18.9. The Rule Editor

The rule editor is where rule managers and developers are modified. The rule editor follows the pattern of a normal text editor in Eclipse. It provides pop-up content assistance. You can invoke pop-up content assistance by pressing Ctrl+Space.

The rule editor works on files that have a .drl (or .rule) extension. Usually these contain related rules, but it would also be possible to have rules in individual files, grouped by being in the same package namespace. These DRL files are plain text files.
