# 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
|
|
```
|
