Duckling Language Server
The language support for Duckling programming language.
This is the official extension provided by the Duckling team.
The extension starts the duck_ls binary and talks to it over stdio. Syntax highlighting,
bracket matching and the rest of the editor configuration are contributed by the extension
itself, so they keep working with the server turned off or missing.
Configuration
The extension looks for the duck_ls binary at ~/.local/bin/duck_ls by default.
Open VS Code Settings (Ctrl+,) and search for Duckling, or edit settings.json:
| Setting |
Description |
Default |
DucklingLanguageSupport.enable |
Run the language server. Turn off to keep only syntax highlighting. |
true |
DucklingLanguageSupport.executablePath |
Path to the duck_ls binary. Supports ~. |
~/.local/bin/duck_ls |
DucklingLanguageSupport.trace.server |
Traces the communication with the server. |
messages |
{
"DucklingLanguageSupport.executablePath": "/custom/path/to/duck_ls"
}
Both settings take effect immediately: changing either one restarts the server, and no window
reload is needed. Duckling: Restart language server in the command palette restarts it by
hand.
No server
With DucklingLanguageSupport.enable set to false the extension never starts duck_ls.
The same happens, with a warning, when no binary is found at the configured path.
