RegexFlow

RegexFlow is a unique, visual regular expression builder that allows developers to construct complex patterns using an intuitive, node-based flowchart interface. It demystifies regex syntax by transforming it into a series of connectable logical blocks. How it works step-by-step: Add Regex Nodes: The user adds logical components of a regex pattern—such as a "Literal" character, a "Character Set," a "Quantifier," or a "Group"—by dragging them from the sidebar onto the canvas or by simply clicking on them. Arrange the Flow: The user arranges the nodes horizontally on the canvas. The application automatically interprets the left-to-right order as the sequence of the regex pattern. Configure Each Node: The user fills in the value for each node (e.g., entering "abc" in a Literal node, "a-z" in a Character Set node, or choosing "+" from a Quantifier's dropdown). See Instant Results: As nodes are added, moved, or edited, the application performs two actions in real-time: It generates the complete regular expression string at the bottom of the screen. It highlights all matches within a "Live Tester" text area, providing immediate feedback on how the pattern behaves. Visualize the Structure: The nodes are automatically connected with lines, providing a clear, visual representation of how each part of the regex links to the next, making it easy to understand the overall structure.
