Tab Completion for Dhiraagu WebSMS Script

A LONNNNG LOONG time ago (two years specifically) I wrote a bash script that would allow me to send websms's on the command line.

This script has been working perfectly for me since the day I wrote it. However, the problem was that my "directory" file had started to grow a little out of proportion, and I started having trouble remembering all the aliases I put in it. So I wanted to enable custom tab completions on the script.

Enter this tiny bit of code.
All you have to do is insert the following at the end of your bashrc file (usually in ~/.bashrc)

complete -F _bdwsmscomplete websms
_bdwsmscomplete()
{
 local CUR PRE OPTS CONTACTS
 local WSMSDIR="$HOME/.wsmsdir" #change accordingly
     CUR="${COMP_WORDS[COMP_CWORD]}"
 PRE="${COMP_WORDS[COMP_CWORD-1]}"
 OPTS="-h -v -s -d -u -p -n"
 CONTACTS="$(cut -f1 -d',' ${WSMSDIR})"
 
 if [[ ${CUR} = -* ]]
 then
  COMPREPLY=($(compgen -W "${OPTS}" -- ${CUR}))
  return 0
 fi
   
 case ${PRE} in 
  -n)
   COMPREPLY=($(compgen -W "${CONTACTS}" -- ${CUR}))
   return 0
   ;;
  websms*) 
   COMPREPLY=($(compgen -W "-n" -- ${CUR}))
   return 0
   ;;
 esac

 return 0
}

If everything went well, you should be able to hit the [TAB] key while at the -n option and it'll automatically try to fill in the name of your contact.Enjoy!

P.S You'll need to re-open the terminal.
