Lyndon is like Johnson. But for MacRuby. And with JavaScriptCore.
$ rip install git://github.com/defunkt/lyndon.git
Successfully installed lyndon (41548d2)
$ lyndon
js> 1 + 1
=> 2
js> function name() { return "lyndon!" }
=> undefined
js> name
=> function name() { return "lyndon!" }
js> name()
=> "lyndon!"
js> Ruby.puts('Ruby, I presume.')
Ruby, I presume.
=> undefined
js> Ruby.File_read('hi.js')
=> "// this is hi.js\n"
Stuff like that.
$ lyndon test.html
js> Lyndon.require('jquery.min.js')
=> true
js> jQuery('#hi').html()
=> "Hello."
js> jQuery('#hi').html('Hi.')
=> [object Object]
js> jQuery('#hi').html()
=> "Hi."
=> "[object HTMLBodyElement]"
js> document.body.innerHTML
=> "\n <h1 id=\"hi\">Hi.</h1>\n \n\n"
$ cat examples/index.html | lyndon
<html><head>
<title>It worked!</title>
</head><body>
<div id="content">
<div id="hi">Hello world!</div></div>
</body></html>
Note that the <div id="hi">Hello world!</div></div> does not exist
in examples/index.html - it's added at runtime by
JavaScript. JavaScript that strips itself out and changes the
<title>.
Seriously.
If you want:
$ macirb
>> require 'lyndon'
=> true
>> Lyndon.eval('1 + 1')
=> 2
>> r = Lyndon::Runtime.new
=> ##-<Lyndon::Runtime:...>
>> r.eval('var name = "chris"')
=> undefined
>> r.eval('name')
=> "chris"
That's basically it.
