Mastfrog Libraries on Maven Central

Home to a set of open source Java libraries developed by Tim Boudreau over many years, all available from Maven Central under the group id com.mastfrog including frameworks and utilities such as:

Frameworks

• Acteur — A Netty-based framework with NodeJS-like semantics and a Guice-based, extensible logic pipeline that allows small chunks of application logic to be written reusably and combined in ad-hoc ways. Extension libraries support MongoDB, JDBC, JSON-based logging, and much more. · source · javadoc
• Giulius — Utilities for simplifying and standardizing working with Guice and loading application settings, plus Guice modules that integrate JDBC, MongoDB, Etcd, and more. · source · javadoc
• Scamper — A framework for writing SCTP protocols, clients and servers. · source · javadoc
• Annotation Tools — A toolkit for writing Java annotation processors - without having any dependency on the annotation classes being processed, and for validating those annotations before doing any other processing, and processing annotations in a deterministic order - the javac API for doing this sort of thing - particularly referencing types without trying (and failing) to load them into javac's JVM is excruciating. This library makes it trivial. · source · javadoc
• Bunyan-Java — A port of the NodeJS bunyan JSON-based logging library to Java - machine readable, standardized logging for the modern world. Includes wrappers for common logging frameworks. · source · javadoc
• Portable Crypto — Java and NodeJS libraries that implement for interoperable AES128 and Blowfish encryption, signing and MACs, as wrappers around the JDK and Node's built in cryptography support - getting these things to actually generate output the other considers valid is harder than it ought to be. · source · javadoc

Testing

• Giulius Tests — A JUnit 4 test runner supporting test methods with parameters injected by Guice, and iterative running of the same test class or method against multiple Guice modules to test multiple implementations bound by those modules. · source · javadoc
• Blather — Easily write asynchronous tests of websocket servers. · source · javadoc
• Netty Http Test Harness — Easily write unit tests that make asynchronous HTTP calls. · source · javadoc

Libraries and Mini-Frameworks

• Bits — A drop-in replacement for java.util.BitSet with read-only and read-write interfaces, support for bit sets larger than Integer.MAX_VALUE, with backing store implementations that include off-heap memory and memory-mapped files in addition to Java long arrays. · source · javadoc
• Graph — Uses the Bits library to implement high-performance, micro-memory-footprint directed graphs, with built-in implementations of PageRank and other algorithms. · source · javadoc
• Range — Interfaces for working reliably with collections of ranges (integer or long) - a common and death-by-off-by-one-errors prone problem in everything from time-series manipulation, to code completion, to memory management. · source · javadoc
• Function — Mirror interfaces for those in java.util.function that can throw exceptions, plus some missing supplier and predicate interfaces. · source · javadoc
