rainbow

Overview ¶

Package rainbow prints texts in beautiful rainbows in terminal. Usage is very simple:

import "github.com/arsham/rainbow/rainbow"
// ...
l := rainbow.Light{
    Reader: someReader, // to read from
    Writer: os.Stdout, // to write to
}
l.Paint() // will rainbow everything it reads from reader to writer.

If you want the rainbow to be random, you can seed it this way:

l := rainbow.Light{
    Reader: buf,
    Writer: os.Stdout,
    Seed:   rand.Int63n(256),
}

You can also use the Light as a Writer:

l := rainbow.Light{
    Writer: os.Stdout, // to write to
    Seed:   rand.Int63n(256),
}
io.Copy(l, someReader)
