micromark extension to support kbd element syntax with configurable delimiters, escaping, var sequences, and arbitrary nesting (e.g. Ctrl + key).
Docs at shivjm.github.io/remark-extensions.

Install

This package is ESM only: Node 18+ is needed to use it and it must be imported instead of required.
npm install micromark-extension-kbd-nested

## Use

```js
import {micromark} from 'micromark'
import {
  html,
  syntax
} from 'micromark-extension-kbd-nested';

const output = micromark('Press ||| ||Ctrl|| + || \| || |||, then || //key// ||.', {
  extensions: [syntax()],
  htmlExtensions: [html]
})

console.log(output)

Yields:

<p>Press <kbd><kbd>Ctrl</kbd> + <kbd>|</kbd></kbd>, then <kbd><var>key</var></kbd>.</p>

Syntax

Keyboard sequences

Recognizes any sequence of two or more unescaped occurrences of delimiter (defaults to |) as a keyboard sequence.

• All is preserved except immediately after an opening sequence or

immediately before a closing sequence.

• Nesting is possible by using a longer sequence on the outside and a

shorter sequence on the inside, e.g. ||| ||Ctrl|| + ||x|| ||| will be turned into Ctrl + x.

• The opening sequence will be considered to end at the first

whitespace character or non-delimiter, including escape characters. For example, these will all produce <kbd>|</kbd>: ||\||| || | || || | || ++|++ (with a delimiter of +) ++ | ++ (with a delimiter of +)

Variable sequence

variableDelimiter (defaults to /) can be used within keyboard sequences to mark variable sections.

• Must always use two variable delimiters.
• Cannot be nested.
• All is preserved except immediately after an opening sequence or

immediately before a closing sequence.

API

This package exports the following identifiers: html, syntax. There is no default export.

html

Extension for micromark to compile as <kbd> and <var> elements (can be passed in htmlExtensions).

syntax(options?)
