Functional programming?
by Rick Hedin 16 May '02

16 May '02

Hello. My friends are trying to convince me of the value of functional programming. Writing safer and clearer programs sounds good, but I am not inclined to learn Haskell. Xotcl is a pretty flexible beast. Can I do functional programming in it? It seems as though classes are a variety of object in Xotcl, so that will be an advantage for passing classes around, but what else am I missing? I suspect that Gustaf and Uwe thought about functional programming when they designed their beast. Can I find out what their thoughts were? Regards, Rick

Panic in xotcl 0.9.4
by Zoran Vasiljevic 06 May '02

int XOTclSelfDispatchCmd(ClientData cd, Tcl_Interp *in, int objc, Tcl_Obj *CONST objv[]) { XOTclObject *self; int result; if ((self = GetSelfObj(in))) { result = callMethod((ClientData)self, in, objv[1], objc, objv+2, 0); } else { result = TCL_ERROR; panic("Self Dispatch: could not resolve self"); /** Urks !? **/ } return result; } Do we need to trigger panic (i.e. crash program) when self cannot be resolved ? Or is is sufficient just to return error ? Cheer's Zoran
