Some checks failed
CI / build-test-release (pull_request) Failing after 44s
WASI / wasm32 target support
- Auto-detect /usr/share/wasi-sysroot on Linux when target starts_with("wasm32")
- Skip -march/-mtune for wasm (clang rejects them)
- Apply -fno-exceptions -fno-c++-static-destructors -mllvm -wasm-enable-sjlj
-D_WASI_EMULATED_SIGNAL to wasm builds (compile + std PCM, kept in sync)
- .wasm output extension in expectedOutputFor and link command
- EnableWasiBrowserRuntime(cfg): opt-in helper that drops index.html +
runtime.js next to the .wasm; runtime.js reads window.CRAFTER_WASM_URL
set in the templated index.html so a single shim handles any output name
-r run flag in the CLI: build then exec the artifact (host targets only;
rejects libraries; auto .exe/.wasm extension handling)
CI pipeline (.forgejo/workflows/ci.yaml)
- Triggers: PR/push to master + manual dispatch
- Single arch-latest container job: install deps, bootstrap, self-rebuild,
run tests, cross-compile mingw, package both archives, upload artifacts
- Rolling 'latest' release published only on push/dispatch to master
mingw cross-compile from Linux now works end-to-end:
- ExternalDependency cache key includes target so per-target glslang builds
don't collide; CMAKE_BUILD_TYPE=Release pinned (otherwise glslang appends
'd' to lib names and breaks linking); cross-compile cmake flags
(CMAKE_SYSTEM_NAME=Windows, CMAKE_*_COMPILER_TARGET=...)
- project.cpp accepts --target=<triple>; Linux-only -Wl,--export-dynamic
and -ldl are gated; mingw glslang skips the standalone exe (its libgcc_eh
link pulls pthread which mingw doesn't link by default)
- mingw compile uses -femulated-tls so std::__once_callable etc reference
the same emutls symbols libstdc++ provides
- mingw link auto-adds -lstdc++exp -lpthread
GetCrafterBuildHome() exposed from the Platform module; LoadProject (Linux
+ Windows) now both use it instead of duplicating the resolution.
Examples reorg: hello-world, library, with-module, wasi, tests — each with
its own README. Tests reorg: per-test directory with inner/ fixture, no
shared tests/fixtures/ tree. New Wasi test verifies .wasm magic bytes.

# tests
|
|
|
|
Two ways to write tests, in one project.
|
|
|
|
```sh
|
|
cd examples/tests
|
|
crafter-build test
|
|
```
|
|
|
|
Layout:
|
|
|
|
```
|
|
mylib/MyMath.cppm # the library being tested
|
|
project.cpp # declares the library
|
|
|
|
tests/Smoke/main.cpp # zero-config test (no project.cpp)
|
|
tests/UnitMyMath/main.cpp # test that links MyMath and exercises it
|
|
tests/UnitMyMath/project.cpp # required for tests with deps
|
|
```
|
|
|
|
## Auto-discovery
|
|
|
|
Each `tests/<Name>/` directory becomes a test. Three layers, escalate only as needed:
|
|
|
|
1. **`tests/<Name>/main.cpp`** with no `project.cpp` — discovery synthesizes a Configuration. Top-level `*.cpp` files become implementations, `interfaces/*.cppm` become module interfaces. `Smoke` is this case.
|
|
2. **`tests/<Name>/project.cpp`** — full control. Use this when you need defines, dependencies, or non-default targets. `UnitMyMath` is this case (it depends on `MyMath`).
|
|
3. Folders starting with `_` or `.` are skipped (e.g. `tests/_shared/` for cross-test helpers).
|
|
|
|
## Test conventions
|
|
|
|
- Exit code `0` = pass, anything nonzero = fail, **`77` = skipped** (autoconf convention). Use `std::exit(77)` for runtime skips like "tool not on PATH".
|
|
- Each test runs in its own subprocess; a segfault doesn't take down the runner.
|
|
- Default timeout is 60 s (`crafter-build test --timeout=N` overrides).
|
|
- Filter by name: `crafter-build test 'Unit*'`. List without running: `crafter-build test --list`.
|
|
|
|
## Linking the parent project
|
|
|
|
`UnitMyMath/project.cpp` shows how a test links the project's own library:
|
|
|
|
```cpp
|
|
cfg.dependencies = { ParentLib("MyMath") };
|
|
```
|
|
|
|
`ParentLib("name")` looks up a `Configuration*` in the parent project (the root project's own config + its dependency graph) by `Configuration::name`. The fixture's project.cpp can omit `cfg.path`, `cfg.name`, etc. — the discovery loop fills folder-derived defaults.
|
|
|
|
## Cross-target test runs
|
|
|
|
Tests parse `--target=...` from the project args you pass on the command line:
|
|
|
|
```sh
|
|
crafter-build test --target=x86_64-w64-mingw32 --runner=cmd:wine
|
|
```
|
|
|
|
`--runner=<spec>` overrides the per-target runner for this invocation. Useful specs: `local`, `cmd:<command>` (prefix-exec, e.g. `cmd:wine`, `cmd:qemu-aarch64`), `ssh:<host>[:<remoteDir>]`, `sshwin:<host>[:<remoteDir>]`. Or persist via env var: `CRAFTER_BUILD_RUNNER_<normalized_target>=<spec>`.
