Hello,

I have a problem using autotest on Windows XP. When launching  
‘autotest -rails’, autotest runs the following command :

C:\Program Files\ruby\bin\ruby -I.;lib;test -rtest/unit -e "%w […]  
| unit\_diff -u

As you can see, I installed ruby in “Progam Files” directory, which  
now represents a problem when running autotest. Indeed, I get the  
following error message :

‘C:\Program’ is not a valid command.

simply because of the space between “Program” and “Files”. I didn’t  
find anything about this problem on google, I guess because the  
default ruby directory is “C:\ruby” and I may be the only one who  
wanted to change that.

Any chance I can fix that myself ?

Thanks a lot,

Nicolas R.

Dear Nicolas,

unfortunately, I haven’t got Windows XP handy right now to test it,  
but I think if you enclose C:\Program Files\ruby\bin\ruby  
in quotes, as suggested here

[http://www.tnk-bootblock.co.uk/forum/viewtopic.php?t=612](http://www.tnk-bootblock.co.uk/forum/viewtopic.php?t=612),

you should be fine. So you’ll have to correct that in the program  
that creates the string C:\Program Files\ruby\bin\ruby  
in the first place.

Best regards,

Axel

Sorry, I hit send before I was done. Just wrapping the ruby method in  
quotes alone didn’t work for me, but putting call in front of it seems  
to work.

Hope it helps.

Try this in your .autotest file

Autotest.send(:alias\_method, :real\_ruby, :ruby)  
Autotest.send(:define\_method, :ruby) do |\*args|  
return %[call “#{real\_ruby}”]  
end
