It +gathers information about the terminal environment in terms of its ANSI & color +support and offers you convenient methods to colorize and style your output, +without you having to deal with all kinds of weird ANSI escape sequences and +color conversions. + +## Features + +- RGB/TrueColor support +- Detects the supported color range of your terminal +- Automatically converts colors to the best matching, available colors +- Terminal theme (light/dark) detection +- Chainable syntax +- Nested styles + +## Installation + +```bash +go get github.com/muesli/termenv +``` + +## Usage + +```go +output := termenv.NewOutput(os.Stdout) +``` + +`termenv` queries the terminal's capabilities it is running in, so you can +safely use advanced features, like RGB colors or ANSI styles. `output.Profile` +returns the supported profile: + +- `termenv.Ascii` - no ANSI support detected, ASCII only +- `termenv.ANSI` - 16 color ANSI support +- `termenv.ANSI256` - Extended 256 color ANSI support +- `termenv.TrueColor` - RGB/TrueColor support + +Alternatively, you can use `termenv.EnvColorProfile` which evaluates the +terminal like `ColorProfile`, but also respects the `NO_COLOR` and +`CLICOLOR_FORCE` environment variables. + +You can also query the terminal for its color scheme, so you know whether your +app is running in a light- or dark-themed environment: + +```go +// Returns terminal's foreground color +color := output.ForegroundColor() + +// Returns terminal's background color +color := output.BackgroundColor() + +// Returns whether terminal uses a dark-ish background +darkTheme := output.HasDarkBackground() +``` + +### Manual Profile Selection + +If you don't want to rely on the automatic detection, you can manually select +the profile you want to use: + +```go +output := termenv.NewOutput(os.Stdout, termenv.WithProfile(termenv.TrueColor)) +``` + +## Colors + +`termenv` supports multiple color profiles: Ascii (black & white only), +ANSI (16 colors), ANSI Extended (256 colors), and TrueColor (24-bit RGB).
