Functions related to terminals.

Latest release 20200521:

• New status() function dragged in from cs.logutils, which uses cs.upd for status() -- needs some refactoring to match with the other functions in cs.tty -- text vs bytes, stdout vs stderr, etc.
• Get warning() from cs.gimmicks.

Function setupterm(*args)

Run curses.setupterm, needed to be able to use the status line. Uses a global flag to avoid doing this twice.

Function status(msg, *args, **kwargs)

Write a message to the terminal's status line.

Parameters:

• msg: message string
• args: if not empty, the message is %-formatted with args
• file: optional keyword argument specifying the output file. Default: sys.stderr.

Hack: if there is no status line use the xterm title bar sequence :-(

Function statusline(text, fd=None, reverse=False, xpos=None, ypos=None)

Update the status line.

Function statusline_bs(text, reverse=False, xpos=None, ypos=None)

Return a byte string to update the status line.

Function ttysize(fd)

Return a (rows, columns) tuple for the specified file descriptor.

If the window size cannot be determined, None will be returned for either or both of rows and columns.

This function relies on the UNIX stty command.

Class WinSize(builtins.tuple)

WinSize(rows, columns)
