Heading One #

An edit.

Heading Two #

Heading Three #

Heading Four #

Normal paragraph text with bold content, italic content, and inline code. Some sentences are long enough that they will soft-wrap inside a narrow editing column, which exercises the renderer's line-wrapping logic and continuation indentation.

Bold at the start of a line and a line ending in italic.

Mixed: bold and nested italic inside bold — pulldown-cmark handles this correctly.

What about italic and nested bold?

==Highlighting test.==

==Highlighting test over bold, italic, and a link==

Lorem ipsum I don't actually have this memorized but it would ==probably== be somewhat in character for me to do so. I don't know if I'll even ==end up using== the highlight function because of how large the delimiters are but I wanted to have the ==option==.

Inline Elements #

A link to example in the middle of a sentence.

A bare link with a long URL: Rust documentation.

inline code at the start, middle of a sentence, and at the end too.

What happens when I type a long line? A long line? A line that goes on for a long long time?

Strikethrough.

Bold and italic combined with triple asterisks.

---

Blockquotes #

A single-line blockquote.

A blockquote that is long enough to soft-wrap inside the editing column, which means the renderer must correctly indent continuation lines to align with the text start after the left-edge indicator character.

Nested structure:

Second paragraph inside the same blockquote block.

Lists #

Unordered:

• First item
• Second item with bold inside
• Third item with inline code
  • Nested item one
  • Nested item two
• A really really really really really really really really really really long...
  • a nested really, really, really, really, really, really, really long...

Ordered:

1. First ordered item
2. Second ordered item
3. Third ordered item
   1. Nested ordered item

Task Lists #

• Unchecked todo item
• Checked and completed todo item
• Another unchecked item with bold content
• Another completed item
• What about a really, really, really, really, really, really, really, really long to-do item?
  • what about nesting a to-do item? A really, really, really, really long to-do item? Nice!

Fenced Code Blocks #

// Count vowels in a string slice and return a summary.
fn count_vowels(s: &str) -> usize {
    s.chars().filter(|c| "aeiouAEIOU".contains(*c)).count()
}

fn main() {
    let greeting = "Hello, world!";
    let n = count_vowels(greeting);
    println!("Vowels: {n}");  // 3

    let values: Vec<i32> = vec![1, 2, 3, 4, 5];
    let total: i32 = values.iter().sum();
    let doubled: Vec<i32> = values.iter().map(|&x| x * 2).collect();
    assert!(total > 0 && doubled.len() == values.len());
}

# Compute factorials up to n using recursion.
def factorial(n: int) -> int:
    if n <= 1:
        return 1
    return n * factorial(n - 1)

results = [factorial(i) for i in range(1, 6)]
total = sum(results)
print(f"Results: {results}")   # [1, 2, 6, 24, 120]
print(f"Sum: {total}")         # 153

A fenced block with no language tag:

plain text block

Tables #

Plain separator — pipes and dashes styled muted, no alignment colons:

Element	Style	Notes
Heading	Bold + accent color	Full-line bg tint
Bold	Bold weight	Includes delimiters
Italic	Italic + emphasis color	With fallback
Inline code	Code color + bg tint	Backticks included
Link	Underline + accent / muted	Split at ](

Alignment markers — colons in separator should appear in accent color:

Left-aligned	Centered	Right-aligned	None
code cell	bold cell	italic cell	plain
short	a longer value	42	text
left text	center text	999.99	more

---

Multi-byte Characters #

Café, naïve, résumé — accented Latin characters.

Japanese: 日本語のテキスト (Japanese text) — multi-byte UTF-8 sequences in a paragraph.

Emoji at end of line: 🦀

A heading with multi-byte content:

Ünïcödé Héàding #

Code block containing multi-byte characters:

# comment with emoji 🎉
value = "café"

Link with non-ASCII text: 日本語.

---

Edge Cases #

Empty blockquote line below:

A paragraph immediately after a heading with no blank line between them is unusual but valid Markdown.

Tight Heading #

Followed immediately by text.

Very long unbroken word that cannot be split at a space boundary and must be hard-wrapped by the renderer: superlongwordwithnospacesthatexceedsthecolumnwidthandmustbeforcebroken.

Asterisks that are not emphasis because they are unmatched: 2 * 3 = 6.

Backtick that is `not closed — just a literal character after this point.
