:py:mod:`manager` ================= .. py:module:: conda.plugins.manager .. autoapi-nested-parse:: This module contains a subclass implementation of pluggy's `PluginManager `_. Additionally, it contains a function we use to construct the ``PluginManager`` object and register all plugins during conda's startup process. Classes ------- .. autoapisummary:: conda.plugins.manager.CondaPluginManager Functions --------- .. autoapisummary:: conda.plugins.manager.get_plugin_manager .. py:class:: CondaPluginManager(project_name: str | None = None, *args, **kwargs) Bases: :py:obj:`pluggy.PluginManager` The conda plugin manager to implement behavior additional to pluggy's default plugin manager. .. py:attribute:: get_cached_solver_backend .. py:method:: get_canonical_name(plugin: object) -> str Return a canonical name for a plugin object. Note that a plugin may be registered under a different name specified by the caller of :meth:`register(plugin, name) `. To obtain the name of a registered plugin use :meth:`get_name(plugin) ` instead. .. py:method:: register(plugin, name: str | None = None) -> str | None Call :meth:`pluggy.PluginManager.register` and return the result or ignore errors raised, except ``ValueError``, which means the plugin had already been registered. .. py:method:: load_plugins(*plugins) -> int Load the provided list of plugins and fail gracefully on error. The provided list of plugins can either be classes or modules with :attr:`~conda.plugins.hookimpl`. .. py:method:: load_entrypoints(group: str, name: str | None = None) -> int Load modules from querying the specified setuptools ``group``. :param str group: Entry point group to load plugins. :param str name: If given, loads only plugins with the given ``name``. :rtype: int :return: The number of plugins loaded by this call. .. py:method:: get_hook_results(name: Literal[conda.plugins.subcommands]) -> list[conda.plugins.types.CondaSubcommand] get_hook_results(name: Literal[conda.plugins.virtual_packages]) -> list[conda.plugins.types.CondaVirtualPackage] get_hook_results(name: Literal[conda.plugins.solvers]) -> list[conda.plugins.types.CondaSolver] get_hook_results(name: Literal[pre_commands]) -> list[conda.plugins.types.CondaPreCommand] get_hook_results(name: Literal[post_commands]) -> list[conda.plugins.types.CondaPostCommand] get_hook_results(name: Literal[auth_handlers]) -> list[conda.plugins.types.CondaAuthHandler] get_hook_results(name: Literal[conda.plugins.subcommands.doctor.health_checks]) -> list[conda.plugins.types.CondaHealthCheck] get_hook_results(name: Literal[pre_solves]) -> list[conda.plugins.types.CondaPreSolve] get_hook_results(name: Literal[conda.plugins.post_solves]) -> list[conda.plugins.types.CondaPostSolve] get_hook_results(name: Literal[settings]) -> list[conda.plugins.types.CondaSetting] Return results of the plugin hooks with the given name and raise an error if there is a conflict. .. py:method:: get_solvers() -> dict[str, conda.plugins.types.CondaSolver] Return a mapping from solver name to solver class. .. py:method:: get_solver_backend(name: str | None = None) -> type[conda.core.solve.Solver] Get the solver backend with the given name (or fall back to the name provided in the context). See ``context.solver`` for more details. Please use the cached version of this method called :meth:`get_cached_solver_backend` for high-throughput code paths which is set up as a instance-specific LRU cache. .. py:method:: get_auth_handler(name: str) -> type[requests.auth.AuthBase] | None Get the auth handler with the given name or None .. py:method:: get_settings() -> dict[str, conda.common.configuration.ParameterLoader] Return a mapping of plugin setting name to ParameterLoader class This method intentionally overwrites any duplicates that may be present .. py:method:: invoke_pre_commands(command: str) -> None Invokes ``CondaPreCommand.action`` functions registered with ``conda_pre_commands``. :param command: name of the command that is currently being invoked .. py:method:: invoke_post_commands(command: str) -> None Invokes ``CondaPostCommand.action`` functions registered with ``conda_post_commands``. :param command: name of the command that is currently being invoked .. py:method:: disable_external_plugins() -> None Disables all currently registered plugins except built-in conda plugins .. py:method:: get_subcommands() -> dict[str, conda.plugins.types.CondaSubcommand] .. py:method:: get_virtual_packages() -> tuple[conda.plugins.types.CondaVirtualPackage, Ellipsis] .. py:method:: invoke_health_checks(prefix: str, verbose: bool) -> None .. py:method:: invoke_pre_solves(specs_to_add: frozenset[conda.models.match_spec.MatchSpec], specs_to_remove: frozenset[conda.models.match_spec.MatchSpec]) -> None Invokes ``CondaPreSolve.action`` functions registered with ``conda_pre_solves``. :param specs_to_add: :param specs_to_remove: .. py:method:: invoke_post_solves(repodata_fn: str, unlink_precs: tuple[conda.models.records.PackageRecord, Ellipsis], link_precs: tuple[conda.models.records.PackageRecord, Ellipsis]) -> None Invokes ``CondaPostSolve.action`` functions registered with ``conda_post_solves``. :param repodata_fn: :param unlink_precs: :param link_precs: .. py:method:: load_settings() -> None Iterates through all registered settings and adds them to the :class:`conda.common.configuration.PluginConfig` class. .. py:function:: get_plugin_manager() -> CondaPluginManager Get a cached version of the :class:`~conda.plugins.manager.CondaPluginManager` instance, with the built-in and entrypoints provided by the plugins loaded.
