Ruben J. Jongejan

Ruben J. Jongejan is an independent software publisher maintaining projects through a public GitHub presence, with a catalog focused on developer tooling. The publisher's product range centers on rumdl, a fast Markdown linter and formatter written in Rust. As a linter, the tool analyzes Markdown documents to detect style inconsistencies, structural problems, and common formatting errors, helping authors enforce consistent conventions across documentation. As a formatter, it automatically rewrites files to comply with configurable rules, reducing the manual effort required to keep text clean and uniform. The choice of Rust as the implementation language reflects a common pattern in modern command-line tooling, prioritizing execution speed, memory safety, and straightforward distribution as a single binary. Software in this category typically serves documentation-heavy workflows: technical writers, open-source maintainers, and engineering teams use Markdown linting to keep README files, wikis, and documentation sites consistent, often integrating such tools into continuous integration pipelines or pre-commit hooks so that formatting checks run automatically before changes are merged. Formatting capabilities complement linting by fixing issues in place rather than only reporting them, which shortens review cycles and removes style debates from code review. The publisher's distribution through GitHub aligns with standard open-source practice, where source code, issue tracking, and release artifacts are available in one place, allowing users to inspect the implementation, report problems, and contribute improvements. With a catalog currently consisting of this single package, the publisher's offering is narrowly focused, targeting the niche of Markdown quality assurance rather than a broad suite of utilities, which is typical of independent developers concentrating effort on one well-defined problem in the documentation and developer-experience tooling space.
