Applescript替换消息应用程序中发送和接收的消息

我发现这个脚本可以更改消息中字符的大小写，但我想修改这个代码来替换文本中的一些字符串，例如：收到的消息是“我想吃”，这个消息将更改为“我喜欢吃”或“：”更改为“：-”

有一种方法：

set myText to replace_chars("i want to eat", "want", "would like")

on replace_chars(this_text, search_string, replacement_string)
    set AppleScript's text item delimiters to the search_string
    set the item_list to every text item of this_text
    set AppleScript's text item delimiters to the replacement_string
    set this_text to the item_list as string
    set AppleScript's text item delimiters to ""
    return this_text
end replace_chars

set myText to replace_chars("i want to eat", "want", "would like")

on replace_chars(this_text, search_string, replacement_string)
    set AppleScript's text item delimiters to the search_string
    set the item_list to every text item of this_text
    set AppleScript's text item delimiters to the replacement_string
    set this_text to the item_list as string
    set AppleScript's text item delimiters to ""
    return this_text
end replace_chars
