JavaScriptCore via Terminal

Just a quick one, maybe only for a new Mac comer as I am, I found truly annoying I have already Python, Ruby, and even PHP everywhere available in my command line but not JavaScript?

What The Fuck

Even Windows runs .js files natively and since ages, I wonder why on earth after I have downlaoded the whole XCode SDK "my JavaScript" was not there available for all my needs.

OK, OK, node.js is already on /bin, linked and working properly, but now I have the system default JavaScript Engine that comes automatically with WebKit or the "IE for Mac" aka Safari.

How to link jsc to bin folder

A title that produces zero outcome on Google, could be hopefully better addressed via this blog, and this is how I have solved:

sudo ln -F /System/Library/Frameworks/JavaScriptCore.framework/Versions/Current/Resources/jsc /usr/bin

The Current folde ris the link to the latest one, all those threads about the ..../A/... folder are not automatically updated if A becomes B, as example.
So, now I can type jsc wherever I am and use JavaScript power whenever I want, writing just quit() anytime I need.
I hope this helps, it took a while for me to sort it out.

Formaldehyde JS - The Circle Is Close

As announced in Ajaxian, I have created Formaldehyde JS with exactly the same Zero Config logic.

We put this file before everything else and that's it, Formaldehyde will automatically decide how to show errors in a wide range of browsers:

• Chrome
• Firefox
• Internet Explorer 5, 5.5, 6, 7, 8 with or whout console
• Opera
• Safari

Logs will naturally degrade until the most primitive alert but hey, Formaldehyde is for debug and development environments, not for production.

Enjoy ;)

JScript Console - A Simple One

After I've read Ajaxian post about JavaScript as a command line scripting language I thought it could be interesting to know how to create the first Windows console.

The console.js File

function print(text){
    WScript.StdOut.WriteLine(text);
};
function quit(){
    WScript.quit(1);
};
while(!WScript.StdIn.AtEndOfStream){
    try{
        eval(WScript.StdIn.ReadLine());
    }catch(e){
        print(e.message);
    };
};
WScript.StdOut.WriteLine("bye!" + "\r\n");

The console.bat Launcher

@echo off
cscript console.js

A double click in latter file, and that's it, the most basic native JScript console ever has landed in your PCs - enjoy :)
