About

Black Box is a native terminal emulator for GNOME that offers superb theming options.

With Black Box you can:

  • Set colors schemes and integrate them with the rest of the window
  • Customize font and size
  • Customize keyboard shortcuts
  • Render Sixel escape sequences
  • Fully hide the window headerbar
  • Quickly open links and files by ctrl+clicking file paths and URLs
  • Easily paste file paths by dragging them into the window

This app is written in Vala and uses GTK 4, libadwaita, and VTE.

Permissions

4 permissions weaken the sandbox. Flatsonar asks before installing.

  • all devices (/dev): webcams, disks, raw hardware
    --device=all
  • full access to your entire file system
    --filesystem=host
  • sandbox escape: can run commands on the host via flatpak-spawn
    --talk-name=org.freedesktop.Flatpak
  • X11 display: X11 lets apps read input and windows of other apps
    --socket=x11
  • inter-process communication (needed for X11)
    --share=ipc
  • Wayland display
    --socket=wayland
  • X11 display, only when Wayland is unavailable
    --socket=fallback-x11
