It's often convenient to install editor integrations for CALC's languages to provide useful functionality like autocompletion and instant feedback from CALC's linters and type checkers. However, doing this often requires setting up CALC's JavaScript and/or Python environment on the host system, outside of Docker.
Setting up CALC's JavaScript environment can be accomplished by installing NodeJS and yarn and running the following on your local machine:
yarn install --ignore-engines
At this point, you should be able to install any editor integrations for JavaScript-related code, and they should work as expected.
Setting up CALC's Python environment can be accomplished by installing the version of Python 3 specified in runtime.txt. You can then install virtualenv:
python3 -m pip install virtualenv
Then you can create a virtualenv in the venv directory:
python3 -m venv venv
You can now activate the virtualenv; on OSX/Linux, this is done via:
source venv/bin/activate
Or if you're on Windows, use:
venv\Scripts\activate
Now you can install development requirements:
pip install -r requirements-dev.txt
At this point you can run your text editor, and any Python-related editor integrations you've installed should work as expected.
