Rust implementation of Lox.
This implementation is compatible with clox, except for closures, which capture by value instead of by variable.
To try out the language and see all its features, visit the playground!
To see all possible flags, run:
$ cargo run -- --help
The binary supports executing a file and opening a REPL environment.
File
$ cargo run --release --example cli -- file test.lox
fib(30) = 832040
Calculated in 226.47212982177734ms
REPL
$ cargo run --release --example cli -- repl
> var a = 10;
> print a;
10
Running the binary without the --release flag will additionally print the disassembly of the program, as well as disassemble each instruction as the program is running.
$ cargo run --example cli -- repl
> var a = 10;
