You Used Perl to Write WHAT?!

Esther Schindler writes "Developers spend a lot of time telling managers, 'Let me use the tool that's appropriate for the job' (cue the '...everything looks like a nail' meme here). But rarely do we enumerate when a language is the right one for a particular job, and when it's a very, very wrong choice. James Turner, writing for CIO.com, identifies five tasks for which perl is ideally suited, and four that... well, really, shouldn't you choose something else? This is the first article in a series that will examine what each language is good at, and for which tasks it's just plain dumb. Another article is coming RSN about JavaScript, and yet another for PHP... with more promised, should these first articles do well."

Both sides...

I always see both sides of the 'right tool for the job' problem.

Having the right tools is great for current productivity, but it's hell on expenses and new recruits. If you use a different tool for every job, you need to maintain all those tools and a task force that's able to use all of them. Sometimes the 'right tool' is one that fits the company as well as the job.

My favorite example

My favorite "You did WHAT in perl?" response is: On several projects, when there were portability problems, I've created a Makefile entry that runs a "man foo" command and pipes the data to a perl script, which generates C files for that system. It's typically just header files, but sometimes also a few .c files with data structures and/or simple functions to intercede with variant library routines.

It's fun to watch people's reaction when they realize that "You wrote a perl script that reads the manual and generates the code?" I just respond something like "Uh, yeah; you got a problem with that?"

Especially fun has been the couple of discussions in which I expressed a great deal of skepticism of various "AI" claims. Then someone brings up the fact that I write perl programs that read English-language docs and generate code from them. They're obviously puzzled by the fact that I do this while looking skeptically at "AI" proposals. It's like they expect me to just shrug and write other impossible things in perl.
