Features

• Linting of markdown documents
• Link checking

Specifications

This repository checks against following specification:

• Markdown Commonmark

Prerequisites

Install the Node.js 18 Active LTS version of Node.js (which includes npm).

Installation

For linting and all the checks you need several npm packages. The following command installs all necessary npm dependencies:

npm install

This installs all dependencies into a local node_modules folder.

Checks

To enforce specification conformity there are several checks defined as npm run-script targets. To run all checks please execute:

npm test

Individual checks

If you want to run individual checks see the targets and the description below. Every individual check can be run like so:

npm run-script my-individual-check

See the package.json file for the currently available scripts.

Markdown linter

Markdown linting. See the rules here.

npm run-script markdownlint

Markdown linter overrides

Sometimes it is not possible to be commonmark conform. In these rare cases an inline tag to skip linting is possible.

Candidates are tables.

<!-- markdownlint-disable-->
| Column 1 | Column 2 | Column 3 |
|----------|----------|----------|
<!-- markdownlint-enable-->

Additionally HTML image tags can be allowed globally. This is useful if you need to resize images, since commonmark has no annotation for this.

This is done with a .markdownlint.json override file which would look something like this:

{
    "no-inline-html": {
        "allowed_elements": [
            "img",
            "table"
        ]
    }
}

For more information how to tweak overrides consult the markdown linter documentation mentioned above.

Link resolver

All cross references and external URLs are resolved.
