+# ansi
+
+Package ansi is a small, fast library to create ANSI colored strings and codes.
+
+## Install
+
+Get it
+
+```sh
+go get -u github.com/mgutz/ansi
+```
+
+## Example
+
+```go
+import "github.com/mgutz/ansi"
+
+// colorize a string, SLOW
+msg := ansi.Color("foo", "red+b:white")
+
+// create a FAST closure function to avoid computation of ANSI code
+phosphorize := ansi.ColorFunc("green+h:black")
+msg = phosphorize("Bring back the 80s!")
+msg2 := phospohorize("Look, I'm a CRT!")
+
+// cache escape codes and build strings manually
+lime := ansi.ColorCode("green+h:black")
+reset := ansi.ColorCode("reset")
+
+fmt.Println(lime, "Bring back the 80s!", reset)
+```
+
+Other examples
+
+```go
+Color(s, "red")            // red
+Color(s, "red+d")          // red dim
+Color(s, "red+b")          // red bold
+Color(s, "red+B")          // red blinking
+Color(s, "red+u")          // red underline
+Color(s, "red+bh")         // red bold bright
+Color(s, "red:white")      // red on white
+Color(s, "red+b:white+h")  // red bold on white bright
+Color(s, "red+B:white+h")  // red blink on white bright
+Color(s, "off")            // turn off ansi codes
+```
+
+To view color combinations, from project directory in terminal.
+
+```sh
+go test
+```
+
+## Style format
+
+```go
+"foregroundColor+attributes:backgroundColor+attributes"
+```
