When marchyo.desktop.enable = true, the marchyo.defaults.* options control which applications are installed and registered as system defaults. Set any option to null to skip management for that category.

Options

OptionDefaultChoices
marchyo.defaults.browser"google-chrome""brave", "google-chrome", "firefox", "chromium"
marchyo.defaults.editor"jotain""emacs", "jotain", "vscode", "vscodium", "zed"
marchyo.defaults.terminalEditor"jotain""emacs", "jotain", "neovim", "helix", "nano"
marchyo.defaults.videoPlayer"mpv""mpv", "vlc", "celluloid"
marchyo.defaults.audioPlayer"mpv""mpv", "vlc", "amberol"
marchyo.defaults.musicPlayer"spotify""spotify"
marchyo.defaults.fileManager"nautilus""nautilus", "thunar"
marchyo.defaults.terminalFileManager"yazi""yazi", "ranger", "lf"
marchyo.defaults.imageEditor"pinta""pinta", "gimp", "krita"
marchyo.defaults.email"gmail""gmail", "thunderbird", "outlook"

​
Example

marchyo.defaults = {
  browser = "firefox";
  editor = "vscode";
  terminalEditor = "neovim";
  videoPlayer = "mpv";
  audioPlayer = "mpv";
  musicPlayer = "spotify";
  fileManager = "nautilus";
  terminalFileManager = "yazi";
  imageEditor = "gimp";
  email = "thunderbird";
};

​
Skipping management

Set any option to null to prevent Marchyo from installing or configuring that category: 
marchyo.defaults = {
  browser = null;        # Don't manage browser
  musicPlayer = null;    # Don't install a music player
};

​
Externally managed applications

Some choices are “externally managed” — Marchyo does not install a package for them:
  • "jotain" (editor/terminalEditor) — Package installation and $EDITOR/$VISUAL are handled by programs.jotain outside of Marchyo.
  • "gmail" and "outlook" (email) — Web applications opened in the default browser. No package is installed.

​
How defaults work

When a default is set, Marchyo:
  1. Installs the package (unless externally managed)
  2. Registers MIME type associations — e.g., setting browser = "firefox" registers Firefox as the handler for text/html, x-scheme-handler/http, etc.
  3. Sets environment variables — e.g., editor sets $VISUAL, terminalEditor sets $EDITOR
