eslint-merge-processors enhances ESLint by enabling the combination of multiple processors for a single file type. This allows developers to utilize various processors (e.g., for extracting code from Markdown or HTML) and then process the extracted code with JavaScript-specific ESLint rules. Effectively chains processors, executing them sequentially to analyze complex file structures, providing richer linting capabilities and improved code quality analysis across diverse file formats. Simplifies configuring multi-stage processing.
