[lively-kernel] Programmatically dealing with Worlds

[Robert Krahn]

Apologies, this kind of stuff should be directly supported. For now you can
use the snippet below.

Note, rename/copying a world is actually very straightforward, the only
issue that you have to pay attention to is to properly link the bootstrap
script since this is link is relative and needs to change when you change
the location of the world.


Snippet:

function copyWorld(from, to) {
    // usage like:
    //   copyWorld('users/robertkrahn/foo/world.html',
'users/robertkrahn/world.html');
    var toURL = URL.root.withFilename(to),
        htmlSource = URL.source.asWebResource().get().content,
        html = $($.parseHTML(htmlSource, document, true/*keep scripts*/)),
        bootstrapModuleURL = new URL(module("lively.bootstrap").uri()),
        bootstrapFile = bootstrapModuleURL.relativePathFrom(toURL);
    html.filter('script[src]').attr('src', bootstrapFile);
    var newHTML = html.toArray().map(function(ea) { return
Exporter.stringify(ea); }).join('\n');
    toURL.asWebResource().put(newHTML);
}
