Sierra is a browser-based interactive development environment (IDE) for Epilog. It allows users to view and edit datasets and rulesets. It provides a variety of tools for querying and modifying datasets and rulesets. As changes are made, it automatically updates visible datasets in spreadsheet-like fashion in accordance with the user's rules. It also provides tools for analyzing datasets and rulesets, tools for tracing program execution, and tools for saving and loading files.
The command bar across the top provides access to menus concerning files, tools, and worksheets. Click here for an introduction to the system and it capabilities.
