!addcom haha have fun

Nightbot can only test the first word in a message for a command. So you need to anticipate which words chatters might start their messages with and then add multiple commands with those words as the command names. For example:

!addcom hello $(eval /haha/i.test(decodeURIComponent("$(querystring)"))?"have fun":" ")
!addcom hi $(eval /haha/i.test(decodeURIComponent("$(querystring)"))?"have fun":" ")
!addcom no $(eval /haha/i.test(decodeURIComponent("$(querystring)"))?"have fun":" ")
