phial package¶

Submodules¶

phial.bot module¶

The core of phial.

class phial.bot.Phial(token, config={'autoReconnect': True, 'baseHelpText': 'All available commands:', 'hotReload': False, 'loopDelay': 0.001, 'maxThreads': 4, 'prefix': '!', 'registerHelpCommand': True})[source]¶

Bases: object

The Phial class acts as the main interface to Slack.

It handles registraion and execution of user defined commands, as well as providing a wrapper around slackclient.SlackClient to make sending messages to Slack simpler.

add_command(pattern, func, case_sensitive=False, help_text_override=None, hide_from_help_command=False)[source]¶

Registers a command with the bot.

This method can be used as a decorator via command()

Parameters

pattern (str) – The pattern that a Message’s text must match for the command to be invoked.
func (Callable[…, Union[None, str, Response, Attachment]]) – The fucntion to be executed when the command is invoked
case_sensitive (bool) –
Whether the pattern should respect case sensitivity.

Defaults to False
help_text_override (Optional[str]) –
Text that should be used as a description of the command using the inbuilt help function.

If not overriden the command’s docstring will be used as the help text.

Defaults to None
hide_from_help_command (Optional[bool]) –
A flag to specify whether or not the inbuilt help command should hide this command from the list it generates.

Defaults to False

Raises

ValueError – If command with the same pattern is already registered

Example

def hello():
    return "world"
bot.add_command('hello', world)

Is the same as

@bot.command('hello')
def hello():
    return "world"

Return type: None

add_fallback_command(func)[source]¶

Add a fallback command.

Registers a ‘fallback’ function to run when a user tries to execute a command that doesn’t exist.

This method can be used as a decorator via fallback_command()

Parameters: func (Callable[[Message], Union[None, str, Response, Attachment]]) – The function to be executed when the user tries to execute a command that doesn’t exist

Example

def error_handler(message: Message) -> str:
    return "Oops that command doesn't seem to exist"

bot.add_fallback_command(error_handler)

Is the same as

@bot.fallback_command()
def error_handler(message: Message) -> str:
    return "Oops that command doesn't seem to exist"

Return type: None

add_middleware(func)[source]¶

Adds a middleware function to the bot.

Middleware functions get passed every message the bot recieves from slack before the bot process the message itself. Returning None from a middleware function will prevent the bot from processing it.

This method can be used as a decorator via middleware().

Parameters: middleware_func – The function to be added to the middleware pipeline

Example

def intercept(messaage):
    return message
bot.add_middleware(intercept)

Is the same as

@bot.middleware()
def intercept(messaage):
    return message

Return type: None

add_scheduled(schedule, func)[source]¶

Adds a scheduled function to the bot.

This method can be used as a decorator via scheduled().

Parameters

schedule (Schedule) – The schedule used to run the function
scheduled_func – The function to be run in accordance to the schedule

Example

def scheduled_beep():
    bot.send_message(Response(text="Beep",
                              channel="channel-id">))
bot.add_scheduled(Schedule().every().day(), scheduled_beep)

Is the same as

@bot.scheduled(Schedule().every().day())
def scheduled_beep():
    bot.send_message(Response(text="Beep",
                              channel="channel-id">))

Return type: None

alias(pattern)[source]¶

A decorator that is used to register an alias for a command.

Parameters: pattern (str) – The pattern that a Message’s text must match for the command to be invoked.

Example

@bot.command('hello')
@bot.alias('goodbye')
def hello():
    return "world"

Return type: Callable

command(pattern, case_sensitive=False, help_text_override=None, hide_from_help_command=False)[source]¶

Registers a command with the bot.

This command is a decorator version of add_command()

Parameters

pattern (str) – The pattern that a Message’s text must match for the command to be invoked.
case_sensitive (bool) –
Whether the pattern should respect case sensitivity.

Defaults to False
help_text_override (Optional[str]) –
Text that should be used as a description of the command using the inbuilt help function.

If not overriden the command’s docstring will be used as the help text.

Defaults to None
hide_from_help_command (Optional[bool]) –
A flag to specify whether or not the inbuilt help command should hide this command from the list it generates.

Defaults to False

Example

@bot.command('hello')
def hello():
    return "world"

@bot.command('caseSensitive', case_sensitive=True)
def case_sensitive():
    return "You typed caseSensitive"

Return type: Callable
