JavaScript Shell Scripting
A few days ago, Peter Michaux posted a very promising article concerning xjs. I've long wanted to be able to use JS to write shell scripts (as one would do using bash, python or perl) but it lacked several important features.
Peter has added a File module which wraps Java file operations, and I see this as the first step towards taking JS out of web development. Let's face it, JS is really present in browsers, SSJS is taking off very slowly and even though a few apps use JS for scripting, it's still not mainstream.
The way I dream of JavaScript's future ? As a general purpose scripting language. This means that several things have to be done. First, an easy way of binding whatever library to JS. Second, a CPAN like repository dedicated to JS. There is absolutely no control on how would evolve the latter. The former, however, can be conceived right now.
I'm not really sure if I agree with Peter's choice of Rhino instead of SpiderMonkey, but I guess he has more experience with Java than with C — which is quite the opposite of my own misconceptions. I guess there are pros and cons for each of the choices, but I wonder if it'll be easy to port generic C libraries to JS using Rhino. I must clarify something at this point : I have a deep hatred of Java — it's a kind of zealous religion — and everything that comes near it appears like obscure magic to me.
Nevertheless, I really wish a lot of good things to xjs, and I hope that Peter will take into account the fact that an easy mechanism for porting library is a must-have.
