Re: [jira] Created: (COUCHDB-573) Regex capture problem in emit functions

[Vlad GURDIGA <gu...@gmail.com>]

If you intended to refer to the first captured group you probably want
$1 instead of $0*, but before that you would need to create a capture
group with round brackets "()", like:

 doc.EntityType.replace(/([A-Z])/g, ' [$0]');

which would replace each capital letter with itself in square brackets.

Good luck!
