Announcing Graphrex, a tool that analyzes a Java regular expression and creates a diagram with a visual representation of the regex's structure and flow. Graphrex is a free plugin for the Eclipse IDE. Graphrex promotes the understanding, documentation and debugging of regular expressions.
Graphrex includes (1) a new resource type that Eclipse uses to store the diagram so that it can be saved and re-opened; (2) an editing area where the regular expression can be entered as text, with instant feedback on syntax errors; (3) the diagram, which has interactive features to allow you to select and zoom, or inspect the contents of character sets; (4) enhancements to the Eclipse UI to help you to manipulate your Graphrex diagram; and (5) a structured view that of the regular expression that is linked to the diagram, so that selecting something in the diagram selects it in the view, and vice versa.
