Extract all case when entries

Ruby
1

Hi:

consider

def foo(i)
case i
when ‘foo’,‘bar’,
‘bla’
call_this
when ‘yo’
call_ok
end
end

Is there a simple way to programmatically get all entries of a given
case menu?

So I would get an array like:

[‘foo’,‘bar’,‘bla’,‘yo’]

?

The only way I could think of to do that would be to read and parse the
text file containing the code. Then it’s a bit of regex to isolate the
case statement and pull out the entries.
