Supposing you've found a golang boilerplate and you want to relocate the project under your name. Here's a makefile to help you do so.
Note: A makefile is a file containing a set of directives used by a make build automation tool to generate a target/goal.
First, let's declare some variables for further use.
GITHUB := "github.com"
PROJECTNAME := $(shell basename "$(PWD)")
PACKAGENAME := $(GITHUB)/$(shell basename "$(shell dirname "$(PWD)")")/$(PROJECTNAME)
GOBASE := $(shell pwd)A code snippet for running coverage tests is shown below. It is triggered by running make test
.PHONY .SILENT: test
## test: Run coverage tests
test:
# Example: make test
@echo " *** Running Coverage Tests ***"
$(GOBASE)/test.sh
@echo " *** Completed *** "The author has built a shell script to handle the coverage tests. Here we just need to call test.sh
A simple test is required to see if a target path is provided or not. A sample usage would be make relocate TARGET=github.com/wingkwong/myproject
@test ${TARGET} || ( echo ">> TARGET is not set. Use: make relocate TARGET=<target>"; exit 1 )Then, we need to have our variables escaped as we will to sed to perform the replacement
$(eval ESCAPED_PACKAGENAME := $(shell echo "${PACKAGENAME}" | sed -e 's/[\/&]/\\&/g'))
$(eval ESCAPED_PROJECTNAME := $(shell echo "${PROJECTNAME}" | sed -e 's/[\/&]/\\&/g'))
$(eval ESCAPED_TARGET_PACKAGENAME := $(shell echo "${TARGET}" | sed -e 's/[\/&]/\\&/g'))
$(eval ESCAPED_TARGET_PROJECTNAME := $(shell basename "$(shell dirname ${TARGET})" | sed -e 's/[\/&]/\\&/g'))
$(eval ESCAPED_PARENT_DIRECTORY:= $(shell cd ../ && pwd | sed -e 's/[\/&]/\\&/g'))
$(eval ESCAPED_PARENT_DIRECTORYNAME:= $(shell basename $(ESCAPED_PARENT_DIRECTORY)))We need to replace the package name github.com/author/project with the desired one.
@grep -rlI '${PACKAGENAME}' --include=*.go ./ | xargs -I@ sed -i '' 's/${ESCAPED_PACKAGENAME}/${ESCAPED_TARGET_PACKAGENAME}/g' @We also need to replace the project name project with the desired one.
