Release version: 0.1-alpha Snapshot version: 0.1-SNAPSHOT

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

First download the formatter and save it where you wish. Then simply run it via:

java -jar /path/to/google-java-format-0.1-alpha.jar <options> [files...]

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

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.

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.

<dependency>
  <groupId>com.google.googlejavaformat</groupId>
  <artifactId>google-java-format</artifactId>
  <version>0.1-alpha</version>
</dependency>

dependencies {
  compile 'com.google.googlejavaformat:google-java-format:0.1-alpha'
}

You can then use the formatter quite simply using the various formatSource methods. E.g.

String formattedSource = Formatter.formatSource(sourceString);

or

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

Generally speaking, your starting point should be the static methods found in com.google.googlejavaformat.java.Formatter.

To build google-java-format from source, you will need copy IntelliJ's platform JARs from a local IntelliJ install; see install-idea-jars.sh. Alternatively, you can skip building the IntelliJ plugin:

mvn -pl '!idea_plugin' install
