Either use a better terminal or perhaps try this: https://github.com/adoxa/ansicon

Links: http://code.dlang.org/packages/colorize https://github.com/yamadapc/d-colorize https://github.com/fazibear/colorize It's nice, but it could be more efficient. You usually use colors as a one-time shot to then output something to the terminal. For example in Ruby it would be: puts "hello".colorize.red.on_blue In Ruby it's implemented using regular expressions, very ugly and not very performant. In D you implemented it as returning another string that contains the format, which allocates a new string that is short lived. In Crystal we make colorize return a struct that wraps the original value but contains the color information. Then when that struct is converted to a string it appends the color codes to the output. In Crystal there's to_s (similar to toString()) but also to_s(io), which subclasses must override to append something to the given IO. That way memory allocations are reduced drastically without needing to create intermediate strings. Here's the source code and some specs if you feel like copying this idea: https://github.com/manastech/crystal/blob/master/src/colorize.cr https://github.com/manastech/crystal/blob/master/spec/std/colorize_spec.cr Also, usually the color is known by the user and not something that is put in a variable and later read. So having convenience methods that don't do a big case over the color or an enum value is again more performant. Something like: "hello".colorize.red instead of: "hello".colorize(fg.red) which is shorter, more readable *and* more efficient. You could generate those methods at compile time based on all the colors (which is something we do in Crystal too). Finally, don't restrict "colorize" to a string. You could colorize any object: # works, without converting [1, 2, 3] to a string puts [1, 2, 3].colorize.red

I've made a simple port of ruby's colorize library for D. I'd greatly appreciate any feedback. Windows isn't supported, yet. Cool! Would it be hard to add windows support?
