I'm looking for a Markdown formatter, and I'm quite particular about my Markdown style. I don't want it to be formatted in a generic Markdown style. For instance, I prefer a style that adheres to rules such as:

• 80 characters at most per line, except for code blocks and URLs.
• Prefer reference links over inline links.
• Prefer setext headings over ATX headings.
• Two new lines before opening an H1/H2 heading.
• One space before and two spaces after a bullet.
• Wrap file paths in asterisks.
• Wrap inline code in backticks.
• Wrap code blocks in quadruple tildes (~~~~), and specify the language with a single space after the opening tildes (e.g., ~~~~ bash).

Are there any Markdown formatters that allow for such detailed customization of these elements? Or would I have to build one myself?

@hongminhee I have been interested in something similar (short on time to implement myself). The real challenge I found is finding an AST generating library for Markdown that supports re-emitting an altered AST as Markdown with fidelity.

@hongminhee there are Markdown linters. There's a few of them and I know that Awesome lists use https://github.com/sindresorhus/awesome-lint which uses https://github.com/remarkjs/remark-lint — the rules can get quite… annoying 🫣
