Prettier Java Plugin

readme

Prettier Java

Intro

Prettier is an opinionated code formatter. It enforces a consistent style by parsing your code and re-printing it with its own rules that take the maximum line length into account, wrapping code when necessary.

How it works

A Prettier plugin must first parse the source code of the target language into a traversable data structure (Usually an A*bstract *Syntax Tree) and then print out that data structure in a "pretty" style.

Prettier-Java uses a Java-Parser implemented in JavaScript using the Chevrotain Parser Building Toolkit for JavaScript. What this means is that unlike many other Prettier plugins, prettier-java has no additional runtime pre-requisites (e.g: Python executable). It could even be used inside a browser.

Subpackages

This project contains 2 packages:

prettier-plugin-java A plugin for Prettier to format Java code
java-parser A Java Parser using Chevrotain which output a C*oncrete *Syntax Tree

Install

Pre-requirements

Node version 10+
Prettier

Install Prettier and Prettier-Java plugin

# Local installation
npm install prettier-plugin-java --save-dev

# Or globally
npm install -g prettier prettier-plugin-java

or with yarn:

# Local installation
yarn add prettier-plugin-java --dev

# Or globally
yarn global add prettier prettier-plugin-java

Note: If you want to install the prettier-plugin-java globally, you should also install the prettier package globally.

Usage

To reformat all your Java files, you first need to create .prettierrc.yaml with following content:

plugins:
  - prettier-plugin-java

Then run:

# If you have installed the package locally
npx prettier --write "**/*.java"

# Or globally
prettier --write "**/*.java"

To see IDE configuration or other advanced usage: please go to the Advanced Usage section

Maven plugin

A neat maven plugin for prettier-java was made by developers from HubSpot. \ Add it to the plugins section of your build configuration

<build>
  <plugins>
    <plugin>
      <groupId>com.hubspot.maven.plugins</groupId>
        <artifactId>prettier-maven-plugin</artifactId>
        <!-- Find the latest version at https://github.com/jhipster/prettier-java/releases -->
        <version>0.8</version>
    </plugin>
  </plugins>
</build>

If you would like to use this plugin, we recommend you to check their project as is it well documented.

Organize imports

Prettier-java is currently sorting imports according to the Google Java Style guide.

If you are using an IDE such as IntelliJ, you might want to configure it to match with Prettier-java.

For IntelliJ, you can use this configuration: IntelliJ config

You can also import the Checkstyle configuration provided in the next section.

For VSCode with Language Support for Java, you can use this configuration (settings.json):

{
  "java.completion.importOrder": ["#"]
}

Checkstyle configuration

You can use Prettier in combination with other linter, like Checkstyle.

Here is one Checkstyle Prettier compatible configuration you can use to start with !

You can directly import the config into IntelliJ Idea for instance:

Import Checkstyle configuration

Indent configuration

In .prettierrc.yaml, you can configure the indent:

For using four spaces:

tabWidth: 4

For more configuration options such as using tabs, maximum line length, and more see https://prettier.io/docs/en/configuration.html.

Contributions are very welcome. See the contribution guide to get started. And the Help Wanted issues.

Credits

Special thanks to @thorbenvh8 for creating the original prettier-java plugin and the associated Java Parser implemented in JavaScript.

We would also like to thank the Chevrotain and Prettier contributors which made this possible.

  ANOTHER_ENUM,
  LAST_ENUM
}

when the following is kept as it is:

public enum Enum {
  THIS_IS_GOOD("abc"), THIS_IS_FINE("abc");
  public static final String thisWillBeDeleted = "DELETED";

  private final String value;

  public Enum(String value) {
    this.value = value;

Organise imports according to Google style (#273 and #281)

package my.own.pkg;

import static abc.def;
import static abc.def.Another;
import static abc.def.Something;
import static java.utils.*;
import static something.Different;

import abc.def;
import abc.def.Another;
import abc.def.Something;
import java.utils.*;
import one.last;
import something.Different;

public class PackageAndImports {}

is transformed in:

package my.own.pkg;

import static abc.def;
import static abc.def.Another;
import static abc.def.Something;
import static java.utils.*;
import static something.Different;

import abc.def;
import abc.def.Another;
import abc.def.Something;
import java.utils.*;
import one.last;
import something.Different;

public class PackageAndImports {}

Better display of local variable declarations (#283)

  @Nullable final BackupStatus lastStatus = value;

  final BackupStatus lastStatus = value;

  @Nullable BackupStatus lastStatus = value;

public boolean localVariableDeclarationWhichBreak() {

Improve binary operations indentation (#255):

Improve return statement rendering (#255)
