Quickie: Ruby's string modulo method (%)
Posted by theBlatherskite
Just came across this in Ruby today:
>> tmpl = "I am a stored %s with %d replacements"
=> "I am a stored %s with %d replacements"
>> tmpl % ['template', 2]
=> "I am a stored template with 2 replacements"
>> tmpl % ['fish', 17]
=> "I am a stored fish with 17 replacements"
Handy way to save formatted templates for printfing later, but a bit strange the first time you see the % method applied to a string.
