twisted.words.protocols.irc.ServerSupportedFeatures : API documentation

Handle ISUPPORT messages.

Feature names match those in the ISUPPORT RFC draft identically.

def __init__(self): (source)

Undocumented

@classmethod
def _splitParamArgs(cls, params, valueProcessor=None): (source)

Split ISUPPORT parameter arguments.

Values can optionally be processed by valueProcessor.

For example:

   >>> ServerSupportedFeatures._splitParamArgs(['A:1', 'B:2'])
   (('A', '1'), ('B', '2'))

Parameters	valueProcessor	Callable to process argument values, or `None` to perform no processing (type: `callable` taking {str})
Returns	Sequence of `(name, processedValue)` (type: `list` of `(str, object)`)

@classmethod
def _unescapeParamValue(cls, value): (source)

Unescape an ISUPPORT parameter.

The only form of supported escape is \xHH, where HH must be a valid 2-digit hexadecimal number.

Returns (type: str)

@classmethod
def _splitParam(cls, param): (source)

Split an ISUPPORT parameter.

Returns (type: (str, list) @return (key, arguments))

@classmethod
def _parsePrefixParam(cls, prefix): (source)

Parse the ISUPPORT "PREFIX" parameter.

The order in which the parameter arguments appear is significant, the earlier a mode appears the more privileges it gives.

Returns A dictionary mapping a mode character to a two-tuple of C({symbol, priority)}, the lower a priority (the lowest being 0) the more privileges it gives (type: dict mapping str to (str, int))

@classmethod
def _parseChanModesParam(self, params): (source)

Parse the ISUPPORT "CHANMODES" parameter.

See isupport_CHANMODES for a detailed explanation of this parameter.

def getFeature(self, feature, default=None): (source)

Get a server supported feature's value.

A feature with the value None is equivalent to the feature being unsupported.

Parameters	feature	Feature name (type: `str`)
	default	The value to default to, assuming that `feature` is not supported (type: `object`)
Returns	Feature value

def hasFeature(self, feature): (source)

Determine whether a feature is supported or not.

Returns (type: bool)

def parse(self, params): (source)

Parse ISUPPORT parameters.

If an unknown parameter is encountered, it is simply added to the dictionary, keyed by its name, as a tuple of the parameters provided.

Parameters params Iterable of ISUPPORT parameters to parse (type: iterable of str)

def isupport_unknown(self, command, params): (source)

Unknown ISUPPORT parameter.

def isupport_CHANLIMIT(self, params): (source)

The maximum number of each channel type a user may join.

def isupport_CHANMODES(self, params): (source)

Available channel modes.

There are 4 categories of channel mode:

   addressModes - Modes that add or remove an address to or from a
   list, these modes always take a parameter.

   param - Modes that change a setting on a channel, these modes
   always take a parameter.

   setParam - Modes that change a setting on a channel, these modes
   only take a parameter when being set.

   noParam - Modes that change a setting on a channel, these modes
   never take a parameter.

def isupport_CHANNELLEN(self, params): (source)

Maximum length of a channel name a client may create.

def isupport_CHANTYPES(self, params): (source)

Valid channel prefixes.

def isupport_EXCEPTS(self, params): (source)

Mode character for "ban exceptions".

The presence of this parameter indicates that the server supports this functionality.

def isupport_IDCHAN(self, params): (source)

Safe channel identifiers.

The presence of this parameter indicates that the server supports this functionality.

def isupport_INVEX(self, params): (source)

Mode character for "invite exceptions".

The presence of this parameter indicates that the server supports this functionality.

def isupport_KICKLEN(self, params): (source)

Maximum length of a kick message a client may provide.

def isupport_MAXLIST(self, params): (source)

Maximum number of "list modes" a client may set on a channel at once.

List modes are identified by the "addressModes" key in CHANMODES.

def isupport_MODES(self, params): (source)

Maximum number of modes accepting parameters that may be sent, by a client, in a single MODE command.

def isupport_NETWORK(self, params): (source)

IRC network name.

def isupport_NICKLEN(self, params): (source)

Maximum length of a nickname the client may use.

def isupport_PREFIX(self, params): (source)

Mapping of channel modes that clients may have to status flags.

def isupport_SAFELIST(self, params): (source)

Flag indicating that a client may request a LIST without being disconnected due to the large amount of data generated.

def isupport_STATUSMSG(self, params): (source)

The server supports sending messages to only to clients on a channel with a specific status.

def isupport_TARGMAX(self, params): (source)

Maximum number of targets allowable for commands that accept multiple targets.

def isupport_TOPICLEN(self, params): (source)

Maximum length of a topic that may be set.
