Defines and conditional config

You can define variables in the configuration file and use these variables elsewhere in the configuration file. You can also use this for conditional configuration. This can be used by advanced users, especially when sharing settings between servers and trying to use the same configuration files for all your servers.

Defining variables
You can define variables, like: @define $SERVER "hub.example.org"

Using variables
Anywhere in the configuration file you can refer to $VARIABLENAME. For example: me { name "$SERVER"; info "TestNET Server ($SERVER)"; sid 001; }

Conditional configuration
You can use @if to activate/deactivate configuration depending on conditions: @if $SERVER == "hub.example.org" link { [..] } @endif

There are only a few operations supported, namely:

The help.conf shipped with UnrealIRCd uses  so   only displays certain lines if the module is actually loaded: helpop chmodes { [..] @if module-loaded("chanmodes/noctcp") " C = No CTCPs allowed in the channel [h]"; @endif }
