For the first letter of a sentence:


foo = string.gsub ("i like you", "^.", string.upper)

print (foo)  --> I like you


To capitalize every word you can use a (rather obscure) frontier pattern, like this:


foo = string.gsub ("i like you", "%f[%a].", string.upper)

print (foo)  --> I Like You


In both cases I am using a regular expression to find what we want to capitalize. Then we pass down the standard function string.upper to string.gsub, and that turns the matching text into upper case.
