Is it possible for markdown export to link to other files?

This post was last updated for 230 days ago, and the information may already be changed

I exported a notebook to markdown (which is great), but I found that the files don't have links to other files like they were in Siyuan.

So, is there anyway to make markdown exports have links to other files?

      I think the issue remains with anchor hash for the reason that it is limited to notebook currently, meaning I cannot select rendering from Markdown to HTML from the notebook_ex > export > (selectable=Markdown/

      How would i export my notes to HTML with anchor hash? I think I would be limited to using pandoc -o output.html, I tried it with pandoc, which succesfully creates html with link to other note, but it just opens the other note without navigation to the <span> block, so no hash jump in browser (brave/firefox) to block.

      @adham Wow 😍 You are a master programmer indeed! I was still trying to figure out how to use Python to open all .md files in a directory, by copy/pasting code from Stackoverflow 😄 This solution is exactly what I meant.

      I do believe it can be extended to include references to any arbitrary block, not just a document block. You did say that you don't want to mutate the linked documents, but I am just laying out the approach in case any other master programmers want to try it 😄. You wrote,

      I don't know how to find out if the link is of a block or a document,

      I see a few different possible checks for this

      • Look at the 'type' field in the response of the SQL query. If it is a document block, the type value will be 'd'. Other type values are given in the documentation at /Please Start Here/Advanced search/Type filtering
      • I believe that if the block is of type document, then the 'root_id' will be the same as 'id'. See the documentation of the SQL table fields at /Please Start Here/Advanced search/Database table

      So one or both of the above checks can be used to determine if the block is of type 'document' or something else.

      If the block is of type something else, then the way to link to it would be

      1. Open the target document that contains the block (i.e. the hpath)
      2. Search for the occurrence of the content in the 'markdown' field of the SQL query response. This will place the "cursor" inside the document to the start of the paragraph (or whatever other content) the block points to
      3. At this cursor position, insert an HTML anchor text like: <a name="block-id"></a>
      4. Then, update the siyuan://blocks/block-id part of the link to

      This approach enables having links in the markdown files to any other markdown files or parts inside markdown files.

      @adham Thank you once again for your example code 🙏

      In theory, programs that support standard Markdown (CommonMark) should be able to support parsing and rendering inline HTML elements, that is, <span>, but they may not necessarily support anchor hash jumps. After rendering from Markdown to HTML, the browser can support anchor hash jumping, so currently, exporting references as anchor hashs is the optimal solution.

      I was able to do it (for documents only, not blocks, as I don't know how to find out if the link is of a block or a document, and I don't want to mutate the linked documents anyway).

      Here's the Python script:

      import os
      import re
      import requests
      # Replace 'YOUR_API_ENDPOINT' with the actual Siyuan API endpoint
      SIYUAN_API_ENDPOINT = "http://localhost:6806"
      # Function to make a SQL query to Siyuan API
      def query_block_details(block_id):
          query = {"stmt": f"SELECT * FROM blocks WHERE id='{block_id}'"}
          response ="{SIYUAN_API_ENDPOINT}/api/query/sql", json=query)
          return response.json()
      # Function to process each markdown file
      def process_markdown_file(file_path):
          with open(file_path, "r", encoding="utf-8") as file:
              content =
              # Use regex to find instances of [Anchor text](siyuan://blocks/block-id)
              matches = re.findall(r"\[.*?\]\(siyuan://blocks/(.*?)\)", content)
              for block_id in matches:
                  # Query Siyuan API to get block details
                  result = query_block_details(block_id)
                  # Assumes ref is of a document, not a block
                  if result:
                      hpath_value = result["data"][0].get("hpath")
                      # Replace the siyuan://blocks/block-id with
                      new_link = f"({hpath_value}.md)"
                      # Replace the old link in the content
                      content = content.replace(f"(siyuan://blocks/{block_id})", new_link)
          # Write the updated content back to the file
          with open(file_path, "w", encoding="utf-8") as file:
      def process_markdown_directory(directory_path):
          for root, _, files in os.walk(directory_path):
              for file_name in files:
                  if file_name.endswith(".md"):
                      file_path = os.path.join(root, file_name)
      # Replace 'YOUR_MARKDOWN_DIRECTORY_PATH' with the actual path to your exported markdown files
      markdown_directory_path = "YOUR_MARKDOWN_DIRECTORY_PATH"
      # Process each markdown file in the specified path
