Ironruby core - Oct 2009 - Newbie questions regarding IronRuby in Silverlight...

Hi Guys,

How do we, for example, use BigDecimal in IronRuby within a Silverlight
application?  When we just require ''bigdecimal'', we get an
error saying
that file can''t be found.  Do we have to add that and other ruby
standard library files to our application and if so, where do we put
them?

Note that we are actually developing a standard (non-dynamic) C#
Silverlight application (and hence are not using Chiron) and wish merely
to execute ruby scripts client-side at various times.  We would like
these scripts to be split into different files, for obvious reasons.  We
envisage that certain files (i.e. standard library and other non
changing code) may well be bound into the xap file somehow and other
files may well be dynamically obtained from the back-end.

So far, we''ve been able to execute ruby files deployed as "Build
Action:
Resource" in VS2008 but, we have not, as yet, been able to get one file
to require another in a similar manner to the Chiron demos in IronRuby
0.9.1. (i.e. app.rb requires Silverlight.rb).

Any help would be greatly appreciated,

Thanks,

Zoltan.

But that will include all the files and gems you have installed on your
machine for ironruby.
It might be a better idea to copy the ruby files you need into a folder in
your project.
You can use them as an embedded resource and then execute their code in
order to require them
ExecuteScript does that for you.

If you want to use the plain ruby require syntax then you can include them
in the root folder of what gets included in the xap. If your Silverlight
application is a DynamicApplication then you have the necessary PAL loaded
and you can use plain require statements

Many thanks to all of your input.  Much appreciated!
I''ll try your suggestions over the next few days and let you know the 
results.

Thanks again,

Once again thanks, we were able to get things working.  Please note that 
we have offline requirements that require us to deploy the portions of 
the ruby standard library that we require, within our Silverlight 
application.

My only other question is why does IronRuby ship with what appears to be 
two versions of the Ruby standard library?  There appears to be a 
standard implementation (i.e. \lib\ruby\1.8 for IronRuby 0.9.1) that 
uses ruby scripts and there also appears to be an implementation that 
calls into the CLR (i.e. \lib\IronRuby) in order to do its stuf.  Do we 
have a choice of which to use or do we need to deploy both?

Many thanks for your help.

Zoltan.

I''ve been pondering the exact same thing - it is a touch confusing.

There are not two copies, one is ruby stdlib, and one is IronRuby''s  
own lib. The ruby stdlib contains pieces implemented in ruby, as well  
as C. In IronRuby we ported all the C stuff to C# (that''s what  
IronRuby.Libraries.dll is), and redistribute the ruby code. So both  
directories are all part of the standard library.

For Silverlight, I would suggest you only deploy the files that you  
use; the entire stdlib is fairly large.

Is anyone aware of a tool that can recursively detect (and possibly
extract) ruby dependencies given a top level .rb, or set of .rb files? I
could see it being a tedious process to discover manually what
components of the standard library were used by any given application.

It is not possible to completely and reliably automate such task in general. You
could run your application and see what files are being required. You can
monkey-patch Kernel#require and load so that they log the files being required.
However you would need to exercise all code paths that might possibly load a
file to get the full list.

If you want to give it a try anyways you can also pass -ET LOAD_COMPILED command
line options to ir.exe to see what files are being loaded. For example:

Well, if you have good test coverage for your ruby code, that should be
doable :) Probably monkey patching and good tests is the way to go then.
In your journeys through the Ruby standard libraries, have you noticed
that they tend to require/load dependencies dynamically (i.e. based on
magic strings a static automation tool could not follow) fairly
frequently? Or is it rather rare? Also, would it be feasible to host the
standard libraries on the web and rig up the hosting environment to fall
back to a web server if the libraries being dynamically loaded weren''t
properly deployed with the app?
