Hi John,
thanks for the pointer. That has gotten me a bit farther. I'm running into
a new set of problems. The keys of a hash are frozen, so doing:
munge do |value_hash|
value_hash.inject(value_hash) do |memo,(key,value)|
key.gsub!(/_/, '-')
memo
end
end
Gives me:
Munging failed for value {...} in class properties: can't modify frozen
String
I see you are setting a new key=>value pair (and I guess I'd delete the
old), but when I try that I get:
Munging failed for value {...} in class properties: can't add a new key
into hash during iteration
I can't imagine this is the first time somebody has tried this, but haven't
found anything in the code base.
Geoffrey
