The bot and its state#

class sopel.bot.Sopel(config, daemon=False)#

Bases: AbstractBot

action(text: str, dest: str) None#

Send a CTCP ACTION PRIVMSG to a user or channel.

Parameters:
  • text (str) – the text to send in the CTCP ACTION

  • dest (str) – the destination of the CTCP ACTION

The same loop detection and length restrictions apply as with say(), though automatic message splitting is not available.

add_plugin(plugin, callables, jobs, shutdowns, urls) None#

Add a loaded plugin to the bot’s registry.

Parameters:
  • plugin (sopel.plugins.handlers.AbstractPluginHandler) – loaded plugin to add

  • callables (iterable) – an iterable of callables from the plugin

  • jobs (iterable) – an iterable of functions from the plugin that are periodically invoked

  • shutdowns (iterable) – an iterable of functions from the plugin that should be called on shutdown

  • urls (iterable) – an iterable of functions from the plugin to call when matched against a URL

backend: AbstractIRCBackend#

IRC Connection Backend.

call(
func: Any,
sopel: SopelWrapper,
trigger: Trigger,
) None#

Call a function, applying any rate limits or other restrictions.

Parameters:
  • func (function) – the function to call

  • sopel (SopelWrapper) – a SopelWrapper instance

  • trigger (Trigger) – the Trigger object for the line from the server that triggered this call

property cap_requests: Manager#

Capability Requests manager.

property capabilities: Capabilities#

Capabilities negotiated with the server.

change_current_nick(new_nick: str) None#

Change the current nick without configuration modification.

Parameters:

new_nick (str) – new nick to be used by the bot

channels#

A map of the channels that Sopel is in.

The keys are Identifiers of the channel names, and map to Channel objects which contain the users in the channel and their permissions.

property command_groups: dict[str, list]#

A mapping of plugin names to lists of their commands.

Changed in version 7.1: This attribute is now generated on the fly from the registered list of commands and nickname commands.

property config: Config#

The sopel.config.Config for the current Sopel instance.

property connection_registered: bool#

Whether the IRC connection is registered.

This is a property so it can accurately reflect not only the socket state (connection to IRC server), but also whether the connection is ready to accept “normal” IRC commands.

Before registration is completed, only a very limited set of commands are allowed to be used. Sopel itself takes care of these, so plugins will be more concerned with whether they are allowed to use methods like say() yet.

db#

The bot’s database, as a sopel.db.SopelDB instance.

dispatch(pretrigger: PreTrigger) None#

Dispatch a parsed message to any registered callables.

Parameters:

pretrigger (PreTrigger) – a parsed message from the server

The pretrigger (a parsed message) is used to find matching rules; it will retrieve them by order of priority, and execute them. It runs triggered rules in separate threads, unless they are marked otherwise.

However, it won’t run triggered blockable rules at all when they can’t be executed for blocked nickname or hostname.

See also

The pattern matching is done by the Rules Manager.

property doc: dict[str, tuple]#

A dictionary of command names to their documentation.

Each command is mapped to its docstring and any available examples, if declared in the plugin’s code.

Changed in version 3.2: Use the first item in each callable’s commands list as the key, instead of the function name as declared in the source code.

Changed in version 7.1: This attribute is now generated on the fly from the registered list of commands and nickname commands.

property enabled_capabilities: set[str]#

A set containing the IRCv3 capabilities that the bot has enabled.

Deprecated since version 8.0: Enabled server capabilities are now managed by bot.capabilities and its various methods and attributes:

Will be removed in Sopel 9.

error(
trigger: Trigger | None = None,
exception: BaseException | None = None,
)#

Called internally when a plugin causes an error.

Parameters:
get_irc_backend(
host: str,
port: int,
source_address: tuple[str, int] | None,
) AbstractIRCBackend#

Set up the IRC backend based on the bot’s settings.

Returns:

the initialized IRC backend object

Return type:

an object implementing the interface of AbstractIRCBackend

get_plugin_meta(name: str) dict#

Get info about a registered plugin by its name.

Parameters:

name (str) – name of the plugin about which to get info

Returns:

the plugin’s metadata (see get_meta_description())

Return type:

dict

Raises:

plugins.exceptions.PluginNotRegistered – when there is no name plugin registered

has_channel_privilege(channel, privilege) bool#

Tell if the bot has a privilege level or above in a channel.

Parameters:
  • channel (str) – a channel the bot is in

  • privilege (int) – privilege level to check

Raises:

ValueError – when the channel is unknown

This method checks the bot’s privilege level in a channel, i.e. if it has this level or higher privileges:

>>> bot.channels['#chan'].privileges[bot.nick] = plugin.OP
>>> bot.has_channel_privilege('#chan', plugin.VOICE)
True

The channel argument can be either a str or an Identifier, as long as Sopel joined said channel. If the channel is unknown, a ValueError will be raised.

has_plugin(name: str) bool#

Check if the bot has registered a plugin of the specified name.

Parameters:

name (str) – name of the plugin to check for

Returns:

whether the bot has a plugin named name registered

Return type:

bool

property hostmask: str | None#

The current hostmask for the bot User.

Returns:

the bot’s current hostmask if the bot is connected and in a least one channel; None otherwise

Return type:

Optional[str]

property isupport: ISupport#

Features advertised by the server.

Type:

ISupport instance

join(channel: str, password: str | None = None) None#

Join a channel.

Parameters:
  • channel (str) – the channel to join

  • password (str) – an optional channel password

If channel contains a space, and no password is given, the space is assumed to split the argument into the channel to join and its password. channel should not contain a space if password is given.

kick(nick: str, channel: str, text: str | None = None) None#

Kick a nick from a channel.

Parameters:
  • nick – nick to kick out of the channel

  • channel – channel to kick nick from

  • text – optional text for the kick

The bot must be an operator in the specified channel for this to work.

New in version 7.0.

log_raw(line: str, prefix: str) None#

Log raw line to the raw log.

Parameters:
  • line (str) – the raw line

  • prefix (str) – additional information to prepend to the log line

The prefix is usually either >> for an outgoing line or << for a received one.

make_identifier(name: str) Identifier#

Instantiate an Identifier using the bot’s context.

New in version 8.0.

make_identifier_memory() SopelIdentifierMemory#

Instantiate a SopelIdentifierMemory using the bot’s context.

This is a shortcut for SopelIdentifierMemory’s most common use case, which requires remembering to pass the bot’s own make_identifier() method so the SopelIdentifierMemory will cast its keys to Identifiers that are compatible with what the bot tracks internally and sends with Triggers when a plugin callable runs.

Calling this method is equivalent to the following:

from sopel.tools import memories

memories.SopelIdentifierMemory(
    identifier_factory=bot.make_identifier,
)

New in version 8.0.

See also

The tools.memories module describes how to use SopelIdentifierMemory and its siblings.

memory#

A thread-safe dict for storage of runtime data to be shared between plugins. See sopel.tools.memories.SopelMemory.

modeparser#

A mode parser used to parse MODE messages and modestrings.

property myinfo: MyInfo#

Server/network information.

Type:

MyInfo instance

New in version 7.0.

property name: str#

Sopel’s “real name”, as used for WHOIS responses.

property nick: Identifier#

Sopel’s current nick.

Changing this while Sopel is running is unsupported and can result in undefined behavior.

notice(text: str, dest: str) None#

Send an IRC NOTICE to a user or channel (dest).

Parameters:
  • text – the text to send in the NOTICE

  • dest – the destination of the NOTICE

on_close() None#

Call shutdown methods.

on_connect() None#

Handle successful establishment of IRC connection.

Handle any uncaptured error in the bot itself.

on_job_error(
scheduler: Scheduler,
job: Job,
exc: BaseException,
)#

Called when a job from the Job Scheduler fails.

See also

Sopel.error()

on_message(message: str) None#

Handle an incoming IRC message.

Parameters:

message (str) – the received raw IRC message

on_message_sent(raw: str) None#

Handle any message sent through the connection.

Parameters:

raw (str) – raw text message sent through the connection

When a message is sent through the IRC connection, the bot will log the raw message. If necessary, it will also simulate the echo-message feature of IRCv3.

on_scheduler_error(
scheduler: Scheduler,
exc: BaseException,
)#

Called when the Job Scheduler fails.

Parameters:

See also

Sopel.error()

part(channel: str, msg: str | None = None) None#

Leave a channel.

Parameters:
  • channel – the channel to leave

  • msg – the message to display when leaving a channel

property plugins: Mapping[str, plugins.handlers.AbstractPluginHandler]#

A dict of the bot’s currently loaded plugins.

Returns:

an immutable map of plugin name to plugin object

post_setup() None#

Perform post-setup actions.

This method handles everything that should happen after all the plugins are loaded, and before the bot can connect to the IRC server.

At the moment, this method checks for undefined configuration options, and starts the job scheduler.

New in version 7.1.

quit(message: str | None = None) None#

Disconnect from IRC and close the bot.

Parameters:

message – optional QUIT message to send (e.g. “Bye!”)

rebuild_nick() None#

Rebuild nick as a new identifier.

This method exists to update the casemapping rules for the Identifier that represents the bot’s nick, e.g. after ISUPPORT info is received.

register_url_callback(pattern, callback)#

Register a callback for URLs matching the regex pattern.

Parameters:
  • pattern (re.Pattern) – compiled regex pattern to register

  • callback (function) – callable object to handle matching URLs

New in version 7.0: This method replaces manual management of url_callbacks in Sopel’s plugins, so instead of doing this in setup():

if 'url_callbacks' not in bot.memory:
    bot.memory['url_callbacks'] = tools.SopelMemory()

regex = re.compile(r'http://example.com/path/.*')
bot.memory['url_callbacks'][regex] = callback

use this much more concise pattern:

regex = re.compile(r'http://example.com/path/.*')
bot.register_url_callback(regex, callback)

It’s recommended you completely avoid manual management of URL callbacks through the use of sopel.plugin.url().

Deprecated since version 7.1: Made obsolete by fixes to the behavior of sopel.plugin.url(). Will be removed in Sopel 9.

Changed in version 8.0: Stores registered callbacks in an internal property instead of bot.memory['url_callbacks'].

reload_plugin(name) None#

Reload a plugin.

Parameters:

name (str) – name of the plugin to reload

Raises:

plugins.exceptions.PluginNotRegistered – when there is no name plugin registered

This function runs the plugin’s shutdown routine and unregisters the plugin from the bot. Then this function reloads the plugin, runs its setup routines, and registers it again.

reload_plugins() None#

Reload all registered plugins.

First, this function runs all plugin shutdown routines and unregisters all plugins. Then it reloads all plugins, runs their setup routines, and registers them again.

remove_plugin(plugin, callables, jobs, shutdowns, urls) None#

Remove a loaded plugin from the bot’s registry.

Parameters:
  • plugin (sopel.plugins.handlers.AbstractPluginHandler) – loaded plugin to remove

  • callables (iterable) – an iterable of callables from the plugin

  • jobs (iterable) – an iterable of functions from the plugin that are periodically invoked

  • shutdowns (iterable) – an iterable of functions from the plugin that should be called on shutdown

  • urls (iterable) – an iterable of functions from the plugin to call when matched against a URL

reply(text: str, dest: str, reply_to: str, notice: bool = False) None#

Send a PRIVMSG to a user or channel, prepended with reply_to.

Parameters:
  • text – the text of the reply

  • dest – the destination of the reply

  • reply_to – the nickname that the reply will be prepended with

  • notice – whether to send the reply as a NOTICE or not, defaults to False

If notice is True, send a NOTICE rather than a PRIVMSG.

The same loop detection and length restrictions apply as with say(), though automatic message splitting is not available.

request_capabilities() bool#

Request available capabilities and return if negotiation is on.

Returns:

tell if the negotiation is active or not

This takes the available capabilities and asks the request manager to request only these that are available.

If none is available or if none is requested, the negotiation is not active and this returns False. It is the responsibility of the caller to make sure it signals the IRC server to end the negotiation with a CAP END command.

restart(message: str | None = None) None#

Disconnect from IRC and restart the bot.

Parameters:

message – optional QUIT message to send (e.g. “Be right back!”)

resume_capability_negotiation(
cap_req: tuple[str, ...],
plugin_name: str,
) None#

Resume capability negotiation and close when necessary.

Parameters:
  • cap_req – a capability request

  • plugin_name – plugin that requested the capability and wants to resume capability negotiation

This will resume a capability request through the bot’s capability requests manager, and if the negotiation wasn’t completed before and is now complete, it will send a CAP END command.

This method must be used by plugins that declare a capability request with a handler that returns sopel.plugin.CapabilityNegotiation.CONTINUE on acknowledgement in order for the bot to resume and eventually close negotiation.

For example, this is useful for SASL auth which happens while negotiating capabilities.

property rules: Manager#

Rules manager.

run(host: str, port: int = 6667) None#

Connect to IRC server and run the bot forever.

Parameters:
  • host (str) – the IRC server hostname

  • port (int) – the IRC server port

property running_triggers: list#

Current active threads for triggers.

Returns:

the running thread(s) currently processing trigger(s)

Return type:

iterable

This is for testing and debugging purposes only.

safe_text_length(recipient: str) int#

Estimate a safe text length for an IRC message.

Returns:

the maximum possible length of a message to recipient

When the bot sends a message to a recipient (channel or nick), it has 512 bytes minus the command, arguments, various separators and trailing CRLF for its text. However, this is not what other users will see from the server; the message forwarded to other clients will be sent using this format:

:nick!~user@hostname PRIVMSG #channel :text

Which takes more bytes, reducing the maximum length available for a single line of text. This method computes a safe length of text that can be sent using PRIVMSG or NOTICE by subtracting the size required by the server to convey the bot’s message.

See also

This method is useful when sending a message using say(), and can be used with sopel.tools.get_sendable_message().

say(
text: str,
recipient: str,
max_messages: int = 1,
truncation: str = '',
trailing: str = '',
) None#

Send a PRIVMSG to a user or channel.

Parameters:
  • text – the text to send

  • recipient – the message recipient

  • max_messages – split text into at most this many messages if it is too long to fit in one (optional)

  • truncation – string to append if text is too long to fit in a single message, or into the last message if max_messages is greater than 1 (optional)

  • trailing – string to append after text and (if used) truncation (optional)

By default, this will attempt to send the entire text in one message. If the text is too long for the server, it may be truncated.

If max_messages is given, the text will be split into at most that many messages. The split is made at the last space character before the “safe length” (which is calculated based on the bot’s nickname and hostmask), or exactly at the “safe length” if no such space character exists.

If the text is too long to fit into the specified number of messages using the above splitting, the final message will contain the entire remainder, which may be truncated by the server. You can specify truncation to tell Sopel how it should indicate that the remaining text was cut off. Note that the truncation parameter must include leading whitespace if you desire any between it and the truncated text.

The trailing parameter is always appended to text, after the point where truncation would be inserted if necessary. It’s useful for making sure e.g. a link is always included, even if the summary your plugin fetches is too long to fit.

Here are some examples of how the truncation and trailing parameters work, using an artificially low maximum line length:

# bot.say() outputs <text> + <truncation?> + <trailing>
#                   always     if needed       always

bot.say(
    '"This is a short quote.',
    truncation=' […]',
    trailing='"')
# Sopel says: "This is a short quote."

bot.say(
    '"This quote is very long and will not fit on a line.',
    truncation=' […]',
    trailing='"')
# Sopel says: "This quote is very long […]"

bot.say(
    # note the " included at the end this time
    '"This quote is very long and will not fit on a line."',
    truncation=' […]')
# Sopel says: "This quote is very long […]
# The ending " goes missing

New in version 7.1: The truncation and trailing parameters.

property scheduler: Scheduler#

Job Scheduler. See sopel.plugin.interval().

search_url_callbacks(url)#

Yield callbacks whose regex pattern matches the url.

Parameters:

url (str) – URL found in a trigger

Returns:

yield 2-value tuples of (callback, match)

For each pattern that matches the url parameter, it yields a 2-value tuple of (callable, match) for that pattern.

The callable is the one registered with register_url_callback(), and the match is the result of the regex pattern’s search method.

New in version 7.0.

Changed in version 8.0: Searches for registered callbacks in an internal property instead of bot.memory['url_callbacks'].

Deprecated since version 8.0: Made obsolete by fixes to the behavior of sopel.plugin.url(). Will be removed in Sopel 9.

See also

The Python documentation for the re.search function and the match object.

property server_capabilities: dict[str, str | None]#

A dict mapping supported IRCv3 capabilities to their options.

For example, if the server specifies the capability sasl=EXTERNAL, it will be here as {"sasl": "EXTERNAL"}. Capabilities specified without any options will have None as the value.

For servers that do not support IRCv3, this will be an empty set.

Deprecated since version 8.0: Enabled server capabilities are now managed by bot.capabilities and its various methods and attributes:

Will be removed in Sopel 9.

settings#

Bot settings.

setup() None#

Set up Sopel bot before it can run.

The setup phase is in charge of:

  • setting up logging (configure Python’s built-in logging)

  • setting up the bot’s plugins (load, setup, and register)

  • starting the job scheduler

setup_logging() None#

Set up logging based on config options.

setup_plugins() None#

Load plugins into the bot.

shutdown_methods#

List of methods to call on shutdown.

unregister_url_callback(pattern, callback)#

Unregister the callback for URLs matching the regex pattern.

Parameters:
  • pattern (re.Pattern) – compiled regex pattern to unregister callback

  • callback (function) – callable object to remove

New in version 7.0: This method replaces manual management of url_callbacks in Sopel’s plugins, so instead of doing this in shutdown():

regex = re.compile(r'http://example.com/path/.*')
try:
    del bot.memory['url_callbacks'][regex]
except KeyError:
    pass

use this much more concise pattern:

regex = re.compile(r'http://example.com/path/.*')
bot.unregister_url_callback(regex, callback)

It’s recommended you completely avoid manual management of URL callbacks through the use of sopel.plugin.url().

Deprecated since version 7.1: Made obsolete by fixes to the behavior of sopel.plugin.url(). Will be removed in Sopel 9.

Changed in version 8.0: Deletes registered callbacks from an internal property instead of bot.memory['url_callbacks'].

property user: str#

Sopel’s user/ident.

users#

A map of the users that Sopel is aware of.

The keys are Identifiers of the nicknames, and map to User instances. In order for Sopel to be aware of a user, it must share at least one mutual channel.

write(args: Iterable[str], text: str | None = None) None#

Send a command to the server.

Parameters:
  • args – an iterable of strings, which will be joined by spaces

  • text – a string that will be prepended with a : and added to the end of the command

args is an iterable of strings, which are joined by spaces. text is treated as though it were the final item in args, but is preceded by a :. This is a special case which means that text, unlike the items in args, may contain spaces (though this constraint is not checked by write).

In other words, both sopel.write(('PRIVMSG',), 'Hello, world!') and sopel.write(('PRIVMSG', ':Hello, world!')) will send PRIVMSG :Hello, world! to the server.

Newlines and carriage returns ('\n' and '\r') are removed before sending. Additionally, if the message (after joining) is longer than than 510 characters, any remaining characters will not be sent.

See also

The connection backend is responsible for formatting and sending the message through the IRC connection. See the sopel.irc.abstract_backends.AbstractIRCBackend.send_command() method for more information.

class sopel.bot.SopelWrapper(sopel, trigger, output_prefix='')#

Bases: object

Wrapper around a Sopel instance and a Trigger.

Parameters:
  • sopel (Sopel) – Sopel instance

  • trigger (Trigger) – IRC Trigger line

  • output_prefix (str) – prefix for messages sent through this wrapper (e.g. plugin tag)

This wrapper will be used to call Sopel’s triggered commands and rules as their bot argument. It acts as a proxy, providing the trigger’s sender (source channel or private message) as the default destination argument for overridden methods.

Deprecated since version 8.0: SopelWrapper will be replaced with a contextvars based alternative. For more information, see #2460.

action(message, destination=None)#

Override Sopel.action to use trigger source by default.

Parameters:
  • message (str) – action message

  • destination (str) – channel or nickname; defaults to trigger.sender

The destination will default to the channel in which the trigger happened (or nickname, if received in a private message).

property default_destination: str | None#

Default say/reply destination for the associated Trigger.

Returns:

the channel (with status prefix) or nick to send messages to

This property returns the str version of the destination that will be used by default by these methods:

For a channel, it also ensures that the status-specific prefix is added to the result, so the bot replies with the same status.

kick(nick, channel=None, message=None)#

Override Sopel.kick to kick in a channel

Parameters:
  • nick (str) – nick to kick out of the channel

  • channel (str) – optional channel to kick nick from

  • message (str) – optional message for the kick

The channel will default to the channel in which the call was triggered. If triggered from a private message, channel is required.

notice(message, destination=None)#

Override Sopel.notice to use trigger source by default.

Parameters:
  • message (str) – notice message

  • destination (str) – channel or nickname; defaults to trigger.sender

The destination will default to the channel in which the trigger happened (or nickname, if received in a private message).

reply(message, destination=None, reply_to=None, notice=False)#

Override Sopel.reply to reply_to sender by default.

Parameters:
  • message (str) – reply message

  • destination (str) – channel or nickname; defaults to trigger.sender

  • reply_to (str) – person to reply to; defaults to trigger.nick

  • notice (bool) – reply as an IRC notice or with a simple message

The destination will default to the channel in which the trigger happened (or nickname, if received in a private message).

reply_to will default to the nickname who sent the trigger.

say(
message,
destination=None,
max_messages=1,
truncation='',
trailing='',
)#

Override Sopel.say to use trigger source by default.

Parameters:
  • message (str) – message to say

  • destination (str) – channel or nickname; defaults to trigger.sender

  • max_messages (int) – split message into at most this many messages if it is too long to fit into one line (optional)

  • truncation (str) – string to indicate that the message was truncated (optional)

  • trailing (str) – string that should always appear at the end of message (optional)

The destination will default to the channel in which the trigger happened (or nickname, if received in a private message).
