# If you define an alias (e.g. "t") to todo.sh, you need to explicitly enable
# completion for it, too:
#complete -F _todo t
# It is recommended to put this line next to your alias definition in your
# ~/.bashrc (or wherever else you're defining your alias). If you simply
# uncomment it here, you will need to redo this on every todo.txt update!
# If you have renamed the todo.sh executable, or if it is not accessible through
# PATH, you need to add and use a wrapper completion function, like this:
#_todoElsewhere()
#{
# local _todo_sh='/path/to/todo2.sh'
# _todo "$@"
#}
#complete -F _todoElsewhere /path/to/todo2.sh
# If you use aliases to use different configuration(s), you need to add and use
# a wrapper completion function for each configuration if you want to complete
# fron the actual configured task locations:
#alias todo2='todo.sh -d "$HOME/todo2.cfg"'
#_todo2()
#{
# local _todo_sh='todo.sh -d "$HOME/todo2.cfg"'
# _todo "$@"
#}
#complete -F _todo2 todo2
