I'm able to capitalize the first letter of my string using:
str:gsub("^%l", string.upper)
How can I modify this to capitalize the first letter of every word in the string?
I wasn't able to find any fancy way to do it.
str = "here you have a long list of words"
str = str:gsub("(%l)(%w*)", function(a,b) return string.upper(a)..b end)
print(str)
This code output is Here You Have A Long List Of Words. %w*
could be changed to %w+
to not replace words of one letter.
Fancier solution:
str = string.gsub(" "..str, "%W%l", string.upper):sub(2)
It's impossible to make a real single-regex replace because lua's pattern system is simple.
