解析参数列表中用逗号分隔的逗号分隔值

Question

So i have this regex:

=([0-9A-Za-z_-]+),?

and i need have a string like:

foo=bar,pine=apple,tree,bar=bie
or
foo=bar,pine=apple,tree
or 
pine=apple,tree

the regex works for cases where i only have 1 value. but since we have comma's in the list of values for the key. the regex just craps out and my code does half of what i want it to do but doesn't get the 2nd value.

How do i fix my regex to take both values regardless of where in the string it is? alone, between 2 others, at the end.

i tried some stuff but couldn't figure it out.

Attempt 1:

=([0-9A-Za-z,_-]+),=?

In this case, it matches the one where it's in the middle but it fails on the others because = does not exist.

Attempt 2:

=[0-9A-Za-z_-]+([,]+[0-9A-Za-z_-]*),?

Matches too bar,pine and tree,bar for example

EDIT::

This seems to work maybe....

=('[0-9A-Za-z,_-]+'),*|=([0-9A-Za-z_-]+),*

if i use quotes for multi values..

You can split on variable names - that will leave only the values:

s := regexp.MustCompile("[^,\\s]+=").Split("foo=bar,pine=apple,tree,bar=bie", -1)
fmt.Println(s)
# => [ "bar", "apple,tree", "bie"]
