Implement screencast as a transient singleton systemd service. The service's main process can run ffmpeg (as a background process?), and on receiving SIGUSR1, finish up.

declarative home directory setup

systemd.tmpfiles.rules = [
    "d ${config.users.users.ivan.home}/Documents 0755 :ivan :users -"
    "d ${config.users.users.ivan.home}/Pictures 0755 :ivan :users -"
    "d ${config.users.users.ivan.home}/Music 0755 :ivan :users -"
  ];
# FIXME: only if value.isNormalUser && value.createHome
systemd.tmpfiles.settings =
  lib.mapAttrs' (name: value:
    let
      home = value.home;
      fields = { mode = "0755"; user = ":${name}"; group = ":users"; age = "-"; };
    in lib.nameValuePair "10-home-${name}-subdirs" {
      "${home}/Documents" = { d = fields; };
      "${home}/Pictures" = { d = fields; };
      "${home}/Music" = { d = fields; };
    };
  ) (lib.filterAttrs (name: value: value.isNormalUser && value.createHome) config.users.users);

xmonad

  • look into xmonad/xmonad-contrib#878 (comment)
  • look into xmonad-contrib/XMonad/Actions/CopyWindow.hs
  • look into X.A.TopicSpace and X.H.WorkspaceHistory
  • workspace metadata :: [ScopeName]
    • a tmux-like session is a Scope, and the workspaces available to that Scope are determined by the workspaces' metadata
    • workspace prompt to associate a specified workspace with the current scope and position it within the current scope's workspace sort order according to a given function
      • this could be composed with additional behavior to swap the specified workspace in at the position of the currently active workspace, and dissassociate the current workspace from the current scope
  • dynamic workspaces (to behave like tmux sessions)?
  • prompt for directory and session-name to launch alacritty with diss running nvim
  • key to grab the 2nd line from a pass entry
