== [source:trunk/tracopt/perm/config_perm_provider.py tracopt.perm.config_perm_provider.ExtraPermissionsProvider] Optional component which makes it possible to easily add new permissions to a Trac environment. These can be used for example in configurable [wiki:TracWorkflow]s, when one wants to add a permission specific to a transition, via the `.permissions` key. To add new permissions, create a new section `[extra-permissions]` in [TracIni#extra-permissions-section trac.ini]. Every entry in that section defines a meta-permission and a comma-separated list of permissions. For example: {{{#!ini [extra-permissions] EXTRA_ADMIN = EXTRA_VIEW, EXTRA_MODIFY, EXTRA_DELETE }}} This entry will define three new permissions `EXTRA_VIEW`, `EXTRA_MODIFY` and `EXTRA_DELETE`, as well as a meta-permissions `EXTRA_ADMIN` that grants all three permissions. The permissions are created in upper-case characters regardless of the casing of the definitions in `trac.ini`. For example, the definition `extra_view` would create the permission `EXTRA_VIEW`. If you don't want a meta-permission, start the meta-name with an underscore (`_`): {{{#!ini [extra-permissions] _perms = EXTRA_VIEW, EXTRA_MODIFY }}} See also: #9392, [source:trunk/tracopt/perm/config_perm_provider.py#L18 config_perm_provider.py]
