Description

Caps the ordered list item number at 999,999 to ensure that the output is correctly parsed as an ordered list by CommonMark parsers.

999999998. ok
999999999. limit
999999999. never be 10 digits here!
999999999. ditto

Numbers larger than it in MDX v1 are printed as are. (temporary measure)

Instead of Math.min, how about print the original when some list item mark (start +index) is greater than 999,999,999?

AST doesn't retain the original number of each list item. (only that of the first item) The current method is the easiest.

Maybe we can remove path.isFirst branch? node.start + path.index should work for first element too.

If you're not happy with the formatting algorithm for MDX v1, I'm prepared to just remove it and make it only for Markdown.

That should work, the linked issue is just an edge case, it's fine to wait until the mdx parser upgrade too.

I think MDXv1 uses printListLegacy and printList is used only by Markdown unless mdx is merged. Is it true?

Thank you! You are right, didn't notice there are two getPrefix.

It doesn't really matter much. All the parser === 'mdx' will be removed eventually anyway.

##### Markdown: Cap ordered list mark at 999,999,999 ([#&#8203;19351](prettier/prettier#19351) by [@&#8203;tats-u](https://github.com/tats-u))

CommonMark parsers only support ordered list item numbers up to 999,999,999.

With this change, Prettier now caps the ordered list item number at 999,999,999 to ensure that the output is correctly parsed as an ordered list by CommonMark parsers. Numbers larger than 999,999,999 are not parsed as list item numbers and are left unchanged in the output:

Do not remove `<>` from an inline link or image with an empty URL and a title, as this removal would change its interpretation.

This fixes the addition space before `+` in CSS `type()` declaration. For example `type(<number>+)` was being converted into `type(<number> +)` which is invalid CSS and does not work.

## [v3.9.5](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#395)

[diff](prettier/prettier@3.9.4...3.9.5)

##### Markdown: Cap ordered list mark at 999,999,999 ([#19351](prettier/prettier#19351) by [@tats-u](https://github.com/tats-u))

CommonMark parsers only support ordered list item numbers up to 999,999,999.

With this change, Prettier now caps the ordered list item number at 999,999,999 to ensure that the output is correctly parsed as an ordered list by CommonMark parsers. Numbers larger than 999,999,999 are not parsed as list item numbers and are left unchanged in the output:

##### Markdown: Avoid corrupting empty link with title ([#19487](prettier/prettier#19487) by [@andersk](https://github.com/andersk))

Do not remove `<>` from an inline link or image with an empty URL and a title, as this removal would change its interpretation.

<!-- prettier-ignore -->

```md
<!-- Input -->
[link](<> "title")

<!-- Prettier 3.9.4 -->
[link]( "title")

<!-- Prettier 3.9.5 -->

##### Less: Remove extra spaces after `[` in map lookups ([#19503](prettier/prettier#19503) by [@kovsu](https://github.com/kovsu))

<!-- prettier-ignore -->

  color: #theme[@@name];
}

// Prettier 3.9.4

##### CSS: Prevent addition space in `type()` with `+` ([#19516](prettier/prettier#19516) by [@bigandy](https://github.com/bigandy))

This fixes the addition space before `+` in CSS `type()` declaration. For example `type(<number>+)` was being converted into `type(<number> +)` which is invalid CSS and does not work.

<!-- prettier-ignore -->

```css
/* Input */
div {
  border-radius: attr(br type(<length>+));
}

/* Prettier 3.9.4 */
div {
  border-radius: attr(br type(<length> +));
}

/* Prettier 3.9.5 */
div {
  border-radius: attr(br type(<length>+));
}
```

##### CSS: Prevent addition space in `type()` with `+` ([#19516](prettier/prettier#19516) by [@bigandy](https://github.com/bigandy))

This fixes the addition space before `+` in CSS `type()` declaration. For example `type(<number>+)` was being converted into `type(<number> +)` which is invalid CSS and does not work.

<!-- prettier-ignore -->

```css
/* Input */
div {
  border-radius: attr(br type(<length>+));
}

/* Prettier 3.9.4 */
div {
  border-radius: attr(br type(<length> +));
}

/* Prettier 3.9.5 */
div {
  border-radius: attr(br type(<length>+));
}
```
