gcraft#

Go Code Craftsman — a CLI that reads your struct and interface definitions with go/ast and generates the boilerplate you’d otherwise write by hand: Builder, Validator, Clone, and Mock.

No reflection at runtime. No code templates to maintain. Just plain, idiomatic Go you can read, debug, and check into version control.

go install github.com/Mahdyaralipor/gcraft/cmd/gcraft@latest

gcraft generate -type User -src ./user.go

u := NewUserBuilder().
    WithName("Ada").
    WithEmail("ada@example.com").
    Build()

What it generates#

Feature	Flag	What you get
Builder	`-builder`	Fluent `With...()` methods for constructing instances
Validator	`-validate`	A `Validate() error` method
Clone	`-clone`	A `Clone()` deep-copy method
Mock	`-mock`	A mock implementation, for interfaces

All four are generated by default — disable any of them with =false.

👉 Start with Installation, then Getting Started.
