`ptwm.ext_tooling.build`

ptwm ext build — detect language, run the right toolchain, place the .wasm.

pymodule

module ptwm.ext_tooling.build

ptwm ext build — detect language, run the right toolchain, place the .wasm.

pyfunction

def build_extension(cwd: Path, release: bool = True, flavor: str = 'wasm') -> Path

Build the extension in *cwd* and return the path to the produced binary.

Name	Type	Description
cwd	Path	Root directory of the extension project (must contain ``manifest.toml``).
release = True	bool	When ``True`` (default), build with optimizations enabled.
flavor = 'wasm'	str	``"wasm"`` (default) builds a `wasm32-wasip1` module. ``"native"`` builds a plain cdylib (`.so` / `.dylib`) instead — rust-only.

Returns

Path — Path to the built binary, placed next to ``manifest.toml``.

Raises

BuildError — When language detection or the underlying toolchain invocation fails, or when ``flavor="native"`` is requested for a language that only supports wasm.

pyclass

class BuildError(RuntimeError):

Raised when an `ext build` invocation fails.

pyfunction

def detect_language(cwd: Path) -> str

Detect the build language of an extension project.

Name	Type	Description
cwd	Path	Root directory of the extension project.

Returns

str — One of ``"rust"``, ``"c"``, ``"zig"``, or ``"assemblyscript"``.

Raises
