# Uxn An assembler and emulator for the [Uxn stack-machine](https://wiki.xxiivv.com/site/uxn.html), written in ANSI C. ## Build ### Linux To build the Uxn emulator, you must have [SDL2](https://wiki.libsdl.org/). ```sh ./build.sh --debug # Add debug flags to compiler ``` ### Plan 9 To build the Uxn emulator on [9front](http://9front.org/), via [npe](https://git.sr.ht/~ft/npe): ```rc mk ``` If the build fails on 9front because of missing headers or functions, try again after `rm -r /sys/include/npe`. ## Getting Started Begin by building the assembler and emulator by running the build script. The assembler(`uxnasm`) and emulator(`uxnemu`) are created in the `/bin` folder. ``` ./build.sh ``` ### Assembler The following command will create an Uxn-compatible rom from an [uxntal file](https://wiki.xxiivv.com/site/uxntal.html), point to a different .tal file in `/projects` to assemble a different rom. ``` bin/uxnasm projects/examples/demos/life.tal bin/life.rom ``` ### Emulator To start the rom, point the emulator to the newly created rom: ``` bin/uxnemu bin/life.rom ``` You can also use the emulator without graphics by using `uxncli`. You can find additional roms [here](https://sr.ht/~rabbits/uxn/sources). ### 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](https://git.sr.ht/~rabbits/shim). ``` uxnemu orca.rom | shim ``` ## Emulator Controls - `F1` toggle zoom - `F2` toggle debug - `F3` capture screen ## Need a hand?
