Usage

To analyze the code or view the wiki you can navigate to the src and tests or docs folder in this GitHub repository. Another option is to clone the repo into your machine, but be advised that the use will be limited for the lack of data.
To use the TUI, you would need a test environment with simulated data. We have set up a virtual machine for that. We also need your ssh key to give you access to the machine, you can email one of us for that. There you have two options, you can use already pulled source code and installed dependencies or you could try doing it yourself.

Using TUI in the Test VM with everything set up and installed:

• ssh into ubuntu@193.40.155.199
• Go to cd development/Waldur if you want to use already pulled code
• Run the TUI with poetry run python src/WaldurSA_TUI/main.py

Using TUI in the Test VM and setting everything up yourself:

• ssh into ubuntu@193.40.155.199
• Go to a review directory if you want to test pulling source code yourself
  • cd review/mentor if you are the mentor
  • cd review/peer if you are the peer reviewer
  • Clone the GitHub project and move into it with cd WaldurSA-TUI
    
• To run it from the source code, you'd need to install the following:
  • Install Poetry https://python-poetry.org/docs/#installing-with-pipx
  • Install libsystemd-dev sudo apt install libsystemd-dev
  • In the cloned project install Poetry dependencies with poetry install
    • If you encounter any errors related to cysystemd failing to install then run sudo apt-get install build-essential
  • Run the TUI with poetry run python src/WaldurSA_TUI/main.py
