The real benefit to marking parameters is when you use variables within a function that are defined outside the function. You could make an argument that it's poor practice to do so, but there it is. I guess you could prefix every other kind of variable instead. Also, when you are choosing names for your parameters marking them with some universal prefix is an easy way to avoid naming collisions.
Does anyone really port ActionScript to PHP and Perl or did you just mean working in both languages individually? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mike Keesey Sent: Friday, August 18, 2006 8:25 PM To: 'Flashcoders mailing list' Subject: RE: [Flashcoders] vars with $ I have seen others do it, or mark parameters with a "p_". I prefer not to mark parameters in any special way. I mark private variables with "_", so those are already distinct. And if I have a function that's so long that I can't see the top from somewhere in the body, it's well past time to cut it down into more manageable chunks. Plus, using "$" makes it more confusing when switching between PHP or Perl (or another language that uses "$" to mark all variables) and ActionScript. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Tom Lee Sent: Friday, August 18, 2006 1:38 PM To: 'Flashcoders mailing list' Subject: RE: [Flashcoders] vars with $ I've used it to indicate arguments in a function to clarify the origin of the variable, like this: function myFunc($arg1,$arg2){ trace($arg1+" : "+$arg2); } I don't know where I picked that up, but for me it makes the code easier to read since you know immediately they are arguments. I've seen people use the underscore for the same purpose, but that can confuse things since ActionScript uses that for some native properties (_x,_y). Does anyone else do this, or am I just in my own little universe? _______________________________________________ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com _______________________________________________ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
