Using the virtual environment

1. Create the virtual environment:

    $ make create-venv SCADAJS_VENV_PATH=/path/to/somewhere/scadajs1
   

2. Activate and use it:

    $ export SCADAJS_VENV_PATH=/path/to/somewhere/scadajs1
    $ ./venv
    (scadajs1) $ 
   

Using a virtual environment for all or some ScadaJS projects

Set the SCADAJS_VENV_PATH to /path/to/existing/virtual-environment and use the ./scada.js/venv script to activate the virtual environment as usual.

Using virtual environment from within Tmux

1. (Optional) Set the SCADAJS_VENV_PATH variable for the TARGET_TMUX_SESSION:

tmux setenv -t ${TARGET_TMUX_SESSION} 'SCADAJS_VENV_PATH' /path/to/somewhere/scadajs1

2. On every new pane, manually activate your virtual environment by:

$ ./scada.js/venv
(scadajs1) $ 

By setting the Tmux's SCADAJS_VENV_PATH variable, ./scada.js/venv script uses this virtual environment by default. If you want to start a different virtual environment in your new pane:

$ ./scada.js/venv /path/to/your/other/virtual-environment
(something) $
