eloquent
Generate fluent APIs in Go.
A "fluent" API is sometimes called the "builder pattern": method chaining is used to optionally set values on an object.
Such methods are tedius to write by-hand, because there is no logic.
This tool writes the methods for you. Invoke with go generate, or manually.
Usage
// foo.go
//go:generate eloquent $GOFILE
type Foo struct {
// First doc comment.
First string
// Second doc comment.
Second bool
Third int
ignored float32
}go generate
// foo_eloquent.go
// WithFirst doc comment.
func (f Foo) WithFirst(s string) Foo {
f.First = s
return f
}
// WithSecond doc comment.
func (f Foo) WithSecond(b string) Foo {
f.Second = b
return f
}
func (f Foo) WithThird(n string) Foo {
f.Third = n
return f
}// main.go
func main() {
foo := NewFoo().
WithFirst("first").
WithSecond(false).
WithThird(3)
