How to use

  1. Merge the following part definition into your Snapcraft recipe:

    parts:
  # The ncurses-launch launcher: Fix ncurses applications in the snap runtime - doc - snapcraft.io
  # https://forum.snapcraft.io/t/the-ncurses-launch-launcher-fix-ncurses-applications-in-the-snap-runtime/10444
  ncurses-launch:
    source: https://github.com/Lin-Buo-Ren/ncurses-launch.git
    source-tag: v1.0.0
    stage-packages:
      - ncurses-base
    plugin: dump

  2. In the apps stanza, insert bin/ncurses-launch into the command chain:

    apps:
  _app_name_:
    # The command to run the application, the value should be a *relative path* to an executable file rooted from the `prime` directory
    command: bin/ncurses-launch "${SNAP}"/bin/_app_command_

    if you’re using the full adapter:

    apps:
  _app_name_:
    # The environment adapter style to use, `command-chain` is only supported
    adapter: full

    # The command to run the application, the value should be a *relative path* to an executable file rooted from the `prime` directory
    command: bin/_app_command_
    command-chain:
    - bin/ncurses-launch
