QML Checker

Purpose-built for Qt/QML developers and code reviewers, the QML Checker analyzes QML sources to surface syntax errors, undefined IDs, and binding issues. It operates without executing the application, providing immediate diagnostics that guide fixes. The tool models a formal QML grammar, builds a lightweight symbol table, and applies targeted checks to reveal structural problems early.\n\nConceptually, it treats QML as a declarative graph of components, properties, and bindings; by resolving identifiers and cross-references, it detects orphan components, invalid imports, and mismatched property types. The resulting output prioritizes high-severity issues and offers actionable suggestions to improve code quality. Its modular checks support common Qt Quick patterns, enabling reliable validation across projects.\n\nBenefits are clear for teams integrating this into CI or IDE workflows: faster feedback loops, reduced manual debugging, and higher confidence in code before runtime. Unique value lies in its combination of grammar-based parsing with pragmatic diagnostics and optional quick-fix recommendations. Typical use cases include validating new QML files, auditing third-party components, and enforcing project conventions in large Qt Quick deployments.\n\nCore features include syntax validation, undefined ID detection, binding analysis, and import verification as mandatory checks; optional enhancements cover version compatibility, duplicate IDs, and automated fix suggestions. The tool emits diagnostics with precise locations to streamline remediation.
