Package ansi is a small, fast library to create ANSI colored strings and codes.
|
|
|
|
Installation
|
|
|
|
# this installs the color viewer and the package
|
|
go get -u github.com/mgutz/ansi/cmd/ansi-mgutz

Example
|
|
|
|
// colorize a string, SLOW
|
|
msg := ansi.Color("foo", "red+b:white")
|
|
|
|
// create a closure to avoid recalculating ANSI code compilation
|
|
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)
|
