BASE_SRC_FOLDER=../src
IGNORE_FILE_POSTFIX=( "spec.ts" )

GREP_PATTERN="^((?!\/\/).)*\p{Hangul}.*" # for Hangul

CUR_DIR=`pwd`
if [ "`basename $CUR_DIR`" != "script" ]; then
  echo "Error: you must run `basename $0` in script directory."
  exit
fi

echo "Search predefined characters in ts file of ${BASE_SRC_FOLDER} folder."
TS_FILE_LIST=`find ${BASE_SRC_FOLDER} -name "*.ts"`

for CUR_FILE in $TS_FILE_LIST
do
  let IS_RUN=1
  for CUR_IGNORE_FILENAME in ${IGNORE_FILE_POSTFIX[@]}
  do
    if [ "${CUR_FILE%${CUR_IGNORE_FILENAME}}" != ${CUR_FILE} ] ; then
      let IS_RUN=0
      break
    fi
  done
  if [ $IS_RUN -eq 1 ]; then
    grep -nHP "${GREP_PATTERN}"  ${CUR_FILE}
