Open Source Java Libraries for Linux

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.

Java HTML/XML Compressor is a very small, fast and easy to use library that compresses given HTML or XML source by removing extra whitespaces, comments and other unneeded characters without breaking the content structure.

Provides a Java programmable only text file editor. No gui is available. It supplies most of the features you expect from an editor including selections.

JFling provides tools for (un)marshalling fixed length string data to and from java objects with typed properties. It's codegenerator uses plain csv files to generate fixed-length-string wrapper classes. (see our wiki 'Hosted Apps/Trac' for more info)

Use of annotations to specify constraints on methods. There are annotations available to perform common checks (i.e. a parameter has to be not null, an int value has to be positive, etc.) and to use a full-flavoured design by contract in java with suppor

this is a small JSP tag library which allows you to create PDF documents within your JSPs. All you need to do is add the jar file to your lib folder under WEB-INF and the tld file in a tld folder under WEB-INF and you are ready to use the tags.

ULS is a class library for creating lexical analyzer from language specification file. It's provided as C/C++/C# and Java (class) libraries with a few of tools on Linux/Windows platform.

Java to C++ porting framework

Lightweight Java library for building MDX queries.

ooc is an object-oriented programming language which is implemented with a source-to-source translator to pure C99. It supports classes, abstract functions, foreach, ranges, etc. It intends to be modern, modular, extensible, yet simple and fast.
