Callout is being displayed twice after pageToMarkdown and toMarkdownString

[Mikescops]

My Notion page contains a Callout block, and when doing:

const mdblocks = await n2m.pageToMarkdown(id);
const mdString = n2m.toMarkdownString(mdblocks);

The blockquote is rendered twice because pageToMarkdown takes the child block and already make them as markdown in the parent when building MD blocks. This operation is done another time when toMarkdownString parses the blocks again.

Example of mdblocks:

 {
    "type": "callout",
    "blockId": "143eac7c-3bb3-801c-9f7e-e533b0665635",
    "parent": "> 📝 ### **A Simplified Analogy**  \n>   \n> Think of confidential computing as an ultra-secure vault:  \n>   \n> 1. **The Vault (Trusted Execution Environment or TEE):** This is a locked room where only specific operations can take place, shielded from everything outside. Even if a hacker (or a curious system admin) tried to gain entry to the vault, they’d see only encrypted gibberish.  \n>   \n> 2. **The Key (Encryption):** Only you—and those you trust—can unlock what’s inside. Even the company hosting the vault doesn’t have a spare key.",
    "children": [
      {
        "type": "heading_3",
        "blockId": "143eac7c-3bb3-8031-9fc2-ceb8475d347b",
        "parent": "### **A Simplified Analogy**",
        "children": []
      },
      {
        "type": "paragraph",
        "blockId": "143eac7c-3bb3-80cd-9f39-e031f41b5786",
        "parent": "Think of confidential computing as an ultra-secure vault:",
        "children": []
      },
      {
        "type": "numbered_list_item",
        "blockId": "143eac7c-3bb3-8050-901b-d988226c5beb",
        "parent": "1. **The Vault (Trusted Execution Environment or TEE):** This is a locked room where only specific operations can take place, shielded from everything outside. Even if a hacker (or a curious system admin) tried to gain entry to the vault, they’d see only encrypted gibberish.",
        "children": []
      },
      {
        "type": "numbered_list_item",
        "blockId": "143eac7c-3bb3-8007-9f42-e41c95fe37e9",
        "parent": "2. **The Key (Encryption):** Only you—and those you trust—can unlock what’s inside. Even the company hosting the vault doesn’t have a spare key.",
        "children": []
      }
    ]
  },

This can be easily solved by adding conditions in notion-to-md.ts file, I'll open a PR and let you look if it's the best solution.

Thank you, @Mikescops, for your contribution, truly appreciate it! 😊
v3.1.3 is now live.

I’d love to hear your feedback or see your input on the development of v4. Let me know how it addresses your use case or if you have any other use cases to share.

I think we missed something, if there are other blocks after the title in the callout they are not displayed

I think it's a matter of regex, maybe we could do something simpler to understand like this

    const formattedText = text.replace(/\n/g, "  \n> ");
    const formattedEmoji = emoji ? emoji + " " : "";
    const headingMatch = text.match(/^(#{1,6})\s/);
    if (headingMatch) {
        const headingLevel = headingMatch[1].length;
        return `> ${"#".repeat(headingLevel) + " "}${formattedEmoji}${formattedText.replace(headingMatch[0], "")}`;
    }
    return `> ${formattedEmoji}${formattedText}`;

Good catch, Tested it, look good. Will create a new release thank you :)

This solves the issue however there are a lot of edge cases that still needs to be handled and one of them being:

which ignores the child elements of the toggle and there are many such cases where a type of block can be accommodated inside another block.

---

The real issue is how inconsistently blocks are handled during rendering, especially the ones with child blocks. Honestly, the code I wrote here is a mess, and that's on me. Going forward, We need to make sure we clean this up in v4 and have a consistent block processing method that fits well with the renderer plugin and also gives enough flexibility to users to customize without much hassle.

Since this is not completely solved I'll mark it as candidate of v4 and probably plan out the development of v4.
