使用正则表达式解析命令和参数？

Question

I have a small Ruby CLI which should take a command and some arguments.

For example, I should be able to do:

attribute value

or:

attribute (value1, value2)

or:

attribute (value1, value2) and attribute2 (value3, value4)

or any combination.

I'd like to get back something like:

[['attribute', ['value1', 'value2']], ['attribute2', ['value3', 'value4']]]

I came up with this regex

(\b[a-z_]{1}\w+)\s{1}\((.*?)\)

which gets me partially there, in that it matches the attribute and both the values (as a whole, like [['attribute', 'value1, value2']] , but it doesn't match something like attribute value .

I dont know how extensive of input you require, but something like this might do the trick. It works similarly to the shell getOpts.
