#

# grep the y2log files for the pkg-bindings calls, read the calls into an array,
# use zgrep so it can read also the compressed files (y2log-*.gz)
mapfile -t CALLS < <( zgrep "Pkg Builtin called" "$@" | sed -e "s/^.* Pkg Builtin called: //" | sort -u )

for C in "${CALLS[@]}"; do
  # use the first found occurence
  URL=$(grep -r -n  "PkgFunctions::$C\\b" . | sed -e "s/\\.cc:\\([0-9]\\+\\):.*/.cc#L\\1/" -e "s@^./@https://github.com/yast/yast-pkg-bindings/blob/master/@" | head -n 1)
