Marksman

Write Markdown with code assist and intelligence in the comfort of your favourite editor.

Marksman is a program that integrates with your editor to assist you in writing and maintaining your Markdown documents. Using LSP protocol it provides completion, goto definition, find references, rename refactoring, diagnostics, and more. In addition to regular Markdown, it also supports wiki-link-style references that enable Zettelkasten-like[^roam-research]^, [^markdown-memo] note taking. See more about Marksman's features below.

Marksman works on MacOS, Linux, and Windows and is distributed as a self-contained binary for each OS.

The server provides assistance with:

• Markdown inline links:

  This is [inline link](/some-file.md#some-heading).
  This is an internal [anchor link](#heading).
  

• Markdown reference links:

  See [reference].
  
  [reference]: /url "Title"
  

• Wiki-links:

  Link to [[another-note]].
  Link to [[another-notes#heading]].
  Internal link to [[#a-heading]].
  

All types of links support completion, hover, goto definition/references. Additionally, Marksman provides diagnostics for wiki-links to detect broken references and duplicate/ambiguous headings.

Existing editor integrations[^lsp]:

• VSCode via Marksman VSCode.
• Neovim:
  • via mason.nvim (automatic server installation) (requires mason-lspconfig.nvim)
  • via nvim-lspconfig,
  • via CoC-marksman.
• Emacs:

  • via LSP Mode (automatic server installation).

    Example config for use-package users:

    (use-package markdown-mode
      :hook (markdown-mode . lsp)
      :config
      (require 'lsp-marksman))
    

  • via Eglot, requires configuration (unless eglot#1013 gets merged); add the following to your init.el

    (add-to-list 'eglot-server-programs '(markdown-mode . ("marksman")))      
    (add-hook 'markdown-mode-hook #'eglot-ensure)
    

• Helix supports Marksman out of the box. However, you need add marksman binary to your PATH manually.
• Sublime Text via LSP-marksman (automatic server installation).
• BBEdit can be configured to use Marksman as an LSP server for Markdown files.

How to install

FAQ

• Cross-file references and completions don't work.
  • Either create an empty .marksman.toml in the root folder of your project or initialize a repository (e.g. git init). See this page to learn more about single- and mult-file modes.
• I'm getting "marksman cant be opened because Apple cannot check it for malicious software" on MacOS.
  • Run the following command to bypass it and let Mac know that it's fine: xattr -d com.apple.quarantine <path-to-marksman-bin>.

[^roam-research]: You may have heard about Roam Research. That is a commercial implementation of the Zettelkasten method and another point of reference for what Marksman is about. However, unlike a proprietary Roam Research, Marksman is free, open-source and integrated into your favourite editor (albeit for not not as feature rich as Roam Research).

[^markdown-memo]: There is an excellent VSCode extension called Markdown Memo. You definitely need to check it out if you're primarily using VSCode as it has some features that are missing in Marksman and Marksman VSCode extension. However, Markdown Memo is VSCode specific while Marksman is a generic language server, so can be used with any editor that has LSP support: Emacs, Vim, Neovim, etc.

[^lsp]: Since Marksman is a regular Language Server most of the functionality works out of the box with any LSP client.

[^single-file-mode]: There is an initiative to add a single-file mode to LSP but it's not a part of the spec at least until and including v3.17.
