# LinuxCNC tooldata source map
|
|
|
|
This map records the source basis and boundaries for LinuxCNC tooldata coverage
|
|
in native, source-link, switchkins, and WASM-safe build paths. It is a
|
|
source-link/shim guard only; it must not add CNC behavior and must not expand the temporary smoke parser.
|
|
|
|
## LinuxCNC Source Basis
|
|
|
|
- `src/emc/tooldata/Submakefile` selects `tooldata_mmap.cc` or
|
|
`tooldata_nml.cc`, and always includes `tooldata_common.cc`,
|
|
`tooldata_db.cc`, and `tool_watch.cc`.
|
|
- `src/emc/tooldata/tooldata_common.cc` provides tool table parsing,
|
|
formatting, load/save, and database-mode entry points.
|
|
- `src/emc/tooldata/tooldata_mmap.cc` provides native mmap tool table storage.
|
|
- `src/emc/tooldata/tooldata_nml.cc` provides the NML tool table registration
|
|
backend selected by `TOOL_NML_FLAG`.
|
|
- `src/emc/tooldata/tooldata_db.cc` provides external database entry points.
|
|
- `src/emc/tooldata/tool_mmap_read.cc` and `src/emc/tooldata/tool_watch.cc` are
|
|
utility sources from the same LinuxCNC tooldata build metadata.
|
|
- `src/emc/tooldata/tooldata.hh` declares the tooldata API used by RS274 and
|
|
WASM-safe shims.
|
|
|
|
## Manifest And Shim Coverage
|
|
|
|
| Coverage | Boundary |
|
|
| --- | --- |
|
|
| `linuxcnc-rs274-source-files.txt` | Tracks the full LinuxCNC `src/emc/tooldata` source directory and `tooldata.hh`. |
|
|
| `linuxcnc-rs274-wasm-source-files.txt` | Links `tooldata_common.cc`, blocks native `tooldata_mmap.cc`, and records runtime shim source bases for `tooldata_db.cc` and `tooldata_nml.cc`. |
|
|
| `linuxcnc-kinematics-source-files.txt` | Tracks 10 LinuxCNC `TOOL_TABLE` files referenced by covered M428/M429/M430 INI sources as `tooldata` source coverage only. |
|
|
| `core/wasm_shims/tooldata/tooldata_mmap_backend.cc` | Adapts LinuxCNC `tooldata_mmap.cc` exports to WASM-safe in-memory storage. |
|
|
| `core/wasm_shims/tooldata/tooldata_runtime_stubs.cc` | Adapts LinuxCNC `tooldata_nml.cc` and `tooldata_db.cc` runtime entry points without native services. |
|
|
| `test-linuxcnc-wasm-tooldata-link.sh` | Links the wasm-safe tooldata shim against LinuxCNC tooldata runtime expectations. |
|
|
| `test-linuxcnc-wasm-tooldata-common-link.sh` | Links LinuxCNC `tooldata_common.cc` through the wasm-safe standalone probe. |
|
|
| `test-linuxcnc-wasm-tooldata-mmap-symbols.sh` | Compares wasm mmap backend exports with LinuxCNC `tooldata_mmap.cc`. |
|
|
| `test-linuxcnc-wasm-tooldata-runtime-symbols.sh` | Compares runtime stub exports with LinuxCNC `tooldata_db.cc` and `tooldata_nml.cc`. |
|
|
|
|
## Boundaries
|
|
|
|
- Tool table files referenced by switchkins INI files are source coverage only;
|
|
they must not become browser API fields or generated switchkins aliases.
|
|
- WASM-safe tooldata shims must preserve the LinuxCNC export surface checked by
|
|
symbol probes.
|
|
- Native and source-link paths must keep the full LinuxCNC `src/emc/tooldata`
|
|
source directory tracked in the native RS274 manifest.
|
|
- `build-wasm.sh` must run tooldata link and symbol probes before copying
|
|
browser artifacts.
|
|
|
|
## Checks
|
|
|
|
Run:
|
|
|
|
```bash
|
|
./check-linuxcnc-tooldata-source-map.sh
|
|
./test-native.sh
|
|
./test-linuxcnc-source-link.sh
|
|
```
|
|
|
|
`check-linuxcnc-tooldata-source-map.sh` keeps this document, LinuxCNC tooldata
|
|
source anchors, manifest coverage, WASM shim/probe boundaries, and switchkins
|
|
TOOL_TABLE source-only policy synchronized.
