conda-env-manager: cenv
Due to the redundant dependency information inside the meta.yaml
(required
to create the conda-package) and the environment.yml
(as definition file
for the conda-environment during development and for production), cenv
(short form for conda-env-manager
) was created to make the meta.yaml
the only relevant file and to create and update conda-environment from the
definition inside this meta.yaml
.
The name of the conda-environment to create / update is defined in the section
extra
and the variable env_name
inside the meta.yaml
(at
conda-build/meta.yaml
).
The steps run by cenv:
- creation of a backup if the environment already exists followed by the removal of the previous environment.
- creation of the environment as defined in the
meta.yaml
. If any failures occurred during creation and the backup was created, the command to reset the backup-version can be used. - if enabled in the config file the environment.yml is exported after creation / update of the environment.
The usage of cenv reduces the conda commands to use to the following:
conda activate ...
to activate the environmentconda deactivate
to deactivate an environmentconda info
to show information about the currently activated environmentconda search ...
to search for availability of a package in the conda channels.conda remove -n ... --all
to remove an environmentcenv
to create / update an environment
