From port-modules(5):
lang/go Adds Go toolchain support. Requires ALL_TARGET to be set
to canonical Go import path of port. (Module sets it
automatically for ports that use GH_ACCOUNT and GH_PROJECT
macros.)
During execution of post-patch target module moves source
code from ${MODGO_SUBDIR} to ${WRKSRC}, subdirectory of
${MODGO_WORKSPACE} - specially-crafted Go workspace located
at ${WRKDIR}/go. During do-build module calls ``go
install'' with GOPATH set to ${MODGO_WORKSPACE}, runs its
output through sed to prevent writes outside WRKDIR sandbox
and sends output to sh(1). During do-install it copies
executables from ${MODGO_WORKSPACE}/bin to ${PREFIX}/bin,
and/or directories ${MODGO_WORKSPACE}/pkg and
${MODGO_WORKSPACE}/src to ${PREFIX}/go, depending on
MODGO_TYPE contents.
Sets BUILD_DEPENDS, RUN_DEPENDS, ALL_TARGET, TEST_TARGET,
ONLY_FOR_ARCHS, SEPARATE_BUILD, and WRKSRC.
Defines:
MODGO_TYPE Type of port. May be any combination of:
bin ordinary binary, which should be
installed to ${PREFIX}/bin,
lib library, which should come with
source code.
Defaults to bin.
MODGO_WORKSPACE Path to Go workspace set up for port build
process. Defaults to ${WRKDIR}/go. See
Go documentation for details.
MODGO_SUBDIR Path to Go source code within port's
sources tarball. Defaults to ${WRKDIST}.
MODGO_SETUP_WORKSPACE
Commands setting up Go workspace for
building ports. By default, happens
during execution of post-patch target.
MODGO_BUILDDEP Controls whether contents of
MODGO_BUILD_DEPENDS are appended to port's
BUILD_DEPENDS. Defaults to Yes.
Additionally defines MODGO_PACKAGES, MODGO_SOURCES and
MODGO_TOOLS (paths for installed Go packages, sources and
tools respectively), MODGO_CMD and MODGO_FLAGS (source code
build command and flags passed as its arguments),
MODGO_BUILD_CMD and MODGO_TEST_CMD (commands for building
and testing go packages; normally called with canonical Go
package names as arguments),
MODGO_{BUILD,INSTALL,TEST}_TARGET and
MODGO_{BUILD,RUN}_DEPENDS.
