A DESCRIPTION OF THE REQUEST :
java.io.Console needs to have many methods added so that it can support the building of command line interfaces.
Here are some desperately needed methods:
1) a method to return the number of charactersc in one console line
2) a method to clear the current line of output and have the cursor left at the start (left) of the line
JUSTIFICATION :
1) is needed if you want to format stuff like tables for console output: you need to know how wide it is.
2) is needed because supplying a \r char has at least 2 defects:
a) may only work on windows and unix, but possibly not on some other OSes which treat it as a \n
b) even on those platofrms in which it works, it does not actually clear the line, but merely moves the cursor back to the start; any previous chars are left there.
And why do I need a command line interface? Because sometimes for rapid development this is the fastest way to get output and I really do not want to have to spend the time to code up a GUI.
Also, I do a lot of work running java programs on advanced remote unix servers, and I am using an ssh terminal to tap into the server, so GUIs are impossible anyways.
