Avian is a lightweight alternative to Java programming language.
Avian is a lightweight virtual machine and class library designed to provide a useful subset of Java's features, suitable for building self-contained applications.
Efficient
The VM is implemented from scratch and designed to be both fast and small.
· Just-In-Time (JIT) compilation for fast method execution
· Generational, copying garbage collection ensures short pause times and good spatial locality
· Thread-local heaps provide O(1) memory allocation with no synchronization overhead
· Null pointer dereferences are handled via OS signals to avoid unecessary branches
The class library is designed to be as loosely-coupled as possible, allowing tools like ProGuard to aggressively isolate the minimum code needed for an application. This translates to smaller downloads and faster startup.
Portable
Platform-specific code is hidden behind a generic interface, so adding support for new OSes is easy. Avian currently supports Linux (i386 and x86_64), Windows (i386), and OS X (i386), with more to come.
The only third-party dependency beyond OS-provided libraries is zlib, which is itself very portable. Although the VM is written in C++, it does not depend on the C++ standard library, and is thus robust in the face of ABI changes.
Embeddable
Not only can applications embed the VM, but the VM itself supports class and resource loading from embedded jar files. This means you can produce a single executable containing your entire application, thus simplifying the installation process.
Requirements:
· GNU make 3.80 or later
· GCC 3.4 or later
· JDK 1.5 or later
· GNU binutils 2.17 or later
· zlib 1.2.3 or later
Quick Start:
$ export JAVA_HOME=/usr/local/java # or wherever you have Java installed
$ make
$ build/linux-i386-compile-fast/avian -cp build/test Hello
What's New in This Release:
· This release fixes several regressions introduced in version 0.1, plus a few corner-case bugs which existed in previous releases.
