Vale is a cross-platform (macOS, Windows, and Linux), command-line linter for prose built with speed and extensibility in mind. Its key features are as follows:
Markup support: Vale supports HTML, Markdown, AsciiDoc, reStructuredText, XML, and DITA—allowing it to avoid most syntax-related false positives.
Extensibility: Unlike most writing-related software, Vale's primary purpose isn't to provide its own advice; it's designed to enforce an existing style guide through its YAML-based extension system.
Performance: Vale typically takes less than 1 second to lint most files, making it fast enough to be included in test suites for large (> 1,000 files) repositories.
No matter if you're working with a small in-house standard or a large editorial style guide, Vale will help you maintain consistent and error-free writing.
