Production environment

If you want to give a try to Kosmorro, head to its official download page and follow the instructions that correspond to your operating system.

Development environment

Before you run Kosmorro in your development environment, check you have installed these programs on your system:

Clone this repository and run poetry install to install all the dependencies. Then, run Kosmorro by invoking poetry run kosmorro.

For comfort, you may want to invoke poetry shell first and then just kosmorro.

Using Kosmorro

Using Kosmorro is as simple as invoking kosmorro in your terminal!

By default, it will give you the current Moon phase and, if any, the events that will occur today. To get the rise, culmination and set of the objects of the Solar system, you will need to give it your position on Earth: get your current coordinates (with OpenStreetMap for instance), and give them to Kosmorro by invoking it with the following parameters: --latitude=X --longitude=Y (replace X by the latitude and Y by the longitude).

Kosmorro has a lot of available options. To get a list of them, run kosmorro --help, or read its manual with man kosmorro.

Note: the first time it runs, Kosmorro will download some important files needed to make the computations. They are stored in a cache folder named .kosmorro-cache located in your home directory (/home/<username> on Linux, /Users/<username> on macOS).

Exporting to PDF

Kosmorro can export the computation results to PDF files, but this feature requires first that you install some additional dependencies. You can find documentation about this on Kosmorro’s website.
