Expand description

ColorChoice represents the color preferences of an end user.

Variants

Always

Try very hard to emit colors. This includes emitting ANSI colors on Windows if the console API is unavailable.

AlwaysAnsi

AlwaysAnsi is like Always, except it never tries to use anything other than emitting ANSI color codes.

Auto

Try to use colors, but don’t force the issue. If the console isn’t available on Windows, or if TERM=dumb, or if NO_COLOR is defined, for example, then don’t use colors.

Never

Never emit colors.

Implementations

Returns true if we should attempt to write colored output.
