Further Information

gutenfmt is a also a Go library that helps to create applications, which support different output formats. It comes with an opinionated view of the third-party libraries, so that you can get started with minimum fuss. In other words, Formatters come with meaningful defaults.

The primary goals are:

• Provide a radically faster and widely accessible getting-started experience for Command Line Interface (CLI) development.
• Be opinionated out of the box but get out of the way quickly as requirements start to diverge from the defaults.
• Provide a range of standardized output formats that are common to state-of-the-art projects.
