http://austingroupbugs.net/bug_view_page.php?bug_id=1063

We have started on this item and need to continue at a future meeting.

Bug 1151: Introduce new signal SIGWINCH and functions tcsetsize(), tcgetsize() to get/set terminal window size  Accepted as Marked
http://austingroupbugs.net/view.php?id=1151 

This item had been reopened on the list. The resolution has been updated
to rename the functions to  tcgetwinsize() and tcsetwinsize().

Bug 1053: Add a "size" mode to stty(1)         Accepted as Marked
http://austingroupbugs.net/view.php?id=1053

After applying the changes from Bug 1151, make the following changes:

On page 3264 lines 109758-109761 (XCU stty -g) change:
    -g

	Write to standard output all the current settings in an
	unspecified form that can be used as arguments to another
	invocation of the stty utility on the same system. The form
	used shall not contain any characters that would require
	quoting to avoid word expansion by the shell; see Section
	2.6 (on page 2353).
to:
    -g

	Write to standard output all the current settings, optionally
	excluding the terminal window size, in an unspecified form
	that, when used as arguments to another invocation of the
	stty utility on the same system, attempts to apply those
	settings to the terminal. The form used shall not contain
	any sequence that would form an Informational Query, nor
	any characters that would require quoting to avoid word
	expansions, other than field splitting, by the shell; see
	Section 2.6 (on page 2353).


On page 3264 line 109763 (XCU stty operands) change:
    The following operands shall be supported to set the terminal
    characteristics.
to:
    The following operands shall be supported.

On page 3269 after line 109976 (XCU stty operands) insert two new operands subsections:
    Terminal Window Size

    rows number
        Set the number of rows in the terminal window size to the number given.


    cols number
	Set the number of columns in the terminal window size to
	the number given.


    The terminal window size shall be updated as if the stty utility
    calls tcgetwinsize() to populate a winsize structure, updates
    one or both of the ws_row and ws_col members according to the
    rows and cols numbers specified, and then calls tcsetwinsize()
    with the updated structure (see [xref to XSH tcgetwinsize] and
    [xref to XSH tcsetwinsize]).

    Informational Queries

    size
        Write the current terminal window size to standard output.


On page 3270 line 109999 (XCU stty STDOUT) change:
    If operands are specified, no output shall be produced.

to:
    If operands are specified and they do not include any Informational
    Queries, no output shall be produced.

    If the size operand is specified, stty shall write to standard
    output the terminal window size as follows:

    <tt>"%1d^%1d\n", <rows>, <columns></tt>

(note to readers of the minutes: ^ is delta space symbol)

    where <tt><rows></tt> and <tt><columns></tt> are the number of
    rows and columns in the terminal window size, respectively.


On page 3271 lines 110036-110039 change the example to read:
saveterm=$(stty −g)                              # save terminal state
ttysize=$(printf "rows %d cols %d" $(stty size)) # save terminal size
stty new settings                                # set new state
...
stty $saveterm                                   # restore terminal state
stty $ttysize                                    # restore terminal size
