Prettier Java

How it works

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.

Status

• Parser package alpha version done.
• Now Investigating the re-printer (actually prettier-java package)

Road map to Alpha

• Parser Package:

  • POC: optimized backtracking to handle Java Grammar non LL(k) nature.
  • Milestone 1 - Success parsing "Java Design Patterns" repo.
  • Milestone 2 - Success parsing "spring-boot" repo.
  • Investigate performance optimizations.
  • Release Alpha version to npm. - https://www.npmjs.com/package/java-parser

• prettier-java package

  • POC: Prettier "Re-writer" based on a Chevrotain CST instead of an AST.
  • Milestone 1 - Success cyclic rewriting "Java Design Patterns" repo.
  • Milestone 2 - Success parsing "spring-boot" repo.
