Hey guys,
What is the recommendation for using Ruby’s standard libraries in
Silverlight applications?
Should the lib be copied to the project dir? should a reference be added
to
the manifest? some other technique?
Thanks,
Shay.
I’d the contents of the lib folder in a zip file
and then use gestalt to download the zip. from then on they are
available

That’s a good idea but it enforces the user to use Gestalt.
Which brings up another question - are we willing to “standardize”
Gestalt
by making it the best practice for using DLR languages in Silverlight?

OK I zipped the libs folder and added it to the page as .
When I try to require the assemblies, the files are not found.
I tried to make the case simpler and zipped a simple rb file to a zip
and
included it in the page as well:
I tried:
require “TestClass.rb”
require “TestClass”
require ‘test.zip/TestClass.rb’
require ‘test.zip/TestClass’
None of these worked.
By the way, I see that Chiron loads the zip files…
What am I doing wrong?

for assemblies you need to add an appmanifest I think

It doesn’t work for Ruby files as well as assemblies (which are placed
within a ZIP file)…

I thought that already happened (dlr-slvx requirement etc)

if you put a app\myfile.rb in the zip file
you should be able to do require ‘app/myfile’

Wow, a lot of questions to answer here; let me know if I missed one …

Depends on whether your using the Chiron to generate a XAP file, or your
using dlr.js and embedding Ruby code in the HTML page with script-tags.
Chiron to generate the XAP:
Just copy the necessary Ruby stdlib files into your XAP file directory.
If you just want to reference an entire directory, you can use the
“-path” Chiron.exe option.
Script-tags:
See the IronPython docs on this:
http://ironpython.net/browser/docs.html#zip-files. Basically you must
have a script-tag like this: . Then you can reference the “lib” directory in
your scripts, including adding it to the path: .
You can also just list out each Ruby file used:
foo.rb
require ‘bar’
I hope this shows that script-tags just download the script, and add it
to the “virtual file-system” that the DLR-languages see. The “defer”
attribute causes the script to not be run; it will be run when a script
requires it.
None of these worked.
By the way, I see that Chiron loads the zip files…
What am I doing wrong?
Change the mime-type to application/x-zip-compressed and try requiring
“test/TestClass” … that will work. We should also allow
application/zip as the mime-type:
http://ironpython.codeplex.com/WorkItem/View.aspx?WorkItemId=26676. Keep
in mind that Silverlight can only read archived files created with a
deflate ZIP algorithm; but using Chiron to create the zip file will
ensure it works … something like “Chiron.exe /d:lib /x:lib.zip”.
for assemblies you need to add an appmanifest I think
Actually, all the AppManifest.xaml does it load the assemblies for you;
you can use “require” or “load_assembly” to accomplish the same thing,
so I advise against touching the AppManifest.xaml, unless your XAML has
dependencies on an assembly.
Keep in mind there is no way to have an “assembly script-tag” … you
must put the assembly in a ZIP file.
if you put a app\myfile.rb in the zip file, you should be able to do require ‘app/myfile’
Close … you have to use the file filename in the require call, or add
the zip file name to the path (see example above). Today this only works
when you use the zip file name without it’s extension, but that’s a bug
IMO: http://ironpython.codeplex.com/WorkItem/View.aspx?WorkItemId=26677.

Well on its way; the http://ironpython.net/browser/ page only has
documentation for the “Gestalt”-way, though the Chiron/XAP model will
also be documented. Fun fact: while the first version of Gestalt (0.5)
was made completely independently by the visitmix.com/labs team, the 1.0
release was completely rewritten and merged into
Microsoft.Scripting.Silverlight.dll. In fact, the current source code on
gestalt.codeplex.com is only the code from 0.5; the latest source code
for Microsoft.Scripting.Silverlight is in IronRuby’s GitHub and
IronPython’s CodePlex source repos.
Keep in mind the previous Chiron/XAP file model isn’t going away;
Gestalt takes [too-must] advantage of how Silverlight expects apps to be
structured, so there are some limitations to it. The glaring limitation
is you can’t run gestalt apps out-of-browser; HTML doesn’t work there
… there might be a way around this by using Silverlight’s ability to
host HTML content IN a Silverlight control, but that hasn’t been tested
yet. So the Chiron/XAP model will continue to be supported, but I don’t
advise using it unless you need to run out-of-browser. You can also
combine the two; the IronRuby tutorial uses the Chiron/XAP model for the
app, but the Gestalt-way to enable tests running in the browser.

I think the Chiron model is better for different scenarios. You
mentioned
OOB, but also if IronRuby (or other Dynamic Languages) are used as part
of a
statically compiled app where XAPs and assemblies are distributed in the
typical SL way. Not sure how we would do it with Gestal as I’ve seen
that it
relies on the Script tags. Is there a way of doing that
programmatically?

It doesn’t work for me.

When using IronRuby in a Silverlight app where the main language is C#
or VB, then you wouldn’t be using Chiron at all. You’d add the script
files to your Silverlight project, and use the DLR hosting API to run
them.
You could still use script-tags in this scenario as well; you’d need to
look at the source for
Microsoft.Scripting.Silverlight.DynamicApplication and call into its
initialization logic from your app.

Jimmy,
I was thinking more of an scenario where one of the teams in a project
do
one of the modules in IronRuby that would be downloaded on demand.
I guess one option would be for them to create a C# project and package
their IR code in there. That project could also have the hosting and
bootstrapping logic to hooked that module into the rest of the app.
That’s
certainly the simplest way. I was thinking to use Chiron to download the
XAP
and let a “ModuleLoader” worry about how hosting it. Now that I
mentioned it
I guess we could do something similar with Gestalt.
I will play a bit with both options on the weekend.
Miguel
