Convenience Tools

Tools can make work easier and efficient.

Bash Navigation Tool

This tool allows you to quickly get to your ZP source tree. It has filename completion:

export zpdefault=Ceph

if [ -z $zpbase ]; then
   if [ -d /z ]; then
      zpbase="/z"
   elif [ -d /mnt/src/zenpacks ]; then
      zpbase="/mnt/src/zenpacks"
   elif [ -d /home/zenoss/src/europa/src/zenpacks ]; then
      zpbase="/home/zenoss/src/europa/src/zenpacks"
   elif [ -d /zenpacks ]; then
      zpbase="/zenpacks"
   elif [ -d /data/zp ]; then
      zpbase="/data/zp"
   else
      zpbase="/tmp"
   fi

   export zpbase
fi

zp()
{
   # --------------------------------------------------------------------------
   # Setup up variables..
   # --------------------------------------------------------------------------
   if [[ -z "$zpdefault" ]]; then
      export zpdefault=PythonCollector
   fi

   if [[ -z "$zplast" && -z "$zpcurrent" ]]; then
      export zplast
      export zpcurrent
   fi

         echo "zenpack exists";
         cd "$zpbase"/"$1";
         return;
      fi;
      if [[ "$1" == "-" ]]; then

         if [[ -n "$zplast" && -n "$zpcurrent" ]]; then
            echo "returning to prior zenpack";
            zptemp=$zplast
            zplast=$zpcurrent
            zpcurrent=$zptemp
            cd "$zpcurrent"
         fi
         return;
      fi;
      second="ZenPacks.zenoss.$1";
      third=${second//./\/};
      final="$zpbase"/"$second"/"$third"/;

      if [ -d $final ]; then
         echo "zenpack exists";
         zplast="$PWD";
         zpcurrent="$final";
         cd "$final";
      else
         echo "no such Zenpack $final";
         return;
      fi;
   else
      echo "Using default zp";
      zp $zpdefault;
   fi
}


function _zp()
{
   local cmd="${1##*/}"
   local word=${COMP_WORDS[COMP_CWORD]}
   # Pointer to current completion word.
   # By convention, it's named "cur" but this isn't strictly necessary.

   words=""
   case "$word" in
   *)
      for i in $zpbase/ZenPacks.zenoss.${word}*; do
         if [[ -d $i ]]; then
            words+="${i##*.}"
            words+=" "
         fi
      done
   esac

   COMPREPLY=()   # Array variable storing the possible completions.
   COMPREPLY=( $( compgen -W "$words" -- $cur ) )
}

complete -o filenames -F _zp zp

To use it, put the contents into a zp.sh file and source it from your .bashrc and then use it as follows:

zp Py<tab>

It should complete the name to PythonCollector, assuming you have the PythonCollector ZenPack installed, and take you to the folder:

$zpbase/ZenPacks.zenoss.PythonCollector/ZenPacks/zenoss/PythonCollector/

Make sure your ZenPacks are stored in one of the following directories:

• /z
• /mnt/src/zenpacks
• /home/zenoss/src/europa/src/zenpacks
• /zenpacks
• /data/zp
• /tmp
