前言
Director 是一个Python的类库用来开发命令行工具的插件,利用它可以很方便的添加新的功能。
下面是一个简单的例子:
#!/usr/bin/env pythonimport exceptionsimport sysfrom director import ActionRunnerfrom director.filter import ExceptionFilterfrom director.filter import Filterif __name__ == '__main__': # Create and use exception filters
# Note you don't have to use filters. If you don't pass filter in
# to ActionRunner.run filters won't be used.
filter = Filter()
filter.register_filter(ExceptionFilter(exceptions.IOError, "TEST %s"))
filter.register_filter(ExceptionFilter(exceptions.TypeError, "NO! %s")) # 'actions.package' is the package that holds the allowed plugin actions
ar = ActionRunner(sys.argv, 'actions.package')
ar.run(filter)·
