Previously Varvara did not have a way to create new directories.
This change adds that capability without adding or modifying any
device ports.
The changes are:
(1) When a filename ends in the directory separator, writing
any value to File/write will create a directory. Unlike
with regular files, the value is ignored.
(2) When writing any path (regular files or directories) if
there are missing parent directories Varvara will attempt
to create them first. This behavior is similar to mkdir -p.
The directory separator is / on most platforms, and \ on Windows.
On POSIX platforms the directories will be created with permission
0755 (modified by the user's umask value).
This change has been tested and works in both uxnemu and uxncli.

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
sudo xbps-install SDL2-devel # Void Linux
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
--install # Copy to ~/bin
If you wish to build the emulator without graphics mode:
cc src/devices/datetime.c src/devices/system.c src/devices/console.c src/devices/file.c src/uxn.c -DNDEBUG -Os -g0 -s src/uxncli.c -o bin/uxncli
Plan 9
To build and install the Uxn emulator on 9front, via npe:
mk install
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
If you'd like to work with the Console device in uxnemu.exe, run ./build.sh --console instead: this will bring up an extra window for console I/O unless you run uxnemu.exe in Command Prompt or PowerShell.
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.
