This is very interesting as well –

JSTalk is how I imagine AppleScript would be done today, if it was written by a Cocoa programmer who was smitten by Cocoa and Objective-C…

JavaScript OSA is a port of the Mozilla JavaScript scripting system to the Macintosh:

Narwhal aims to be a complete environment for JavaScript on the server, including a standard library (implementing the CommonJS/ServerJS spec), package manager, shell, virtual environments, etc.

It’s a layer on top of the interpreters, so you’ll be able to switch between Rhino, V8, JSC, etc. For now Rhino is the most complete.

It’s still a work in progress, but useful none the less: http://narwhaljs.org/quick-start.html

If you’re looking for a scripting language with simplicity and power look at rebol. It’s closer to Javascript than you may think see

For example you will be able to tweet in one line in command line:

@zachstronaut

I tried doing that too, is probably because jsc is trying to execute the script including the first line with the shebang and stops because it’s not valid js, I haven’t found an alternative, but it would be really cool if we could have js shell scripts.

By default, WSH (Windows Script Host) only executes JavaScript from a file. I’ve written some JavaScript that makes WSH act like an interactive interpreter (read-eval-print loop). There’s a page describing it at: http://waterken.sourceforge.net/web_send/wsh/ The really cool thing about running JavaScript this way is that you’re not confined by the Same Origin Policy, so you can script across web sites. Think of it as a shell for the Web, rather than a shell for your local box.

IMHO, if you need a command-line scripting language, install Python. It has cleaner syntax than Javascript, but has so many similarites that a JS programmer could be comfortable with it in an afternoon.

(and by readline(), I mean readline() in jsc)

FWIW, I think there’s also a readline() built-in for grabbing data from STDIN. So, no native file access, but you can pipe things in. That’s useful at least for using things like JSLint

Anybody here saavy to why this does not work as expected?

create file foo:

#!/System/Library/Frameworks/JavaScriptCore.framework/Versions/A/Resources/jsc
print(‘hello world’);

chmod 755 foo

./foo

no output… ajaxian?!

Any pointer on messing with files and folders ? Some FileUtils equivalent?

I use Rhino on the shell all the time – when I want an interactive JavaScript interpreter. But this is a far cry from having the whole ecosystem of Unix shell commands available to you for your pipelining pleasure. If you want to get around on your system, you need to learn a shell!

though the markup and is there... the two longer pre tags you used appear truncated in this post /System/Library/Frameworks/JavaScriptCore.framework/Versions/A/Resources/jsc $ sudo ln /System/Library/Frameworks/JavaScriptCore.framework/Versions/A/Resources/jsc /bin/jsc
