AppleScript读取文件批量输入异常：内容一次性全部输入求助

我有一个包含50行内容的todo-sample.txt文件，内容示例：

Optimize website images
Add pagination to blog post pages
Implement a responsive design for the website
Improve website load speed
Update website copy for SEO 
...

我尝试编写AppleScript解析每行内容，输入到文本框后按下回车，以此快速测试文本输入功能。但运行脚本后，文件所有内容被一次性输入，而非逐行输入后按回车。原脚本如下：

-- Set the path to the input file
set input_file to "/Users/bheng/Sites/notes/Todo/todo-sample.txt"

-- Open the input file
set file_handle to open for access input_file

-- Display a countdown timer
repeat with i from 3 to 1 by -1
    say i
    delay 1
end repeat
say "Go!"

-- Set the delay time between each line
set delay_time to 1

-- Read each line from the file and paste it into the current application
repeat with this_line in (read file_handle using delimiter return)
    tell application "System Events"
        keystroke this_line
        delay delay_time
        key code 36 -- Press enter key
        delay delay_time
    end tell
end repeat

-- Close the input file
close access file_handle

我原本以为只有AppleScript能实现该功能，也接受其他技术或脚本语言的解决方案。

原脚本核心问题是换行符处理错误：

• 现代文本文件默认用LF（\n）作为换行符，但AppleScript里的return对应CR（\r）。
• 用read file_handle using delimiter return读取文件时，找不到匹配的分隔符，整个文件会被当成单个字符串，导致循环仅执行一次，一次性输入所有内容。

以下脚本兼容LF、CR、CR/LF三种换行符，还会过滤空行：

-- 设置输入文件路径
set input_file to "/Users/bheng/Sites/notes/Todo/todo-sample.txt"

-- 读取文件全部内容
set file_content to read input_file

-- 分割内容为行列表（兼容所有常见换行符）
set AppleScript's text item delimiters to {"\n", "\r", "\r\n"}
set line_list to text items of file_content
-- 过滤空行
set filtered_lines to {}
repeat with line_item in line_list
    if line_item is not "" then
        set end of filtered_lines to line_item
    end if
end repeat
set AppleScript's text item delimiters to ""

-- 倒计时提示
repeat with i from 3 to 1 by -1
    say i
    delay 1
end repeat
say "Go!"

-- 设置每行输入的间隔时间
set delay_time to 1

-- 逐行输入并回车
repeat with this_line in filtered_lines
    tell application "System Events"
        keystroke this_line
        delay delay_time
        key code 36 -- 按下回车键
        delay delay_time
    end tell
end repeat

如果需要跨平台的解决方案，可以用Python的pyautogui库，操作更简洁：

1. 先安装依赖：

pip install pyautogui

2. 编写脚本：

import pyautogui
import time

# 文件路径
input_file = "/Users/bheng/Sites/notes/Todo/todo-sample.txt"

# 倒计时
for i in range(3, 0, -1):
    print(i)
    time.sleep(1)
print("Go!")

# 读取文件并过滤空行
with open(input_file, 'r') as f:
    lines = [line.strip() for line in f if line.strip()]

delay_time = 1

# 逐行输入并回车
for line in lines:
    pyautogui.typewrite(line)
    time.sleep(delay_time)
    pyautogui.press('enter')
    time.sleep(delay_time)
