Prettier Java Plugin
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.
A Prettier plugin must first parse the source code of the target language into a traversable data structure (Usually an Abstract Syntax Tree) and then print out that data structure in a "pretty" style.
prettier-javahas no additional runtime pre-requisites (e.g: Python executable). It could even be used inside a browser.
This project contains 2 packages:
# Local installation npm install prettier-plugin-java --save-dev
npm install -g prettier prettier-plugin-java
or with yarn:
# Local installation yarn add prettier-plugin-java --dev
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.
To reformat all your Java files, run:
# If you have installed the package locally npx prettier --write "**/*.java"
prettier --write "*/.java"
