The current beta version of Sapphire in Steel provides an editing environment for Ruby programs and comes with syntax coloring and the ability to run console applications with one keystroke. It also includes debugger support for breakpoints, watch variables, step-into/over, autos, and locals. Along with other features such as wizards for setting up MySQL database connections, Sapphire inevitably draws comparisons to the Eclipse-based RadRails. Will the familiarity of the Sapphire environment in VisualStudio appeal more to .NET developers than the free RadRails?
Sapphire in Steel does not include a Ruby runtime for Windows, available via the one-click installer.
