title: TOML description: "Configure TOML language support in Zed, including language servers, formatting, and debugging."

TOML

TOML support is available through the TOML extension.

• Tree-sitter: tree-sitter/tree-sitter-toml

Language server

A TOML language server is available in the Tombi extension.

Tombi replies to language server requests for definitions by opening a scratch JSON buffer with the schema definition for some known formats (Cargo.toml, pyproject.toml, ...). Since Edit Predictions rely on looking up definitions, this leads to tabs opening when you edit the TOML file.

You can fix it by disabling definition requests in your Tombi configuration:

[lsp]
goto-type-definition.enabled = false

Alternatively, you can disable edit predictions in TOML buffers:

{
  "languages": {
    "TOML": {
      "show_edit_predictions": false // https://github.com/tombi-toml/tombi/issues/1556
    }
  }
}
