PluginSetup

Abstract contract · src/common/plugin/setup/PluginSetup.sol

Explained in: Plugin setup

Author: Aragon X - 2022-2024

Inherits: ERC165, IPluginSetup, ProtocolVersion

An abstract contract to inherit from to implement the plugin setup for non-upgradeable plugins, i.e,

• Plugin being deployed via the new keyword
• PluginCloneable being deployed via the minimal proxy pattern (see ERC-1167).

Functions

implementation

function implementation() external view returns (address)

Selector: 0x5c60da1b

Returns the plugin implementation address.

Dev: The implementation can be instantiated via the new keyword, cloned via the minimal proxy pattern (see ERC-1167), or proxied via the UUPS proxy pattern (see ERC-1822).

Returns	Type	Description
[0]	address	The address of the plugin implementation contract.

prepareInstallation

function prepareInstallation(
    address _dao,
    bytes _data
) external returns (address plugin, IPluginSetup.PreparedSetupData preparedSetupData)

Selector: 0xf10832f1

Prepares the installation of a plugin.

Parameter	Type	Description
_dao	address	The address of the installing DAO.
_data	bytes	The bytes-encoded data containing the input parameters for the installation as specified in the plugin's build metadata JSON file.

Returns	Type	Description
plugin	address	The address of the Plugin contract being prepared for installation.
preparedSetupData	IPluginSetup.PreparedSetupData	The deployed plugin's relevant data which consists of helpers and permissions.

prepareUninstallation

function prepareUninstallation(
    address _dao,
    IPluginSetup.SetupPayload _payload
) external returns (PermissionLib.MultiTargetPermission[] permissions)

Selector: 0x9cb0a124

Prepares the uninstallation of a plugin.

Parameter	Type	Description
_dao	address	The address of the uninstalling DAO.
_payload	IPluginSetup.SetupPayload	The relevant data necessary for the prepareUninstallation. See above.

Returns	Type	Description
permissions	PermissionLib.MultiTargetPermission[]	The array of multi-targeted permission operations to be applied by the PluginSetupProcessor to the uninstalling DAO.

prepareUpdate

function prepareUpdate(
    address _dao,
    uint16 _fromBuild,
    IPluginSetup.SetupPayload _payload
) external returns (bytes, IPluginSetup.PreparedSetupData)

Selector: 0xa8a9c29e

Prepares the update of a plugin.

Dev: Since the underlying plugin is non-upgradeable, this non-virtual function must always revert.

Parameter	Type	Description
_dao	address	The address of the updating DAO.
_fromBuild	uint16	The build number of the plugin to update from.
_payload	IPluginSetup.SetupPayload	The relevant data necessary for the prepareUpdate. See above.

Returns	Type	Description
[0]	bytes	The initialization data to be passed to upgradeable contracts when the update is applied in the PluginSetupProcessor.
[1]	IPluginSetup.PreparedSetupData	The deployed plugin's relevant data which consists of helpers and permissions.

protocolVersion

function protocolVersion() external pure returns (uint8[3])

Selector: 0x2ae9c600

Returns the semantic Aragon OSx protocol version number that the implementing contract is associated with.

Dev: This version number is not to be confused with the release and build numbers found in the Version.Tag struct inside the PluginRepo contract being used to version plugin setup and associated plugin implementation contracts.

Returns	Type	Description
[0]	uint8[3]	Returns the semantic Aragon OSx protocol version number.

supportsInterface

function supportsInterface(bytes4 _interfaceId) external view returns (bool)

Selector: 0x01ffc9a7

Checks if this or the parent contract supports an interface by its ID.

Parameter	Type	Description
_interfaceId	bytes4	The ID of the interface.

Errors

NonUpgradeablePlugin

error NonUpgradeablePlugin()

Thrown when attempting to prepare an update on a non-upgradeable plugin.
