Work-in-progress interpreter loosely based on clox, from [Crafting Interpreters] (https://craftinginterpreters.com/). Unlike clox, this interpreter is implemented in Rust.

Commit messages in this repository start with an intention and risk level, following Arlo's Commit Notation.

• To get code coverage using grcov:

  • cargo install grcov cargo-watch
  • rustup component add llvm-tools-preview
  • mkdir -p target/debug/coverage
  • In your shell config file, add:
    • export RUSTFLAGS="-Zinstrument-coverage"
    • LLVM_PROFILE_FILE="target/debug/coverage/llvm-profile-%p-%m.profraw"
  • To run tests and update the code coverage when a file is saved, use cargo watch -x test -s ./watch.sh
    • To view the coverage in VSCode, use the Coverage Gutters plugin.

• To analyze compile time:

  • run cargo +nightly build -Z timings --release to generate cargo-target.html
  • open it in your browser: open cargo-target.html from this directory.
