eufon

Broken, not ready for use

euphony: noun Harmonious arrangement of sounds in composition; a smooth and agreeable combination of articulate elements in any piece of writing.

A mostly Fennel-based graphical environment tailored for Linux-based mobile devices. The principles we aspire to are

• "habitable software" - build the system in such a way that a technically competent user may change it to serve their needs, potentially even in ways that weren't anticipated in the original design. Emacs has this quality.

• optimised for touchscreens. My phone has no hardware keyboard and few hardware buttons, let's play to its strengths instead of compensating for its weaknesses

As of 2022 these principles are more aspirational than actual. This repo is basically in an advanced state of brokenness

Running the shell/apps locally

$ nix-shell
nix-shell$ kiwmi -c init.lua 

This works on desktop or on mobile - Kiwmi is built on wlroots, which will open a window on your existing Wayland or X11 desktop if you're running one.

If you're connected over ssh and want to run Kiwmi on the console, further contortions are required as you don't have the permissions by default: run this before attempting to start Kiwmi

 nix-shell -p seatd --run "sudo -b seatd -u $USER"

Connecting to the repl

By default Eufon opens a Unix socket to which you can connect to interact with a Fennel REPL. The eufonctl script is a wrapper around socat

$ eufonctl $WAYLAND_DISPLAY

Building for a device

Eufon can be installed as a Mobile NixOS module, by adding module.nix to the imports in your configuration.nix. For example, on my development phone I have

  imports = [
    (import <mobile-nixos/lib/configuration.nix> {
      device = "motorola-potter";
    })
    /home/dan/src/phoen/eufon/module.nix
  ];

Instructions for using Mobile NixOS are currently outside the scope of this README.
