我正在 Python 中开发一个 Discord 机器人，它根据用户输入输出文本.我想避免用户让它说 @everyone(和 @here)，这会标记和惹恼所有人.
I'm developing a Discord bot in Python which outputs text based on user input. I want to avoid users getting it to say @everyone (and @here) which would tag and annoy everyone.
我尝试使用 @everyone 与 @everyone 相比，它不会使文本本身变成蓝色，但它仍然会触发 ping 并突出显示该行黄色.这不仅会在我使用机器人发送消息时发生，而且在我直接使用 Discord 时也会发生.
I tried using @everyone which in contrast to @everyone does not make the text itself blue, but it still triggers a ping and highlights the line in yellow. This does not only happen when I send a message with the bot but also if I use Discord directly.
我一直使用的解决方案是插入一个 零宽度空格在@"之后.这不会改变文本外观(零宽度")，但额外的字符会阻止 ping.它具有 unicode 代码点 200b(十六进制):
The solution I've been using is to insert a zero-width space after the '@'. This will not change the text appearance ('zero-width') but the extra character prevents the ping. It has unicode codepoint 200b (in hex):
message_str = message_str.replace('@', '@u200b')
更明确地说，discord.py 库本身有 escape_mentions 用于此目的:
More explicitly, the discord.py library itself has escape_mentions for that purpose:
message_str = discord.utils.escape_mentions(message_str)
实现几乎相同:
def escape_mentions(text):
return re.sub(r'@(everyone|here|[!&]?[0-9]{17,21})', '@u200b\1', text)
