Annotation of researchv9/X11/src/X.V11R1/clients/xterm/CHANGES, revision 1.1

1.1     ! root        1: VERSION X10/6.6A
        !             2: ------- -------
        !             3: 
        !             4: General
        !             5: -------
        !             6: 
        !             7: vt102 and Tektronix 4015 emulation in separate windows, each with its own
        !             8: mode menu (control middle button).
        !             9: 
        !            10: Switching between each mode can be done via the menus, or with escape
        !            11: sequences:
        !            12:        vt102 -- \E[?38h --> tek
        !            13:        tek   -- \E\003  --> vt102
        !            14: 
        !            15: The windows hilite themselves when the mouse is with either window or when
        !            16: one of these is the focus window.  The windows unhilite when the mouse moves
        !            17: out of the window and neither is the focus window.  Hiliting appears as
        !            18: windows with solid color borders and solid block cursors.  Unhiliting appears
        !            19: as windows with "grayed" borders and a rectangle cursor.
        !            20: 
        !            21: The parser for both modes is table-driven and is much more efficient than the
        !            22: original parsers.
        !            23: 
        !            24: If UTMP is define in the Makefile, then each instance of xterm makes an entry
        !            25: in /etc/utmp and thus appears with the "who" command.
        !            26: 
        !            27: If both windows are visible and one is iconified, both disappear.  Deiconifing
        !            28: causes both to appear again.
        !            29: 
        !            30: If the initial mode is vt102, /etc/termcap is searched, in order, for the
        !            31: following termcaps, until one is found:
        !            32:        xterm, vt102, vt100, ansi, dumb
        !            33: If the vt102 window happens to be 80x24, then xterms is added to the begining
        !            34: of the list.  If the initial mode is tek, the termcaps searched for are:
        !            35:        tek4015, tek4014, tek4013, tek4010, dumb
        !            36: 
        !            37: The window size is passed to the operating system via TIOCSWINSZ (4.3) or
        !            38: TIOCSSIZE (sun).  A SIGWINCH siganl is sent if the vt102 window is resized.
        !            39: 
        !            40: For login windows, menus are disabled until a user has successfully login.
        !            41: (||| This isn't currently true. )
        !            42: 
        !            43: A new menu (xterm) has been added (control left button) that gives the version
        !            44: number.  The menu allows titlebars to be displayed (see below), the windows
        !            45: redrawn, or for various signals to be sent to the process group of the command
        !            46: xterm is executing.  The signals include SIGCONT, SIGTSTP,SIGHUP, SIGINT,
        !            47: SIGTERM and SIGKILL.
        !            48: 
        !            49: Titlebars for the window can be turned off with .Xdefaults
        !            50: "xterm.TitleBar off", with command line option -tb or via the xterm menu.
        !            51: 
        !            52: The titlebar font is, by default, vtsingle.  The font can be changed with
        !            53: .Xdefaults "xterm.TitleFont helv12b" for helv12b font or via command line
        !            54: option -ft helv12b.
        !            55: 
        !            56: The titlebar look like Macintosh titlebars.  A series of strips appears when the
        !            57: window is hilited, and are gone when unhilited.
        !            58: 
        !            59: Both windows are visible and the mouse cursor is in either window, only the
        !            60: active window is hilited (before both windows were hilited).
        !            61: 
        !            62: Visual bell mode can be turned on via .Xdefaults "xterm.VisualBell on", via
        !            63: command line option -vb and from the xterm menu.
        !            64: 
        !            65: The tek window has the same name as the vt102 window, but with " (Tek)"
        !            66: appended (before they were the same).
        !            67: 
        !            68: There are several bug fixes including better sun compatibility and a problem
        !            69: in the vt102 parse table.
        !            70: 
        !            71: Xterm now always creates its own icon(s), which includes the window's name.
        !            72: The -i option now means startup showing the icon.  The option #[+-]x[+-]y
        !            73: means to position the icon there instead of centered within the window.
        !            74: The icon reverse-videos with the windows.
        !            75: 
        !            76: When the mouse is in the stripped area of the titlebar, you can get any
        !            77: of the two menus without pressing the control key.  Clicking in the
        !            78: actual title iconifies.  Clicking in an icon deiconifies it.
        !            79: 
        !            80: Many mode option on the command line allow a '+' instead of '-' to indicate
        !            81: turning off the indicated mode.
        !            82: 
        !            83: Color support has been improved, so that an unselected cursor is an empty
        !            84: rectangle with the foreground color, and the selected cursor is a filled
        !            85: rectangle with the cursor color.
        !            86: 
        !            87: A better and faster menu package has been added that supports (Mac-like)
        !            88: checkmarks and dimmed (disabled and grayed) item, as well as line separator
        !            89: items.
        !            90: 
        !            91: To conserve on resources, the unhilited border of the window(s) is now
        !            92: always a gray pixmap, which is shared by the menu package.
        !            93: 
        !            94: Logging capability has been added, in which all characters sent to the
        !            95: xterm window are recorded.  The mode is turned on by using .Xdefaults option
        !            96: "xterm.Logging on", -l on the command line, from the xterm menu or the
        !            97: escape sequence \E[?46h in vt102 mode.  Logging is turned off through the
        !            98: xterm menu or \E[?46l in vt102 mode.  The default log file is XtermLog.XXXXX
        !            99: (XXXXX is the process id of xterm) and is in the initial directory in which
        !           100: xterm was started (the home directory for login xterms).  Each logging start
        !           101: appends to the end of the loggin file, and each logging stop closes the file.
        !           102: 
        !           103: An alternate logging file may be given with .Xdefaults "xterm.LogFile file"
        !           104: (file is the alternate filename) or with command line option "-lf file".
        !           105: If the first character of the logfile name is `|', then the rest of the
        !           106: name passed to the shell for execution and a pipe is created to the process.
        !           107: In this case, each time the log is started, a new process is created and
        !           108: when logging is turned off, the pipe is closed.  Thus, a logfile name of
        !           109: "| lpr", will send text to the line printer each time logging is turned off.
        !           110: 
        !           111: Certain modes may be inhibited by specifying in the .Xdefaults file.  A
        !           112: change to the initial logging mode may be prevented with "xterm.LogInhibit on",
        !           113: which will prevent changes to logging from the menu or from escape sequences.
        !           114: "xterm.SignalInhibit on" disables the xterm menu signal sending (Continue is
        !           115: still allowed).  "xterm.TekInhibit on" prevents entering into Tektronix mode.
        !           116: 
        !           117: As per edjames@eros, xterm sets the environment variable WINDOWID, which
        !           118: contains the Window id of the initial window (normally vt102, but could be
        !           119: the tek window if the -t option were specified).  This "feature" is
        !           120: bogus, as it may not always give you all information you need to
        !           121: access a window.
        !           122: 
        !           123: The title in the title bar may be changed with the \E]0;new title\007 escape
        !           124: sequence.  Any non-printing character terminates the title string.  The
        !           125: windows and icons are also renamed, and the icons are resized to fit the
        !           126: new title.
        !           127: 
        !           128: The log file may be changed with the \E]46;new log file\007 escape sequence.
        !           129: If the log file name is empty, the default log file name is used.
        !           130: 
        !           131: In visual bell mode, the icons now flash on receipt of a control-G.
        !           132: 
        !           133: If xterm is iconified and new input comes in, a box is drawn around the
        !           134: icon title.
        !           135: 
        !           136: The bitmap used for the icons is now user definable.  The VT102 bitmap may be
        !           137: set with .Xdefaults "xterm.IconBitmap file" or with "-ib file" on the command
        !           138: line.  The Tek bitmap may be set with .Xdefaults "xterm.TekIconBitmap file"
        !           139: or with "-it file" on the command line.  These files are assumed to be
        !           140: bitmap(1) format files.
        !           141: 
        !           142: Normally, the title text of the icon is displayed to the right of the
        !           143: bitmap.  The text may be displayed under the bitmap by using .Xdefaults
        !           144: "xterm.TextUnderIcon on" or with -ti on the command line.
        !           145: 
        !           146: The mouse may be automatically warpped to the xterm window when it is
        !           147: deiconified by using .Xdefaults "xterm.DeiconifyWarp on" or using -dw on
        !           148: the command line.  This is also of questionable merit.
        !           149: 
        !           150: The standard error output used by xterm is now improved.  Normally it will
        !           151: be the same standard error when xterm is started.  For login xterms
        !           152: (-L specified) then the standard error will be to /dev/console.
        !           153: 
        !           154: X error events are now intercepted so that xterm may cleanup before exiting
        !           155: (like resetting the tty modes and clearing the /etc/utmp entry).
        !           156: 
        !           157: VT102
        !           158: -----
        !           159: 
        !           160: vt102 emulation is much more complete than the original xterm.
        !           161: 
        !           162: Underlined characters is now supported.
        !           163: 
        !           164: The text for selection and extension is now hilited by reverse video.
        !           165: 
        !           166: Pasting text that was originally displayed as vt102 graphic characters now
        !           167: returns the original ascii character (and not the internal representation).
        !           168: 
        !           169: Text that is scrolled off the top of the window can be saved and is accessable
        !           170: via a scrollbar.  The scrollbar is normally off, but may be made visible with
        !           171: .Xdefault option "xterm.ScrollBar on" or command line option -sb.  The
        !           172: scrollbar state can be changed via the mode menu.
        !           173: 
        !           174: The default maximum number of lines saved off the top is 64, but can be
        !           175: specified in .Xdefaults as "xterm.SaveLines 100" for 100 lines, or as
        !           176: a command line option "-sl 100".
        !           177: 
        !           178: A margin bell can be turned on via .Xdefaults "xterm.MarginBell on", command
        !           179: line option -mb or mode menu.  The default number of columns from the right
        !           180: margin is 10 and is settable via .Xdefaults "xterm.NMarginBell 15" for 15
        !           181: columns, or via command line option -nb 15.  The mode may be changed by escape
        !           182: sequence \E[?44h (on) and \E[?44l (off).
        !           183: 
        !           184: To emulate the vt102 switching between 80 and 132 columns, the mode may
        !           185: be turned on via .Xdefaults "xterm.C132 on", via command line option -132 or
        !           186: via the mode menu.  The mode may be changed by escape sequence \E[?40h (on)
        !           187: and \E[?40l (off).
        !           188: 
        !           189: A mode that fixes a bug in curses (e.g. when using "more" on lines that have
        !           190: lines that print on the last column of the line and the next line begins with
        !           191: a tab) can be turned on .Xdefaults "xterm.Curses on", command line option
        !           192: -cu or via the mode menu.  The mode may be changed by escape sequence
        !           193: \E[?41h (on) and \E[?41l (off).
        !           194: 
        !           195: Auto linefeed mode and auto repeat are supported.
        !           196: 
        !           197: The mode menu is now more descriptive.
        !           198: 
        !           199: Most Dec Private mode settings can be save away internally using \E[?ns,
        !           200: where n is the same number to set or reset the Dec Private mode.  The
        !           201: mode can be restored using \E[?nr.  This can be used in termcap for vi, for
        !           202: example, to turn off saving of lines, but restore whatever the original
        !           203: state was on exit.
        !           204: 
        !           205: An optional status line (in reverse video) has been added to the bottom of
        !           206: the vt102 window.  The following escape sequences work on the status line:
        !           207:        \E[?S           show status line
        !           208:        \E[?H           hide status line
        !           209:        \E[?nT          enter status line, at column n
        !           210:        \E[?F           return to the position before entry into status line
        !           211:        \E[?E           erase status line

        !           217: \E[?45h turns on reverse wraparound and \E[?45l turns it off.  Reverse
        !           218: wraparound only works when autowrap is also on and is useful, for instance,

        !           260: All of the tek character sequences are stored and can be saved into a file
        !           261: via the standard COPY escape sequence or from the mode menu.  The file created
        !           262: is named COPYyy-mm-dd.hh:mm:ss (COPY plus the date and time) and is placed
        !           263: in the initial directory in which xterm was started.  Login xterms use the

        !           272: the cross cursor, similar to standard Tek GIN mode.  Pressing a mouse button
        !           273: instead will send the character `l', `m' or `r' depending on whether the
        !           274: left, middle or right button was pressed, respectively.  If the shift key was
        !           275: down when the button was pressed, the corresponding upper case character is
        !           276: sent.  To distinquish a button press from a key press, the high bit of the
        !           277: character is set, but this is only useful if the tty mode is set to RAW to
