markdown-it-prism
markdown-it plugin to highlight code blocks using Prism
Usage
const md = require('markdown-it')();
const prism = require('markdown-it-prism');
md.use(prism, options);
The plugin will insert the necessary markup into all code blocks. Include one of Prism’s stylesheets in your HTML to get highlighted code.
Options
The options
object may contain:
| Name | Description | Default |
|---------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------|
| highlightInlineCode
| Whether to highlight inline code. | false
|
| plugins
| Array of Prism Plugins to load. The names to use can be found here. Please note that some prism plugins (notably line-numbers) rely on the DOM being present and can thus not be used with this package (see #1). | []
|
| init
| A function called after setting up prism. Will receive the prism instance as only argument. Useful for plugins needing further intialisation. | () => {}
|
| defaultLanguageForUnknown
| The language to use for code blocks that specify a language that Prism does not know. No default will be used if this option is undefined
. | undefined
|
| defaultLanguageForUnspecified
| The language to use for code block that do not specify a language. No default will be used if this option is undefined
. | undefined
|
| defaultLanguage
| Shorthand to set both defaultLanguageForUnknown
and defaultLanguageForUnspecified
to the same value. | undefined
|
Inline Code
When highlightInlineCode
is set, inline code will be highlighted just like fenced code blocks are.
To specifiy the language of inline code, add {language=<your-language>}
after the code segment:
`class Demo { };`{language=cpp}
This syntax is compatible with markdown-it-attrs:
The language=<x>
part will be stripped, but everything else between {
and }
will work
with markdown-it-attrs as usual.
Usage with Webpack
If you want to use this plugin together with Webpack, you need to import all languages you intend to use:
import MarkdownIt from 'markdown-it';
import prism from 'markdown-it-prism';
import "prismjs/components/prism-clike"
import "prismjs/components/prism-java"
function component() {
const md = new MarkdownIt();
md.use(prism);
const element = document.createElement('div');
element.innerHTML = md.render(`
Here is some *code*:
\`\`\`java
public class Test {
public void foo() {}
}
\`\`\`
`);
return element;
}
document.body.appendChild(component());
Beware: Prisms languages have dependencies onto each other. You need to import the languages together with their dependencies in the correct order.
