I am trying to get a Ruby file to run through C#. I was reading through
"Ruby Unleashed" (book), and it appears to be easy. However, I keep
getting an error on a very simple test. The text of my programs are:
C#:
using System;
using Microsoft.Scripting.Hosting;
using IronRuby;
class Run_Ruby
{
static void Main()
{
ScriptEngine engine = IronRuby.Ruby.CreateEngine();
engine.ExecuteFile("C:/Test_Files/hello.rb");
}
}
-------------
hello.rb:
puts ''hello''
When I run the program I get:
"MissingMethodException was unhandled"
"undefined method `???puts'' for main:Object"
I am a novice to C#, but this should be hard. What am I doing wrong?

What version of IronRuby do you use?
The file has UTF8 BOM at the beginning and IronRuby 1.0 doesn''t support
that (MRI 1.8.6 doesn''t either). IronRuby 1.1.1 should work fine.

before i think about it too much, it seems you have some unicodish chars in the file?

confirmed. you probably created the file inside VS, or other UTF happy editor. if you insist you might want to try the encoding pragma, but i''m not sure of its support # coding: utf-8 puts ''hello'' On Tue, Nov 2, 2010 at 9:41 PM, Dotan N. <dipidi at gmail.com> wrote:> before i think about it too much, it seems you have some unicodish chars in > the file? > > > On Tue, Nov 2, 2010 at 8:07 PM, Timothy Barnes <lists at ruby-forum.com>wrote: > >> I am trying to get a Ruby file to run through C#.

Thanks for the replies. I recreated hello.rb in Scite and the program worked. I have read about UTF8 encoding and ruby, but had not ran into it before, and I didn''t not know what the symbols in front of the hello.rb text meant (see VS error message). So thanks for the help. Tomas: I was using IronRuby 1.0.0.0 but had just downloaded IronRuby 1.1.1. However, I originally created the file in SharpDevelop and have been creating IronRuby programs in SharpDevelop with no issue (running in SD Debug), until I tried to call this ruby file from C#. So I still don''t quite understand why ruby works one way and not the other, but that seems to be a SharpDevelop issue/setting. I am pretty sure SharpDevelop is running IronRuby 1.0.0.0. After I couldn''t get it to work I tried it again in Visual Studio which I assume also called IronRuby 1.0.0.0. since I still had that version installed and my files associated with that version. Last, Now that IronRuby supports the UTF8 encoding, should my files be encoded that way? Or now does it just not matter which encoding I use? and does C# have to be encoded UTF8? -- Posted via http://www.ruby-forum.com/.
this is not an ''issue'' with either editors. it is simply a matter of encoding. As i previously noted, you''ve created the file in visual studio, which adds: http://en.wikipedia.org/wiki/Byte_order_mark please find the time to read this http://www.joelonsoftware.com/articles/Unicode.html On Wed, Nov 3, 2010 at 3:19 PM, Timothy Barnes <lists at ruby-forum.com> wrote:> Thanks for the replies. > > I recreated hello.rb in Scite and the program worked.

Dotan, Thanks for the links. I have been looking for a place to explain encoding well for awhile. I am a self-trained programmer and sometimes it is hard to find good info to increase my knowledge base. Thanks for the help. -- Posted via http://www.ruby-forum.com/.
Files don''t need to be encoded in UTF8, you can chose any encoding supported on your system. IronRuby 1.1.1 supports BOMs and also Ruby specific #encoding directives. I would suggest always using UTF8. Personally I consider any non-Unicode based encoding obsolete and frankly don''t understand why Ruby went the way they did with all that complexity around encodings. It just makes it slower and cumbersome to use.

Tomas, I appreciate the suggestion. The reason I was trying to do this was to create and .exe file that I can distribute to other co-workers without them having to understand what ruby is. The only other answer I can''t find through internet searches is whether on not I can suppress the console window while running a window application through IronRuby. (similar to the using a .rbw file) It appears that this is not possible. Is that correct? Timothy -- Posted via http://www.ruby-forum.com/.

I mean you can indeed write a Windows app in C# or VB that hosts IronRuby and that doesn''t need the console window (you can redirect standard output to a stream if you would like to display it in some window). The thing that''s missing from IronRuby is irw.exe file that would do that for you (we have a similar one for Python).

It''s already there - build Solutions\Ruby.sln from GIT repo (https://github.com/ironruby/ironruby/archives/master): msbuild Solutions.Ruby.sln /p:Configuration=Release This produces binaries to bin\Release directory. You''ll need to take all IronRuby binaries (not just irw.exe). Of if you''d rather make an installer (IronRuby.msi) go to Msi directory and run msbuild Installer.proj /p:Configuration=Release This produces the .msi also into bin\Release.

There are some issues with how library load paths are set up today (gem_prelude load error), I''m working on a fix. I might finish it this weekend.

No, you don''t need to build anything before you build the installer. What are the errors? Do you have VS SDK 2010 installed? You need to have that so that the VS integration builds.
