\b
#Word cannot end with @ (made to catch emails)
(?![@])
#We accept any number of slugs, given we have a char after the slash
(\/)?
#If we have endings like ?=fds include the ending
(?:([\w\d\?\-=#:%@&.;])+(?:\/(?:([\w\d\?\-=#:%@&;.])+))*)?
#The last char cannot be one of these symbols .,?!,- exclude these
(?
