ivankra/anki repository overview

# Anki docker container with fcitx5 IME support.
#
# Anki version in debian repos is too old, besides it could really benefit
# from containerization when using third party addons.
#
# Prereqs:
#   * docker or better yet podman
#   * x11docker
#   * `apt-get install nxagent xclip` for some features
#   * `echo software >~/.local/share/Anki2/gldriver6` maybe to fix some rendering issues
#   * `podman build -f Dockerfile -t anki`
#
# Sample run command:
# x11docker \
#   --backend=podman \
#   --nxagent \
#   --pulseaudio \
#   --lang=en_US.UTF-8 \
#   --clipboard \
#   --hostdbus \
#   --network \
#   -- \
#   --cap-add=sys_chroot \
#   --shm-size=1g \
#   --tmpfs="$HOME/.cache" \
#   --volume="$HOME/.config/fcitx5:$HOME/.config/fcitx5:ro" \
#   --volume="$HOME/.local/share/Anki2:$HOME/.local/share/Anki2:rw" \
#   anki
