Class Method Details

.parse(argv) ⇒ String, Array

返回cmd 和 参数列表 # 将参数初步分解，便于后续处理 如：argv = [command zzzz -u sdfsd sdf –mmmm yoo ssss qqq –test asdfa asd ad f –xxx asd as dfa –yoo=“ajsdaf” –ppp -abc] 分解为：command, [zzzz], [[-u, sdfsd, sdf], [–mmmm, yoo, ssss, qqq], [–test, asdfa, asd, ad, f], [–xxx, asd, as, dfa], [–yoo, “ajsdaf”], [–ppp], [-a], [-b], [-c]]

初步解析参数

Parameters:

  • argv (Array)

Returns:

  • (String, Array, Array)
