How it works

Blocks are scanned to normalize blank lines, heading spacing, list indentation, and fenced-code boundaries while preserving content lines. The formatter is line-oriented and does not rewrite prose or render HTML.

  • Consistent spacing improves source readability.
  • Fenced code is preserved because its contents may be executable.

Worked example

Format messy markdown
Add proper spacing around headings and blocks
Input
											# Title
Some text
## Section
More text
Output
												Formatted: # Title

Some text

## Section

More text

When to use this

README cleanup, static-site content, and pre-commit documentation checks format Markdown.

Edge cases

  • A heading-like line inside a fence remains code.
  • Four-space indentation can be a code block and should not become a list.
  • Two trailing spaces can encode a hard line break.
