color

Color lets you use colorized outputs in terms of ANSI Escape Codes in Go (Golang). It has support for Windows too! The API can be used in several ways, pick one that suits you. There might be a case where you want to explicitly disable/enable color output. the go-isatty package will automatically disable color output for non-tty output streams (for example if the output were piped directly to less). The color package also disables color output if the NO_COLOR environment variable is set (regardless of its value). Color has support to disable/enable colors programatically both globally and for single color definitions. For example suppose you have a CLI app and a --no-color bool flag. It also has support for single color definitions (local). You can disable/enable color output on the fly. To output color in GitHub Actions (or other CI systems that support ANSI colors), make sure to set color.NoColor = false so that it bypasses the check for non-tty output streams.
