Stack Based Virtual Machine

Building the VM Script:

GNU m4 is required to generate the VM console script. A makefile is also included that provides the recipe to compile the VM script.

Examples

See stackvm-xonotic/examples, for example programs. To test the program included in the example folder, do the following:

• Make sure the xSVM program is loaded, do this by executing stackvm.cfg.
• Execute the program to run, in this example do "exec stackvm-xonotic/examples/main.cfg" to load main.cfg
• Use the "vm.run" alias to initiate program execution.

About programs in examples folder

• math.cfg: Primitive math library containing basic functions.
• main.cfg: Example program that tests math.cfg functionality.
