# Auto

[![Build Status](https://github.com/google/auto/actions/workflows/ci.yml/badge.svg)](https://github.com/google/auto/actions/workflows/ci.yml)

A collection of source code generators for [Java][java].

## Overview

[Java][java] is full of code that is mechanical, repetitive, typically untested
and sometimes the source of subtle bugs. *Sounds like a job for robots!*

The Auto subprojects are a collection of code generators that automate those
types of tasks. They create the code you would have written, but without the
bugs.

Save time. Save code. Save sanity.

## Subprojects

*   [AutoFactory] - JSR-330-compatible factories

    [![Maven Central](https://img.shields.io/maven-central/v/com.google.auto.factory/auto-factory.svg)](https://mvnrepository.com/artifact/com.google.auto.factory/auto-factory)

*   [AutoService] - Provider-configuration files for [`ServiceLoader`]

    [![Maven Central](https://img.shields.io/maven-central/v/com.google.auto.service/auto-service.svg)](https://mvnrepository.com/artifact/com.google.auto.service/auto-service)

*   [AutoValue] - Immutable [value-type] code generation for Java 8+.

    [![Maven Central](https://img.shields.io/maven-central/v/com.google.auto.value/auto-value.svg)](https://mvnrepository.com/artifact/com.google.auto.value/auto-value)

*   [Common] - Helper utilities for writing annotation processors.
