What is this?

This package is a preset containing remark-lint rules. Lint rules check markdown code style.

When should I use this?

You can use this package to check that markdown follows the Markdown Style Guide.

This uses the following style guide option system: wrap:space, header:atx, list-marker:hyphen, list-space:mixed, and code:fenced.

space-sentence

Both space-sentence:1 and space-sentence:2 are not supported by remark-lint as they relate to prose rather than markdown syntax. You could set-up remark-retext with retext-sentence-spacing to check this.

wrap

wrap:inner-sentence and wrap:sentence are not supported by remark-lint.

The default is wrap:space. To use wrap:no, turn off remark-lint-maximum-line-length like so:

1 "plugins": [
2   …
3   "remark-preset-lint-markdown-style-guide",
4+  ["remark-lint-maximum-line-length", false],
5   …
6 ]

header

The default is header:atx. To use header:setext, change the setting for remark-lint-heading-style like so:

1 "plugins": [
2   …
3   "remark-preset-lint-markdown-style-guide",
4+  ["remark-lint-heading-style", "setext"],
5   …
6 ]

list-marker

The default is list-marker:hyphen. For list-marker:asterisk or list-marker:plus, change the setting for remark-lint-unordered-list-marker-style like so:

1 "plugins": [
2   …
3   "remark-preset-lint-markdown-style-guide",
4+  ["remark-lint-unordered-list-marker-style", "*"],
5   …
6 ]

list-space

The default is list-space:mixed. For list-space:1, change the setting for remark-lint-list-item-indent like so:

1 "plugins": [
2   …
3   "remark-preset-lint-markdown-style-guide",
4+  ["remark-lint-list-item-indent", "space"],
5   …
6 ]

code

The default is code:fenced. For code:indented, change the setting for remark-lint-code-block-style like so:

1 "plugins": [
2   …
3   "remark-preset-lint-markdown-style-guide",
4+  ["remark-lint-code-block-style", "indented"],
5   …
6 ]

API

This package exports no identifiers. It exports no additional TypeScript types. The default export is remarkPresetLintMarkdownStyleGuide.

unified().use(remarkPresetLintMarkdownStyleGuide)

Check that markdown follows “Markdown Style Guide”.

You can reconfigure rules in the preset by using them afterwards with different options.

Compatibility

Projects maintained by the unified collective are compatible with maintained versions of Node.js.

When we cut a new major release, we drop support for unmaintained versions of Node. This means we try to keep the current release line, remark-preset-lint-markdown-style-guide@6, compatible with Node.js 16.
