EditorConfig Validator

The EditorConfig Validator analyzes EditorConfig files to ensure consistent formatting rules across a codebase. It parses INI-like syntax, validates known properties such as indent_style, indent_size, end_of_line, charset, insert_final_newline, and trim_trailing_whitespace, and reports violations with exact file, line, and column locations. The tool supports per-directory and root-level rules, enabling detection of conflicts across multiple files or patterns. Conceptually, it compares actual values against project-wide conventions and highlights mismatches that can affect multi-language projects and cross-platform teams. Unique value lies in its ability to produce CI-ready diagnostics and batch-check capabilities, allowing teams to enforce standards automatically rather than relying on manual reviews. Use cases include ensuring all files use spaces with a specific indent_size, aligning end_of_line settings for Windows and Unix environments, and catching missing rules that could lead to inconsistent code formatting. Core features include a robust parser, per-file diagnostics, cross-file comparison, and exportable outputs for automation. Beneficiaries include repository maintainers, CI/CD engineers, and developers who participate in multi-repo or polyglot projects. The tool provides a deterministic, granular view of where rules diverge and what fixes to apply, enabling bulk remediation and repeatable validation across builds.
