markdownfmt

markdownfmt is a CLI that reformats Markdown files (like gofmt but for Markdown) and a library that you can use to generate well-formed Markdown files.

Features

• Full GitHub Flavored markdown support
• Fenced Code Blocks with longer info strings (see shurcooL#58)
• ATX-style headers (#, ##) by default

Installation

CLI

go install github.com/Kunde21/markdownfmt/v3/cmd/markdownfmt@latest

Library

go get github.com/Kunde21/markdownfmt/v3@latest

Usage

usage: markdownfmt [flags] [path ...]
  -d    display diffs instead of rewriting files
  -gofmt
        reformat Go source inside fenced code blocks
  -l    list files whose formatting differs from markdownfmt's
  -list-indent-style value
        style for indenting items inside lists ("aligned" or "uniform")
  -soft-wraps
        wrap lines even on soft line breaks
  -u    write underline headings instead of hashes for levels 1 and 2
  -w    write result to (source) file instead of stdout

The markdownfmt CLI supports the following execution modes:

• stdout: Write reformatted contents of provided files to stdout. This is the default.
• write (-w): Reformat and rewrite Markdown files in-place.
• list (-l): List files that would be modified, but don't change them.
• diff (-d): Display a diff of modifications that would be made to files, but don't change them.

History

markdownfmt began as a fork of shurcooL/markdownfmt targeting Goldmark instead of Blackfriday. It has since diverged significantly.
