.RB File Extension

An RB file is a software program written in Ruby, an object-oriented scripting language. Ruby is designed to be simple, efficient, and easy to read. RB files can be edited with a text editor and run using Ruby.

Ruby is available in several different versions, or "gems," including Ruby on Rails, Mongrel, and Capistrano.

NOTE: Google Sketchup 4 uses Ruby files to automate repetitive tasks.

Software development project created by Xojo, an IDE that uses Realbasic, an advanced version of the BASIC programming language; used for developing cross-platform software for Mac, Windows, and Linux from a single set of source code.

RB files were used by older versions of Real Studio. Newer versions use the .RBP extension.

NOTE: REAL Software Real Studio became Xojo, Inc. Xojo in 2013.

An RB file may also be a configuration file used by Rosebud, a Windows CE and Windows Mobile application that allowed users to control devices via SMS. It contains XML that defines a user's Rosebud commands. Rosebud and RB files were used on Pocket PC devices.

Because RB files are XML files, you can open and edit them in any text editor, including:

• Microsoft Notepad (Windows)
• Apple TextEdit (Mac)
• Github Atom (cross-platform)

Then, provided you still have access to Rosebud, you can use your RB file as a Rosebud configuration file by placing it in the directory specified in Rosebud's CfgPath registry setting.
