ZX5-Kotlin is a multi-thread implementation of the ZX5 data compressor in Kotlin.
To run this compressor, you must have installed Java 8 or later.
To compress a file such as "Cobra.scr", use the command-line compressor as follows:
java -jar zx5.jar Cobra.scr
Java 8 memory allocation is limited to (at most) 1Gb by default. You can use parameter "-Xmx" to increase maximum memory allocation, for instance:
java -Xmx2G -jar zx5.jar Cobra.scr
This compressor uses 16 threads by default. You can use parameter "-p" to specify a different number of threads, for instance:
java -jar zx5.jar -p4 Cobra.scr
All other parameters work exactly like the original version. Check the official ZX5 page for further details.
The Kotlin implementation of ZX5 was authored by Einar Saukas and it's available under the "BSD-3" license.
