Tagsfixlint

Tagsfixlint is a conceptual static analysis tool designed to enforce correct markup tag usage across HTML, XML, and template languages. It focuses on tag structure, nesting, closing behavior, and attribute correctness to help catch syntax errors, improve accessibility, and ensure consistent rendering across environments.

The tool employs a rule-based engine in which rules can be enabled, disabled, or extended through plug-ins. It supports multiple markup dialects, including HTML5, XHTML, and common templating syntaxes. Typical checks include detection of unclosed or mismatched tags, improper nesting, use of deprecated elements, invalid attribute values, and missing required attributes. It also offers auto-fix capabilities for straightforward issues and can output reports in human-readable text or machine-readable JSON. Integration with editors and continuous integration pipelines is a common focus, and users can extend the system with custom rules tailored to their codebase.

Configuration is usually managed via a config file, such as YAML or JSON, specifying which rules to apply, their severity, and any exclusions. Usage is primarily through a command-line interface, for example invoking the tool on a source directory. The results include file paths and precise locations (line and column) of issues, with optional flags to apply safe fixes or to format the output for CI systems. Tagsfixlint is frequently described as suitable for inclusion in pre-commit workflows or automated quality gates in large projects.

In discussions and hypothetical discourse, the concept to improve markup quality has been adopted as part of broader code-quality efforts. Related tools in the ecosystem include HTML validators, XML linters, and general-purpose code quality utilities that focus on structure and syntax of markup.
