Auto-Generating Visual Editors for Formal Logics with Blockly

Formal logics are central to the specification and verification of computational systems, yet their adoption outside highly specialised domains is hindered by steep learning curves and error-prone textual notations. Making these notations more approachable is particularly important in education and in settings where non-expert stakeholders need to engage with formal reasoning. We present a framework that automatically generates block-based visual editors for formal logics using the Blockly library. From a structured JSON specification of syntax and composition rules, our tool produces browser-based editors in which formulas are constructed by combining graphical blocks rather than writing code. This approach lowers syntactic barriers for learners and non-experts, while allowing experts to define new logics without manual interface design. Although integration with verification backends is planned, the tool already provides a reusable foundation for accessible and customisable logic editors.
