InspIRCd v4 is still early in development!
If you use this branch you may experience crashes, weird behaviour, and unannounced breaking changes.
You probably want to use InspIRCd v3 instead.
Channel Modes
This page documents channel modes. For user modes see the user mode page.
InspIRCd supports five types of mode:
| Type | Parameter when adding? | Parameter when removing? | Can be set multiple times? | Description |
|---|---|---|---|---|
| Switch | No | No | No | Toggles the behaviour of a feature on a channel or user. |
| Parameter | Yes | No | No | Enables and configures the behaviour of a feature on a channel or user. |
| ParamBoth | Yes | Yes | No | The same as a Parameter mode only the parameter must be specified to remove it. |
| Prefix | Yes; channel member nickname | Yes; channel member nickname | Yes; once per channel member | Grants/revokes a status rank to the user specified in the parameter. |
| List | Yes | Yes | Yes; up to the maximum list size | Adds/removes entries from a list. |
Core
Core channel modes are channel modes which are always available. For details on the channel modes provided by modules, see the modules section below.
