sane.mk

Quick model

• Choose the smallest entrypoint: sane.mk, sane.std.mk, sane.extra.mk, or template/sane.tf.mk.
• Extend behavior by appending leaf targets to SANE_* variables such as SANE_DEPS, SANE_CHECK, SANE_TEST, and SANE_SYSTEM.
• Keep top-level verbs declarative; put real work in deps/*, check/*, test/*, system/*, debug/*.

Validation entrypoints

In a sane.mk repo, NEVER invoke linters/formatters/test runners directly (e.g. markdownlint, ruff, yamllint, shellcheck, pytest). Always use:

• make check — lint, format, static analysis, secret scanning
• make test — tests
• make all — build
• make clean — clean generated files

Makefile.lazy resolves tool paths and the repo's config files (e.g. .markdownlint.jsonc, .ruff.toml) are wired into these targets. Direct invocation bypasses that wiring and runs a strict subset of the checks.

Repo rules

• ## comments feed make help.
• Target names use /; keep .PHONY on its own line.
• Make vars use $(VAR); bash vars use $${VAR}.
• Resolve tools with $(call which,NAME,gname name) into ALL_CAPS variables.
• Prefer wrappers like $(MKDIR), $(CP), $(LN), $(RM) and lazy helpers like $(call make-lazy-once,VAR).

Common tasks

• Add a checker:

Use real tab characters in actual recipe lines.

SANE_CHECK += \
  check/foo \

.PHONY: check/foo
check/foo: ## Check foo.
<TAB>$(FOO) --check .

• Add a system dependency:

# Brewfile
brew "shellcheck"

Run make system or make test/system/brewfile.

• Add a generated file or folder:

SANE_DEPS_FILES += config/generated.env
SANE_DEPS_FOLDERS += deps/folders/tmp

config/generated.env:
<TAB>$(TOUCH) $@

Guardrails

• Do not reimplement all, deps, check, build, test, dist, ci, clean, debug, or system unless changing the framework itself.
• Preserve formatting and comment conventions; help output depends on them.
