No, no, I'm swinging *back* from that

Post #126,246 by FuManChu 11/18/03 5:42:16 AM Reply	No, no, I'm swinging back from that ..on the pendulum backswing. Been there, do that constantly. It's just not always necessary. Sometimes you _should_ write "for eachJob in currentSet". Anything more descriptive would just get in the way.

Post #126,690 by jb4 11/19/03 11:14:20 AM Reply	Sorry, No Sale That would imply that you declared a variable called 'eachJob'. I'd love to see how you commented that... \n Job eachJob; // and I will describe this how?!?\n Even in this example, the Job you are working with has a specific putpose and use in the program. This purpose and use has a name, and if you enumerate that, the variable magically names itself in such a way that event the most casual observers (ar a complete idion...like me) can figure out what it does.

Post #126,691 by ben_tilly 11/19/03 11:24:24 AM Reply	That would imply that YOU don't use dynamic languages In Perl: `for my $each_job (@job_list) { # Do something, like this... $each_job->start(); }` You will note that no declaration exists. And a comment about what you mean by a variable that is in scope for 2 lines which is clear in context is silly to the point of stupidity. (Why add the maintainance overhead if its purpose is that clear?)

Post #126,717 by Simon_Jester 11/19/03 3:12:33 PM Reply	My two sense... we usually had most logic than a simple ArrayList or Vector in our collection classes... so: JobCollection allJobs; Job aJob; Job aProgammer; // Better still Then: foreach (allJobs.begin(), allJobs.end(), <function call>); (Or you could simply walk through them) for (allJobs::iterator i= allJobs.begin(); i != allJobs::iterator.end(); i++) { // DO something } // The each aspect is implied - so it falls out.
Post #126,710 by jb4 11/19/03 1:59:05 PM Reply	Well, I write in what I'm paid to write in. Right now that's C...with a migration to C++ in the offing. Most of my work is in the embedded arena. The closest thing I have to a script language is the shell of whatever platform we're using for cross development (mostly Windows, which as we all know, doesn't have a shell; some work is going to happen on Linux [Hoo-RAY!], and I'm furiously learning bash, because csh sux!). Some talk of perl work; so I'll be availing myself of the collective's expertise soon enough. Oh, yeah...and MAKE files...they're sorta a script....

Subtle difference. ;) I truly appreciated the power of anonymity in dynamic languages today, when I wrote: `categories = {}.fromkeys(categories).keys()` which removes duplicate items from the sequence named 'categories'. The {} creates a new, anonymous dictionary, which is first populated with .fromkeys(), then immediately consumed by .keys(), which returns the list I want. Of course, if I did this regularly, I would put it in a named function, like 'flatten' or 'dedupe' or something. But you get the idea.

Post #126,747 by admin 11/19/03 5:14:44 PM Reply	I don't. Well, I do, but I also write in a lot of other things, too. Because learning languages other than the ones I use at work gives me a new appreciation (or depreciation, for that matter ;-) for how they operate, and new insights into how to use them creatively to solve problems.
