Activate Environments in Terminal Using Environment Variables

Python extension now activates selected environment in terminal without sending any activation commands (#11039). Traditionally, terminal prompts are generally used to indicate whether a Python env is currently activated in terminal:

However now, in some cases, the indicator might not be present at all. Nonetheless, please be assured that the environment is still activated.

Pro tips:

• You can hover over the terminal tab to see which environment is currently activated in terminal:

  

• Click "Show environment contributions" if you're interested in which specific environment variables were applied to activate this terminal:

  

Limitations:

Such implicit activation will not work in the following case:

• You have shell integration turned off: "terminal.integrated.shellIntegration.enabled": false
• And your shell init script (.bashrc, profile.ps1 etc.) activates another environment (say myshellenv) for your shell. For eg. this can happen if "base" conda environment is activated by default: #20885.

In this case myshellenv will override the selected environment and terminal is activated using myshellenv instead. This can be solved for conda base case by running the following command and restarting your shell:

conda config --set auto_activate_base False
