[REBOL] Re: [BUG?] read-io & write-io or Wait or is TCL better?

Hi Petr, On Thursday, August 7, 2003, 1:19:54 PM, you wrote: PK> OK, that is just presumption. Novice user will not know that ... we are They should.

In this case, is the documentation that needs to explain clearly what the purpose of these functions is. I don't see why they would need to be changed, considering that they are not even meant to be used by a "novice user" as you say. :) (They should be avoided by the expert user too, because REBOL offers a better way to do the same thing. You have to have a very good reason to use them.. :) PK> Why should read-io "append" to buffer? Because that could be exactly what you need. And while this behavior does not cause any problem to someone that does not need it (you just provide an empty buffer), the contrary is not true: if you wanted it to append (because the first packet is not enough for you to process, for example) and it cleared the buffer you would be forced to work around it (and at least you'd need to copy your data, which could be undesirable if you have to copy it again later while or after parsing).

New users just need correct documentation. Or, better, to avoid this kind of "unrebolish" functions. ;-) PK> You could use another series for its further storage ... :-) REBOL is fast because you can write efficient programs with it. Let's not break this rule. ;-) Regards, Gabriele. -- Gabriele Santilli <[g--santilli--tiscalinet--it]> -- REBOL Programmer Amiga Group Italia sez. L'Aquila --- SOON:
