I wanted to contribute a little to this thread. As flay mentioned, your heart is clearly in the right place. But (yes, there is a 'but...'), it is very important to keep an open mind. One of perl's major colloquialisms or mottos is "TIMTOWTDI" or, "There Is More Than One Way To Do It," or, as I like to say, "Several Methods Exist For The Accomplishment Of Your Task" SMEFTAOYT. < grin >
Im going to give you a couple examples, and I hope the rest of the monks realise I'm not trolling here.
Languages like Python and Pascal are excellent languages to teach with. I think most professional programmers learned on one of those, though many also learned on C. Perl is often very confusing to novice programmers because it is so loosely typed, and things can appear vague. In some cases, "One Way To Do It" is easier to understand than others.
While Perl is a truly cross-platform language, sometimes its necessary to have a cross-platform compilable program. I work daily in the OpenNap server package, which is written in C. More information is available on my home node. It simply isnt practical to write that software in perl. Sure, perl could do it, and there *is* a napster server written in perl, but one begins to wonder why you would use perl for that task rather than something a little more appropriate. (as an aside, pircd /* an IRCd written in perl */ is excellent!)
I had a question, a couple hours ago, about behaviour of the Bourne-Again SHell (bash) in unix. I was trying to figure out what this command would do:
Would it overwrite all the files in the directory with "foo"? Would it overwrite the first file in the directory? To test it, my solution was thus:
The first line is my example. Sure, I could have done that in perl:
But one has to wonder why somebody would go to the trouble to do that when, in this case, clearly, its quicker and more concise to whip it up in a shell oneliner.
I love perl just as much as the next guy. I've got the bumper stickers and t-shirts. Im a #perl chanop and the whole shebang. Sometimes, however, perl is just not the right tool for the job. Sometimes, something else can do that job better than perl. Perl is not the biggest programming language out there, or the most popular, or the best, or any of that. Perl just happens to be a language that we all love a great deal.
Before I step down from this Soap Box, I wanted to give you a link thats been tossed about this great perl community of ours for a while.
Keep the shiny side up,
p.s., for anyone interested, the shell loves you. we get "ambiguous redirect" in bash if we pass it '*' as our redirect filename.
