DAML — ZedExt

DAML for Zed

DAML language support for the Zed editor.

Features

Syntax highlighting for .daml files (via tree-sitter-haskell grammar with DAML keyword extensions)
Language server integration (damlc ide / damlc multi-ide)
Multi-package project support (automatic multi-ide for SDK >= 2.9.0)
Document outline (data types, functions, classes, instances)
Code completion with type signature display
Bracket matching and indentation
Text object selections

Requirements

DAML SDK installed and available in your PATH
Supports both dpm (preferred) and daml commands

Configuration

The extension works out of the box if dpm or daml is on your PATH. For custom setups, add to your Zed settings (Cmd+,):

{
  "lsp": {
    "daml-language-server": {
      "binary": {
        "path": "/path/to/dpm",
        "arguments": ["damlc", "ide"]
      }
    }
  }
}

Multi-IDE mode

For multi-package projects, the extension automatically uses damlc multi-ide when your daml.yaml declares SDK version >= 2.9.0. To force single-package mode, override the arguments:

{
  "lsp": {
    "daml-language-server": {
      "binary": {
        "arguments": ["damlc", "ide"]
      }
    }
  }
}
