Editor Support

SDIF editor support is currently provided through the Tree-sitter grammar in the tree-sitter-sdif repository. Any editor with Tree-sitter support can use this grammar for syntax highlighting.

File Extensions​

SDIF uses three file extensions:

  • .sdif — standard source documents.
  • .sdif.canon — canonical form output.
  • .sdif.ai — AI projection files.

You may need to configure your editor to associate these extensions with the SDIF language mode.

Editors with Confirmed Tree-sitter Support​

The following editors have built-in or well-established Tree-sitter integration:

Neovim​

Neovim supports Tree-sitter through the nvim-treesitter plugin. You can add tree-sitter-sdif as a custom parser. Refer to the nvim-treesitter documentation for instructions on registering a custom grammar from an external repository.

Helix​

Helix has Tree-sitter support built into the editor. Adding a custom language requires creating a languages.toml entry that points to the grammar repository. Refer to the Helix documentation on adding languages.

Zed​

Zed uses Tree-sitter as its primary parsing layer. Extension authors can bundle Tree-sitter grammars. Check the Zed extensions registry or the tree-sitter-sdif repository for current status.

Other Editors​

Editors like VS Code, Emacs, and others may support SDIF syntax highlighting through Tree-sitter-based extensions or language server integrations. These are not confirmed at this time. If you build or find an integration for another editor, contributions to the tree-sitter-sdif repository are welcome.
