The ultimate way to get rid of versioning administration is to use CI/CD (Continuous Integration/Continuous Deployment). However, in many cases CD is not possible. For example when creating libraries, or software requiring versions for compliance reasons. Versioning is then still needed.

You can easily get information from the table with all the default selection options for a table structure.

I discovered the Java Service Provider Interface (SPI), a native mechanism in Java that enables plugin-like extensibility in applications.

Nushell has a lot of commands to work with strings. The str kebab-case command can be used to convert a string to kebab case. Kebab-case is a string that contains only lowercase letters and words are separated by hyphens.
