#make

Version 0.2.1 behavior is documented here. The support record separates local verification from published MoonX behavior; moonx examples use registry releases.

cli/make provides a Make subset implemented in MoonBit. Use -f/--file FILE to select a makefile, -C DIR to change its working directory, -n/--just-print for dry runs, -s/--silent to suppress recipe echo, and -B/--always-make to force rebuilding. Target operands and NAME=VALUE command-line assignments are accepted.

include, -include, sinclude, command-line variable assignment, ifeq/ifneq/ifdef/ifndef, pattern/static-pattern dependencies, and automatic variables ($@, $<, $^, $+, $*, $@D, $@F, $<D, $<F) are supported in the implemented slice. -j N schedules independent targets concurrently with at most N recipe chains, and bare -j permits all ready targets. Shared prerequisites execute once. -k continues independent targets after recipe failures, and -W marks targets depending on the named file out of date. The full GNU built-in database, jobserver and secondary expansion remain outside the supported subset. $(shell ...) uses the MoonBit shell, converts embedded newlines to spaces, strips trailing newlines and updates .SHELLSTATUS. -C supplies the recipe and shell-function working directory.

Each external command in a recipe is launched through the public MoonBit process API. The complete Makefile is never forwarded to a host make executable. The remaining language surface is listed in the support record.

Recipes inherit the complete caller environment plus explicitly exported and command-line make variables. export NAME[=VALUE] and unexport NAME control exports; unexported make variables remain local. Bare export/unexport are rejected. Authorization is applied by the caller or host, and locale variables are not rewritten.

Shell functions receive explicit exports as well. Recursive exported values that themselves invoke $(shell ...) are explicitly rejected; GNU's special export-recursion fallback remains project interpreter work.

#Standalone metadata

Standalone --version prints exactly make 0.2.1 followed by one newline. Standalone --help starts with Usage: make, lists both metadata options, and ends with a newline. Both write to stdout, leave stdin unread, and exit with status 0. Exact-version publication and verification remain recorded separately in the support record.
