create_block
Add bullet-point content to Logseq pages. Specify page name and content, optionally include properties. Automatically formats as bullet points and supports page links with [[Page Name]] syntax.
Instructions
Creates a new block on a page in the Logseq graph.
IMPORTANT NOTES:
1. All blocks are automatically formatted as bullet points in Logseq UI
2. To create links to other pages, use double brackets: [[Page Name]]
When creating blocks on journal pages:
- The block will inherit the "journal?" and "journalDay" attributes from the page
- "journalDay" will be in YYYYMMDD format (e.g., 20250404 for April 4, 2025)
Args:
page_name (str): The name of the page to create the block on.
content (str): The content of the new block.
properties (dict, optional): Properties to set on the new block.
Returns:
dict: Information about the created block.Input Schema
