ascii-diagram-validator

ASCII diagram validation detects misaligned verticals, corners, and junctions in box-drawing diagrams within Markdown and documentation files. Run the validator against your files to receive compiler-like reports with file, line, column, and severity details, plus suggested fixes to restore alignment.

Yes, the validator supports multi-file and directory-level scanning. Process entire architecture diagram collections, README files, and code comments in one pass to identify alignment issues across your project systematically.

The validator detects vertical misalignment, broken corner and junction connectivity, improper line termination, and unclosed boxes. It applies structured detection rules and outputs actionable coordinates and fix suggestions for each issue found.

The validator outputs compiler-like issue reports that include optional fix suggestions alongside file location and severity. Review the suggested corrections to restore proper alignment without manual recalculation of box-drawing characters.

Use validation when maintaining architecture diagrams in documentation, README files, and code comments to catch misalignments early. It's essential for projects with multiple contributors or complex ASCII box-drawing diagrams requiring consistent readability.

The validator works with Markdown files and documentation containing ASCII box-drawing diagrams. It processes single files, directories, or entire projects, making it suitable for diverse documentation structures and repository layouts.
