Question

I’m currently fighting a weird javascript regex problem. I’m trying to match all characters between / or the end of input. For example this string

admin/item/get

should be matched as:

[ 'admin', 'item', 'get' ]

I don’t really care if / is part of the match or not, so this result would work for me too:

[ 'admin/', 'item/', 'get' ]

To match the input string s I’m using the regex

s.match(/.+?[\/$]/g)

which results in

[ 'admin/', 'item/' ]

To my understanding the end of input $ is not matched in this character set.

When I try to match only the end of input using the regex s.match(/.+?$/g) I’m getting the expected result [ 'admin/item/get' ]. But placing the $ in a character set s.match(/.+?$/g) the match call returns null.

Any help appreciated…

Btw: I’m using node.js 0.8.20

Answer 1

Because $ is treated as a character when placed inside a character set. This should do it though, it uses an alternation inside a non-memory capturing group and thus restores the meaning of $ to be the end-of-subject:

s.match(/.+?(?:\/|$)/g)

["admin/", "bla/", "bla"]

As mentioned in the comments:

s.split('/')

["admin", "bla", "bla"]
