Using Named Captures with regex match in Ruby's case…when?

Question

I want to parse user input using named captures for readability.

When they type a command I want to capture some params and pass them. I\'m using RegExps in a case s

Answer 1

named captures set local variables when this syntax.

regex-literal =~ string

Dosen't set in other syntax. # See rdoc(re.c)

regex-variable =~ string

string =~ regex

regex.match(string)

case string
when regex
else
end

I like named captures too, but I don't like this behavior. Now, we have to use $~ in case syntax.

case string
when /(?.)/
  $~[:name]
else
end
