Project Modules

There are no modules declared in this project.

google-java-format

google-java-format is a program that reformats Java source code to comply with Google Java Style.

Using the formatter

from the command-line

Download the formatter and run it with:

java -jar /path/to/google-java-format-1.9-all-deps.jar <options> [files...]

The formatter can act on whole files, on limited lines (--lines), on specific offsets (--offset), passing through to standard-out (default) or altered in-place (--replace).

To reformat changed lines in a specific patch, use google-java-format-diff.py.

Note: There is no configurability as to the formatter's algorithm for formatting. This is a deliberate design decision to unify our code formatting on a single format.

IntelliJ, Android Studio, and other JetBrains IDEs

A google-java-format IntelliJ plugin is available from the plugin repository. To install it, go to your IDE's settings and select the Plugins category. Click the Marketplace tab, search for the google-java-format plugin, and click the Install button.

The plugin will be disabled by default. To enable it in the current project, go to File→Settings...→google-java-format Settings (or IntelliJ IDEA→Preferences...→Other Settings→google-java-format Settings on macOS) and check the Enable google-java-format checkbox. (A notification will be presented when you first open a project offering to do this for you.)

To enable it by default in new projects, use File→Other Settings→Default Settings....

When enabled, it will replace the normal Reformat Code action, which can be triggered from the Code menu or with the Ctrl-Alt-L (by default) keyboard shortcut.

The import ordering is not handled by this plugin, unfortunately. To fix the import order, download the IntelliJ Java Google Style file and import it into File→Settings→Editor→Code Style.

Eclipse

Version 1.6 of the google-java-format Eclipse plugin can be downloaded from the releases page. Drop it into the Eclipse drop-ins folder to activate the plugin.

The plugin adds a google-java-format formatter implementation that can be configured in Window > Preferences > Java > Code Style > Formatter > Formatter Implementation.

Third-party integrations

as a library

The formatter can be used in software which generates java to output more legible java code. Just include the library in your maven/gradle/etc. configuration.

Maven

<dependency>
  <groupId>com.google.googlejavaformat</groupId>
  <artifactId>google-java-format</artifactId>
  <version>1.9</version>
</dependency>

Gradle

dependencies {
  compile 'com.google.googlejavaformat:google-java-format:1.9'
}

You can then use the formatter through the formatSource methods. E.g.

String formattedSource = new Formatter().formatSource(sourceString);

or

CharSource source = ...
CharSink output = ...
new Formatter().formatSource(source, output);

Your starting point should be the instance methods of com.google.googlejavaformat.java.Formatter.

Building from source

mvn install
