an apple script used in launchbar 5(maybe other launchers also) which can call Youdao Dict to look for new words, and save the new words in an file so you can review them. still has some problem. like, won't work when Youdao Dict was on the frontmost.

queryThenSaveNewWords.scpt

on WriteToFile(this_data, target_file) -- (string, file path as string)
    do shell script "echo " & quoted form of this_data & ">> " & quoted form of target_file
end WriteToFile

on WordQuery(theString)
    tell application "YoudaoDict" to activate
    
    tell application "System Events"
        tell process "YoudaoDict"
            try
                key down command
                keystroke (key code 51)
            on error
                key up command
            end try
            key up command
            keystroke theString
            keystroke return
        end tell
    end tell
end WordQuery

on handle_string(theString)
    WordQuery(theString)
    WriteToFile(theString, "/tmp/words.log")
end handle_string
