Installation

Install Elixir Hex Lens from the Zed extension marketplace (zed: extensions in the command palette).

Configuration

Custom server binary path

By default, the extension downloads the LSP server binary from GitHub releases. To use a custom binary (e.g. a local build), add this to your Zed settings.json:

{
  "lsp": {
    "elixir-hex-lens": {
      "binary": {
        "path": "/path/to/elixir-hex-lens-lsp"
      }
    }
  }
}

The extension resolves the server binary in this order:

Custom path from Zed settings (as shown above)
Cached path from a previous invocation
System PATH lookup
Download from GitHub releases
