Changelog

Sourced from arcdown's changelog.

[2.0.0] 2022-08-03

Large-ish refactor to use a named class export.

import { Arcdown } from 'arcdown'

Added

• Arcdown class interface
• markdownItAnchor and markdownItToc *see "Changed" below

Removed

• default function as render interface
• markdown-it-toc-and-anchor *see "Changed" below

Changed

• class-based interfaces
• new table of contents plugin
  • markdownItTocAndAnchor retired
  • use markdown-it-anchor as markdownItAnchor for heading anchor creation
  • use markdown-it-toc-done-right as markdownItToc for table of contents
• lowercase arcdown changed to Arcdown

Fixed

• hljs plugin application in subsequent render calls
  • caused by instantiating hljs options on each render, solved with class structures
• handle codefence language specifiers with trailing spaces and meta info
  • this correctly loads the javascript language for syntax highlighting:

```javascript 12:42;foo-bar
