Calling ruby scripts from C#

Ruby IronRuby
#1

Dear users,

I want to build a testscript scheduler / executer in C# that runs
several Ruby scripts in sequence.

For this I use IronRuby with the following constuction:

ScriptRuntime runtime = Ruby.CreateRuntime();
ScriptEngine engine = runtime.GetEngine(“rb”);

loop through scripts:
engine.ExecuteFile(“script.rb”);

This works fine for basic scripts. However some scripts have class
definition that inherite from a base class.
When such a script (class < baseclass) is passed in:
engine.ExecuteFile(“script.rb”);

The following exception is thrown:
Microsoft.Dynamic
uninitialized constant Object::BaseClass

I can not find a solution for this problem, so any suggestion is
welcome. If I need an other approuch, do hesitate to say so. Still
learning about Ruby integration in .NET

Thanks in advance

#2

you have to require the other files it uses too in the same engine.
or you can add the paths to where the scripts can be found to the
$LOAD_PATHS ($:) variable.

require a file:
http://github.com/casualjim/ironrubymvc/blob/master/IronRubyMvc/Core/RubyEngine.cs#L279

add load paths
http://github.com/casualjim/ironrubymvc/blob/master/IronRubyMvc/Core/RubyEngine.cs#L346

Check out the code in this article:
http://www.highoncoding.com/Articles/573_First_Look_at_the_IronRuby.aspx

Thanks! The require a file (containing the base) option works.

But adding the path to the file containing the base class does not. Here
C# reports an error that the file can not be found. Don’t what’s wrong
here, but for know the require a file option will do the trick.

#5

root |_ lib
|_ great_class.rb
|_ test
|_ test_great_class.rb

let’s say I add root to my load path
then I can reach the files in lib with require ‘lib/great_class’

or in test_great_class.rb you can do
require File.dirname(FILE) + “/…/lib/great_class”

you are free to add the extension in case you’re using require.

In our application, we also found we found ‘load’ useful in some
circumstances to force reloading of script files, since ‘require’ will
not
reload files it knows it’s already loaded.

If the base class is defined in file “foo.rb” and used in file “bar.rb”
this should also work:

engine.ExecuteFile(“foo.rb”);
engine.ExecuteFile(“bar.rb”);

Example:

C:\Temp>type foo.rb
class C
end
C:\Temp>type bar.rb
class D < C
end
p D.ancestors

C:\Temp>rbd

Agreed. We found if we changed the definition of class C, unless we did
something like ‘load’, it would continue to use the old definition from
the first load.

Kernel#load is very similar to ExecuteFile, so you can use either for
bringing the definition up to date.

Apologies if my earlier answer was rude. I wasn’t trying to be rude, and
looking at it I realize it could be taken as such. I know I appreciate
hearing that people are using IronRuby on real projects, not just as a
novelty language ☺

In our application, we also found we found ‘load’ useful in some
circumstances to force reloading of script files, since ‘require’ will
not reload files it knows it’s already loaded.

Re: [Ironruby-core] calling ruby scripts from C#

root
|_ lib
|_ great_class.rb
|_ test
|_ test_great_class.rb

let’s say I add root to my load path
then I can reach the files in lib with require ‘lib/great_class’

or in test_great_class.rb you can do
require File.dirname(FILE) + “/…/lib/great_class”

you are free to add the extension in case you’re using require.

Indeed. We came to Ruby from C#, so it wasn’t immediately obvious to us.

Thanks!

Agreed. We found if we changed the definition of class C, unless we did
something like ‘load’, it would continue to use the old definition from
the first load.

Re: [Ironruby-core] calling ruby scripts from C#

If the base class is defined in file “foo.rb” and used in file “bar.rb”
this should also work:

engine.ExecuteFile(“foo.rb”);
engine.ExecuteFile(“bar.rb”);

Example:

C:\Temp>type foo.rb
class C
end
C:\Temp>type bar.rb
class D < C
end
p D.ancestors

C:\Temp>rbd

No worries, I didn’t read your comment as rude. I fully realize the
error
of my ways in not embracing Ruby earlier in my career. :wink:

It’s just an interesting thing to keep in mind with projects like
IronRuby, that people come to it with different backgrounds. It will be
interesting to see what sort of orientation documents are produced for
those coming to IronRuby from a .NET (C#/VB.NET) background. I foresee
articles like these from the days when C# was young:

C++ -> C#: What You Need to Know to Move from C++ to C#
http://msdn.microsoft.com/en-us/magazine/cc301520.aspx

C# From a Java Developer’s Perspective

Re: [Ironruby-core] calling ruby scripts from C#

Apologies if my earlier answer was rude. I wasn’t trying to be rude, and
looking at it I realize it could be taken as such. I know I appreciate
hearing that people are using IronRuby on real projects, not just as a
novelty language J

Thanks,

Thanks for all the information. Being new to IronRuby, I will need all
the info I can get and will most probably be back with futher questions.
