bethel 1c2032ab87 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".
 2021-05-24 10:50:26 -05:00
Able b37c189da9 Slightly more curse 2021-05-24 01:18:36 -05:00
Alexander Bethel e79fc9a005 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.
 2021-05-21 12:25:37 -05:00
Alexander Bethel 464337bd53 Make ablescript -f run interpreter 
`ablescript -f foo.able` will now both parse and interpret `foo.able`,
rather than just parsing it.
 2021-05-20 18:24:18 -05:00
Alexander Bethel e31b8fb00d Implement basic interpreter 
Added code for interpreting parsed AbleScript expressions and
statements, and hooked it up to the REPL.
