|
|
This Bot uses the Updater class to handle the bot.
|
|
|
|
First, a few handler functions are defined. Then, those functions are passed to
|
|
the Dispatcher and registered at their respective places.
|
|
Then, the bot is started and runs until we press Ctrl-C on the command line.
|
|
|
|
Usage:
|
|
Basic inline bot example. Applies different text transformations.
|
|
Press Ctrl-C on the command line or send a signal to the process to stop the
|
|
bot.
