goterminal

A cross-platform Go-library for updating progress in terminal.

Installation

  go get -u github.com/apoorvam/goterminal

Usage

    func main() {
        // get an instance of writer
        writer := goterminal.New()

        for i := 0; i < 100; i = i + 10 {
            // add your text to writer's buffer
            fmt.Fprintf(writer, "Downloading (%d/100) bytes...\n", i)
            // write to terminal
            writer.Print()
            time.Sleep(time.Millisecond * 200)

            // clear the text written by previous write, so that it can be re-written.
            writer.Clear()
        }

        // reset the writer
        writer.Reset()
        fmt.Println("Download finished!")
    }

Example

Another example which uses the go-colortext library to re-write text along with using colors. Here is output of example:

More on usage

• Create a Writer instance.
• Add your text to writer's buffer and call Print() to print text on Terminal. This can be called any number of times.
• Call Clear() to move the cursor to position where first Print() started so that it can be over-written.
• Reset() writer, so it clears its state for next Write.
