Support nested code blocks and blockquotes in lists

Initial checklist

• I read the support docs
• I read the contributing guide
• I agree to follow the code of conduct
• I searched issues and couldn’t find anything (or linked relevant results below)

Problem

Hi team,
Is it possible to support such structural conversion?

1. milk
	> banana
2. cheese

Expect

[
	{
		type: "list",
		children: [
			{ type: "list item", ... },
			{ type: "blockquote", ... },
			{ type: "list item", ... },
		]
 	}
]

Actual

[
	{
		type: "list",
		children: [
			{ type: "list item", ... },
		]
 	},
	{ type: "blockquote", ... },
	{
		type: "list",
		children: [
			{ type: "list item", ... },
		]
 	}
]

The markdown works fine in GitHub

1. milk

   banana

2. cheese

---

1. milk

   banana
   

2. cheese

---

Solution

What you want is not possible, and it is not needed.

Lists have list items. On GH too. You cannot remove the list items. And you do not need to.

The block quote is inside the item. On GH too.

import {fromMarkdown} from 'mdast-util-from-markdown'
import {removePosition} from 'unist-util-remove-position'

const document = `1. milk
	> banana
2. cheese`
const tree = fromMarkdown(document)
removePosition(tree, {force: true})

console.dir(tree, {depth: null})

{
  type: 'root',
  children: [
    {
      type: 'list',
      ordered: true,
      start: 1,
      spread: false,
      children: [
        {
          type: 'listItem',
          spread: false,
          checked: null,
          children: [
            {
              type: 'paragraph',
              children: [ { type: 'text', value: 'milk' } ]
            },
            {
              type: 'blockquote',
              children: [
                {
                  type: 'paragraph',
                  children: [ { type: 'text', value: 'banana' } ]
                }
              ]
            }
          ]
        },
        {
          type: 'listItem',
          spread: false,
          checked: null,
          children: [
            {
              type: 'paragraph',
              children: [ { type: 'text', value: 'cheese' } ]
            }
          ]
        }
      ]
    }
  ]
}

Thanks you @wooorm , that construction you got works for me!
I am using mdast-util-from-markdown 2.0.0, and called fromMarkdown like this:

const tree: Parent = fromMarkdown(text, {
	extensions: [gfmStrikethrough(), gfmTable(), gfmTaskListItem()],
	mdastExtensions: [gfmTableFromMarkdown(), gfmStrikethroughFromMarkdown(), gfmTaskListItemFromMarkdown()],
}) as Parent;

But got the tree different from yours:

tree {
	type: 'root',
	children: [
		{
			type: 'list',
			ordered: true,
			start: 1,
			spread: false,
			children: [Array],
			position: [Object]
		},
		{ type: 'blockquote', children: [Array], position: [Object] },
		{
			type: 'list',
			ordered: true,
			start: 2,
			spread: false,
			children: [Array],
			position: [Object]
		}
	],
	position: {
        start: { line: 1, column: 1, offset: 0 },
        end: { line: 4, column: 1, offset: 29 }
	}
}

Do you know how this happened? Huge thanks!

Can you show the actual code and versions? I am quite sure text is different from what you post here

[wooorm]

And make your reproduction smaller: remove everything that is not needed. Remove every extension that’s not needed.

weird, If I pass in the string you used directly, I can get the same result as yours. If I read the markdown from another md file, I will get the incorrect result.
10-quote-in-list.md

[wooorm]

It’s not weird, it’s well specified! ;) It’s the difference between 2 spaces and a tab. In markdown, that tab there is worth 4 spaces.

You do not use enough spaces.
Take this: the block quote is not in the list item.

1. milk
> banana

Same with this, 1 is not enough:

1. milk
 > banana

Same, 2 is not enough:

1. milk
  > banana

Because 1 and . and are 3, you need 3 spaces:

1. milk
   > banana

Thank you very much! It works now:)
