Running demo on Windows

Hello! I found that if you run the demo using this line

cd kuwala/scripts && sh initialize_core_components.sh && sh run_cli.sh

On docker desktop for Windows, it founds an error:

sh: 0: Can't open build_neo4j.sh
sh: 0: Can't open build_cli.sh
build_jupyter_notebook.sh: 1: cd: can't cd to ..

[7178] Failed to execute script docker-compose

I assume that the bash script is not fully compatible with Windows filesystem… Any idea for this?

Thank you ^^

After discussing with @IritaSee, we found that the initialize_windows.sh script is not reproducible for all systems and still depends a lot on the local Windows setup. Therefore we decide to switch to a new approach to get Kuwala running on all the systems.

Instead of having .sh scripts, we will replace each of them with a Python script. Each Python script itself will have a main method and execute all the commands that are currently in the .sh scripts by using Python’s subprocess module.

For example, you can execute a command in a shell environment using this syntax:

 process = subprocess.Popen(['docker-compose build postgres'], bufsize=1, stdout=subprocess.PIPE, stderr=subprocess.PIPE, universal_newlines=True, shell=True)

To change the working directory, you can use os.chdir(). Remember to always reeset the working directory at the start of each method. To get the path to the file the method is called from, use script_dir = os.path.dirname(__file__).

The demo is not running on Windows out of the box. The existing command cd kuwala/scripts && sh initialize_core_components.sh && sh run_cli.sh was designed for Mac/Linux.

The prerequisites stay the same. People have to have Python3 (along with pip) installed, have downloaded Docker Desktop and launched it in the background.

The necessary adjustments to get it running on Windows are:

1. Create a new script for windows in the manner of the one above that doesn’t use sh since that is not supported on Windows.
2. Activating the virtual environment likely uses a different command on Windows.
3. Some pip packages from the requirements.txt of the CLI might have Windows-specific issues.
