* Remove error handlers from examples
Most examples use the same error handler, that error handler logs
update.to_dict but doesn't log error traceback. Hiding error traceback
is quite bad, removing the error handler entirely causes PTB to use
default error logging which does include error traceback.
* adding error handling example
* Change error handler example
Including:
- Change the telegram message to include usual python error message.
- HTML-escape the strings used to build the telegram message.
- Capitalize comments and add more empty lines to hopefully unify the
style with other examples, at least a bit.
- Reorder imports.
* Add an error-rising command to the error handler example
* Slightly change example error handler docstring and comments
* Make telegram message sent by the error handler example more readable
* Rename error_handler.py to errorhandlerbot.py and add a start command
* Change error handler example to work without developer chat id
* Revert "Change error handler example to work without developer chat id"
This reverts commit c4efea6f
* Make bot token a module level constant in the error handler example
Otherwise the example will require two edits 40 lines apart to run.
* Show chat id in start command of the error handler example
The example requires you to set developer chat id, this change will
make things easier for users that don't know how to see their chat id.
* Add errorhandlerbot.py to the examples folder readme

"""
|
|
Simple Bot to reply to Telegram messages.
|
|
|
|
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 Echobot example, repeats messages.
|
|
Press Ctrl-C on the command line or send a signal to the process to stop the
|
|
bot.
