Examples

Handle errors quickly

err := doSomething()
// Press Ctrl+. and choose from:
// - Handle error: return err
// - Handle error: return wrapped
// - Handle error: log and return

Add JSON tags to all struct fields

type User struct {  // <- Press Ctrl+. here
    Name    string
    Email   string
    Age     int
}
// Transforms to:
// Name    string `json:"name"`
// Email   string `json:"email"`
// Age     int    `json:"age"`

Extract to variable

result := calculateSomething(a + b * c)  // Select "a + b * c" and press Ctrl+.
// Transforms to:
// name := a + b * c
// result := calculateSomething(name)
