A new compiler that can compile natural languages. Support simple arithmetic options based on numbers and floats. A file with natural language will be compiled as assembly code (x86_64 with FPU) and calculate results.

To install rustc, run
sudo apt-get install rustc
To run the code, run
cargo run
To compile a program and emit assembly code to stdout use
snake INPUT_FILE
To compile a program, link it and run the produced binary use
snake --run INPUT_FILE
To run the reference interpreter use
snake --interp INPUT_FILE
To see this usage message run
snake --help
To test the examples in ./examples/, run
cargo test
To add new tests, add new mk_test! and mk_fail_test! in ./tests/examples.rs
