Advanced Configuration for PyLink Relay

PyLink Relay provides a few configuration options not documented in the example configuration, either because they have limited use or are too complicated to be described briefly.

This guide assumes that you are relatively familiar with the way YAML syntax works (lists, named arrays/dicts, etc.). In this document, configuration options will be referred to in the format a::b::c, which represents the “c” option inside a “b” config block, all within an “a” config block.

In actual YAML, that translates to this:

a:
    b:
        c: "some value"

Custom Clientbot Styles

Custom Clientbot styles can be applied for any of Clientbot’s supported events, by defining keys in the format relay::clientbot_styles::<event name>. As of 2.0-beta1, you can also set this per-network by defining options in the form servers::<network name>::relay_clientbot_styles::<event names> (Note: defining Clientbot styles locally will override the global clientbot_styles block and cause all values under it to be ignored for that network).

See below for a list of supported events and their default values (as of 2.0-beta1).

A common use case for this feature is to turn off or adjust colors/formatting; this is explicitly documented below.

These options take template strings as documented here: https://docs.python.org/3/library/string.html#template-strings. Supported substitution values differ by event, but usually include the hook values for each, plus the following:

• For all events:
  • $netname: origin network name
  • $sender: nick of sender
  • $sender_identhost: ident@host string of the sender
  • $colored_sender: color hashed version of $sender
  • $colored_netname: color hashed version of $netname
• For KICK, and other events that have a $target field corresponding to a user:
  • $target_nick: the nick of the target (as opposed to $target, which is an user ID)
• For events that have a $channel field attached (e.g. JOIN, PART):
  • $local_channel: the local channel name (i.e. the channel on the clientbot network)
  • $channel: the real channel name on the sender’s network
  • $mode_prefix: the highest prefix mode of the sender, if they are a user. This is normally either empty or one of (common prefix modes) ~&!@%+.
• For SJOIN, SQUIT:
  • $nicks: a comma-joined list of nicks that were bursted
  • $colored_nicks: a comma-joined list of each bursted nick, color hashed

To disable relaying for any specific event, set the template string to an empty string ('').

List of supported events

Event name	Default value
MESSAGE	[colored\_netname]\x02 <colored_sender> text KICK | \x02[colored_netname] - colored_sendersender_identhost has kicked $target_nick from channel (text)
PART	[$colored_netname] - colored_sendersender_identhost has left channel (text)
JOIN	[$colored_netname] - colored_sendersender_identhost has joined channel NICK | \x02[colored_netname] - colored_sendersender_identhost is now known as newnick QUIT | \x02[colored_netname] - colored_sendersender_identhost has quit (text) ACTION | \x02[colored_netname] * $colored_sender text NOTICE | \x02[colored_netname] - Notice from $colored_sender: text SQUIT | \x02[colored_netname] - Netsplit lost users: colored\_nicks SJOIN | \x02[colored_netname] - Netjoin gained users: $colored_nicks
PM	PM from $sender on $netname: text PNOTICE | <sender> $text

• Note: the PM and PNOTICE events represent private messages and private notices respectively, when they’re relayed to users behind a Clientbot link.
• Note 2: as of 1.1.x, all public channel events are sent to channels as PRIVMSG, while PM and PNOTICE are relayed privately as NOTICE.

Disabling Colors/Control Codes

If you don’t want the messages PyLink sends for clientbot messages to be emboldened or colored, remove all escape sequences (e.g. \x02) from the format template and replace the colored variants of applicable substitutions with their non-colored versions.

This is a example clientbot_styles config block, which you can copy into your relay configuration block. (Do not make multiple relay config blocks, or duplicate any config blocks with the same name!)

    clientbot_styles:
        ACTION: "[$netname] * $sender $text"
        JOIN: "[$netname] - $sender$sender_identhost has joined $channel"
        KICK: "[$netname] - $sender$sender_identhost has kicked $target_nick from $channel ($text)"
        MESSAGE: "[$netname] <$sender> $text"
        NICK: "[$netname] - $sender$sender_identhost is now known as $newnick"
        NOTICE: "[$netname] - Notice from $sender: $text"
        PART: "[$netname] - $sender$sender_identhost has left $channel ($text)"
        PM: "PM from $sender on $netname: $text"
        PNOTICE: "<$sender> $text"
        QUIT: "[$netname] - $sender$sender_identhost has quit ($text)"
        SJOIN: "[$netname] - Netjoin gained users: $nicks"
        SQUIT: "[$netname] - Netsplit lost users: $nicks"

Misc. options

• relay::clientbot_startup_delay: Defines the amount of seconds Clientbot should wait after startup, before relaying any non-PRIVMSG events. This is used to prevent excess floods when the bot connects. Defaults to 5 seconds.
• servers::NETNAME::relay_force_slashes: This network specific option forces Relay to use / in nickname separators. You should only use this option on TS6 or P10 variants that are less strict with nickname validation, as it will cause protocol violations on most IRCds. UnrealIRCd and InspIRCd users do not need to set this either, as / in nicks is automatically enabled.
• servers::NETNAME::relay_endburst_delay: InspIRCd networks only: sets the endburst delay for relay subservers. If relay server bursts are causing +j (join flood) protection to trigger, raising this value can work around the issue.
