.SH DESCRIPTION
.B xtermcontrol
makes it easy to change colors, title, font and geometry of a running XFree86 
\fBxterm(1)\fR, as well as to report the current settings of the aforementioned
properties.

Window manipulations de\-/iconify, raise/lower, maximize/restore and reset
are also supported.

To complete the feature set; xtermcontrol lets advanced users issue any xterm control
sequence of their choosing.

.SH OPTIONS
.IP "\fB\-\-fg\fR=\fICOLOR\fR"
Set foreground color (see also \fBCOLOR NAMES\fR).
.IP "\fB\-\-bg\fR=\fICOLOR\fR"
Set background color.
.IP "\fB\-\-color\fIN\fR=\fICOLOR\fR"
Set N'th [0-255] color to COLOR, e.g. \-\-color88=COLOR.
.IP "\fB\-\-highlight\fR=\fICOLOR\fR"
Set highlight color.
.IP "\fB\-\-cursor\fR=\fICOLOR\fR"
Set cursor color.
.IP "\fB\-\-mouse\-fg\fR=\fICOLOR\fR"
Set mouse pointer foreground color.
.IP "\fB\-\-mouse\-bg\fR=\fICOLOR\fR"
Set mouse pointer background color.
.IP "\fB\-\-font\fR=\fIFONT\fR"
Set font name (see also \fBFONT NAMES\fR). Alternatively it is possible to specify
a fontmenu index as \'#[0-6]\' or navigate the fontmenu by
relative sizes as \'#+N\' or \'#\-N\', where N is an optional integer.
.IP "\fB\-\-title\fR=\fISTRING\fR"
Set window title. Note that mechanisms like the \fBbash(1)\fR
PROMPT_COMMAND may overwrite the title.
.IP "\fB\-\-geometry\fR=\fIWIDTHxHEIGHT+XOFF+YOFF\fR"
Set size and/or position. Through its control sequences the xterm only
recognize positive \fIXOFF\fR and \fIYOFF\fR offsets, which are pixels relative to the
upper left hand corner of the display. xtermcontrol is therefore unable to
handle negative offsets as described in the \fBX(7x)\fR GEOMETRY SPECIFICATIONS
and therefore truncates negative values to zero.
.IP "\fB\-\-get\-fg\fR"
Report foreground color.
.IP "\fB\-\-get\-bg\fR"
Report background color.
.IP "\fB\-\-get\-color\fIN\fR"
Report N'th [0\-255] color, e.g. \-\-get\-color88.
.IP "\fB\-\-get\-highlight\fR"
Report highlight color.
.IP "\fB\-\-get\-cursor\fR"
Report cursor color.
.IP "\fB\-\-get\-mouse\-fg\fR"
Report mouse pointer foreground color.
.IP "\fB\-\-get\-mouse\-bg\fR"
Report mouse pointer background color.
.IP "\fB\-\-get\-font\fR"
Report font.
.IP "\fB\-\-get\-title\fR"
Report window title.
.IP "\fB\-\-get\-geometry\fR"
Report size and position. The size of the text area is reported in characters and
the position is reported in pixels relative to the upper left hand corner of the display.
.IP "\fB\-\-maximize\fR"
Maximize window.
.IP "\fB\-\-restore\fR"
Restore maximized window.
.IP "\fB\-\-iconify\fR"

.IP "\fB\-\-force\fR, \fB\-f\fR"

.\"   "CONFIGURATION"
.\"
.SH CONFIGURATION
The default configuration file ~/.xtermcontrol is sourced if xtermcontrol is run without options or if specifically requested, e.g. 'xtermcontrol \-\-file=~/.xtermcontrol'. 

Each line in a configuration file is either a comment or contains an attribute.
Attributes consist of a keyword and an associated value:
.nf
.sp
      keyword = value # comment
.sp
.fi
The valid keyword/value combinations are:
.nf
.sp
      foreground="COLOR"
      background="COLOR"
      highlight="COLOR"
      cursor="COLOR"
      mouse\-foreground="COLOR"
      mouse\-background="COLOR"
      geometry="WIDTHxHEIGHT+XOFF+YOFF"
      font="FONT"
      color0="COLOR"
      color1="COLOR"
      color2="COLOR"
      color3="COLOR"
      color4="COLOR"
      color5="COLOR"
      color6="COLOR"
      color7="COLOR"
      color8="COLOR"
      color9="COLOR"
      color10="COLOR"
      color11="COLOR"
      color12="COLOR"
      color13="COLOR"
      color14="COLOR"
      color15="COLOR"
.sp
.fi
Whitespace is ignored in attributes unless within a quoted value. The
character \'#\' is taken to begin a comment. Each \'#\'
and all remaining characters on that line is ignored.
.\"
.\"   "FONT NAMES"
.\"
.SH FONT NAMES
xtermcontrol accepts any \fBX(7x)\fR FONT NAMES.
Font names like \'\-adobe\-courier\-medium\-r\-normal\-\-10\-100\-75\-75\-m\-60\-iso8859\-1\' are
very cumbersome to write, so it is convenient to make use of aliases, e.g.
\'fixed\' or \'8x13\', if present in fonts.alias files of the font directories.
.\"
.\"   "COLOR NAMES"
.\"
.SH COLOR NAMES
xtermcontrol accepts any \fBX(7x)\fR COLOR NAMES.
Basically this means that colors are specified by name or rgb value, e.g. \'blue\',
\'rgb:0000/0000/FFFF\' or \'#00F\'. Colors are typically reported by the
xterm in a device-dependent numerical form, e.g. \'rgb:0000/0000/FFFF\'.
Note that old syntax rgb values should always be quoted to avoid \'#\' being
interpreted as the beginning of a comment by the shell (see also \fBFILES\fR).
.\"
.\"   "XTERM CONTROL SEQUENCES"
.\"
.SH XTERM CONTROL SEQUENCES
The secret behind xtermcontrol is xterm control sequences. All the possible
(there are a plethora of them) control sequences are documented in ctlseqs.txt,
found in the \fBxterm(1)\fR distribution (see also \fBFILES\fR).

.\"   "XTERM CONTROL SEQUENCES"
.\"
.SH MACOS TERMINAL.APP
The macOS Terminal.app emulates an extended set of the VTxxx series commands, closely resembling dtterm.
Therefore the following subset of xtermcontrol options works as expected:
.nf
.sp
      \-\-title
      \-\-geometry
      \-\-get\-geometry
      \-\-maximize
      \-\-restore
      \-\-iconify
      \-\-de\-iconify
      \-\-raise
      \-\-lower
      \-\-reset
.sp
.fi
Color names are ignored, but device-dependent numerical form and rgb values works as expected for
the following subset of xtermcontrol options (see also \fBCOLOR NAMES\fR):
.nf
.sp
      \-\-fg
      \-\-get\-fg
      \-\-bg
      \-\-get\-bg
      \-\-cursor
      \-\-get\-cursor
      \-\-mouse-fg
      \-\-get\-mouse-fg
      \-\-mouse-bg
      \-\-get\-mouse-bg
.sp
.fi

.\"   "BUGS"
.\"
.SH TROUBLESHOOTING
If read/write permissions on the tty's are changed so
that special group membership is required to be able to write to the pseudo terminal,
the easiest workaround is to install xtermcontrol setuid root.

\fBXterm(1)\fR has three resources, allowWindowOps, allowTitleOps, and
allowFontOps, that enables or disables special operations which xtermcontrol relies on.
If any of these resources are set (or defaults) to 'false' xtermcontrol may hang.
The resources corresponds to xtermcontrol options as:
.nf
.sp
   allowWindowOps:
      \-\-raise
      \-\-lower
      \-\-restore
      \-\-maximize
      \-\-iconify
      \-\-de\-iconify
      \-\-get\-title
      \-\-geometry
      \-\-get\-geometry

   allowTitleOps:
      \-\-title

   allowFontOps:
      \-\-font
      \-\-get\-font
.sp
.fi
All three resources can usually be enabled for the current xterm session via a menu; ctrl+rightclick and look for menu item names like 'Allow Window Ops'. To set these resource values persistently you can add the following to either your local ~/.Xdefaults file, or to a system-wide resource file like /etc/X11/app\-defaults/XTerm:
.nf
.sp
   *VT100.allowWindowOps: true
   *VT100.allowTitleOps: true
   *VT100.allowFontOps: true
.sp
.fi
