Redefine the error handling function while you do the check, or use a protected call? Actually, has anybody implemented a try/catch/finally doobry that'd make this kind of thing slightly nicer?Please can someone tell me if Lua can tell if a file exists? I've tried testing for for a valid return from io.open(), but if the file doesn't exist, Lua throws up a default error, never mind trying to run my own handling code... The only fuction that I can find that even looks like it might help is io.type(), and that gets a nil even if the file does exist.
