Ironruby core - Jun 2009 - Where is open-uri and why it does not work?

I have been trying this for weeks now and still no answer. The open-uri
is messed up in IronRuby. Why does it always keep opening a file and not
the URL?

Why stringio is not present in the same folder as ''open-uri''?
-- 
Posted via http://www.ruby-forum.com/.

StringIO is written in C#, so it is part of IronRuby.Libraries.dll. This is
because Ruby''s StringIO has C extensions.

What?????

I am talking about ''open-uri'' and when I run this:

ir myapp.rb

It throws the exception that it is missing uri and stringio. Why all the 
libraries are not put in the same folder why are they distributed in 
many different folders?

And there is a file called ''stringio.rb''

The libraries required by open-uri to function properly are spread up in 
two different folders:

paths.Add(@"C:\ironruby\ironruby\Merlin\Main\Languages\Ruby\Libs");
           
paths.Add(@"C:\ironruby\ironruby\Merlin\External.LCA_RESTRICTED\Languages\Ruby\redist-libs\ruby\1.8");


WHY?

The file stringio.rb (the correct one) has the following in it:

load_assembly ''IronRuby.Libraries'',
''IronRuby.StandardLibrary.StringIO''

There are two library paths in IronRuby. One is the redistribution of most of
the Ruby Standard library. This is the 
C:\ironruby\ironruby\Merlin\External.LCA_RESTRICTED\Languages\Ruby\redist-libs\ruby\1.8
folder. The other is IronRuby specific files to load C-based standard libraries
(such as stringio.rb) and stub files to make .NET specific assemblies easier to
load (such as System.Windows.Forms.rb).

For me, the following works from the IronRuby console. Can you send me the
output of it when you try to run it from ir.exe?

Thanks for the detailed explanation!

The steps that you have provided worked!

But the main question is that if I am using my project from a different 
directory like C:\RubyProject\ and I am also running IR.exe from 
C:\RubyProject then how will it find open-uri.

It always says ''not able to locate open-uri'' file. If I
manually add
''open-uri'' to c:\rubyproject\libs then it complains not able
to find
''uri''

Does it work if you copy open-uri.rb, uri.rb and the uri directory to
C:\rubyproject\libs?

Nope it does not work:

Here is the code:

require ''libs/System.Windows.Forms''
require ''libs/System.Drawing''
require ''libs/open-uri''

The libs folder contains uri.rb which is taken from

C:\ironruby\ironruby\Merlin\External.LCA_RESTRICTED\Languages\Ruby\ruby-1.8.6p287\lib\ruby\1.8

folder.

And here is the error:

C:\IronRubyProjects\IronRubyTaskListApplication>ir rss_reader_form.rb
:0:in `require'': no such file to load -- uri (LoadError)
        from ./libs/open-uri.rb:1
        from rss_reader_form.rb:3
        from :0:in `require''

What does puts $: output in that situation? I''m wondering why you have
"require ''libs/open-uri''" instead of "require
''open-uri''"

It is outputing the following:

>>> puts $:
C:/WINDOWS/system32

Posted via http://www.ruby-forum.com/.

Is this one of our releases? Or is it a build from the git sources? In both
cases you should have an ir.exe.config that sets both the libs folder and the
redist-libs folder into your load path.  Any idea why yours doesn''t?

This is downloaded from Git!

I have the ir.exe.config file with the following path setup:

 <options>
      <set language="Ruby" option="LibraryPaths" 
value="..\..\Languages\Ruby\libs\;..\..\..\External.LCA_RESTRICTED\Languages\Ruby\redist-libs\ruby\site_ruby\1.8\;..\..\..\External.LCA_RESTRICTED\Languages\Ruby\redist-libs\ruby\1.8\"
/>
    </options>

The location of this file is:

C:\ironruby\ironruby\Merlin\Main\bin\Debug

My project location is C:\IronRubyProjects\IronRubyTaskListApplication.

I am running the IR.EXX from 
C:\IronRubyProjects\IronRubyTaskListApplication and then it complains 
about the open-uri file. I put the open-uri file in the libs folder then 
is complains about uri file. I put the uri file and uri folder in the 
libs folder but it still complains about the uri file.

I have even tried running ir.exe from my projects folder:

Can you run c:\ironruby\ironruby\Merlin\Main\bin\debug\ir.exe
C:\IronRubyProjects\IronRubyTasksApplication\foo.rb (where foo is the startup
file for your program)?

I should also mention one thing which is that I placed my ir.exe and 
some other files that are required by ir.exe in System32 folder so that 
I can access it from anywhere in the directory.

A better way to do that, in this case, is to just add
c:\ironruby\ironruby\Merlin\Main\bin\debug to your %PATH%

No I cannot run it because it require Windows.Forms and Windows.Drawing 
modules. If I add those modules then it will work:



C:\ironruby\ironruby\Merlin\Main\bin\Debug>ir.exe 
C:\IronRubyProjects\IronRubyTa
skListApplication\main_form.rb
C:\ironruby\ironruby\Merlin\Main\Languages\Ruby\Libraries.LCA_RESTRICTED\Builtin
s\KernelOps.cs:423:in `require'': no such file to load -- 
libs/System.Windows.For
ms (LoadError)
        from 
C:/IronRubyProjects/IronRubyTaskListApplication/main_form.rb:2
-- 
Posted via http://www.ruby-forum.com/.

How do I do that?
-- 
Posted via http://www.ruby-forum.com/.

Should I also remove ir.exe from System32?
-- 
Posted via http://www.ruby-forum.com/.

I have added the path to System Variables. The name of RUBYLIBS and the 
value is c:\ironruby\ironruby\Merlin\Main\bin\debug.

Here is the code:

require ''libs/System.Windows.Forms''
require ''libs/System.Drawing''
require ''open-uri''

And still giving the same issues:



C:\IronRubyProjects\IronRubyTaskListApplication>ir rss_reader_form.rb

C:\IronRubyProjects\IronRubyTaskListApplication>ir rss_reader_form.rb
:0:in `require'': no such file to load -- open-uri (LoadError)
        from rss_reader_form.rb:3
-- 
Posted via http://www.ruby-forum.com/.

I have set up the PATH variable in System Variables to 
C:\ironruby\ironruby\Merlin\Main\bin\Debug

But now windows command prompt is not picking up the ir.exe file!
-- 
Posted via http://www.ruby-forum.com/.

Remove the RUBYLIBS variable, and then change require
''libs/System.Windows.Forms'' to require
''System.Windows.Form''. Do the same for System.Drawing, then
let me know how it goes. You shouldn''t need to set any Ruby environment
variables, since ir.exe.config should set everything up for you right now.

Finally I got it!

I closed the command prompt and ran it again and now everything is 
working. Even the open-uri started working.

Thanks for all your help!

The PATH was a good solution to go :)
