# Targets:
|
||||
# all: Format, check, build, and test the code
|
||||
# setup: Install build/test toolchain dependencies (e.g. gox)
|
||||
# lint: Run linters against source code
|
||||
# bump-{major,minor,patch}: create a new semver git tag
|
||||
# release-{major,minor,patch}: push a tagged release
|
||||
# format: Format the source files
|
||||
# build: Build the command(s) for target OS/arch combinations
|
||||
# install: Install the command(s)
|
||||
# clean: Clean the build/test artifacts
|
||||
# report: Generate build/test reports
|
||||
# check: Run tests
|
||||
# bench: Run benchmarks
|
||||
# dist: zip/tar binaries & documentation
|
||||
# debug: print parameters
|
||||
#
|
||||
# Parameters:
|
||||
# VERSION: release version in semver format
|
||||
# BUILD_TAGS: additional build tags to pass to go build
|
||||
# DISTDIR: path to save distribution files
|
||||
# RPTDIR: path to save build/test reports
|
||||
#
|
||||
# Assumptions:
|
||||
# - Your package contains a cmd/ package, containing a directory for each produced binary.
|
||||
# - You have cloc installed and accessible in the PATH.
|
||||
# - Your GOPATH and GOROOT are set correctly.
|
||||
# - Your makefile is in the root of your package and does not have a space in its file name.
|
||||
# - Your root package contains global string variables Version and Build, to receive the bild version number and commit ID, respectively.
|
||||
#
|
||||
# Features:
|
||||
# - report generates files that can be consumed by Jenkins, as well as a list of external dependencies.
|
||||
# - setup installs all the tools aside from cloc.
|
||||
# - Works on Windows and with paths containing spaces.
|
||||
# - Works when executing from outside the makefile directory using -f.
|
||||
# - Targets are useful both in CI and developer workstations.
|
||||
# - Handles cross-compiation for multiple OSes and architectures.
|
||||
# - Bundles binaries and documentation into compressed archives, using tar/gz for Linux and Darwin, and zip for Windows.
