in my go-application which is cli-based I Need to update some values which are already printed. I already found a stackoverflow-question where I got to know that with the "Output-pointer" points to the first char of the former line, therefore overriding it. But multiple s arent working... So how do I update e.g. the second line I printed. Example:
#Id #Name #pwr #dB
0 Name unkn -34
And I want to update those values without printing new lines
#Id #Name #pwr #dB
0 NewName 45 -34
To do anything more than changing the current line, as you noticed, won't work. The solution is to set your terminal in a different mode which allow more control. However, this is painful to do by hand. Luckily, there are libraries out there that makes it easy. A very famous one is ncurses.
For Go, GoCUI looks great. It should give you all the power you need with a nice interface.
