Does Lua provide a function to make the first character in a word uppercase (like ucfirst in php) and if so, how to use it?
I want keywords[1]
to be first letter uppercase. I've read that string.upper
does it but it made the whole word uppercase.
There are some useful string recipes here, including this one. To change the first character in a string to uppercase, you can use:
function firstToUpper(str)
return (str:gsub("^%l", string.upper))
end
