Activate conda environments in new shell processes.

conda spawn is a replacement subcommand for the conda activate and conda deactivate workflow

Instead of writing state to your current shell session, conda spawn ENV-NAME will start a new shell with your activated environment. To deactivate, exit the process with Ctrl+D, or run the command exit.

This is a conda plugin and goes in the base environment:

conda install -n base conda-forge::conda-spawn

More information is available on our documentation.

conda-spawn distinguishes two tiers of shell support:

• Fully supported: bash, zsh, powershell, cmd. Implemented in conda_spawn.shell. Covered by CI on every push and actively maintained.
• Best-effort: fish, csh/tcsh, xonsh. Implemented in conda_spawn.contrib. Provided to match conda activate's own activator coverage so conda-spawn can replace it on systems that use those shells. They are lightly tested and we rely on user reports to catch shell-specific bugs.
