# LinuxCNC WASM SDK

This SDK exposes browser/Node JavaScript wrappers for standalone WASM modules
built from vendored LinuxCNC source.

## Boundary

The SDK is a host-boundary layer only. It may:

- load generated Emscripten modules;
- allocate and free C strings;
- write text files into the Emscripten filesystem;
- call exported C ABI functions;
- return LinuxCNC-produced text output to JavaScript callers.

The SDK must not implement G-code interpretation, canonical motion behavior,
tool semantics, parameter semantics, kinematics, or planner behavior. Those
behaviors must continue to come from vendored LinuxCNC source through the C ABI.

## Entrypoints

Use `src/index.js` for stable imports:

```js
import {
  createLinuxCncIniSdk,
  createLinuxCncInterpSdk,
} from "./src/index.js";
```

`createLinuxCncIniSdk()` wraps the INI parser module built from vendored
LinuxCNC `inifile.cc`.

`createLinuxCncInterpSdk()` wraps the interpreter-core module built from
vendored LinuxCNC RS274NGC sources and exposes:

- `runProgram(programText)`
- `runProgramWithIni(programText, iniPath)`
- `runFile(path)`
- `runFileWithIni(path, iniPath)`
- `restoreParameters(path)`
- `saveParameters(path, values)`
- `writeTextFile(path, text)`
- `readTextFile(path)`
