I’ve come to ruby and rails from php. By and large I’m loving the switch but a few things I miss. One of the big ones is that ruby evaluates an empty string and the number 0 to be true in boolean expressions.
So I wrote a quick way around it.
class String def to_b self.length > 0 end endclass Integer def to_b self != 0 end end
Now if you want to check if a string or integer would be considered false by PHP just call to_b on it. Example:
"Desu".to_b #true "".to_b #false 10.to_b #true 0.to_b #false
Simple but it does the job .
Update: You can just use empty?
for strings
