[lively-kernel] Migrate xhtml files from lively(-kernel) to latest lively

Hi,

After installing the latest lively-web locally from
https://github.com/LivelyKernel/LivelyKernel, I webdav copied some projects
from my older playing with Lively in
http://lively-kernel.org/repository/webwerkstatt/users/mzimmerm/ to the new
installation.

But the projects do not open in the latest code - looking at the xhtml code
they are generally <meta id="LivelyMigrationLevel"><![CDATA[4]]></meta>. I
debugged through the bootstrap.js and I think there is something failing
when the build() element fails to append to the body, but that is just a
guess I was unable to follow through.

Is there a way to convert/migrate older xhtml files? I do not have anything
of importance, so no problem if not, but perhaps there is something known I
can do,

thanks
milan

Hi, Milan --

You can find a migration script here:

http://lively-web.org/users/robertkrahn/2015-03-04_migrate-lively-kernel-worlds.html

When you run it locally and change the hostname / portname of "newURL"
accordingly you can migrate to your own server or you can migrate your
worlds to lively-web.org.

Best,
Robert

Thanks Robert,

this worked great to copy all my files from lively-kernel to my local
installation.

I have a somewhat related question that should go into it's own subject but
let me ask it here: When running the process I wrapped the code into a list
of all files I had in that directory and subdirectories. I created that
list manually, but originally I thought to do something like this on top of
the script

fs = require('fs');
files = fs.readdirSync("."); // well I realize we are in Webdav so this is
not right but sufficient for the question context I think
// process the files

Basically, my question is, (and I realize it is vague): is there a way for
the JS workspace to act as a Nodejs console as well - being able to require
Nodejs modules in the JS workspace, call the module exposed methods, and
process the results in the JS workspace?

Thanks
Milan

Hi, Milan --

You can indeed open a Server workspace

[image: Inline image 1]

Then you can run code like

var fs = require('fs');
process.cwd(); // /home/lively/LivelyKernel
var files = fs.readdirSync("./users/mzimmerm"); //
config.js,images,projects,start.html

Alternatively, to use webdav to list files (from a normal workspace):

var dirContent = URL.root.withFilename("users/mzimmerm/")
.asWebResource().getSubElements(/*optional: depth*/)

dirContent.subDocuments // WebResource(
http://lively-web.org/users/mzimmerm/config.js), ...
dirContent.subCollections // WebResource(
http://lively-web.org/users/mzimmerm/images/), ...

Best,
Robert

Thanks Robert for the details on both methods!
