回答1:

Try this regular expression:

local email = "email@email.com"
if (email:match("[A-Za-z0-9%.%%%+%-]+@[A-Za-z0-9%.%%%+%-]+%.%w%w%w?%w?")) then
    print("VALID EMAIL")
else
    print("INVALID EMAIL")                
end

Use regular expression pattern for checking email.

Use this "[A-Za-z0-9%.%%%+%-]+@[A-Za-z0-9%.%%%+%-]+%.%w%w%w?%w?"

Try this:

local pattern = "[%w][%p][@][%w]+[.][%w.]+[^.]+"

return value ~= nil and #value >= 1 and #value <= 63 and istring.is_ascii(value) and not not value:match(pattern) and #value:match(pattern) == #value

Ex: email@email.com email@email.com.br
