# go-ncurses

**go-ncurses** is a wrapper for [go](https://www.golang.org) of the famous ncurses library.

```go

package ncurses

import ( 

	"fmt"

)

main() {

  w,_ := ncurses.Initscr()

  

    // Ensure, that ncurses will be properly exited

  defer ncurses.Endwin()

  defer func() {

    if r := recover(); r != nil {

      ncurses.Endwin()

      fmt.Printf("panic:\n%s\n", r)

      os.Exit(-1)

    }

  }()

  // Enable color mode

  ncurses.StartColor()

  // Define color pairs

  ncurses.AddColorPair("bw", ncurses.ColorGreen,ncurses.ColorBlack)

  ncurses.AddColorPair("wb",ncurses.ColorWhite, ncurses.ColorBlue)

  // Set cursor visiblity to hidden

  ncurses.SetCursor(ncurses.CURSOR_HIDDEN)

  // Automatically refresh after each command

  w.AutoRefresh = true

  // Set color for stdscr-window to system defaults.

  w.Wbkgd("std")

  // Draw a border around main window (stdscr)

  w.Box()

  // Create a new window for greeting-text at cell (x=20,y=5) with a size of 25 x 5 cells.

  w2,err := ncurses.NewWindow("dialog",ncurses.Position{20,5},ncurses.Size{25,5})

  // This can fail if the terminal is too small.

  if err != nil {

    panic(err)

  }

  w2.AutoRefresh = true

  // Use color pair wb (2)

  w2.Wbkgd("wb")

  // Draw a border around our "Greeting Window".

  w2.Box()

  // Move cursor relative to the window borders of w2

  w2.Move(2,3)

  // Output our greeting text

  fmt.Fprintf(w2, "Hello from Go\u2122-Lang!") 

  // Move cursor relative to the beginning of our main window

  w.Move(17,19)

  // Output exit instruction for the user

  fmt.Fprintf(w," => Press a key to exit <=")

  // Wait for user input (e.g. keypress)

  w.Getch()

}
