One-key shell to convert all Chinese text in a repository to English.

I use it to translation Chinese text in my project. I share this to help so many people's time on translate their project.

# A shell, which is utilised to match all Chinese texts.

########################################################################
# Usage:
# Environment requirements:
# 1. install ag(silver searcher).
# 2. install translate-shell.
# ------run---------------
# 1. chmod +x match_chinese.sh
# 2. run './match_chinese.sh' in your project folder.
########################################################################

set -e
# read all text files which contains Chinese and Unicode characters into a variable
FileContainingChineseArr=($(ag -c '[^\x00-\x7F]'))
echo "All files below which contains Chinese or Unicode characters:
"
printf "'%s'\n" "${FileContainingChineseArr[@]}"
#
# to foreach all files
for fileWithLine in ${FileContainingChineseArr[@]}; do
  # to replace chars after colon(:).
  file=($(echo $fileWithLine | sed 's/:.*//g'))

  # to match all Chinese texts
  ChineseTexts=($(cat $file | grep -o -E "[^u4E00-u9FA5]+"))
  echo ""
  echo "$file has Chinese or Unicode characters below:
  "
  echo "
  ----------------------------------------------"
  # to foreach all Chinese texts
  for text in ${ChineseTexts[@]}; do
    # to replace unexpected chars.
    text=($(echo $text | tr -d '\11\12\15\40-\176'))
    if ([[ ! -z "$text" ]]); then
      translatedTxt=$(trans -b :en "$text")
      echo "\"$text\": \"$translatedTxt\","
    fi
  done
done

# cat file.txt | grep -E "[^u4E00-u9FA5]"

In this shell, there is a bug:

结果，如下：is a clauses, but it will be seperated into two words like 结果and如下 .
Despite the bug, this is a convinient shell script for translating my project.

You may need a script to wrap <>中文</> to <>{t('中文')}</>，So I wrote this script:

#!/bin/bash

# set file extensions.
FILE_TYPE=".jsx"

# iterate all files in current directory.
for file in $(find . -type f -name "*$FILE_TYPE"); do
  # to match all Chinese texts
  ChineseTexts=($(cat $file | grep -o -E "\s[^u4E00-u9FA5]+"))
  echo ""
  echo "$file has Chinese or Unicode characters below:
  "
  echo "
  ----------------------------------------------"
  # to foreach all Chinese texts
  for text in ${ChineseTexts[@]}; do
    # to replace unexpected chars.
    text=($(echo $text | tr -d '\11\12\15\40-\176'))
    
    if ([[ ! -z "$text" ]]); then
        if [[ $string == *"'"* ]]; then
            echo "it contains Single quotation marks."
        else
            sed -i -E "s/($text)/{t('\1')}/g" "$file"
            echo "'$text' wrapped up in $file"
        fi
    fi
  done
done

echo "Done!"

This script is not perfect but usable. Pls check code change after running it.
