Building an Executable

hyc build compiles Hylang source to a native binary through the C backend.

Compile a single file​

build/hyc build tests/hello_world.hy -o build/hello_world
./build/hello_world

Compile a project​

build/hyc build tests/projects/app/App.hyproj -o build/demo_app
./build/demo_app

Compile the runtime proof project​

build/hyc build samples/managed_collections/ManagedCollections.hyproj -o build/managed_collections
./build/managed_collections

Build a static library​

build/hyc build tests/projects/mathlib/Math.hyproj --target lib -o build/libmathlib.a

Notes​

  • The C backend emits a single C translation unit that is compiled and linked by the host C compiler.
  • Compiled output now uses an in-tree non-moving mark-sweep GC with managed strings and arrays.
  • HYLANG_GC_STRESS=1 forces collection at runtime safe points, and HYLANG_GC_THRESHOLD=<bytes> lowers or raises the compiled-runtime collection threshold.
