What it is

Wire is a compile-time code generation tool for Go that automates dependency injection by analyzing function signatures and generating initialization code. Rather than using runtime reflection or global state, Wire generates explicit wiring code that connects components—solving the boilerplate problem of manual dependency injection in Go applications while keeping the generated code readable and debuggable. Single-module layout: internal/wire/ contains the core analysis engine (analyze.go, parse.go, copyast.go, errors.go) with extensive testdata under internal/wire/testdata/ organizing ~15+ test scenarios (each with foo/, pkg/, want/ subdirectories for inputs and golden outputs). cmd/wire…

Start here

Read these in order:

• wire.go — Foundation: doesn't import anything internally and is imported by 91 other files. Read first to learn the vocabulary.
• internal/wire/analyze.go — Foundation: imported by 1, no internal dependencies of its own.
• internal/wire/testdata/BindInjectorArg/foo/wire.go — Built on the foundation; imported by 0 downstream files.
• internal/wire/testdata/BindInjectorArgPointer/foo/wire.go — Built on the foundation; imported by 0 downstream files.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone the repository:

git clone https://github.com/google/wire.git
cd wire

Install the wire command-line tool:

go install ./cmd/wire

Verify installation by checking the generated help:

wire -help

Daily commands:

Wire is a code generation tool, not a runtime service. To use it on a Go project:

cd your-go-project
wire ./...

This scans for wire.go files, analyzes dependencies, and generates wire_gen.go files. To run Wire's own test suite:

sh internal/runtests.sh

…shortened for this brief.

Key cautions & unknowns

• Stale — last commit 1y ago
• Scorecard: marked unmaintained (0/10)
• Wire operates at compile time and requires wire.go files with specific syntax (see testdata examples for syntax patterns). The project is unmaintained, so compatibility with Go versions beyond 1.19 is untested—verify…
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
