This project provides a template for creating bash completion scripts that support nested command namespaces.

Copy the template.bash file and replace {{bc_namespace}}, {{bc_executable}} and {{bc_command}}. Add your changes above the # completion function line so that the scripts for importing from and updating the template works correctly.

touch ~/rtorrent-docker/misc/rtorrent-docker.bash
/update rtorrent_docker rt_do "rt-do rt-do.exe" ~/rtorrent-docker/misc/rtorrent-docker.bash 

Update your file with the latest changes to template.bash.

./import ~/rtorrent-docker/misc/rtorrent-docker.bash

Update template.bash with changes made to your file below the # completion function line.

{{bc_namespace}} # all bash functions are prepended with "_{{bc_namespace}}_"
{{bc_executable}} # the filename of the executable binary
{{bc_command}} # the bash-friendly name appended to the namespace

# arg_funcs+=(--foo##skip)
# arg_funcs+=(--foo#_bazspace__skip)
# arg_funcs+=(--foo##compgen#-o#default)

Adds a handler for the flag --foo so it calls _bazspace__skip, with ## adding the namespace prefix and subsequent # adding arguments.
