At first, I installed CYWIN on his Windows 7 (64bit) box because CYGWIN's terminal window shells, e.g., RXVT terminal, display the text using color codes, unlike the stock MS Windows terminal/console application.
Here are some things we learned:
- RBENV does not install easily under CYGWIN
- It's better to go with the stock Ruby install from CYGWIN
- Windows terminal emulators run a little faster than CYGWIN terminal applications
So, we ended up installing CONSOLE from http://sourceforge.net/projects/console/
Console is a Windows console window enhancement. Console features include: multiple tabs, text editor-like text selection, different background types, alpha and color-key transparency, configurable font, different window styles
Now, he's can read his colored Cucumber test results in the Console and he has an install of CGWIN, which he can use for nice unix'y command line fu.
