# The global default profile is now "dev" (-O0 -g, mainstream convention);
# mcpp itself is a shipped tool, so opt its plain `mcpp build` (and release.yml's
# self-host build) back into the optimized profile. Without this the released
# binary would be -O0. A `--profile`/`--dev`/`--release` flag still overrides.

# Split the module edge: importers start when the BMI is published rather than
# when the compiler exits. See docs/05-mcpp-toml.md.
# ON HERE, `auto` (= off) EVERYWHERE ELSE. The key stays opt-in until it has been
# through CI on every platform, and nothing was exercising it, so it could never
# accumulate the evidence needed to change that. mcpp's own build is where that
# evidence is cheapest: whatever this schedule produces has to pass 83 unit tests
# and the full e2e suite, on Linux (detach-codegen, gcc) and on macOS and Windows
# (two-phase, clang) — three platforms, every PR.
# ⚠️ THAT SAFETY NET IS NOT DECORATION — it has already caught one defect. The
# windows-host cross build to x86_64-linux-musl failed on the BMI edge with
#     failed: gcm.cache/mcpp.libs.json.gcm
#     modules/libs/src/json.cppm:3: fatal error: json.hpp: No such file or
#     directory     (the unit was src/libs/json.cppm when this was diagnosed)
# because `cmd.exe /c` does not use CreateProcess argument quoting, so the
# compiler ran with `-I` missing. Fixed in detach_codegen.cppm; see #425.
# Revert is this one line if anything here is ever unexplained.

# Eat our own dog food: mcpp uses mcpplibs.cmdline for argument parsing.
# TOML-native namespaced form: `mcpplibs.cmdline` is the dotted subtable
# `[dependencies.mcpplibs] cmdline = "0.0.1"` ⇒ identity (mcpplibs, cmdline).
# The bootstrap mcpp used by the self-host build (xlings install mcpp, well
# past 0.0.6) understands this, so the legacy quoted form is no longer needed.

# `modules/` holds what gets linked into this binary; `src/` is what has not
# been separated yet, and shrinking it is the direction. Each entry is an
# independent package with its own manifest, so the thing that used to be a
# directory convention is now a boundary the build enforces: a module under
# `modules/` cannot quietly reach back into the engine, because a package
# cannot depend on its consumer.
# A dependency KEY must match the package's identity, and these carry the
# `mcpp` namespace rather than squatting bare `json` / `toml` — dependency
# names resolve in one flat space, so `json = { path = … }` would take a name
# the registry may one day want.
# `[workspace] members` below is what makes `-p` and `mcpp test` address them;
# it is NOT what makes them importable. That is these path dependencies, and
# needing both is easy to get wrong because either one alone looks sufficient.
