Kotlin has no support for typeclasses. We’re trying out multiple approaches to see what is possible.

Nushell has a built-in command to invoke HTTP requests: http. You don’t need an external tool like curl or httpie to make HTTP requests. There a lot of options to use with the http command. One of them is the --full or shorter -f option to return a table with extra details of the HTTP request and response. The request and response headers, the body and status are returned in the table. You can easily get information from the table with all the default selection options for a table structure.

Sometimes it happens. You stumble upon something that feels brand new to you — only to find out it’s been around for years. When I joined Moderne and started working with its OpenRewrite framework, this exact thing happened. 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.
