obsidian-markdown/Makefile

# This file is intended as a starting point for a customized makefile for a Go project.
#
# 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.
