# writeonce — task runner. `just --list` shows all recipes.

# woc compiler front (compiler/): build the executable
woc-build:
    dune build --root compiler

# woc gate: unit tests (test_diag) + golden suite (runner, WOC_BLESS=1 to update)
woc-test:
    dune runtest --root compiler

# wovm (runtime/): build the plain, optimized binary — the release build,
# no sanitizer (wovm-test is the ASan-clean gate; `make -C runtime wovm-asan`
# builds a separate sanitized binary for the corpus, see oop-accept)
wovm-build:
    make -C runtime wovm

# wovm gate: unit suites (both dispatch flavors: computed-goto + ISO switch
# under -DWO_ISO_C, so neither rots) + CLI smoke, all ASan+UBSan
wovm-test:
    make -C runtime test
    make -C runtime test-iso

# dist: package the toolchain as an installable, Go-style tarball —
# writeonce-<ver>-linux-amd64.tar.gz whose `writeonce/bin/` holds woc + wovm.
# The version is single-sourced from ./VERSION and asserted against both
# binaries (drift guard). See scripts/mkdist.sh.
dist:
    ./scripts/mkdist.sh

# deps-accept: iteration 15's gate — wo.toml [deps] + git fetch + wo.lock,
# proven against local file:// remotes built at run time (network-free):
# cold fetch, offline rebuild, lock-beats-moved-tag, --update-deps, drift/
# transitive/collision diagnostics, dep-main-never-entry, manifest shape.
deps-accept:
    ./scripts/deps-accept.sh

# install-accept: extract the dist tarball to a temp prefix, PATH it, and prove
# `woc version` + a from-scratch project build+run (self-located wovm) + the
# wo-constraint refusal all work — the "tarball install actually works" gate.
install-accept:
    ./scripts/install-accept.sh

# the sample workload's own recipes live beside it (build from wo.toml,
# the acceptance test, the soak): `just log-watcher` runs the acceptance,
# `just log-watcher::build` / `::soak 60` the rest — see the module's
# justfile for what each does. This is the test the whole track exists to
# pass; the corpus below gates the individual behaviors underneath it.
mod log-watcher "docs/examples/log-watcher"

# the database track's acceptance workload (iteration 9/9b): @table storage,
# ref/backlink relations + FK restrict, and the compiler-checked query surface
# (scan/where/select/order/take, update, delete). `just employee` runs it.
