Google Styleguide Java Format for VSCode

stackoverflow.com › questions › 58697625 › google-styleguide-java-format-for-vscode

I spent some time working on this same problem yesterday. The best and most reliable solution I was able to come up with was to install google-java-format into my path and then use the RunOnSave extension to invoke the binary for files with the .java extension.

Install emeraldwalk/vscode-runonsave:

$ code --install-extension emeraldwalk.RunOnSave

Install google-java-format for your system:

# Example using Homebrew on OS X
$ brew install google-java-format

Configure RunOnSave in Visual Studio Code settings:

{
  "emeraldwalk.runonsave": {
    "commands": [
      {
        "match": "\\.java$",
        "cmd": "google-java-format --replace ${file}"
      },
    ],
  },
}

I describe more of the methodology in this blog post.

Always use curly braces around the body of an if, else, for, do or while statement, even if it’s only a single line. Follow the Kernighan and Ritchie (K&R) ‘Egyptian brackets’ style where there is no line break before the opening brace. See the braces section of the Google Java style guide for more details.

google-java-format requires Java 16.0.1 SDK. You have to install it first.

There is an extension ilkka.google-java-format on the Visual Studio Code marketplace, but it is incompatible with current version.

I have to change it this way:

Open file : C:\Documents and Settings\<USERNAME>\.vscode\extensions\ilkka.google-java-format-1.0.2\out\extension.js

Update function provideDocumentRangeFormattingEdits this way:

return new Promise((resolve, reject) => {
    let stdout = "";
    let stderr = "";
    let child = cp.spawn("java.exe",
        [
            "--add-exports", "jdk.compiler/com.sun.tools.javac.api=ALL-UNNAMED",
            "--add-exports", "jdk.compiler/com.sun.tools.javac.file=ALL-UNNAMED",
            "--add-exports", "jdk.compiler/com.sun.tools.javac.parser=ALL-UNNAMED",
            "--add-exports", "jdk.compiler/com.sun.tools.javac.tree=ALL-UNNAMED",
            "--add-exports", "jdk.compiler/com.sun.tools.javac.util=ALL-UNNAMED",
            "-jar",
            executablePath,
            "--lines",
            `${range.start.line}:${range.end.line}`,
            "-",
        ]);

In Settings -> Preferences set executablePath to path to jar archive (google-java-format-1.10.0-all-deps.jar)

Enjoy

Which Java code style should you use? - DEV Community

October 1, 2019 - If you use a build tool like Maven, there are some plug-ins like the fmt-maven-plugin to autoformat code when builds are ran (fmt-maven-plugin uses Google style). That may feel a bit extreme. You may be comfortable with just letting your IDE support this, in which case you would want to get a hold of an XML file for the code style settings that you can import into Eclipse or IntelliJ. It's really up to you. All that being said, you also probably want to grapple with how to approach Java 8+ features like lambdas and streams.
