I am wondering why you find this omission so shocking? When I ran
into the need for a function like this myself, I just added it in my
own app and moved on:
function escape(text)
return (text or ""):gsub("&", "&"):gsub(">",">"):gsub("<","<")
end
Or this alternative:
function escape(text)
local escaped = { ['<']='<', ['>']='>', ["&"]='&' }
return text:gsub('[<>&]', function(c) return escaped[c] end)
end
print(escape('2 < 3 & 10 > 9'))
