#Gocolorize Gocolorize is a package that allows Go programs to provide ANSI coloring in a stateful manner. Gocolorize is ideal for logging or cli applications.

##Features

• Stateful ANSI coloring
• Supports Foreground and background colors
• Supports a nuber of text properties such as bold or underline
• Color multiple arguments
• Color multiple interfaces, including complex types
• Tests with 100% coverage
• Working examples
• Disable ability for portability

##Install Gocolorize To install:

$ go get github.com/agtorre/gocolorize

##Usage Ways to initialize a Colorize object:

    //It can be done like this
    var c gocolorize.Colorize
    c.SetFg(gocolorize.Red)
    c.SetBg(gocolorize.Black)
    
    //Or this
    c := gocolorize.Colorize{Fg: gocolorize.Red, Bg: gocolorize.Black}
    
    //Or this
    c := gocolorize.NewColor("red:black")
    

Once you have an object:

    //Call Paint to take inputs and return a colored string
    c.Paint("This", "accepts", "multiple", "arguments", "and", "types:", 1, 1.25, "etc")

    //If you want a short-hand closure
    p = c.Paint
    p("Neat")

    //To print it:
    Fmt.Println(p("test"))
    
    //It can also be appended to other strings, used in logging to stdout, etc.
    a := "test " + p("case")

    //The closure allows you to reuse the original object, for example
    p = c.Paint
    c.SetFg(gocolorize.Green)
    p2 = c.Paint
    Fmt.Println(p("different" + " " + p2("colors")))

Object Properties:

    //These will only apply if there is a Fg and Bg respectively
    c.ToggleFgIntensity()
    c.ToggleBgIntensity()
    
    //Set additional attributes
    c.ToggleBold()
    c.ToggleBlink()
    c.ToggleUnderLine()
    c.ToggleInverse()

    //To disable or renable everything color (for example on Windows)
    //the other functions will still work, they'll just return plain
    //text for portability
    gocolorize.SetPlain(true)

##NewColor String Format

"foregroundColor+attributes:backgroundColor+attributes"

Colors:

• black
• red
• green
• yellow
• blue
• magenta
• cyan
• white

Attributes:

• b = bold foreground
• B = blink foreground
• u = underline foreground
• h = high intensity (bright) foreground, background
• i = inverse

##Examples See examples directory for examples:

$ cd examples/
$ go run song.go
$ go run logging.go

##Tests Tests are another good place to see examples. In order to run tests:

$ go test -cover

##Portability ANSI coloring will not work in default Windows environments and may not work in other environments correctly. In order to allow compatibility with these environments, you can call:

gocolorize.SetPlain(true)

Once toggled, the library will still function, but it will not color the output.

Special Thanks

https://github.com/mgutz/ansi was an inspiration for the latest version. I did a lot of rewriting, removed the 'paints' module, and did a lot of general cleanup. I learned a lot reading this and using this code.
