Bash completion

If you want “intelligent” bash completion on TAB for apertium, lttoolbox, vislcg3 and hfst, do e.g.:

$ git clone https://github.com/unhammer/apertium-completion.git ~/apertium-completion

and add this to your ~/.bashrc:

if ! shopt -oq posix && \
   [[ ( -z "$INSIDE_EMACS" || "$EMACS_BASH_COMPLETE" = "t" ) ]]; then
    for f in ~/apertium-completion/completions/*; do
        [[ -f $f ]] && source "$f"
    done
fi

Alternatively, if your OS sources files from e.g. /etc/bash_completion_d automatically, just sudo cp ~/apertium-completion/completions/* /etc/bash_completion_d/ (then you don’t have to add anything to ~/.bashrc).

Now open a new terminal and try typing apertium and press TAB twice, you should get a list of installed language pairs; apertium -d . and TAB twice should show you a list of the possible translation modes in this directory; etc.

PROTIP: If you add

"\e\C-d": "apertium -d . \t\t"

to ~/.inputrc you can simply type "alt+ctrl+d" and your terminal will fill out "apertium -d . " and press TAB twice (showing the list of modes of your current directory).
