Paragraphs and Line Breaks

This is the first paragraph. It has multiple sentences. All sentences should flow together as a single block of text without any unexpected line breaks.

This is the second paragraph. There should be visible spacing between this and the paragraph above.

This line has two trailing spaces to force a hard line break. This should appear on the next line within the same paragraph.

This line uses a backslash
for a hard line break as well.

Links

An inline link with title: Example

A bare URL: https://example.com/path?query=value&other=true

A bare email: user@example.com

Code Blocks

Fenced with Backticks

Plain code block with no language specified.
It should render in a monospace font.
    Indentation should be preserved.

// C# code block
using UnityEngine;

public class Example : MonoBehaviour
{
    [SerializeField] private float _speed = 5f;

    private void Update()
    {
        var direction = new Vector3(
            Input.GetAxis("Horizontal"),
            0f,
            Input.GetAxis("Vertical")
        );
        transform.position += direction * (_speed * Time.deltaTime);
    }
}

# Python code block
def fibonacci(n: int) -> list[int]:
    """Generate the first n Fibonacci numbers."""
    if n <= 0:
        return []
    sequence = [0, 1]
    while len(sequence) < n:
        sequence.append(sequence[-1] + sequence[-2])
    return sequence[:n]

for i, num in enumerate(fibonacci(10)):
    print(f"F({i}) = {num}")

{
  "name": "com.xrcadia.test",
  "version": "1.0.0",
  "displayName": "xrcadia.test",
  "description": "A test package.",
  "unity": "6000.3",
  "author": { "name": "xrcadia" },
  "keywords": ["test", "markdown"],
  "dependencies": {}
}

// JavaScript with special characters
const encode = (s) => s.replace(/&/g, '&amp;').replace(/</g, '&lt;').replace(/>/g, '&gt;');
const msg = `Hello <world> & "friends"`;
console.log(encode(msg)); // Hello &lt;world&gt; &amp; &quot;friends&quot;

Code block with <angle brackets> & ampersands & "quotes"
These should not be interpreted as HTML.
Special: <b>not bold</b> <i>not italic</i>

Fenced with Tildes

Code block using tilde fencing.
This is an alternative to backtick fencing.

Indented Code Block

This is an indented code block.
Each line is indented by four spaces.
It should render identically to fenced blocks.

  - Completed task inside nested list

Blockquote containing:

An ordered list

With bold items

And nested unordered items
And a code block inside the blockquote
And A Table

In A Quote

And	A	Table
In	A	Quote

Edge Cases

Empty Sections

Consecutive Headings (no content between)

Sub-heading immediately after

Very Long Heading That Goes On And On And Should Eventually Wrap To Multiple Lines In The Viewer To Test Heading Overflow Behavior

Heading with only `code`

Fully Bold Heading

Fully Italic Heading

A paragraph with a very long unbroken word: Pneumonoultramicroscopicsilicovolcanoconiosis and then normal text continues after it.

A paragraph with a very long URL inline: https://example.com/very/long/path/that/goes/on/and/on/to/test/url/wrapping/behavior?with=query&params=too&and=more

Trailing Whitespace and Special Lines

A line followed by an empty line:

And then this line.

Multiple empty lines above (should collapse to single spacing).

And this line after multiple blanks.

Special Characters in Context

Pipes outside tables: | this | is | not | a | table |

Hashes not at line start: This is not ## a heading.

Backticks in prose: The command is `rm -rf` (double-backtick escape).

Asterisks in prose: 5 * 3 * 2 = 30 (should not become italic).

Underscores_in_words should not become italic.

An asterisk list marker right after a paragraph:

This should be a list item
And this too

Paragraphs with Mixed Inline Elements

This paragraph has bold, italic, code, ~~strikethrough~~, a link, and an image reference all mixed together in a single flowing block of text to test how the viewer handles complex inline rendering without breaking layout.

Here is a paragraph with a footnote¹, an abbreviation HTML, a code span, a bold segment containing nested italic and nested code, and a link with bold inside all in one go.

End of Test Document

If every section above renders correctly — with proper styling, spacing, nesting, and no raw markdown syntax leaking through — the viewer fully supports the Markdown specification.

This is the first footnote content. ↩ ↩²
This is a longer footnote with multiple paragraphs.

The second paragraph of the footnote is indented. ↩
