Erin	b9d10fae03	AST revamp ... - Unified terminology of span in error.rs	2021-06-06 23:13:48 +02:00
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	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
