makefile - 运行多个进程(多个监视命令)

Question

我正在尝试制作一个执行多个命令的 Makefile。例子:

script:
  cat scripts/*.js > public/scripts/scripts.js

vendor:
  cat vendor/*.js > public/scripts/vendor.js

watchStyles:
  stylus -w -u nib styles/styles.styl -o public/styles

watchScripts:
  watchr -e "watch('scripts/.*\.js') {system 'make scripts'}"

watchVendor:
  watchr -e "watch('vendor/.*\.js') {system 'make vendor'}"

现在我必须打开3个终端，这很烦人。如何通过 make watch 只运行一个?

watch: watchStyles watchScripts watchVendor

Answer 1

如果您使用 GNU make 然后 -j option allows it to build targets in parallel ，例如:

make -j4 watchStyles watchScripts watchVendor
