This tip was inspired by a tip on [[Using bash completion with ctags and Vim|using bash completion with ctags]].

This implementation is significantly simpler but gets the basic job done. The only downside that I see is that it does not work in concert with the other Vim completions for zsh. For example, if you type '<code>vim -o somefile.sh -t</code>' then press the Tab key, it will not provide completions. It must be '<code>vim -t</code>' then Tab to work.

==Completing ctags with ZSH==
Add the following to your ~/.zshrc file:
<pre>
#vim tags
function _get_tags {
  [ -f ./tags ] || return
  local cur
  read -l cur
  echo $(echo $(awk -v ORS=" "  "/^${cur}/ { print \$1 }" tags))
}
compctl -x 'C[-1,-t]' -K _get_tags -- vim
#end vim tags
</pre>

Then start a new shell or source your rc file:
<pre>
source ~/.zshrc
</pre>

==What it does==
Once you start a new shell or source your rc file, you can do
<pre>
~$ vim -t MyC<tab key>
</pre>
and it will auto-complete the tag the same way it does for files and directories:
<pre>
MyClass MyClassFactory
~$ vim -t MyC
</pre>
I find this really useful when I'm jumping into a quick bug fix.

* Cool!
How would I do this using the new compsys (compdef?) instead of the old compctl?
* It didn't work for me. The problem was that "$cur" was being populated with "vim -t", which most likely would not match anything in the tags file. I used the following,
 #vim tags<br>
 function _get_tags {<br>
   [ -f ./tags ] || return<br>
   local cur<br>
   read -l cur<br>
   cur=`echo $cur | grep -o -- "-t<nowiki>[[:space:]]\+[[:alnum:]]</nowiki>\+" | cut -d' ' -f2`<br>
   reply=(${=$(cat ./tags | grep "^${cur}" | cut -f1)})<br>
 }<br>
 compctl -x 'C[-1,-t]' -K _get_tags -- vim<br>
 #end vim tag
