# One job, three outcomes:

# pull request -> build the Flatpak and run the suite inside it
|

# push master -> also publish the result as the `beta` branch of the
|
||||
# Catcrafts repo and refresh the rolling `latest` release
|

# tag X.Y.Z -> publish as `stable` and create release X.Y.Z

# flatpak-builder state (ccache and the LLVM module, so only crafter-build
|

# itself rebuilds on a normal run) and the published repo's web root.

## Dev environment
|
||||
|

The shipped artifact is the Flatpak (see "CI and publishing"); the loop below is the native development loop.
|
||||
|
||||
Prerequisites on Linux: `clang` (with `libclang`, which the AST lint rules load at runtime), `lld`, `libc++` with its std module source (`share/libc++/v1/std.cppm`), `cmake`, `git`. `crafter-build --version` prints which compiler was resolved; `CRAFTER_BUILD_LLVM_DIR` points it at another LLVM prefix, and `build.sh` honours the same variable. Network access to `forgejo.catcrafts.net` and `github.com` is needed: loading `project.cpp` fetches Crafter.Math, Crafter.Asset and Crafter.LintRules into `~/.cache/crafter.build/external/`, and the bootstrap clones glslang. Those sources are unpinned, so every invocation runs `git pull` on them.

|

|
||||
1. **Configuration is C++.** No JSON, YAML, TOML or DSL for project, runner or lint configuration. Lint rules are C++ callbacks; there is no clang-format or clang-tidy integration and no separate "format rule" type. A rule that calls `ctx.SetContent` is a transform, and that is the whole mechanism.
|
||||
2. **Per-project artifacts go in `<project>/build` and `<project>/bin`. Only cross-project things go in `~/.cache/crafter.build/`:** the std PCM and Crafter.Build PCMs per target and march, and external clones keyed by their spec hash.
|
||||
3. **Sources ship, PCMs build locally.** Packages install `*.cppm` under `share/crafter-build/`. Nothing target-baked ships except the executable itself, and that defaults to a portable `-march` in `PKGBUILD` and CI.
|
||||
3. **Sources ship, PCMs build locally.** The Flatpak installs `*.cppm` under `/app/share/crafter-build/`. Nothing target-baked ships except the executable and the toolchain beside it, and the executable is built for a portable `-march`.
|
||||
4. **crafter-build is a monolithic executable with `--export-dynamic`.** `project.so` resolves `Crafter::` symbols from the running binary at dlopen time. There is no Windows host; `x86_64-w64-mingw32` is a cross-compile target for user projects only.
|
||||
5. **Convention over configuration.** Lead with the zero-config path. Env var, then CLI flag, then full `project.cpp` are the escalation, not the entry point.
|
||||
6. **One skip mechanism** (runner probe plus exit 77) and **one `TestRunner` shape** (template fields with `{bin}`, `{bundle}` and similar placeholders; `Cmd(...)` covers any wrapper). Do not add a special-case runner class or a hardcoded "skip on this OS" branch.

|

|
||||
## CI and publishing
|
||||
|
||||
`.forgejo/workflows/ci.yaml` runs on the `flatpak` runner label: the privileged forgejo-runner on the Hetzner box (bubblewrap inside the job container needs it). Its `config.yml` allows three volumes, which the workflow mounts: `crafter-flatpak-system` (the Sdk install at `/var/lib/flatpak`), `crafter-flatpak-builder` (flatpak-builder state and ccache, so the LLVM and WASI modules are rebuilt only when their sources change) and `/var/www/flatpak`, the web root Caddy serves as `https://flatpak.catcrafts.net/`. Secrets: `FLATPAK_GPG_PRIVATE_KEY` (armored, no passphrase) and `FLATPAK_GPG_KEY_ID`. The live repo at `/var/www/flatpak/repo` is canonical; builds are promoted into it with `flatpak build-commit-from`, never built into it.
|
||||
|
||||
To release: add a `<release>` to `packaging/flatpak/net.catcrafts.CrafterBuild.metainfo.xml` (its description becomes the release notes), merge, and push the tag `X.Y.Z`. CI refuses a tag that does not match the newest entry. Local builds: `flatpak-builder --user --force-clean --ccache --repo=repo build-dir packaging/flatpak/net.catcrafts.CrafterBuild.yaml`, then `flatpak-builder --run build-dir <manifest> crafter-build --version`.
|
||||
|
||||
## Gotchas
|
||||
|
||||
- A `#pragma crafter dependency` target is rebuilt on every load on purpose: clang crashes rather than erroring when it imports a BMI whose own imported PCM was rebuilt underneath it, and the depfile check is what catches a regenerated host cache. Do not optimise the rebuild away.

A C++26 modules build system. Project descriptions are written in C++ with no JSON, no Lua, no embedded DSL. You write a `project.cpp` that constructs a `Configuration` and returns it; Crafter Build compiles, loads, and executes it.
|
||||
|
||||
## Quick start (Linux)
|
||||
## Install
|
||||
|
||||
Bootstrap requires `clang`, `cmake`, `git`, `lld`, and `libc++`.
|
||||
crafter-build ships as a Flatpak that carries its own clang, lld, libc++ and WASI sysroot, so every machine builds with the same compiler:
|
||||
|
||||
```bash
|
||||
flatpak remote-add --if-not-exists catcrafts https://flatpak.catcrafts.net/catcrafts.flatpakrepo
|
||||
flatpak install catcrafts net.catcrafts.CrafterBuild
|
||||
alias crafter-build='flatpak run net.catcrafts.CrafterBuild'
|
||||
```
|
||||
|
||||
Pre-release builds of `master` are the `beta` branch (`flatpak install catcrafts net.catcrafts.CrafterBuild//beta`), and every release also attaches a single-file bundle on the Forgejo releases page (`flatpak install --user crafter-build-<version>.flatpak`). The sandbox sees the whole host filesystem, so projects can live anywhere. Binaries built for the host link the bundled `libc++.so.1` through an rpath into the Flatpak: they run inside it (`-r`, the test runner), and are not meant to be copied out onto the host.
|
||||
|
||||
## Building from source (Linux)
|
||||
|
||||
The development loop is native. It needs `clang`, `cmake`, `git`, `lld` and `libc++` with its std module source:
|
||||
|
||||
```bash
|
||||
./build.sh # produces bin/crafter-build
|
||||
|
|
@ -13,13 +25,7 @@ Bootstrap requires `clang`, `cmake`, `git`, `lld`, and `libc++`.
|
|||
|
||||
The compiler is resolved once per run: `CRAFTER_BUILD_LLVM_DIR` if set, else a `clang++` installed beside crafter-build (`<prefix>/bin`), else PATH. `crafter-build --version` prints the version and the compiler in use; `crafter-build --help` lists the other overrides (`CRAFTER_BUILD_LIBCXX_DIR`, `CRAFTER_BUILD_LIBCLANG`, `CRAFTER_BUILD_WASI_SYSROOT`, `CRAFTER_MINGW_DIR`). A `Configuration` targets the host triple unless `cfg.target` says otherwise.
|
||||
|
||||
The bootstrap targets the host toolchain's own triple (`clang++ -print-target-triple`): `x86_64-pc-linux-gnu` on glibc distros, `x86_64-alpine-linux-musl` on Alpine/postmarketOS (`apk add clang clang-dev lld libc++-dev llvm-libunwind-dev llvm-runtimes llvm llvm-dev cmake build-base python3 git`). Override with `CRAFTER_BUILD_TARGET=`. CI ships both: `crafter-build-linux-x86_64-v{2,3,4}.tar.gz` (glibc) and `crafter-build-linux-x86_64-musl-v2.tar.gz` (musl, needs `libc++` at runtime — the launcher dlopens `project.so`, so it cannot be static).
|
||||
|
||||
To build the system as a distro package on Arch:
|
||||
|
||||
```bash
|
||||
makepkg -si # uses CRAFTER_BUILD_MARCH=x86-64-v3 by default for portability
|
||||
```
|
||||
The bootstrap targets the toolchain's own triple (`clang++ -print-target-triple`); override with `CRAFTER_BUILD_TARGET=`. The Flatpak is built from `packaging/flatpak/net.catcrafts.CrafterBuild.yaml`, which runs this same bootstrap, the self-host build and the test suite inside the sandbox against the bundled toolchain (`CRAFTER_BUILD_LLVM_DIR=/app`).

|
||||
A build system for C++26 modules. Project descriptions are C++: a
|
||||
project.cpp constructs a Configuration and returns it, and crafter-build
|
||||
compiles, loads and executes it. The Flatpak carries its own LLVM, so
|
||||
every machine builds with the same clang, lld, libc++ and WASI sysroot.
