Uxn11

An emulator for the Uxn stack-machine, written in ANSI C. The emulator contains a few linux specific utilities in the Console device to allow for it to interface with the unix systems.

Building

Makefile

For your convenience a Makefile is provided. You can run make install to build and install the files.

By default, files are installed into ~/.local but this can be overridden using PREFIX:

# installs files into ~/.local/bin and ~/.local/share
$ make install

# installs files into /opt/uxn/bin and /opt/uxn/share
$ make PREFIX=/opt/uxn install

Graphical

All you need is X11.

gcc -Os -DNDEBUG -g0 -s src/uxn.c src/devices/system.c src/devices/console.c src/devices/screen.c src/devices/controller.c src/devices/mouse.c src/devices/file.c src/devices/datetime.c src/uxn11.c -o bin/uxn11 -lX11

Terminal

If you wish to build the emulator without graphics mode:

gcc -Os -DNDEBUG -g0 -s src/uxn.c src/devices/system.c src/devices/console.c src/devices/file.c src/devices/datetime.c src/uxncli.c -o bin/uxncli

If do not wish to build it yourself, you can download linux binaries for uxnasm, uxncli and uxn11.

Usage

The first parameter is the rom file, the subsequent arguments will be accessible to the rom, via the Console vector.

bin/uxnemu bin/polycat.rom arg1 arg2

Manual

A manual page is provided documenting the Uxntal language:

man ./doc/man/uxntal.7

After running make install the man page should be found by man uxntal.
