Markdown Support

Overview

Feather supports GitHub Flavored Markdown (GFM) plus several extensions. Your markdown renders in real time in the preview pane using the Markdig parsing library.

Standard Markdown

  • Headings: # through ###### (H1 through H6)
  • Bold: **text** or __text__
  • Italic: *text* or _text_
  • Bold + Italic: ***text***
  • Ordered lists: Lines starting with 1., 2., etc.
  • Unordered lists: Lines starting with -, *, or +
  • Links: [text](url)
  • Images: ![alt text](url)
  • Blockquotes: Lines starting with >
  • Horizontal rules: ---, ***, or ___
  • Inline code: `code`
  • Fenced code blocks: Triple backticks with optional language for syntax highlighting

Syntax Highlighting

Fenced code blocks support language-specific highlighting via highlight.js. Specify the language after the opening backticks:

```javascript
const greeting = "Hello, world!";
```

GFM Extensions

Tables

Pipe-delimited tables with optional column alignment:

| Left | Center | Right |
|:-----|:------:|------:|
| a    |   b    |     c |

Task Lists

- [x] Completed item
- [ ] Unchecked item

Strikethrough

~~deleted text~~ renders as struck-through text.

Footnotes

Reference footnotes inline with [^1] and define them anywhere in the document:

This has a footnote[^1].

[^1]: The footnote content appears at the bottom.

Autolinks

URLs are automatically converted to clickable links without needing [text](url) syntax.

Emoji Shortcodes

Use :emoji_name: to insert emoji. For example, :smile: renders as a smiley face, :rocket: renders as a rocket.

Additional Extensions

Alert Blocks

Styled callout boxes using blockquote syntax:

> [!NOTE]
> Informational note.

> [!TIP]
> Helpful suggestion.

> [!IMPORTANT]
> Key information.

> [!WARNING]
> Potential issue.

> [!CAUTION]
> Dangerous action.

Each alert type renders with a distinct icon and color in the preview.

Definition Lists

Term
: Definition of the term.

Highlight / Mark

==highlighted text== renders with a background color that matches your current preview theme.

File Linking

  • Relative links to .md or .mdx files open in new tabs within Feather
  • Use the back/forward buttons (or Alt+Left / Alt+Right) to navigate between linked files
