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?

      The anchor hash feature currently creates a span object <span id="20231110120736-ze6m41f"></span>. Some kind of program should be able to understand and find this block inside the note as reference. Can anyone help me understand how this can be useful after export, where do I use this, which program understands this syntax?

      The export mode Anchor hash for notebook Markdown exporting has some limitations.

      In the case i want to publish a particular note (with links to other notes) my approach is:

      1. From main notebook export the notebook you want to publish to file
      2. Create new (temporary) notebook
      3. import file to new temp notebook
      4. Export temp notebook export it to any selectable format (only markdown is currently selectable)

      Other limitation of Anchor has export and the only way I got it to work (performed testing by exporting to Obsidian):

      • currently only works for notebook and does not allow nested notes. In the process of exporting all notes must be unnested inside notebook for .md export to function.
      • Currently does not support block reference. Can only link to main note. Tested by importing to obsidian (not a siyuan issue, but a markdown syntax limitation i presume)

      Depending on the responses here I might add a feature request soon that involves the concept of user selectable export syntax. In which before execution of export using anchor hash a user can type in the conversion syntax to apply. User is presented with input fields much like the settings > Export > Anchor text wrapping symbol fields.

      Conversion syntax for siyuan > obsidian would be: [[ 2#^d8bf62|Note 2]] and conversion input fields could somehow be [[ .. / .. #^ .. | .. ]]

      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

      @88250 I think this is an important missing feature when it comes to publishing the notes. Let me explain:

      Many users, including me, like to make a lot of links between notes. We also like to publish some set of notes on our websites/blogs/digital gardens. With most other note-taking software, you can export the notes to markdown, which includes links to other markdown documents (or even specific paragraphs in the markdown documents). Then, static site generators like Hugo can ingest the markdown files and produce HTML pages for the web. These HTML pages have all the correct links to other notes' HTML pages. With SiYuan, since the exported markdown does not contain links to other notes, publishing notes with links to other notes is not possible at all. I think this is a problem for many potential users. Do you have any other suggestions for how to publish notes in SiYuan with all links-between-notes working properly?

      I think this is important for another reason: With other tools like Obsidian, the notes are stored as normal markdown files. This means that the notes are not "trapped" inside the note-taking software. SiYuan does not store content as markdown files. Even if the format is still open, it still feels like the notes are "trapped" or "locked inside" SiYuan. If SiYuan has an excellent ability to export the notes to markdown (e.g. with all the links preserved) it would feel less like the notes are locked away inside SiYuan. I think this will increase trust in SiYuan, since users will not worry that if SiYuan unfortunately disappears, then their notes will disappear with it.

      I understand that because SiYuan offers a lot more complex formatting options, exporting to Markdown with everything properly preserved is not possible. This comes from the limitations of Markdown. However, there should ideally be a way to publish the notes (perhaps to HTML) so that all the formatting and links are preserved. I think maybe this is currently possible for each entry in the Doc Tree, but ideally, it should be possible for an entire hierarchy in the Doc Tree i.e. a given note and all notes below it should be exported. Please let me know if this is already possible.

      You're welcome! I actually was too lazy to write it myself so I asked ChatGPT to do it for me and changed some mistakes in its code.

      And I might as well do it for non-document blocks, I will post the solution here too.

      In any case, it seems like this problem can be solved easily and be integrated into SiYuan.
      I am not familiar with SiYuan code or Golang in general so someone else more familiar may make a Pull Request for this feature way faster than me.
      If not, I don't mind spending some time to learn enough to build this feature into SiYuan. It's the least I can do in return for getting this amazing app for free!
      Thanks @88250 @sagar and long live the open source!
