    QR Code generator library

    QR Code generator library

    High-quality QR Code generator library in Java, TypeScript/JavaScript

    This project aims to be the best, clearest library for generating QR Codes. My primary goals are flexible options and absolute correctness. The secondary goals are compact implementation size and good documentation comments. This work is an independent implementation based on reading the official ISO specification documents. I believe that my library has a more intuitive API and shorter code length than competing libraries out there. The library is designed first in Java and then ported to TypeScript, Python, Rust, C++, and C. It is open source under the MIT License. For each language, the codebase is roughly 1000 lines of code and has no dependencies other than the respective language’s standard library.

    Auto

    Auto

    A collection of source code generators for Java

    Auto is a collection of source code generators for Java. Java is full of code that is mechanical, repetitive, typically untested and sometimes the source of subtle bugs. Sounds like a job for robots! The Auto subprojects are a collection of code generators that automate those types of tasks. They create the code you would have written, but without the bugs. Save time. Save code. Save sanity. Some of Auto subprojects are AutoFactory, JSR-330-compatible factories, AutoService, provider-configuration files for ServiceLoader, AutoValue, immutable value-type code generation for Java 7+, and Common, helper utilities for writing annotation processors. Auto is licensed under the Apache License, Version 2.0.
