mdfmt

Overview ¶

Command mdfmt canonicalizes the formatting of a Markdown document.

Usage:

mdfmt <inp.md >out.md

For now, only whitespace is canonicalized:

• Trailing whitespace is removed from each line;
• Multiple blank lines are collapsed down to one;
• Before each heading line (that begins with #), a blank line is added for each heading level being unwound.

For example, given this input:

# Heading 1a

some text
## Heading 2

more text

# Heading 1b

This program will produce:

# Heading 1a

some text

## Heading 2

more text

# Heading 1b
