I have two problems with my Ruby for Windows (1.8.4): 1. When I double-click on a file with .rb extention a DOS-like window appears and dissapears immediately. I am not able to see results. 2. The Windows command (which should work as it’s UNIX parent) echo ‘puts “Hello”’ | ruby (the command is borrowed from “Programming Ruby” 2nd edition p.318) # does not show any results: C:\Documents and Settings\Admin\>echo ‘puts “Hello”’ | ruby # C:\Documents and Settings\Admin\> Sure, it works with Linux. How to tune my Windows XT Pro to be more Ruby friendly? Thank you Henry ---

> C:\Documents and Settings\Admin\>echo ‘puts “Hello”’ | ruby > > C:\Documents and Settings\Admin\> Look at the output of the echo command: C:\>echo ‘puts “Hello”’ ‘puts “Hello”’ The windows shell includes the single-quote whaere as bash does not. try: C:\>echo puts “Hello” | ruby Hello C:\> As for the problem with the DOS box. Adding a requireing input at the end of the program is one (poor) solution, as is using a cmd shell. I hope someone has a better one J.F. Miller ---

Try: > echo puts “aa” | ruby > aa > ruby -e ‘puts “aa”’ > aa ---

Then the window will not go away, and you’ll be able to see the result. I suppose you did it that way in the next question, so I’m afraid I’m stating the obvious 😉 If you want to see the results when doubleclicked the file, add something that will pause your program at the end (e.g. gets, sleep) or write your result to a file. And in case you’d not want to see even the DOS window, rename your file to .rbw 😉 ---

Just write a little batch file: @echo off ruby %1 pause Save it in your Ruby bin directory (I called mine rdos.bat), and associate rb files with it. HTH. Cheers, Cory ---

In explorer, if you go to folder options, and click advanced for the .rb extension, you will see that it uses the following to open a .rb file: “c:\ruby\bin\ruby.exe” “%1” %\* You can get the windows to stick around if you change that to: cmd.exe /K “c:\ruby\bin\ruby.exe %1 %\*” I wouldn’t recommend it tho, since you won’t be able to accept files with spaces and justhaving the windows stick around is nasty. Better run your script from a cmd instance. > Thank you > Henry HTH ---
