How do I have my Bot respond with arguments?

问题

So I've built a Telegram bot, which can receive the following commands:

/list
/info 123

This works great, as I can catch /info and pass the additional arguments as ints. But, sadly, the Telegram clients don't see /info 123 as a complete command, but just the /info part. Is there a way to make it recognize the entirety of the command as the command?

I've tried Markdown-ing it: [/info 123](/info 123), but no joy. Is this possible?

I've reached out to @BotSupport with the same question, and he/they/it responded swiftly with the following answer:

Hi, at the moment it is not possible to highlight parameters of a command. I any case, you may can find a workaround if you use correct custom keyboards ;) — @BotSupport

Custom keyboards may be an option for someone, but not for me. The solution I've gone for is to give the command as /info123. As the bot receives all / commands, I check if the received command starts with info, and if so, I remove the info part. I convert the remaining string/int to arguments, and pass that along to the relevant command.

you can use RegexHandler() to do this.

Here is an example

def info(bot, update):
  id = update.message.text.replace('/info_', '')
  update.message.reply_text(id, parse_mode='Markdown')


def main():
  updater = Updater(TOKEN)
  updater.dispatcher.add_handler(RegexHandler('^(/info_[\d]+)$', info))
  updater.start_polling()

Usage

The command /info_120 will return 120
and /info_007 will return 007

UPDATE
for newer versions, you may use this method instead!

MessageHandler(Filters.regex(r'pattern'), callback)

If you mean to pass the 123 as an argument for your command info and if you happen to use the python-telegram-bot, then here's how you do it:

dispatcher.add_handler(CommandHandler('hello', SayHello, pass_args=True))

According to the documentation: pass_args Determines whether the handler should be passed the arguments passed to the command as a keyword argument called args. It will contain a list of strings, which is the text following the command split on single or consecutive whitespace characters. Default is False.
