go-colortext package [](http://go-search.org/view?id=github.com%2Fdaviddengcn%2Fgo-colortext)
|
||||
====================
|
||||
|
||||
This is a package to change the color of the text and background in the console, working both under Windows and other systems.
|
||||
|
||||
Under Windows, the console APIs are used. Otherwise, ANSI texts are output.
|
||||
|
||||
Docs: http://godoc.org/github.com/daviddengcn/go-colortext ([packages that import ct](http://go-search.org/view?id=github.com%2fdaviddengcn%2fgo-colortext))
|
||||
|
||||
Usage:
|
||||
```go
|
||||
ct.Foreground(Green, false)
|
||||
fmt.Println("Green text starts here...")
|
||||
ct.ChangeColor(Red, true, White, false)
|
||||
fmt.Println(...)
|
||||
ct.ResetColor()
|
||||
```
