Currently you can only compile this lib via Clang and cmake.
|

|
||||
## Build output and managed deployment
|
||||
|
||||
From the repository root:
|
||||
|
||||
```powershell
|
||||
cmake --preset clang-debug -S src/Nitload.Native
|
||||
cmake --build cmake_build/clang-debug --target Nitload.Native
|
||||
```
|
||||
|
||||
CMake writes `Nitload.Native.dll` and its linker PDB to `bin/win-x64` on Windows x64
|
||||
(Linux uses `bin/linux-x64/libNitload.Native.so`). Debug and release presets currently
|
||||
share this platform directory; the most recent native build is the deployed version.
|
||||
`NIF_BUILD_OUTPUT_DIR` can override the destination. Managed builds pass their expected
|
||||
RID as `NIF_EXPECTED_RID` so an incompatible native target is rejected before deployment.
|
||||
|
||||
`StgSharpDebug.csproj` enables `BuildNativeBeforeManaged` and `RequireNativeLibrary`.
|
||||
Its build runs the incremental CMake build (`clang-debug` for Debug, `clang-release`
|
||||
otherwise), then deploys the native library to the executable's actual `TargetDir`.
|
||||
Other managed projects copy an existing native artifact without invoking CMake.
|
||||
Managed-output staging never copies deployed native files back over the CMake artifact.
|
||||
|
||||
To use a prebuilt native artifact, pass `-p:BuildNativeBeforeManaged=false`. A matching
|
||||
Clang/Ninja environment and the local GLFW static library are required for native builds.
|
||||
Cross-target builds require a matching toolchain/preset; changing a managed platform alone
|
||||
does not cross-compile the C library.

dotnet run --project test/StgSharpDebug/StgSharpDebug.csproj
|
||||
```
|
||||
|
||||
## NGRA generation preview
|
||||
|
||||
`StgSharpDebug/TestRegexGenerate.cs` contains a standalone debugging routine that calls the
|
||||
existing NGRA emitter without Roslyn attribute binding. Select it from the debug `Main`:
|
||||
|
||||
```powershell
|
||||
dotnet run --project test/StgSharpDebug/StgSharpDebug.csproj -- --regex-preview
|
||||
```
|
||||
|
||||
This branch returns before `World` or native-memory initialization. Without the switch, the
|
||||
existing debug flow is unchanged. You can also call `TestRegexGenerate.Run()` directly from
|
||||
`Main` while debugging; pass a pattern to `Run("abc")` for a single preview.
|
||||
The switch only selects runtime behavior; building the debug project still builds its normal
|
||||
project references, including Graphics and Mathematics, and prepares the native library with
|
||||
CMake. `BuildNativeBeforeManaged` defaults to true; Debug selects `clang-debug`, and other
|
||||
configurations select `clang-release`. `RequireNativeLibrary` reports a missing DLL at build
|
||||
time instead of allowing the default runtime path to fail later.
|
||||
|
||||
For managed-only preview work without a native toolchain or DLL, add
|
||||
`-p:BuildNativeBeforeManaged=false -p:RequireNativeLibrary=false` before `--` in the run command.
|
||||
|
||||
Enter raw regular expressions without C# string delimiters. The routine prints only the emitted
|
||||
code, without status headers or file output. Exceptions propagate directly to the caller/debugger.
|
||||
Use `:exit` or end-of-input to leave the loop. Empty input is an empty regex. For one-shot mode:
|
||||
|
||||
```powershell
|
||||
dotnet run --project test/StgSharpDebug/StgSharpDebug.csproj -- --regex-preview 'a{2,3}'
|
||||
```
|
||||
|
||||
Set breakpoints in `TestRegexGenerate.cs` or any existing `Generate*` method. The output is a
|
||||
method-body fragment; this routine does not compile or execute it.
|
||||
|
||||
New repeatable tests should use a test project and avoid machine-specific paths, external mutable data, and dependencies on previous test execution. Keep one-off investigations in `SingleFile` or the manual debug harness until their expected behavior is stable enough for automation.
