Features

• Single-Command Formatting: Use the standard VS Code “Format Document” command to instantly reformat your DBML file.
• DBML Validation: Leverages @dbml/core internally to parse your file, ensuring it’s syntactically correct.
• No Reordering of References: Keeps your references exactly where you placed them, only adjusting spaces and indentation (according to the code you’ve integrated).
• Indentation & Spacing: Removes excessive whitespace and enforces consistent spacing around tokens.
• Smooth Integration: Automatically activates when you open a .dbml file in Visual Studio Code.
