Prettier for java

December 11, 2024 by walter

Overview

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-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.
