[Linux/Grep] How to find hangul or japanese characters in soruce code

Following scripts offer you that finding Hangul, Katakana, Hiragana, Ganji(Han), Hiragana in your source code (ts file)

"^((?!\/\/).)*"means that ignore "// comments".
The script uses "property-name" of Regular Expressions.

#!/bin/bash

BASE_SRC_FOLDER=../src
IGNORE_FILE_POSTFIX=( "spec.ts" )
#GREP_PATTERN="^((?!\/\/).)*(\p{Hiragana}|\p{Han}|\p{Katakana})" # for Japanse
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}
  fi
done

sanitize on in CMakeLists.txt

1. CMakeLists.txt set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -fsanitize=address") add_compile_options(-fsanitize=address) If a subdir is set with add_subdirectory and a module that does not support sanitize is imported from the path and needs to be removed, add -fno-sanitize=address to add_compile_options in CMakeLists.txt of the subdir to remove it. Basically, if you enable sanitize, sanitize will adjust ulimit's core to 0, so core will not occur. You can do this by putting the following part as an environment variable. (Below is the part you put in systemd's service) 2. service file in systemd [Service] LimitCORE=infinity Environment="ASAN_OPTIONS=handle_segv=0:handle_abort=1:abort_on_error=1:disable_coredump=0"
