Problem here:

    % vi *(.om[$1])         
    zsh: bad math expression: operand expected at `'
    % 

Please advise. My environment is:

    % echo $ZSH_VERSION     
    4.3.17                  # this host is debian 7.2 (debian stable)
    % setopt | sort | column
    allexport               interactive             nobgnice
    autocd                  interactivecomments     nohup
    correctall              longlistjobs            nonomatch
    extendedglob            markdirs                pathdirs
    globdots                menucomplete            pushdsilent
    histignoredups          noautolist              shinstdin
    ignoreeof               nobeep
    %

I think you want

  vi *(.om[1])

or if you wanted to be really different

  vi *(.Om[-1])

Otherwise you're substituting a positional parameter, which you don't
want.  The error you got comes from it being empty, so there's no
number, which is what it's complaining about, slightly cryptically.

Twitter Daily ZSH Tip

Hi

Noticing that a previous ZSH Daily Tip Twitter feed had ceased in 2010 I 
have started a new one

https://twitter.com/dailyzshtip

I hope it will help popularize our favorite shell.

It will feature day-to-day practical stuff such as

vi *(.om[$1])   # vim newest file

Any tips, advice or retweeting welcome!

The [$1] should probably be [1] ;)

Valodim,
Whoops yes I carelessly borrowed that from my .zshrc where I have a 
function which allows me specify more options

function vew()
{
# name : vew
# description : vi newest file
# or nth newest file if a numeric parameter
# or newest file with $1 string in name
if [ $# -gt 0 ]
then
   if [[ "$1" == [0-9] ]]
   then
   gvim.exe *(.om[$1]) &
   else
   gvim.exe *$1*(.om[1]) &
fi
else
gvim.exe *~vssver.scc(.om[1]) &
fi
}
