This library provide a replacement to F# `printf` function with color support.

The syntax to set the color inside the string is `$foreground;background[text]` where both foreground and background

are optional.

The supported colors are the one from the [System.ConsoleColor](https://docs.microsoft.com/en-us/dotnet/api/system.consolecolor) enum.

## Examples

```fsharp

// Change the color of part of a string

colorprintfn "$red[Hello] $white;red[world]."

// Use sprintf syntax

colorprintfn "Hello $green[%s]: %s" "user" "Welcome to color!"

colorprintfn "$white[Progress]: $yellow[%.2f%%] (Eta $yellow[%i] minutes)" 42.33 5

// Use interpolated strings

let life = "La vie"

let is_ = "est"

colorprintfn $"""$white;blue[%s{life} ]$black;white[{is_} ]$white;red[{"belle"}]"""

// Specify the colors from variables

let logColor = ConsoleColor.Yellow

colorprintfn "result: $%A[Hello world]" logColor

colorprintfn $"result: ${logColor}[Hello world]"

```
