Terminal activation notes

notes.txt

When terminal opens up:
- Process creation
- Intiialization scripts (.zshrc, .bashrc, Powershell profile)
    - conda init (activating base by default)
- Shell integration script
    - Fails silently
         - Powershell execution is disabled for windows
         - Automatic shell integration may not be working
    - Disables this script (based on shell config)

Variables that are prepended:
- PS1
- PATH


- (.zshrc, .bashrc, Powershell profile)

Environment activation:

- We have a selected environment that needs to be activated
- Get the environment variables that are needed to be set in temrinal, to activate this environment:
      - Launch a process
          - Activate env
          - Print environment variables (everything may contain process specific stuff (PROCESS: true)) (diff only contains the variables which are required to activate, HOME env variable)
          - Con: It does not run any shell initialization script (.zshrc, .bashrc, Powershell profile)
               - Suppose if user set a certain variable there, let's say to disable the terminal prompt (.venv)
        - Launch a terminal          - Activate env
          - Print environment variables
          - Get output from shell integration API
                 - Not as reliable (Daniel said)
          - We can know when the command finishes
        - Launch a terminal  (hidden terminal)
          - Activate env
          - Print environment variables to a file (not to stdout in terminal) (everything)
               - It does not contain any terminal prompt stuff
          - Get output from shell integration API
                 - Not as reliable (Daniel said)
          - We can know when the command finishes

How will you know whether shell integration is active?

- Once you detect shell integration is working (let's say for powershell), persist that info
     - Memento API

Mechansim to get output using hidden terminals:

- Just use one hidden terminal (because shell integration takes time to activate)
