Re: [feature] did you guys knew that ? is a valid character for function/command name?
This is very bad news for my long-held campaign to introduce '@' as an optional (but one day might be checked) prefix to a parameter, to indicate in the calling line that this is passed by reference. ie if functionWithSideEffects(tInput, @tOutput) then ... should allow the reader to know immediately that 'functionWithSideEffects' takes the second parameter by reference.

Re: [feature] did you guys knew that ? is a valid character for function/command name?
Not quite. We specify pass-by-ref by using '@' in the handler specification; you can't use it in the calling script as Ben did in his example in the email. Ben wants to be able to use the '@' (presumably as an option, with no actual effect) in the calling script, to help remind him that the variable will/may be changed within the handler. -- Alex.

I went to go vote for this bug report/enhancement request, but I can't exactly find it. Are you referring to 741, 3753, 6820, or 6949? BZ#3753 seems the closest although 741 has more accumulated votes (8/1). And 6949 has 5 votes although it's somewhat a side effect of not having a generic ability to specify @ in scripts. And 6820 has more votes than all the others combined, although it deals only with the special case of passing a reference to an array element. -- -Mark Wieder mwie...@ahsoftware.net ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

Re: [feature] did you guys knew that ? is a valid character for function/command name?
If one is interested in speed, it can be quite useful. Also you could write scripts with no functions! Just commands. Return the data in the same variable without copying to another (which happens in functions). It's a different coding style for sure.

Andre - yeah, what Alex said. Both caller and callee need to be fully aware when a parameter is by reference - it's a contract, and needs informed consent on both sides. Currently we have only presumed consent on the part of the caller. On 07/09/2010 17:07, Mark Wieder wrote: I went to go vote for this bug report/enhancement request, but I can't exactly find it. At which point Ben has to apologise for his hyperbole, and admit that long-held campaign means long-held view, but never done anything about it since posting to the now defunct Xtalks mailing list in May 2004. There was a lively (for Xtalks!) discussion, but nothing came of it (except the interesting observation from Doug Simons, who maintains SenseTalk, that he has the reverse; it's the caller that indicates a variable is passed by reference, he allows but ignores @ in the function declaration, only to maintain compatibility with Transcript). At that time I had an idealistic view that extensions to the language were better proposed and discussed in Xtalks first, before specifically proposing that Rev adopt them.
