        ## Parameters
        
        ~~~py
        irc = miniirc.IRC(ip, port, nick, channels=None, *, ssl=None, ident=None, realname=None, persist=True, debug=False, ns_identity=None, auto_connect=True, ircv3_caps=set(), quit_message='I grew sick and died.', ping_interval=60, ping_timeout=None, verify_ssl=True)
        ~~~
        
        *Note that everything before the \* is a positional argument.*
        
        | Parameter     | Description                                                |
        | ------------- | -------------------------------------------------------- |
        | `ip`          | The IP/hostname of the IRC server to connect to.          |
        | `port`        | The port to connect to.                                   |
        | `nick`        | The nickname of the bot.                                  |
        | `channels`    | The channels to join on connect. This can be an iterable containing strings (list, set, etc), or (since v1.5.0) a comma-delimited string. |
        | `ssl`         | Enable TLS/SSL. If `None`, TLS/SSL is disabled unless the port is `6697`. |
        | `ident`       | The ident to use, defaults to `nick`.                     |
        | `realname`    | The realname to use, defaults to `nick` as well.          |
        | `persist`     | Whether to automatically reconnect.                       |
        | `debug`       | Enables debug mode, prints all IRC messages. This can also be a file-like object (with write mode enabled) if you want debug messages to be written into a file instead of being printed to stdout, or a function (for example `logging.debug`). |
        | `ns_identity` | The NickServ account to use as a tuple/list of length 2 (`('<user>', '<password>')`). For compatibility, this can be a string (`'<user> <password>'`). |
        | `auto_connect`| Runs `.connect()` straight away.                          |
        | `ircv3_caps`  | A set() of additional IRCv3 capabilities to request. SASL is auto-added if `ns_identity` is specified. |
        | `connect_modes` | A mode string (for example `'+B'`) of UMODEs to set when connected. |
        | `quit_message`| Sets the default quit message. This can be modified per-quit with `irc.disconnect()`. |
        | `ping_interval` | If no packets are sent or received for this amount of seconds, miniirc will send a `PING`, and if no reply is sent, after the ping timeout, miniirc will attempt to reconnect. Set to `None` to disable. |
        | `ping_timeout` | The ping timeout used alongside the above `ping_interval` option, if unspecified will default to `ping_interval`. |
        | `verify_ssl`  | Verifies TLS/SSL certificates. Disabling this is not recommended as it opens the IRC connection up to MiTM attacks. If you have trouble with certificate verification, try running `pip3 install certifi` first. |
        
        *The only mandatory parameters are `ip`, `port`, and `nick`.*
        
        ## Functions
        
        | Function      | Description                                               |
        | ------------- | --------------------------------------------------------  |
        | `change_parser(parser=...)` | *See the message parser section for documentation.* |
        | `connect()`   | Connects to the IRC server if not already connected.      |
        | `ctcp(target, *msg, reply=False, tags=None)` | Sends a `CTCP` request or reply to `target`. |
        | `debug(...)`  | Debug, calls `print(...)` if debug mode is on.            |
        | `disconnect(msg=..., *, auto_reconnect=False)`| Disconnects from the IRC server. `auto_reconnect` will be overriden by `self.persist` if set to `True`. |
        | `Handler(...)` | An event handler, see [Handlers](#handlers) for more info. |
        | `me(target, *msg, tags=None)`        | Sends a `/me` (`CTCP ACTION`) to `target`.  |
        | `msg(target, *msg, tags=None)`       | Sends a `PRIVMSG` to `target`. `target` should not contain spaces or start with a colon. |
        | `notice(target, *msg, tags=None)`    | Sends a `NOTICE` to `target`. `target` should not contain spaces or start with a colon. |
        | `quote(*msg, force=False, tags=None)` | Sends a raw message to IRC, use `force=True` to send while disconnected. Do not send multiple commands in one `irc.quote()`, as the newlines will be stripped and it will be sent as one command. The `tags` parameter optionally allows you to add a `dict` with IRCv3 client tags (all starting in `+`), and will not be sent to IRC servers that do not support client tags. |
        | `send(*msg, force=False, tags=None)` | Sends a command to the IRC server, treating every positional argument as a parameter. The usage of this is recommended over `irc.quote()` unless you know what you are doing. |
        
        *Note that if `force=False` on `irc.quote` (or `irc.msg` etc is called) while
        miniirc is not connected, messages will be temporarily stored and then sent
        once miniirc is connected. Setting `force=True` will throw errors if miniirc is
        completely disconnected (`irc.connected` is `None`).*
        
        ### irc.quote and irc.send
        
        The two functions `irc.quote` and `irc.send` may sound similar, however are
        fundamentally different: `irc.quote()` joins all provided arguments with spaces
        and sends them as a raw message to IRC, while `irc.send()` treats each argument
        as a parameter. If arguments passed to `irc.send()` contain spaces, they are
        replaced with U+00A0 (a non-breaking space, visually similar to a regular
        space however not interpreted as one).
        
        #### Examples
        
         - `irc.quote('PRIVMSG', '#channel :Hello,', 'world!')` sends "Hello, world!"
            to #channel.
         - `irc.quote('PRIVMSG', '#channel', 'Hello, world!')` is invalid ("Hello," and
            "world!" are sent as separate parameters).
         - `irc.send('PRIVMSG', '#channel', 'Hello, world!')` will send "Hello, world!"
            to "#channel".
         - `irc.send('PRIVMSG', '#channel :Hello,', 'world!')` will send "world!" to
            `#channel\xa0:Hello,`, where `\xa0` is a non-breaking space.
        
        *If you are unsure and do not need compatibility with miniirc <1.5.0, use
        `irc.send()`. `PRIVMSG` is just used as an example, if you need to send
        `PRIVMSG`s use `irc.msg()` instead.*
        
        ## Variables
        
        *These variables should not be changed outside `miniirc.py`.*
        
        | Variable      | Description                                               |
        | ------------- | --------------------------------------------------------  |
        | `active_caps` | A `set` of IRCv3 capabilities that have been successfully negotiated with the IRC server. This is empty while disconnected. |
        | `connected`   | A boolean (or `None`), `True` when miniirc is connected, `False` when miniirc is connecting, and `None` when miniirc is not connected. |
        | `current_nick` | *New in v1.4.3.* The bot/client's current nickname, currently an alias for `irc.nick`. Do not modify this, and use this instead of `irc.nick` when getting the bot's current nickname for compatibility with miniirc v2.0.0. |
        | `isupport`    | A `dict` with values (not necessarily strings) from `ISUPPORT` messages sent to the client. |
        | `msglen`      | The maximum length (in bytes) of messages (including `\r\n`). This is automatically changed if the server supports the `oragono.io/maxline-2` capability. |
        | `nick`        | The nickname to use when connecting to IRC. Until miniirc v2.0.0, you should only modify this while disconnected, as it is currently automatically updated with nickname changes. |
        
        The following arguments passed to `miniirc.IRC` are also available: `ip`,
        `port`, `channels`, `ssl`, `ident`, `realname`, `persist`, `connect_modes`,
        `quit_message`, `ping_interval`, `verify_ssl`.
        
        ## Handlers
        
        `miniirc.Handler` and `miniirc.CmdHandler` are function decorators that add
        functions to an event handler list. Functions in this list are called in their
        own thread when their respective IRC event(s) is/are received. Handlers may
        work on every IRC object in existence (`miniirc.Handler`) or only on
        specific IRC objects (`irc.Handler`).
        
        The basic syntax for a handler is as followed, where `*events` is a list of events (`PRIVMSG`, `NOTICE`, etc) are called.
        
        ~~~py
        import miniirc
        @miniirc.Handler(*events, colon=False)
        def handler(irc, hostmask, args):
            # irc:      An 'IRC' object.
            # hostmask: A 'hostmask' object.
            # args:     A list containing the arguments sent to the command. Everything
            #             following the first `:` in the command is put into one item
            #             (args[-1]). If "colon" is "False", the leading ":" (if any)
            #             is automatically removed. To prevent your code from horribly
            #             breaking, always set it to False unless you know what you are
            #             doing.
            pass
        ~~~
        
        #### Recommendations when using handlers:
        
         - If you don't need support for miniirc <1.4.0 and are parsing the last
            parameter, setting `colon` to `False` is strongly recommended. If the
            `colon` parameter is omitted, it defaults to `True`, however this will
            change when miniirc v2.0.0 is released.
         - Although `Handler` and `CmdHandler` currently accept any object that can be
            converted to a string, every event is converted to a string internally.
         - Not specifying the [`ircv3`](#ircv3-tags) parameter when it is not required
            prevents a redundant `dict` from being created.
         - To add handlers to a specific `IRC` object and not every one in existence,
            use `irc.Handler` and `irc.CmdHandler` instead. If you want to create a
            `Bot` or `Client` class and automatically add handlers to `IRC` objects
            created inside it, see
            [making existing functions handlers](#making-existing-functions-handlers).
        
        ### Hostmask object
        
        Hostmasks are tuples with the format `('user', 'ident', 'hostname')`. If `ident`
        and `hostname` aren't sent from the server, they will be filled in with the
        previous value. If a command is received without a hostmask, all the `hostmask`
        elements will be set to the name of the command. This is deprecated, however,
        and when miniirc v2.0.0 is released the `hostmask` elements will be set to
        empty strings.
        
        ### Making existing functions handlers
        
        You can make existing functions handlers (for example class instance methods)
        with `irc.Handler(*events)(handler_function)`. You probably don't want to use
        `miniirc.Handler` for class instance methods, as this will create a handler
        that gets triggered for every `IRC` object.
        
        You can also add multiple handlers of the same type easily:
        
        ```py
        add_handler = irc.Handler('PRIVMSG', colon=False)
        add_handler(handler_1)
        add_handler(self.instance_handler)
        ```
        
        This is useful if you want to create a `Bot` (or `Client`) class and add
        class-specific handlers without creating global process-wide handlers or
        creating a wrapper function for every class instance.
        
        ### IRCv3 support
        
        #### IRCv3 tags
        
        If you want your handler to support IRCv3 message tags, you need to add
        `ircv3=True` to the `Handler` or `CmdHandler` decorator. You will need to add a
        `tags` parameter to your function after `hostmask`. IRCv3 tags are sent to the
        handlers as `dict`s, with values of either strings or `True`.
        
        *miniirc will automatically un-escape IRCv3 tag values.*
        
        ~~~py
        import miniirc
        @miniirc.Handler(*events, colon=False, ircv3=True)
        def handler(irc, hostmask, tags, args):
            pass
        ~~~
        
        #### IRCv3 capabilities
        
        You can handle IRCv3 capabilities before connecting using a handler.
        You must use `force=True` on any `irc.quote()` called here, as when this is
        called, miniirc may not yet be fully connected. Do not use the `colon` argument
        for `Handler` when creating these handlers to avoid unexpected side-effects.
        
        ~~~py
        import miniirc
        @miniirc.Handler('IRCv3 my-cap-name')
        def handler(irc, hostmask, args):
            # Process the capability here
        
            # IRCv3.2 capabilities:
            #   args = ['my-cap-name', 'IRCv3.2-parameters']
        
            # IRCv3.1 capabilities:
            #   args = ['my-cap-name']
        
            # Remove the capability from the processing list.
            irc.finish_negotiation(args[0]) # This can also be 'my-cap-name'.
        ~~~
        
        ### Custom message parsers
        
        If the IRC server you are connecting to supports a non-standard message syntax, you can
        create custom message parsers. These are called with the raw message (as a `str`) and
        can either return `None` to ignore the message or a 4-tuple (`cmd, hostmask, tags, args`)
        that will then be sent on to the handlers. The items in this 4-tuple should be the same
        type as the items expected by handlers (and `cmd` should be a string).
        
        #### Message parser example
        
        This message parser makes the normal parser allow `~` as an IRCv3 tag prefix character.
        
        ~~~py
        import miniirc
        
        def my_message_parser(msg):
            if msg.startswith('~'):
                msg = '@' + msg[1:]
            return miniirc.ircv3_message_parser(msg)
        ~~~
        
        #### Changing message parsers
        
        To change message parsers, you can use `irc.change_parser(func=...)`. If `func` is not
        specified, it will default to the built-in parser. You can only change message parsers
        on-the-fly (for example in an IRCv3 CAP handler). If you need to change message parsers
        before connecting, you can disable `auto_connect` and change it then.
        
        ~~~py
        irc = miniirc.IRC(..., auto_connect=False)
        irc.change_parser(my_message_parser)
        irc.connect()
        ~~~
        
        ### Handling multiple events
        
        If you want to handle multiple events and/or be able to get the name of the
        event being triggered, you can use `irc.CmdHandler`. This will pass an extra
        `command` argument to the handler function (between `irc` and `hostmask`),
        containing a string with the command name (such as `PRIVMSG`).
        
        #### Catch-all handlers
        
        **Please do not use these unless there is no other alternative.**
        
        If you want to handle *every* event, you can use catch-all handlers. To create
        these, you can call `irc.CmdHandler()` *without* any parameters. Note that this
        handler will be called many times while connecting (and once connected).
        
        *You cannot call `irc.Handler()` without parameters.*
        
        ### Example
        
        ~~~py
        import miniirc
        
        # Not required, however this makes sure miniirc isn't insanely outdated.
        assert miniirc.ver >= (1,4,3)
        
        @miniirc.Handler('PRIVMSG', 'NOTICE', colon=True)
        def handler(irc, hostmask, args):
            print(hostmask[0], 'sent a message to', args[0], 'with content', args[1])
            # nickname sent a message to #channel with content :Hello, world!
        
        @miniirc.CmdHandler('PRIVMSG', 'NOTICE', colon=False)
        def cmdhandler(irc, command, hostmask, args):
            print(hostmask[0], 'sent a', command, 'to', args[0], 'with content',
                args[1])
            # nickname sent a PRIVMSG to #channel with content Hello, world!
        ~~~
        
        This will print a line whenever the bot gets a `PRIVMSG` or `NOTICE`.
        
        ## Misc functions
        
        miniirc provides the following helper functions:
        
        | Name                          | Description                               |
        | ----------------------------- | ----------------------------------------- |
        | `miniirc.get_ca_certs()`      | Runs `certifi.where()` if `certifi` is installed, otherwise returns `None`. |
        | `miniirc.ircv3_message_parser(msg)` | The default IRCv2/IRCv3 message parser, returns `cmd, hostmask, tags, args`. |
        | `miniirc.ver`                 | A tuple containing version information.   |
        | `miniirc.version`             | The `CTCP VERSION` reply, can be changed. |
        
        The version numbering system should be similar to [SemVer](https://semver.org/),
        however backwards compatibility is preserved where possible when major releases
        change. Patch version numbers can and will increase quickly, as miniirc is (at
        the time of writing this) under active development.
        
        ## Python version support
        
         - Python 2 does not work and will (probably) never work with miniirc. If you
            MUST use Python 2, you could try manually porting miniirc.
         - Python 3.3 and below probably won't work, and fixes will not be added unless
            they are very trivial.
         - Python 3.4 support will be dropped in miniirc v2.1.0 (miniirc v2.0.0 will
             have backported bugfixes for a few months).
         - Python 3.5, although not recommended, should work, however it is not tested
             as thoroughly as more recent versions.
         - Python 3.6 and above should work with the latest stable version of miniirc.
        
        If there is a bug/error in Python 3.4 or newer, please open an issue or pull
        request on [GitHub](https://github.com/luk3yx/miniirc/issues) or
        [GitLab](https://gitlab.com/luk3yx/miniirc/issues).
        
        *If you are using Python 3.5 or an older version of Python, I strongly
        recommend updating. Later versions of Python include features such as f-strings
        that make software development easier.*
        
        ## miniirc_extras
        
        If you want more advanced(-ish) features such as user tracking, you can use
        [miniirc_extras](https://pypi.org/project/miniirc-extras/)
        ([GitHub](https://github.com/luk3yx/miniirc_extras),

        is still in beta and there will be breaking API changes in the future.
        
        ## Deprecations
        
        When miniirc v2.0.0 is released, the following breaking changes will (probably)
        be made:
        
         - Internal-only attributes `irc.handlers`, `irc.sock`, and `irc.sendq`
            (please do not use these) will be renamed. Again, please do not use these.
         - `irc.nick` will be the nickname used when connecting to IRC rather than the
            current nickname, use `irc.current_nick` for the current nickname (since
            v1.4.3). This will stop lots of underscores being automatically appended to
            nicknames.
         - `irc.ns_identity` will be stored as a tuple instead of a string, for example
            `('username', 'password with spaces')` instead of
            `'username password with spaces'`. Both formats are currently accepted and
            will be accepted in the `ns_identity` keyword argument.
         - No exceptions will be raised in `irc.quote`/`irc.send` with `force=True`
            when the socket is closed. Instead of relying on these exceptions, use
            `irc.connected` which is set to `None` when completely disconnected.
         - As stated in the Python version support section, Python 3.4 support will be
            dropped in miniirc v2.1.0, however bugfixes will be backported for a few
            months.
         - The `colon` keyword argument to `Handler` and `CmdHandler` will default to
            `False` instead of `True`.
         - Unspecified hostmasks will be an empty string instead of the command. Don't
            rely on this "feature" if possible, simply ignore the hostmask if you do
            not need it.
         - The `extended-join` capability will be requested by default, use `args[0]`
            instead of `args[-1]` to get the channel from a `JOIN` event.
         - The `tags` keyword argument will be read-only.
        
        ## Working examples/implementations
        
        Here is a list of some (open-source) bots using miniirc, in alphabetical order:
        
         - [irc-rss-feed-bot] - Posts RSS entry titles and shortened URLs to IRC
            channels. *Python 3.8+*
         - [irc-url-title-bot] - Gets webpage titles from URLs posted in IRC channels.
            *Python 3.8+*
         - [lurklite] - A generic configurable IRC bot.
            *[GitHub](https://github.com/luk3yx/lurklite) link.*
         - [stdinbot] - A very simple bot that dumps stdin to an IRC channel.
            *[GitHub](https://github.com/luk3yx/stdinbot) link.*
