Re: zsh tips plea (tip of the day)

Hi

Here's a script written to test zsh itself seems to contain some good examples  of globbing

#!/usr/local/bin/zsh -f

setopt extendedglob badpattern
unsetopt kshglob

failed=0
while read res str pat; do
  [[ $res = '#' ]] && continue
  [[ $str = ${~pat} ]]
  ts=$?
  [[ $1 = -q ]] || print "$ts:  [[ $str = $pat ]]"
  if [[ ( $ts -gt 0 && $res = t) || ($ts -eq 0 && $res = f) ]]; then
    print "Test failed:  [[ $str = $pat ]]"
    (( failed++ ))
  fi
done <<EOT
