Brew - better Brewfile creation (without the file)

brew_export.sh

brew_export() {
  # brew bundle is a pain... it dumps to a forced Brewfile, and is not
  # consistently sorted, making version controling your Brewfile in a dotfile
  # repo tricky. #FixedIt

  # makes a Brewfile
  brew bundle dump --force

  # add custom sort column
  awkcmd='
    BEGIN{FS=OFS=" "}
    /^tap/  {print 1 "\t" $0; next}
    /^brew/ {print 2 "\t" $0; next}
    /^cask/ {print 3 "\t" $0; next}
    /^mas/  {print 4 "\t" $0; next}
            {print 9 "\t" $0}
  '

  # output the sorted brewfile, adding then removing the sort column
  cat Brewfile | awk "$awkcmd" | sort | awk 'BEGIN{FS="\t";OFS=""}{$1=""; print $0}'

  # we never needed this anyway
  command rm Brewfile
}
