Versions

Version 4.0 (2011) is able to run on Mac and Linux. It used two separate source trees and was therefore called "POL" on Linux systems and "POM" on Mac.

Version 5.0 Phoenicis

Version 5.0, currently under development, uses the same codebase for Mac and Linux. It has been named POL-POM-5, later POL-POM, and currently is being developed under the name Phoenicis.

Scripting language

PlayOnLinux includes advanced functions in Bash allowing the community to make scripts easily by controlling the installation process. Each supported program has its own script written in this language. For example, the simple following script will popup a setup window with the message ''Hello World'': #!/bin/bash "$PLAYONLINUX" = "" && exit 0 source "$PLAYONLINUX/lib/sources" POL_SetupWindow_Init POL_SetupWindow_message "Hello World!" "My first message" POL_SetupWindow_Close exit
