有一个小需求，将一个目录包括子目录中的coffee文件批量转换到另一个指定的目录中，同时保挂子目录的结构。改了一个类似的Makefile。发一下备忘：

coffeeBaseDir=coffee/
coffeeDir=$(abspath $(coffeeBaseDir))
jsBaseDir=js/
jsDir=$(abspath $(jsBaseDir))

jsFile=$(shell find $(coffeeBaseDir) -type f -name *.coffee | sed 's@^$(coffeeBaseDir)@$(jsDir)/@g' | sed 's@\.coffee$$@\.js@g')

jsDeploy: $(jsFile)

$(jsDir)/%.js: $(coffeeDir)/%.coffee
	@mkdir -p `sed 's@/[^/]\+$$@/@g' <<< '$@'`
	coffee -bp $< > $@

test:
	@echo $(jsFile)

clean:
	@rm js -fr
	@echo 'clean success!'

测试结果：

>find coffee -type f
coffee/abc.coffee/3.coffee
coffee/abc.coffee/1.coffee
coffee/abc.coffee/2.coffee
coffee/p1/3.coffee
coffee/p1/1.coffee
coffee/p1/2.coffee
coffee/p2/3.coffee
coffee/p2/1.coffee
coffee/p2/2.coffee
coffee/p3/3.coffee
