Nselfs 6lib/python3.12/site-packages/conda/plugins/hookspec.py conda_solverszCondaSpecs.conda_solvers2cy)a. Register external subcommands in conda. **Example:** .. code-block:: python from conda import plugins def example_command(args): print("This is an example command!") @plugins.hookimpl def conda_subcommands(): yield plugins.CondaSubcommand( name="example", summary="example command", action=example_command, ) :return: An iterable of subcommand entries. Nrrs rconda_subcommandszCondaSpecs.conda_subcommandsSrrcy)a Register virtual packages in Conda. **Example:** .. code-block:: python from conda import plugins @plugins.hookimpl def conda_virtual_packages(): yield plugins.CondaVirtualPackage( name="my_custom_os", version="1.2.3", build="x86_64", ) :return: An iterable of virtual package entries. Nrrs rconda_virtual_packagesz!CondaSpecs.conda_virtual_packagesnrrcy)a Register pre-command functions in conda. **Example:** .. code-block:: python from conda import plugins def example_pre_command(command): print("pre-command action") @plugins.hookimpl def conda_pre_commands(): yield plugins.CondaPreCommand( name="example-pre-command", action=example_pre_command, run_for={"install", "create"}, ) Nrrs rconda_pre_commandszCondaSpecs.conda_pre_commandsrrcy)a  Register post-command functions in conda. **Example:** .. code-block:: python from conda import plugins def example_post_command(command): print("post-command action") @plugins.hookimpl def conda_post_commands(): yield plugins.CondaPostCommand( name="example-post-command", action=example_post_command, run_for={"install", "create"}, ) Nrrs rconda_post_commandszCondaSpecs.conda_post_commandsrrcy)az Register a conda auth handler derived from the requests API. This plugin hook allows attaching requests auth handler subclasses, e.g. when authenticating requests against individual channels hosted at HTTP/HTTPS services. **Example:** .. code-block:: python import os from conda import plugins from requests.auth import AuthBase class EnvironmentHeaderAuth(AuthBase): def __init__(self, *args, **kwargs): self.username = os.environ["EXAMPLE_CONDA_AUTH_USERNAME"] self.password = os.environ["EXAMPLE_CONDA_AUTH_PASSWORD"] def __call__(self, request): request.headers["X-Username"] = self.username request.headers["X-Password"] = self.password return request @plugins.hookimpl def conda_auth_handlers(): yield plugins.CondaAuthHandler( name="environment-header-auth", auth_handler=EnvironmentHeaderAuth, ) Nrrs rconda_auth_handlerszCondaSpecs.conda_auth_handlersrrcy)a Register health checks for conda doctor. This plugin hook allows you to add more "health checks" to conda doctor that you can write to diagnose problems in your conda environment. Check out the health checks already shipped with conda for inspiration. **Example:** .. code-block:: python from conda import plugins def example_health_check(prefix: str, verbose: bool): print("This is an example health check!") @plugins.hookimpl def conda_health_checks(): yield plugins.CondaHealthCheck( name="example-health-check", action=example_health_check, ) Nrrs rconda_health_checkszCondaSpecs.conda_health_checksrrcy)a? Register pre-solve functions in conda that are used in the general solver API, before the solver processes the package specs in search of a solution. **Example:** .. code-block:: python from conda import plugins from conda.models.match_spec import MatchSpec def example_pre_solve( specs_to_add: frozenset[MatchSpec], specs_to_remove: frozenset[MatchSpec], ): print(f"Adding {len(specs_to_add)} packages") print(f"Removing {len(specs_to_remove)} packages") @plugins.hookimpl def conda_pre_solves(): yield plugins.CondaPreSolve( name="example-pre-solve", action=example_pre_solve, ) Nrrs rconda_pre_solveszCondaSpecs.conda_pre_solvesrrcy)a Register post-solve functions in conda that are used in the general solver API, after the solver has provided the package records to add or remove from the conda environment. **Example:** .. code-block:: python from conda import plugins from conda.models.records import PackageRecord def example_post_solve( repodata_fn: str, unlink_precs: tuple[PackageRecord, ...], link_precs: tuple[PackageRecord, ...], ): print(f"Uninstalling {len(unlink_precs)} packages") print(f"Installing {len(link_precs)} packages") @plugins.hookimpl def conda_post_solves(): yield plugins.CondaPostSolve( name="example-post-solve", action=example_post_solve, ) Nrrs rconda_post_solveszCondaSpecs.conda_post_solvesrrcy)a Register new setting The example below defines a simple string type parameter **Example:** .. code-block:: python from conda import plugins from conda.common.configuration import PrimitiveParameter, SequenceParameter @plugins.hookimpl def conda_settings(): yield plugins.CondaSetting( name="example_option", description="This is an example option", parameter=PrimitiveParameter("default_value", element_type=str), aliases=("example_option_alias",), ) Nrrs rconda_settingszCondaSpecs.conda_settings7rrN)returnzIterable[CondaSolver])r.zIterable[CondaSubcommand])r.zIterable[CondaVirtualPackage])r.zIterable[CondaPreCommand])r.zIterable[CondaPostCommand])r.zIterable[CondaAuthHandler])r.zIterable[CondaHealthCheck])r.zIterable[CondaPreSolve])r.zIterable[CondaPostSolve])r.zIterable[CondaSetting])__name__ __module__ __qualname____doc__ _hookspecrrrr!r#r%r'r)r+r-rrrrr/s?  @  4  ,  0  0" " H  6  <  >  rr)r2 __future__rtypingrpluggycollections.abcrtypesrrr r r r r rrr spec_nameHookspecMarkerr3HookimplMarkerhookimplrrrrr=sp# (     8 !F ! !) ,  !6  + _ _ r
