Expected behavior:

I'm seeing a similar issue to #5148. Prettier link

Input: *Content with under_score breaks italic in Hugo*

Output: _Content with under_score breaks italic in Hugo_

I'm formatting my Markdown blog posts for Hugo, and the Prettier version breaks italics:

I actually prefer * for bullet points and italics, so would it be possible to add an option for this? The bullet point italics don't break the markdown parser in Hugo.

Hugo uses the blackfriday markdown library for Go, so maybe it is a bug in there? I saw you mentioned that this should be valid Markdown, so maybe it's not a problem with Prettier.

But would be nice if there was the option to use *, to support broken parsers.

Another thing is that Prettier escapes dollar signs, but Hugo/blackfriday still renders the backslash in the HTML. E.g. $100 becomes \$100.

Is this another bug in blackfriday?

(I've decided to use "prettier.disableLanguages": ["markdown"] for now in VS Code, because the autoformatting is breaking my blog posts. Would be great to find a workaround for this.)

@ndbroadbent you can use https://spec.commonmark.org/dingus/ to check how it should render, according to the CommonMark spec.

Thanks! It looks like this is a bug in the blackfriday markdown parser then. (Although I'm not sure what they think about the CommonMark specification.)

Hi, I'm voicing support for this issue, as it conflicts with PHP Markdown Extra abbreviations.

The following

*[FPS]: frames per second

is automatically escaped to

\*[FPS]: frames per second

Fortunately it is easy enough to deal with using an ignore block:

<!-- prettier-ignore -->
*[FPS]: frames per second

But still kinda annoying 😄

Is there a way to set it up to ignore * in all Markdown files? I'd really like that instead of putting that comment every other line :/ Thanks for fix btw!
