The State of Scripting Languages
Esther Schindler writes to tell us that Lynn Greiner has another look at the state of the scripting universe as a follow on to the same topic three years ago. Greiner talks to major players from each of the main scripting languages (PHP, Perl, Tcl, Python, Ruby, and Javascript) to find out the current status and where they are headed in the future. "The biggest change since 2005 has been the growth of richer Web applications that perform more of their computations in the browser using JavaScript. The demand for these applications has forced developers to learn and use JavaScript much more than before. There's also been a lot of interest in Ruby, another dynamic language, spurred by the release and growth of Ruby on Rails. As a result of these changes, many developers are becoming more comfortable with dynamic languages."
I am getting more comfortable with Javascript, though I still think DHTML and CSS are fundamentally fucked, and it really is time, if this web delivery of apps thing is for real, to find some more rational means of actually dealing with dynamic content.

This essentially summarizes the reasons I prefer to use Perl: the quality of the implementation, and the good libraries. However, there is a dark side that we Perl lovers don't talk about much, which is that although Perl has good quality and good libraries, many of the libraries are not of good quality. My purpose here isn't to name names and rip into individuals who have contributed open-source code to CPAN out of the goodness of their hearts, but honestly, some of the code on CPAN is of very low quality and/or very poorly maintained. Quite a few CPAN libraries are basically glue that interfaces to some C code, and when you look at some of that C code, it looks like examples of the worst coding practices of the 1980's, before the internet existed, and before it really registered on coders' consciousnesses that buffer overflows, etc., were not just bugs but security holes. I've had a couple of bad experiences where I hitched my wagon to a particular CPAN module, and later had serious problems because that module was not actively maintained. E.g., crippling bugs would go unfixed for a year at a time.
On the other hand, I'm not sure that any of the other scripting languages come off any better. What the article says really is true: the base implementations of the other scripting languages are really not anywhere near as solid as Perl's is -- probably partly because Perl is so much older than the others, and therefore more mature. But this may change a lot in the future. Perl 6 is eventually going to be ready for prime time, and there will be a certain amount of chaos and confusion and bugginess at that point, as everyone adapts to the new environment. Also, Perl's head-start in terms of maturity will start to mean less and less as time goes on and the other scripting languages start to get more mature.
Find free books.
but I jumped ship for Python a long time ago. I think most Perl hackers have done the same, or picked up Ruby.
I really don't get it. I know Perl inside and outside. Last year I learned Python, and currently I'm reading a book on Ruby. But that doesn't make me forget Perl, so why not use it when it fits the problem being solved. Additional languages are new tools to add to your toolbox, but they don't remove your old tools. Why stick with one language when you can use all of them as you see fit?
