Windows terminal size #12

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Hi,

The library uses the wrong terminal width on windows so here is some code for 
finding it:

def get_windows_term_width():
    from ctypes import windll, create_string_buffer
    h = windll.kernel32.GetStdHandle(-12)
    csbi = create_string_buffer(22)
    res = windll.kernel32.GetConsoleScreenBufferInfo(h, csbi)
    if res:
        import struct
        (bufx, bufy, curx, cury, wattr,
         left, top, right, bottom, maxx, maxy) = struct.unpack("hhhhHhhhhhh", csbi.raw)
        sizex = right - left + 1
    else:
        sizex = 80
    return sizex

Your library really rocks btw!

Cool. I didn't even know that windows terminals could be resized horizontally. 
Does that work for all windows versions?

Both of you are cool. FYI get_windows_term_width's working report is following.
Every test runs on Windows XP SP3 x86.

IronPython doesn't allow such syntax of new line.
