CurlyBlocks — Add Missing Curly Braces

CurlyBlocks adds curly braces to if, else if, else, for, while, and do...while statements whose body is a single statement written without braces.

Example

// Before
if (x > 0) console.log(x);

// After
if (x > 0) {
    console.log(x);
}

Usage

• Run CurlyBlocks: Add Missing Curly Braces from the Command Palette, the editor context menu, or with Ctrl+Shift+C (Cmd+Shift+C on macOS).
• With no selection, the whole document is processed. With one or more selections, only the selected ranges are processed.
• Indentation follows the editor's tab/space settings.

Features

• Adds braces to single-statement if / else if / else / for / while / do...while bodies.
• Leaves already-braced blocks untouched, so running it repeatedly is safe.
• Skips control keywords that appear inside strings, template literals, comments, and regular-expression literals.
• Leaves a body untouched when its extent is ambiguous rather than risk changing the meaning of the code.

Supported languages

By default the command runs on these language identifiers:

javascript, javascriptreact, typescript, typescriptreact, c, cpp, csharp, java, go, rust, php, dart, groovy, kotlin, swift, scala.

Change the list with the curlyBlocks.languages setting.

Limitations

• The formatter is text-based, not a full parser. It wraps a body only when its boundary is unambiguous; bodies inside the parenthesised header of a statement are not reformatted.
• try / catch / finally already require braces in JavaScript, so they are not modified.
