## What it is
A Go library that provides a colored pretty printer for Go data structures, with fmt-like API functions such as Print, Println, Sprint, and Fprintf. It supports customizable color schemes, per-instance configuration, and works on Windows.

## Use cases
- pretty print Go data structures for debugging
- print maps and structs with colors in the terminal
- replace fmt.Println with a more readable debug printer
- customize syntax highlighting colors for printed output
- print only exported fields or omit empty fields

## When to avoid
- you need structured machine-readable output like JSON rather than human-readable terminal output
- you need a general-purpose logging framework with levels and sinks

## Facets
- artifact type: library
- maturity: stable
- function: developer-tools, logging
- domain: developer-tools
- platform: go, cross-platform
- tags: pretty-printer, debugging, syntax-highlighting, colored-output, command-line
