How to Use

Usage: rust_compiler_construction.exe [OPTIONS] [INPUT]

Arguments:
  [INPUT]  Specifies the path to an input .jj file. If None, it means stdin is used for input

Options:
  -o, --output <OUTPUT>  Specifies the path to an output file. If None, it uses the input filename. If that's also None, it defaults to "output"
  -h, --help             Print help
  -V, --version          Print version

Examples

These examples demonstrate how to build and run the compiler using Cargo.

Run with input from stdin:

echo "fn main() { print(42); }" | cargo run && ./output

Run with specified input path, without specifying an output path:

cargo run -- example.jj && ./example

Run with specified input path and specified output path:

cargo run -- input.jj -o output && ./output
