#Uxn

An assembler and emulator for the Uxn stack-machine, written in ANSI C.

#Download binaries

Binaries are available for 64-bit x86 computers running Linux, Windows and macOS.

#Build

#Linux/OS X

To build the Uxn emulator, you must install SDL2 for your distro. If you are using a package manager:

sudo pacman -Sy sdl2             # Arch
sudo apt install libsdl2-dev     # Ubuntu
brew install sdl2                # OS X

Build the assembler and emulator by running the build.sh script. The assembler(uxnasm) and emulator(uxnemu) are created in the /bin folder.

./build.sh 
	--debug # Add debug flags to compiler
	--format # Format source code

If you wish to build the emulator without graphics mode:

cc src/uxn.c -DNDEBUG -Os -g0 -s src/uxncli.c -o bin/uxncli

#Plan 9

To build the Uxn emulator on 9front, via npe:

mk

If the build fails on 9front because of missing headers or functions, try again after rm -r /sys/include/npe.

#Windows

Uxn can be built on Windows with MSYS2. Install by downloading from their website or with Chocolatey with choco install msys2. In the MSYS shell, type:

pacman -S git mingw-w64-x86_64-gcc mingw64/mingw-w64-x86_64-SDL2
export PATH="${PATH}:/mingw64/bin"
git clone https://git.sr.ht/~rabbits/uxn
cd uxn
./build.sh

#Getting Started

#Emulator

To launch a .rom in the emulator, point the emulator to the target rom file:

bin/uxnemu bin/piano.rom

You can also use the emulator without graphics by using uxncli. You can find additional roms here, you can find prebuilt rom files here.

#Assembler

The following command will create an Uxn-compatible rom from an uxntal file. Point the assembler to a .tal file, followed by and the rom name:

bin/uxnasm projects/examples/demos/life.tal bin/life.rom

#I/O

You can send events from Uxn to another application, or another instance of uxn, with the Unix pipe. For a companion application that translates notes data into midi, see the shim.

uxnemu orca.rom | shim
