VS Code integration for Alfa's D Formatter.

The repository includes the version-matched adfmt-0.3.0.vsix package for offline installation and release verification.

Features

Formats D documents with adfmt.
Registers .d files as the d language even when no separate D extension is installed.
Selects alfa.adfmt as the default D formatter. Format-on-save remains an explicit user or workspace choice.
Recognizes extensionless .adfmt files as YAML.
Provides validation, completion, and hover documentation for .adfmt through the Red Hat YAML extension.
Uses the nearest .adfmt file because the formatter runs with the source document's directory as its working directory.
Creates or opens a project .adfmt file with the adfmt: Create or Open Configuration command.
Rejects in-place CLI arguments that are incompatible with VS Code's standard-input formatting protocol.
Stops formatter processes that exceed the configurable timeout.
Limits retained formatter output and handles early stdin closure safely.
Passes the real source path to adfmt so filename-specific EditorConfig rules behave the same in VS Code and the CLI.
Detects the default Inno Setup installation at %LOCALAPPDATA%\Programs\adfmt\adfmt.exe on Windows.

Requirements

Install adfmt and make it available on PATH. Alternatively, set:

{
  "adfmt.executablePath": "/absolute/path/to/adfmt"
}

The Red Hat YAML extension is installed automatically as an extension dependency.

For full D syntax highlighting, completion, diagnostics, and navigation, install code-d. Keep d.enableFormatting disabled when using adfmt so code-d's dfmt integration does not compete with this formatter.

Settings

adfmt.executablePath: executable path or command name.
adfmt.arguments: additional command-line arguments.
adfmt.formatTimeout: formatting timeout in milliseconds.
adfmt.maxOutputBytes: memory limit for each formatter output stream.
adfmt.trace.server: output-channel logging level.

Commands

adfmt: Check Installation: verifies that the configured executable starts.
adfmt: Create or Open Configuration: creates a minimal .adfmt in the selected workspace folder, or opens the existing file.
adfmt: Show Output: opens formatter diagnostics.
