Overview

Test 1: Indentation / ネスト構造

Scrapbox uses leading spaces for nesting. Previously, md2sb stripped all leading whitespace.

Level 1 indentation (1 space)

Level 2 indentation (2 spaces)

Level 3 indentation (3 spaces)

Level 4 indentation (4 spaces)

Back to level 3

Back to level 2

markdown: string,

options?: ConvertOptions

let result = md2sb(markdown);

result = result.replace(

# Example: batch page creation

import requests

def create_page(title, body, format="scrapbox"):

"""Create a Cosense page via MCP server."""

return mcp.call("create_page", {

"title": title,

"body": body,

"format": format # NEW: bypass md2sb

Test 6: Tables / テーブル

Scenario format param Expected Actual Status

Indentation (scrapbox) scrapbox preserved preserved ✅ Pass

Code blocks (scrapbox) scrapbox preserved preserved ✅ Pass

Mixed syntax (scrapbox) scrapbox raw passthrough raw passthrough ✅ Pass

Test 7: Icons and images / アイコン

Test 8: Mathematical notation

$ e^{i\pi} + 1 = 0

$ \sum_{k=1}^{n} k = \frac{n(n+1)}{2}

$ \int_0^\infty e^{-x^2} dx = \frac{\sqrt{\pi}}{2}

Test 9: Blockquote / 引用
