### Linux
To build the Uxn emulator, you must have [SDL2](https://wiki.libsdl.org/).
To build the Uxn emulator, you must install [SDL2](https://wiki.libsdl.org/) for your distro. For example:
```sh
sudo pacman -Sy sdl2 # Arch
sudo apt install libsdl2-dev # Ubuntu
```
Build the assembler and emulator by running the `build.sh` script. The assembler(`uxnasm`) and emulator(`uxnemu`) are created in the `/bin` folder.
```sh
./build.sh
--debug # Add debug flags to compiler
```
If you only wish to simply build the `uxncli` cli tool:
```sh
cc src/uxn.c -DNDEBUG -Os -g0 -s src/uxncli.c -o bin/uxncli
```

## 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.
### Emulator
To launch a `.rom` in the emulator, point the emulator to the target rom file:
```sh
bin/uxnemu bin/piano.rom
```
./build.sh
```
You can also use the emulator without graphics by using `uxncli`. You can find additional roms [here](https://sr.ht/~rabbits/uxn/sources), you can find prebuilt rom files [here](https://itch.io/c/248074/uxn-roms).
### Assembler
The following command will create an Uxn-compatible rom from an [uxntal file](https://wiki.xxiivv.com/site/uxntal.html). Point the assembler to a .tal file in `/projects` to assemble a rom.
The following command will create an Uxn-compatible rom from an [uxntal file](https://wiki.xxiivv.com/site/uxntal.html). Point the assembler to a `.tal` file, followed by and the rom name:
```
```sh
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). If you only wish to build `uxncli`
```
cc src/uxn.c -DNDEBUG -Os -g0 -s src/uxncli.c -o bin/uxncli
```
### 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).
```
```sh
uxnemu orca.rom | shim
```
