Lukyt
Lukyt is a JVM made in Lua supporting Java 1.2. It's main advantage is to currently have a very small startup time and overhead.
Features:
- While loops (technically should work)
- For loops
- Native support (integration from Lua side)
-
Standard library (will prob move to GNU Classpath)
- System.out
- Some system methods
- Basic PrintStreams
-
Lua integration (from Java side)
- OS class
- Full int/short/byte/char math
- Full float math
- Full long/double math
- Classes
- Interfaces
- Throwables
- JIT
How to use?
The JVM itself can be used by any program and is independent from the command-line program.
The command line program allows to execute classes.
You can print an help message with lua lukyt.lua --help
To launch the HelloWorld test, you can do:
lua lukyt.lua --classpath=test HelloWorld
which will give the same result as:
java -cp test HelloWorld
You'll notice Lukyt seemingly takes less time to execute the HelloWorld program. This is because all the overhead of the JVM are not required on a program that small. So on small programs, Lukyt's small overhead and interpreter are able to execute the program fastly.
