Wire: Automated Initialization in Go

Note

This repository is a fork of google/wire, maintained by verystar. It is intended for internal use by the VeryStar team only; external projects should depend on the upstream google/wire or another community fork instead. The upstream project is no longer maintained; this fork continues maintenance with a focus on Go toolchain compatibility and bug fixes.

The module path is github.com/verystar/wire. Existing internal projects can adopt this fork without changing their imports:

go mod edit -replace=github.com/google/wire=github.com/verystar/wire@latest

Wire is a code generation tool that automates connecting components using dependency injection. Dependencies between components are represented in Wire as function parameters, encouraging explicit initialization instead of global variables. Because Wire operates without runtime state or reflection, code written to be used with Wire is useful even for hand-written initialization.

For an overview, see the introductory blog post.

Installing

Install Wire by running:

go install github.com/verystar/wire/cmd/wire@latest

and ensuring that $GOPATH/bin is added to your $PATH.

Project status

This fork follows a preserve, not extend policy: wire's core invariant — dependency identity is Go type identity (types.Identical) — is kept unchanged, and no new feature surface is planned. Maintenance is limited to compatibility with new Go releases and bug fixes.

Diverges from upstream google/wire so far:

• Module path renamed to github.com/verystar/wire (imports and the generated //go:generate directive point to this fork).
