mdv v1.3.4

mdv

A tiny markdown validator. It understands GFM auto-links, and returns an exitCode of 1 if any rules are violated, making it suitable for use in CI environments. It is in use by the OpenAPI Specification, the RAML Specification and the AsyncAPI Specification, amongst others.

Errors

• Undefined internal link targets - missingAnchors[]
• Duplicated internal link targets - duplicatedAnchors[]
• Anchors containing the # character - anchorsWithHash[]
• Links with empty text - anchorsWithEmptyText[]
• Local Refs without # character - localRefNoHash[]
• Images without an alt tag - imagesWithMissingAlt[]
• yaml, json, xml or abnf examples which do not parse - nonParsingExamples[]

Warnings

• Internal manually-defined anchors with no links pointing to them
• Code-blocks with no language specified - codeBlocksWithNoLanguage
• Four or more leading backticks at the beginning of a line
