markdown-it-kbd-better v1.2.5

markdown-it-kbd-better

This is a fork of markdown-it-kbd with some tiny improvements just for myself.

Notably, it includes the following changes:

• Support for replacing key names with values using a map (e.g. mac:cmd -> ⌘). Fully customizable in the options, add your own replacements or disable it completely. Comes with a built-in preset for replacing some common keys with icons. You could use this to make macros like copy to ⌘+C or win:ctrl to ⊞+Ctrl.
• Support for transforming key names with a custom function (e.g. adding a prefix to all keys or capitalizing them). Fully customizable in the options, add your own transformations or disable it completely.
• Support for case-sensitive key matching. Fully customizable in the options, disable it if you don't need it.

Installation

npm i markdown-it-kbd-better
pnpm add markdown-it-kbd-better
yarn add markdown-it-kbd-better

Usage

const markdownIt = require('markdown-it');
const markdownItKbd = require('markdown-it-kbd-better');

const md = markdownIt().use(markdownItKbd);

Options

presets

Default: []

Enable built-in presets. Currently, the only built-in preset is icons, which replaces keys like cmd with ⌘, but more may be added in the future (feel free to open an issue if you have a suggestion).

To enable the icons preset, use the following:

.use(markdownItKbd, {
    presets: [{
        name: 'icons'
    }]
});

You can optionally pass prefix as well, which is used to prefix the key name. For example, if you wanted to match icon:cmd (prefixed with icon:) instead of cmd, you could use the following:

.use(markdownItKbd, {
    presets: [
        {
            name: 'icons',
            prefix: 'icon:'
        }
    ]
});

keyMap

Default: {}

A map of keys and values to replace. If the content of a KBD element is present in this map, it will be replaced with the corresponding value.

For example, you could replace win with ⊞:

.use(markdownItKbd, {
    keyMap: {
        win: '⊞'
    }
});

caseSensitive

Default: false

Whether or not to match keys in a case-sensitive manner. If this is set to false, all keys will be converted to lowercase before being matched. Otherwise, they will be matched exactly as they appear in the map.

transform

Default: return content; (no transformation)

A function that transforms the content. This is useful for things like capitalizing the key name or adding a prefix to it.

For example, you could capitalize all key names:

.use(markdownItKbd, {
    transform: (content: string) => {
        return content.toUpperCase();
    }
});

Or you could add a text to all key names:

.use(markdownItKbd, {
    transform: (content: string) => {
        return `Key: ${content}`;
    }
});
