neetdraw is a terminal drawing application with multiplayer support.



Regular releases are sporadic. git master should be stable enough. You can get a package with the latest development version using Arch Linuxs AUR, or as a Nix derivation.


Build dependencies: CMake, pkg-config, liberty (included), termo (included)
Runtime dependencies: ncursesw, libev

$ git clone --recursive https://git.janouch.name/p/neetdraw.git
$ mkdir neetdraw/build
$ cd neetdraw/build
$ make

To install the application, you can do either the usual:

# make install

Or you can try telling CMake to make a package for you. For Debian it is:

$ cpack -G DEB
# dpkg -i neetdraw-*.deb


For standalone mode you can run the program without arguments:

$ neetdraw

To run as a server for other clients to connect to and draw simultaneously:

$ neetdraw -s :1234

To connect to a running server, run:

$ neetdraw -c localhost:1234

Once you have the program running, simply select a colour you like from the palette and draw by pressing and dragging the mouse. Use the middle mouse button to move the canvas.

You can store the current image to drawing.bin and load it back using the s and l keys respectively. To just export the current picture for printing it on a terminal, press e. To export for IRC, press E.

Known Issues

VTE-based terminals, such as gnome-terminal, are terminally broken and you will experience drawing artefacts. Those are neither a problem of this application, nor a problem of ncurses as far as I can tell.

To achieve the best results, please use a decent terminal such as rxvt-unicode or xterm. These two are feature-full and fast. st also works great.

Even so, try not to strain the application too much. It can and will break if you flood the communication channel with the terminal.
