an ML/Haskell/Rust-inspired interpreted functional programming language

This is a C reimplementation of an original Rust project.

See html.ham for a syntax example. A more complete example or specification might come later at some point.

├─ lib           core library source code, could be compiled into a shared library in the future
├─ src           source code for the CLI frontend, for now it's just a placeholder for testing
├─ test          files with the `test_` prefix define test cases
│  ├─ lib        testing macros & utilities
│  ├─ runner     test entry point and auto-generated index
│  └─ snapshots  saved snapshots for snapshot testing
├─ build_test.c  a small build tool for indexing tests
├─ bench         files with the `bench_` prefix define benchmarks
└─ vendor        vendored third-party libraries

• C compiler, the project is configured for clang tooling
• GNU Make

Make and run the release build:

make # or `make release`
bin/hammer

Make and run the debug build:

make debug
bin/hammer-debug

Make and run tests:

make test
# or run a specific test
make test TEST=<test-name>
# sanitizers are disabled in tests by default to avoid cluttering output
make test TEST_ASAN=1

Review changed snapshots (interactive):

make test HAMMER_SNAPSHOT_REVIEW=1

Run benchmarks

make bench
# or run a specific benchmark
make bench BENCH=<bench-name>

The project is configured to work with clangd and clang-format. Run make format to auto-format the entire project.

Other code style guidelines which cannot be enforced via tooling are described here.
