Here is
the latest version of this file.
It began as a list of the changes that I made for xterm, using
the notes that I added when submitting a patch. You should note
that other changes were made as well, by other people, to fix
bugs and correct ifdef's for portability. Until mid-2006, most of
these were summarized in the XFree86
CHANGELOG).
- modify DECFRA and DECRQCRA to handle NRCS
and ISO character set mappings.
- ensure that the cursor GC is updated when switching between
normal and italic fonts (report/testcase by Peter
Fabinski).
- reduce overflow in scaling of ReGIS coordinates
(report/testcase by Robert L Masterson).
- improve permissions-check for valid shell program.
- extend modifyOtherKeys and
formatOtherKeys to the various categories of special
keys, i.e., cursor-keys, function-keys, keypad-keys,
modifier-keys and (other) special-keys.
- review/extend convmap.pl to handle all of the
X11 keysym definitions in keysym2ucs.
- keysyms which do not correspond to Unicode character
codes are mapped to Unicode private use areas in the BMP
and plane 15.
- add/extend control sequences for the new format- and
modify-resources.
- fix copy/paste error in configure script for default value
of --enable-block-select (report by Vincent
Lefèvre).
- revise keysym2ucs.c, to provide mapping to/from
the Unicode private use area for non-character keysyms. Also
remove redundant items from keysym.map.
- improve modifyOtherKeys, by providing the UCS
value for keys which have no single-byte representation (Debian
#1093056).
- add two extensions to modifyOtherKeys:
- setting modifyOtherKeys to 3 makes all
keyboard input send escape sequences, using parameter 1
where no modifiers are given.
- a subparameter can be added to the XTMODKEYS
control sequence, telling xterm to factor-out the
corresponding modifier mask from available parameters in
the modifyOtherKeys feature.

disallowWindowOps, for DECCOLM,
DECANM and DECSASD, DECSSDT
respectively (report by Sami Farin).

applications to send a client message which can modify the
default foreground and background colors (adapted from patch by
Claes Nästén).

XTGETTCAP (prompted by discussion with David Leadbeater).
- improve limit-checks for fallback font cache (report by
Dimitrije Erdeljan).
- improve check for too-wide glyph in fallback font by
allowing xterm to continue searching for a suitable font rather
than just failing on the first. Also add
limitFontWidth to allow changing the amount by which a
glyph must extend outside the font's bounding box to disallow
it.

OPT_COLOR_RES and
OPT_COLOR_RES2.
- improve performance over slow connections (report by Harald
Dunkel).
- update cursor if restoring mode for DECTCEM.

CharWidth macro to ensure that the
shortcut for Latin-1 is only applied when UTF-8 is not enabled,
to fix a bug in handling soft-hyphen from patch #334 changes (patch by Martijn van
Duren).
- improve terminfo:
- fill-in function-keys in terminfo which are not Sun/HP
keyboards using
xterm+nopcfkeys
building-block.
- add kbeg to xterm+keypad to accommodate termcap
applications
- add smglp and smgrp to vt420+lrmm, to provide useful
data for the "tabs"
+m
option
- support shift-tab in Sun, HP and SCO keyboards.
- document some legacy features in
ctlseqs.ms
(prompted by discussion with Jimmy Aguilar Mena "Ergus").
- add “trim” option to
cdXtraScroll
and tiXtraScroll.
- remove support for non-fifo save-lines configuration.
- extend
cdXtraScroll to check if the cursor is
at the upper-left of the scrolling region when the erasure is
for the remainder of the screen versus the whole screen
(prompted by discussion with Jörg Breitbart).
- add workaround for broken pcre2 package in Debian 10.
- change screen-refresh call used for
DECCARA
and DECRARA to ensure that trailing blanks which
are part of the rectangle are repainted (report/analysis by
Dennis Filder).
- when resetting the terminal, ensure that the cursor shape
also is reset, e.g., if
DECSCUSR has been used to
modify the cursor shape for an xterm which was started with the
underlined cursor option (report/analysis by Luis Javier
Merino).
- prevent
DECSCUSR from blinking the cursor if
the cursorBlink resource is “never”
(report by Vladimir D Seleznev).
- invert the sense of
DECSDM, to correspond with

- update tables in
wcwidth.c based on Unicode
14.0.0
- add
DefaultOff option to
RenderFont resource, as part of the
session-management feature.
- add auto-scroll-lock feature (patch by Stelios
Bounanos).
- update the window-size information returned via
TIOCGWINSZ when rows/columns are unchanged but the
font-size changes (report by Nick Black).
- improve session-management feature by saving/restoring the
font settings.
- update config.guess, config.sub
- add
OSC 22 to allow programs to select
different pointer cursor at runtime.
- change configuration for no-return functions to
use
_Noreturn when it is available, because
clang --analyze does not properly handle the gcc
noreturn attribute.
- add
cursorTheme resource to provide a way to
enable or disable the cursor theme feature.
- modified
CopyWait event retries to use shorter
sleeps, to improve responsiveness (tmux #2556).
- improve quoting/escaping in demo-scripts per
shellcheck.

coordinate values (report by "CismonX").
- correct upper-limit for selection buffer, accounting for
combining characters (report/testcase by Tavis Ormandy).
- with
alwaysHighlight true, xterm does not
properly track focus. The screen->select
FOCUS flag remains always on, which prevents
bellIsUrgent from working, as the urgent
WM_HINT flag is only set in
setXUrgency() when the window is not focused. Fix
this by updating screen->select in
unselectwindow() regardless of the value of
always_highlight (patch by Jiri Bohac).
- improve fix for interaction between SRM and ENQ (report by
Grant Taylor).
- build-fix for
--with-Xaw3dxft, needed when
--with-toolbar is omitted (report by Jimmy Olgeni,
Emanuel Haupt).
- amend fix for “word” selection in patch #364 to limit that to the
insert-selectable action, which reads
data from the screen. This restores the interactive behavior
where double-clicking on a “word” would make
subsequent selection extensions by words as well as suppressing
some boundary-checks (report by David Wolfskill, FreeBSD
#253225).
- add
-fc option.
- correct/improve limit-checks for SRM versus ENQ from
patch #344 (report by Tom
Szilagyi).

&4” Cyrillic to
non-NRCS, per VT520 manual.
- amend fix for SCS in patch #198 to
remove
DEL rather than converting it to a space
(report by Thomas Wolff).
- modify state transitions for selecting character sets to
eliminate an ambiguity between the “A” used in
VT220 versus VT320.
- improve error recovery when selecting characters by
resetting to US ASCII when no suitable encoding is found, e.g.,
attempting to use an NRCS sequence when NRCS is not
enabled.
- turn off hyphenation in “
.txt”
conversion, prompted by groff changes.

event-handling in
CopyWait to handle active-icon
as a special case (Debian #975687).
- add call to
loadColorTable to get the visual
information needed to decode BE RGBA32 color format (patch by
Leandro Lupori).
- modify the resource-parsing for
disallowedPasteControls and similar lists of
names/numbers to recognize “~;” (tilde) for
cancelling a given name/number.
- add ENQ, EOT and NUL to default for
disallowedPasteControls.
- change default for
disallowedPasteControls to
omit the tab character (suggested by Harald Dunkel).
- fix swapped height/width in
regisScreenSize
and maxGraphicSize resources using "auto" value,
from patch #314 (report by Anton
Lavrentiev)
- revise patch #362 change for
shift-modifier versus mouse protocol and select/paste by adding
resource
shiftEscape, which can be enabled via a
control sequence (prompted by discussion with Matthijs van
Duin).
- simplify/improve ifdef in trace code for using a separate
set of files for each run of xterm.
- add options
-r and -t to
vttests/query-color.pl to show the 6-digit RGB
code and actual colors.
- add
nel to xterm-basic
terminfo.
- alter
vttests/modify-keys.pl to omit HTML
reference links to the modified-keys table where no keycode was
available.
- cleanup of calls to
free, removing checks for
null (Walter Harms).
- improved mouse-button reporting (prompted by discussion
with Stephane Chazelas)
- narrow the scope of the change for shift-key in
patch #361 to make it apply only
when the
modifyOtherKeys resource is set to 2
(i.e., “program mode”). Also, when checking the
shift-key, ignore modifiers other than shift, control and
“meta”
- use the alt/meta modifier information obtained in
VTInitModifiers to replace a hard-coded
mod1 used to detect “Meta” for
mouse-button responses.
- reduce
SIGWINCH's sent to the client by
filtering out duplicates.
- improve display when
scaleHeight is greater
than 1:
- the text-cursor is vertically-centered on the current
line, rather than only extending below the current line
(report by Manu Chaturvedi).
- the built-in line-drawing characters extend to the
scaled cell-height.
- fill-in special case for motion-events to match the changes
for shift-key in pointer-button events from patch #361.
- treat the return value of
strerror as readonly
(patch by Philipp Klaus Krause).
- modify event-handling in
CopyWait to work
around hanging while writing large amounts of text to an active
icon and at the same time iconifying/deiconifying (report by
Dave Kemper).

- improve manual page description of scrollbar resources
(report by Brian Lindholm).
- correct ifdef for menu entry for active-icon, when
initializing it with toolbar configuration.
- add preprocessor option to makefile to set internal
definition of pixmaps directory to match the
install-configuration (FreeBSD #250036).
- cleanup of calls to
free, removing checks for
null (Walter Harms).
- add fallback actions
pointer-button and
pointer-motion which handle events for the mouse
control-sequences protocol if the select-related
translations are omitted with
*omitTranslation:select (prompted by discussion
with "Ergus")
- amend rule for using shift-key to override mouse-protocol
for select/paste to limit that feature to mouse-buttons which
are actually bound to select/paste actions (prompted by
discussion with "Ergus").
- corrected mapping in special case for repainting wrap-marks
when viewing the scrollback area.
- use separate GCs for
showWrapMarks
feature, to work around cursor coloring change in patch #345 (report by Paulo Silva de
Alíbano).
- mention
decGraphicsID in
ctlseqs.ms (suggested by Thomas Wolff).

changes where only the first selection buffer specified in the
request would be updated using OSC 52 (patch by Michael

this (prompted by discussion with Thomas Wolff).
- add control sequences for fast switching of color palettes:
XTPUSHCOLORS, XTPOPCOLORS,
XTREPORTCOLORS
- amend change for soft-hyphen from patch #328 to avoid stripping
replacement-characters which would be shown with malformed or
overlong UTF-8 input.

Harms).
- fix some errata in
ctlseqs.ms (report by
Thomas Wolff).

- modify
SGR parameter handling to stop if an
unrecognized parameter is encountered, to guard against
malformed or nonstandard sequences (report by Bram
Moolenaar).
- modify
DECERA color for consistency with other
erasures/clearing (report by Thomas Wolff).
ECH should not be masked by
DECSCA (report by Thomas Wolff).- extend
DECFRA and REP to accept
any “graphic” character rather than just Latin1,
etc. (report by Thomas Wolff).
- add
-C option to 256colors2.pl and
88colors2.pl, to demonstrate mixed semicolon/colon separators
which are implied by ECMA-48.
- update sample terminfo to reflect the documentation
improvements.
- update description of 88/256/direct color in
ctlseqs.ms to point out that using semicolons is a
deprecated legacy feature, and standard terminal applications
should use colons (prompted by discussion with Bram
Moolenaar).
- modify configure-check for
tgetent to
conditionally include termcap.h, enabling
configuration using clang's pedantic-errors option
(report by Dennis Clarke). See
Other Compatibility in ncurses'
curs_termcap(3X).
- remove some unnecessary pointer checks (patch by Walter
Harms).
- accept terminal-id and add DA response for VT131,
VT132.

resources, so that
scaleHeight and
faceSize settings do not depend on locale (Debian
#820803).
- improve DA/DA2 response by ensuring that the
decTerminalID maps to one of the known
identifiers, as well as providing DA2 response for VT241 and
VT382.
- terminfo improvements:
- add (my) comments from ncurses which explain the keypad
layouts.
- add
vt52+keypad from ncurses
- use improved
xm example for
xterm+x11mouse, xterm+sm+1006
from ncurses 6.2 terminfo.src

test-drivers for charclass and wcwidth data.
- quiet “did not find a usable xxx TrueType
font” warnings by making
fontWarnings apply
to these messages (report by Jim Rees).
- improve reinitialization of parameter list (report/testcase
by James Holderness).
- temporarily set numeric locale category to "C" when
formatting SVG or XHTML screendumps, to make the radix
separator used in RGB values consistent (adapted from patch by
George Kouryachy).
- add resource
forceXftHeight to control whether

uxterm to make it possible to select
nonstandard locale C.UTF-8, e.g, if the user's locale
is set to “C” (Debian #940626).
- re-save/tweak “.svg” icon-files to work around
breakage in toolset since the files were created in patch #283.
- amend change in patch #352 for
button-events to fix a case where some followup events were not
processed soon enough (report/patch by Jimmy Aguilar
Mena).
- handle MappingNotify X event, to improve recovery
when switching keyboard configurations using

the X libraries.
- improve discussion of mouse-mode in
ctlseqs.ms
(suggested by Igor van den Hoven).
- further improve checks for Xft max-advance-width
to take into account fonts which use two cells for ambiguous

(reports by Yuri Pankov, Frank Mosch).
- fix a few spelling errors reported by codespell (report by
Jens Schleusener).
- modify
run-tic.sh to prefer development
version of ncurses since changes to terminfo file in patch #345 rely upon bug-fixes in ncurses
(prompted by discussion with Will Senn).
- adjust fontsize data to handle a minor inconsistency from
recent Xft versions (Debian #880407, adapted from patch by
Vincent Lefèvre).
- add a table to the manual page description of
forceBoxChars to alert the reader to the special
characters aside from “line-drawing” which are
drawn directly when this resource is set (Debian #931305).
- improve
checkXft logic which attempts to
detect fonts whose max-advance-width is inconsistent
with the actual glyph widths. For some fonts, it is necessary
to check additional characters (report/analysis by Jan
Engelhardt).
- improve configure-checks for X headers and libraries on
recent MacOS, which has moved those files under
/usr/X11.
- improve portability of iconify/deiconify feature by taking
into account some window managers which manipulate the EWMH
_NET_WM_STATE property, adding/removing
_NET_WM_STATE_HIDDEN rather than actually
minimizing the window (prompted by discussion with
Jörg Breitbart).
- improve workaround from patch #287
for the
-iconic option when configured with
toolbar by postponing the extra request for minimizing the
window to the end of menu-initialization.
- modify
xevents special-case for mouse-events
to include button-events so that the meta key by itself can
generate button-events (report/analysis by Mattias
Engdegård).
- amend SGR-stack change from patch
#348 to not associate bold attribute with background color
(report by Nicholas Marriott).

esctest.
- updated autoconf macros
- update config.guess
- correct logic in
property_to_string for
deciding when to fallback from UTF-8 decoding to ISO-8859-1
decoding, broken in xterm #350
(FreeBSD #241961).
- add
-report-icons to help-message.
- improved autoconf macros:
CF_ADD_LIBS: the change to filter out
duplicates caused this to append rather than prepend.
revise to fix that.CF_GCC_VERSION and
CF_GCC_WARNINGS: move checks to distinguish
icc/clang from gcc from the macro which handles the
--enable-warnings option, to make this work
without-warnings for the inline-checks.
- update config.guess, config.sub
- correct status in
XTGETXRES replies when the
resource was not found.
- fix some gcc, cppcheck, clang and coverity warnings.
- guard call to
RequestResize from the
struct-notify event handler to prevent recursion in the
Xft+buffered workaround in some cases when doing manual
resizing rather than resizing via escape sequences (reports by
Stefan Assmann, Mike Thornburg).
- amend the workaround for Xft+buffered blanking by moving
the switch to bitmap-fonts to account for differences in font
metrics between bitmap- and TrueType-fonts (report by Stefan
Assmann).
- improve the note on the
xterm-rep terminfo
entry (prompted by discussion with Sven Joachim).
- modify html/svg dump to not ignore zero'd/blank cells.
- align terminfo file with ncurses, e.g., add
xterm+osc104 block.
- improve discussion of
modifyOtherKeys in
manual page and in ctlseqs.ms.
- add
vttests/modify-keys.pl script to
illustrate the modifyOtherKeys resource (prompted
by discussion with Bram Moolenaar).
- various improvements to
ctlseqs.ms, as part of
autogenerating links for the website.
- update manual page default for
saveLines
resource default value (Branden Robinson, Debian #913815).
- add command-line option
-report-xres to show
the values of the VT100 widget X resources when initialization
is complete.
- add a control sequence which, like tcap-query, allows an
application to inspect most X resource settings of the VT100
widget.
- adjust some optional features to enable them in the imake
configuration as they would be by default via the configure
script.
- add null-pointer checks to improve error recovery when
bitmap fonts are missing or corrupt (report by Jonne
Ransijn).
- correct the condition for deleting the EWMH window-title
property, i.e., if UTF-8 titles are disabled, rather than if an
update to the EWHM property found no change (report by Sven
Joachim).
- build-fix for the case when configure
--enable-trace is used without
--enable-warnings (report by Sven Joachim).
- fix a few minor bugs found with Coverity.
- add a check in
property_to_string to avoid
translating UTF8_STRING or
COMPOUND_TEXT into Latin-1 when UTF-8 encoding is
active, e.g., when pushing onto the title-stack while switching
to the alternate screen.
- build-fix for the
--disable-doublechars
configure option (report by Brian Lindholm).
- add graphic context to support bold+italics (patch by Quinn
Strahl).
- document window properties in the manual page.
- improve title-string feature:
- if any of
allowC1Printable,
utf8Title or titleModes hint that
an application might send a title-string encoded in UTF-8,
check if that is the case, and if it is recodable into
ISO-8859-1, use that for the ICCCM-style title.
- check if the title given by a control sequence happens
to be already encoded in UTF-8, to avoid double-encoding
(FreeBSD #240393).
- Make
sameName resource work for the EWMH
titles.
- Modify menu-state of
utf8Title to be
consistent with the utf8 source, i.e., setting
the EWMH properties automatically when UTF-8 is
active.
- reorganize text-drawing to make it
possible to investigate using Xft to implement VT100-style
double-sized characters. While doing this, made a workaround
for apparent Xft bug which loses its drawable state when
switching from 132 to 80 columns.
- improve font-warning messages by showing which are
derived rather than directly from resource settings
(suggested by Tomas Korbar). Also filter repeated font-warning
messages, to accommodate broken X configurations.
- fix an inconsistency between failure to load derived wide
font versus failure to load derived wide-bold font (Redhat
#1679790). That relies upon the “:unscaled”
property which is broken in some distributions (however, recent
Debian and the BSDs such as MacOS work).
- updated autoconf-252 to check X11R7 include/lib directories
found on some older configurations.
- set a graphic-context for border when double-buffering is
active; to prevent the border color from changing when
switching to reverse-video.
- build-fix for
--disable-ziconbeep, which
conflicted with the new double-buffer configuration (report by
Brian Lindholm).
- fix loop-limit for lookup of
fullscreen
resource broken in xterm #347 (report
by Scott Bertilson).
- update window-manager hints when exiting Tek4014 mode
(Debian #932569, patch by Jonathan Irwin).
- fix a misformatted printf in
report-sgr.pl.
- add configure check for termios types, to improve
compiler-warnings.
- ensure that when resetting margins, to also reset
DECLRMM. This affects DECCOLM,
DECALN (although DEC STD 070 mentions only
top/bottom margins), and DECSTR.
- corrected order of reset/move when setting
DECCOLM, and make it more consistent by always
resetting margins, rather than only when the mode is changed
(report by James Holderness).
- compile-in double-buffer support by default, changing the
configure option to set the default resource value for
buffered to true or false.
- take in account the reverse-video state when computing the
filler-color used when clearing the screen in double-buffering
configuration.
- correct logic for filtering scrollbar-updates when
buffered resource is compiled-in but not enabled
(report by Paul Lampert).
- improve state saved/restored for cursor-save and SGR stack
features.
- improve description of 1006 and 1005 mouse modes, to avoid
implying that they use character-parameters (report by Bryan
Christ).
- explain in
ctlseqs.ms that some of the numeric
keypad keys were xterm extensions rather than VT100/VT220
terminal features (prompted by discussion with Thomas
Wolff).
- explain in
ctlseqs.ms how the DEC windowing
extension is supported by xterm.
- add 28 rectangular editing to the primary response
(suggested by Thomas Wolff).
- fix a typo, improve wording in
ctlseqs.ms
(Thomas Wolff).
- fix internal column-parameter when
SL or
SR is used with left/right margins (patch by
Thomas Wolff).
- fix off-by-one in VT52 graphics character mapping (patch by
Thomas Wolff).
- use
_X_UNUSED, etc., when available as a
fallback for GCC_UNUSED, etc., to reduce compiler
warnings when building with imake.
- update config.sub
- fix a few minor bugs found with Coverity.
- improve double-buffering for scrollbars combined with
scrolled text; add
bufferedFPS resource to control
the maximum rate of screen updates (report by Mike
Thornburg).
- improve fixes for
DECCRA handling of
double-width characters (patch by Martin Hostettler).
- improve discussion of ECMA-48's typographical error for
SD in ctlseqs.ms (prompted by report
by Martin Hostettler).
- correct off-by-one in parameter limit-check for
DECCRA (report by Martin Hostettler).
- modify
saveCellData to handle case where
double-width character is partially copied; that should be
blanked (report/testcase by Thomas Wolff).
- add resource
buffered to allow
enabling/disabling double-buffered mode.
- two fixes for the double-buffer configuration, prompted by
MacPorts' switch to double-buffering (patch by Mike Thornburg,
MacPorts #58313):
- ensure that the needSwap flag is set after drawing
TrueType text
- corrected the drawable-parameter used for the
bar-cursor
- modify
ScrnRefresh to ignore a case where the
left/right halves of a double-width character have been set to
different video attributes. The attribute to use is in the
left-half (report/testcase by Thomas Wolff).
- correct a limit-check for
DECCRA in case the
target lies off-screen (report/testcase by Thomas Wolff).
- documentation errata (report by Thomas Wolff).
- reset flags including wraparound and reverse-wrap when
switching to VT52 mode, while noting that DEC's standard
documentation leaves that behavior undefined (report
by Thomas Wolff).
- ensure that italic font is turned off on hard/soft resets
(report by Martin Hostettler).

active-icon is enabled, since
CSI13t uses
the window-manager name (report by Glenn Golden, Arch
#62818).
- trim a stray “experimental” in one of the
comments about the tcap-query feature, which has been a
supported feature since 2008 (see patch
#238).

the
renderFont resource to match the behavior in
patch #261 (Debian #862042).

default terminal emulation is VT420 (suggested by Thomas
Wolff).
- modify treatment of
reverseVideo for dynamic
colors to make text foreground/background consistent with the
cursor color (prompted by discussion with Ben Wong, lsix
#20).

useBorderClipping as an
alternative to useClipping (request by Robert
Ross).

vttests/sgrPushPop2.pl to illustrate how
selective pushes work, as well as to demonstrate push/pop of
the various color types supported by xterm.
- fix a special case in
XTPOPSGR where
direct-colors were not checked as a dependency of
indexed-colors, contrary to documentation.
- reduce buffer-flushes for
OSC 4 and
OSC 5 color-queries, as well as in the
queries for dynamic colors.
Note: this change makes the reply for
OSC 5 use the “5” in the
response; formerly it was mapped to ”4” after
adding the maximum number of colors.
- modify
vttests/query-color.pl to demonstrate
multiple queries in one request.
- update tables of combining and unknown-width characters in
wcwidth.c based on Unicode 12.0.0.
- modify response for
OSC 5 to be

matched the foreground color while the text was displayed in
reverse-video (report by Nuno Silva).

supports only buttons 1-3.
- reduce the number of buffer-flushes for tcap-query
batches.
- modify
tcapquery.pl to demonstrate batch
queries with -q option.
- increase response-buffer size, and make it configurable as

it generates for setting environment variables.
- improve memory-management for parser, to handle response
strings that might occur with
ENQ or when
SRM mode is active (patch by Martin
Hostettler).
- change
Comment text in uxterm's desktop file
to work around a limitation of GNOME's GIO application
(issue
#940). The
documentation reads:
Searches desktop files for ones that match
search_string.
The return value is an array of strvs. Each
strv contains a list of applications that matched
search_string with an equal score. The outer list is sorted
by score so that the first strv contains the
best-matching applications, and so on. The algorithm for
determining matches is undefined and may change at any
time.
- a check of
zIconBeep resource was removed in
double-buffer fix in patch #334. That
is used to decide whether to handle struct-notify events. When
xterm does handle the events, it may negotiate a new
window-size with the window manager. In that case, the
limitResize resource setting limited the new
window-size to the screen-size. Amended that by eliminating the
limit for this special case when double-buffer is configured,
and restoring the check for zIconBeep when
double-buffer is not configured (Debian #919475).
- disallow recursion which could happen if a user configures
the
answerbackString resource with the
ENQ code and experiments with that code when
SRM is enabled (report by by Martin
Hostettler).
- add remaining credits in
COPYING file.
- modify
run-tic.sh to check if it is using an
older version of ncurses which does not support large terminal
descriptions, and if so, remove a non-essential feature to keep
within the 4096-byte legacy limit.
- modify
run-tic.sh to prefer ncurses6 over
ncurses5, when available.
- add
COPYING file, and dummy "check" makefile
rule for testing Arch packages.

testing.
- update tables of combining and ambiguous-width characters
in wcwidth.c based on Unicode 11.0.0.

versus highlighting (prompted by discussion with Martin
Hostettler).
- restore/repair
keepClipboard feature which was
broken by changes in patch #338
(report by Martin Hostettler).
- improve documentation for
deleteIsDEL
resource.

cases where the resource
deleteIsDEL is initially
neither true nor false, but dependent upon the keyboard type
(report/analysis by Martin Hostettler).

data when switching facename with an escape sequence (report by
Robert Ross).

limitFontsets which can
be used to limit or disable the new TrueType fontset feature
(request by Robert Ross).

protocol, and 15 in the extended mouse-protocol (patch by
Martin Hostettler).

mouse-codes sample script (patch by Martin
Hostettler).
- disable a supplementary check added in patch #341 which interferes with using
fontconfig to select different-sized bitmap fonts (Arch
#61237).
- add options to
mouse-codes script to
demonstrate that the encoding used for mouse events limits
button numbers to 11.
- allow mouse button numbers up to 11 using an offset of 128
for button numbers 8-11 rather than the offset of 64 used for
wheel-mouse, etc., buttons 4-7 in patch
#338 (adapted from patch by Martin Hostettler).
- correct off-by-one right-margin checks for double-width
character adjustments in DECERA/DECFRA (patch by Martin
Hostettler).

freeing the buffer in patch #338
(report/analysis by Stefan Assmann).
- modify the initial pattern passed to fontconfig to disallow
color bitmap fonts.

the requested pattern due to override in the user's font
configuration (report/testcase by Stefan Assmann).
- suppress a spurious warning about fontsets when
initializing menus for the toolbar configuration.
- fix some strict compiler warnings.
- improve checks for TrueType font, to help with the case of
color bitmap fonts, which fontconfig misrepresents (Arch Linux
#58706).

CF_GNU_SOURCE macro to treat
newlib as similar to glibc, fixing a problem
with the configure checks for pseudoterminals in Cygwin
overlooked in patch #334 updates for

for bracketed paste are not sent while processing a selection
for
exec-formatted (Debian #913237).

when doing vertical scrolling within left/right margins (patch
by Martin Hostettler).
- modify wcwidth to encode a few spacing combining marks as
regular combining characters.
- change compiled-in default for
saveLines to
match the resource-file changed in patch
#192 (Debian #913815).

faceSize to 8.0, to simplify
switching back/forth between bitmap fonts and TrueType. This
was originally (mis)set to 14.0 in patch
#148.
- add fallback support in Xft configuration for missing
glyphs (prompted by discussion with Mike Burns).
- fix a problem with using direct-colors for the background
color when clearing/scrolling (report by Nicholas
Marriott).
- add a "sources" rule for the makefile's generated
source.

consistency (prompted by discussion with Martin
Hostettler).
- adjusted ifdef's so that the paste64 configure option does
not automatically enable the readline-mouse configure
option.

different selection targets, and instead modify selection
storage so that different concurrent requests for different
selection targets will be stored/retrieved independently
(Debian #901249).

the documented 4/5 for wheel mouse, and add a script
mouse-codes which makes a report showing the
various mouse codes for different button/modifier combinations
(discussion with Přemysl Janouch).

DECRPTUI, change number of digits
to match VT420.
- revise
omitTranslation resource, e.g.,
splitting “default” into several more useful
categories.
- modify mask-logic to permit control- and
meta- modifiers to be used in mouse protocol.
- several fixes for parsing/state (report/testcases by Martin
Hostettler):
- remove an old/unimplemented entry for xterm-title from
state table.
- save/restore wrap-flag when scrolling, to fix an
inconsistency between jump-scrolling and
normal-scrolling.
- improve a special case of wrapping where the cursor

last-column before the settable-margins can take
effect.

relative to the left margin.
- when scrolling a line within left/right margins,
correct order of the fixups needed when a double-width

- correct a discrepancy between locator-reports for VT220 vs
VT330.
- add window-ops control sequences to complement existing
ones for reporting window-position and text-area size with
reports for text-area position and window-size.
- display vt52 graphics mode characters.
- correct case-statement for window-ops 10, overlooked since
some window managers equate vertical-maximize and
horizontal-maximize window hints with full-screen
maximize.
- add a
GetChecksum item to
disallowedWindowOps
- improve notes in
ctlseqs.ms which mention
where various controls originated.
- add control sequences for querying the X display size and
the character size, both in pixels to help eliminate some of

- add a null-pointer check and a limit-check in
xtermCheckRect.
- correct limit-check for right-margin when processing

discussion.
- fix typo in this change-log (report by Sven Joachim)
- update config.guess, config.sub
- add workaround for improper grayscale adjustments made in
FreeType library, exposed by changes to rounding in 2.8.1,
which shows up as a gap in line-drawing characters (Debian
#880407).
- improve a special case where a non-Unicode font's
line-drawing characters were not used, when specifying it via
the
utf8Fonts resource, e.g.,
-fs 15 \
-xrm '*VT100.font:12x24' \
-xrm '*VT100.boldFont:12x24' \

keepClipboard resource setting and corresponding menu
entry.
- fix an inconsistency between private mode 12 (the AT&T
610 cursor blink) and
DECSCUSR: the former relied
on having the cursorBlink resource set initially
to enable the escape sequence, while the latter does not.
- add private modes 13 and 14, as well as resource
cursorBlinkXOR to allow better control over the
cursor-blinking state (discussion with Bram Moolenaar).
- modify the html and svg screen dumps to support direct
color
- modify media copy (screen-printing) to support the same SGR
codes as
DECRQSS, including 88/256 indexed color
as well as direct color.
- improve options-parsing for query-status.pl script.
- modify parsing of
SGR direct-color control
making color space identitier optional. The
corresponding DECRQSS reply always returns an
empty (default) field for the identifier.
- add wide-attributes to
DECRQSS reply for
SGR.

maximum width when no ISO-8859-1 glyphs are provided (Debian
#879936).

regex
option for onXClicks resources (report by
Lukas Mai).
- add
directColor resource.

by anonymous “Nibby Nebbulous”).
- improve legacy/NRC character set mapping (patch by Thomas
Wolff), e.g.,
- enable alternate NRC set designators for French and
French Canadian, ‘9’ and ‘f’
respectively, as documented in ctlseqs. (‘9’ is
documented for VT510, ‘f’ is a Kermit
feature).
- correct the Unicode value in the DEC Technical
table to show capital delta.
- referring to
http://vt100.net/docs/vt220-rm/table2-3b.html
http://vt100.net/docs/vt320-uu/appendixe.html

alter the Unicode values used for 0x2b through 0x2c to
use curly braces to work with the
“middle” parts displayed with 0x2f and
0x30.
- modify the VT220 “Supplemental” table,
giving a hint that it was probably meant to be
“Supplemental Graphics” and is the same as
VT320's table.
- quiet a few font-warnings when a derived fontname cannot be
opened, overlooked in refactoring of font resources in patch #328 (initially reported on Cygwin
mailing list, with followup).
- correct error response for
DECRQSS broken in
cleanup of Coverity reports in patch
#288 (reports by Bram Moolenaar and IWAMOTO Kouichi).
- improve
DECRPM responses by returning mode
not recognized for modes which may not be settable due to
the selected decTerminalID resource (report by

changes introduced in patch #277, and
relying upon ncurses RGB
extension.
- modify
xterm-new terminal description to use
ECMA-48 REP, reflecting its use in xterm since
patch #32 (1996).
- clarify comment in ctlseqs.ms regarding blink: it has been
part of xterm since patch #60
(1998).
- update ftp URLs in documentation.
- updates for ReGIS (Ross Combs):
- remove redundant text command error check which broke
T(B) and T(E).
- retain the loading alphabet number across multiple
“L” commands.
- add
S(T) delay handler.
- fix some color handling error messages.
- add stubbed-out macrograph handling.
- use
fragment_remaining() and
fragment_consumed() instead of manually
checking position / length in various places.
- rename some local variables in string / extent / option
parsing
- wrap some long lines.
- move macrograph command handling out of the
top-level.
- add a summary of the italic fonts loaded to
-report-fonts option.
- modify the font-lookup for italics to allow for
“
-i-” if no match is found with slant
“-o-” (prompted by patch by Ben
Wong).
- change default values for
mkSamplePass and
mkSampleSize to reflect generally-improved locale
support in various operating systems (FreeBSD #219800).
- modify
wcwidth.c to return -1 for non-Unicode
values, and adjust a couple of blocks to better match
assumptions about ambiguous-width characters in other
implementations. Also modify wcwidth.c to support
configurable soft-hyphen, so there is no drawback to using this
version rather than a system wcwidth.
- amend change made in patch #328
for cursor-visibility to handle case where an application is
updating the reverse-video state (FreeBSD #219800).
- update tables of combining and ambiguous-width characters
in wcwidth.c based on Unicode 10.0.0.
- build-fix for
--enable-sixel-graphics without
--enable-regis-graphics (reports by Sven Joachim,
FreeBSD #219945).
- add control sequences for reading the Sixel and ReGIS
graphics sizes (suggested by Ben Wong).
- add a workaround for
wcwidth returning -1 for
characters which should have been printable (FreeBSD
#219800).
- fix a bug in font initialization from patch #328 (FreeBSD #219800).
- fix a special case in
HideCursor which
assigned a bold font to the slot used for normal font in
changes for italics in patch #307
(Debian #858304).
- updates for ReGIS (Ross Combs):
- Strings specified with no command are used as
"comments". Print these in the log when tracing.
- Catch attempts to use "alternate display" mode (AKA
"blink") from the GIGI, but do not implement it.
- The
T(M) command should only multiply the
height by 10, not 20.
- Make the
S(E) command reset more state
than just the screen contents.
- Remove two rotation variables which were only being
printed.
- Numerous minor fixes and comment updates in the
R command.
- Unknown
R command option names trigger an
empty response.
- Fix the output position after printing rotated text (it
was missing the the sign before).
- Fix the position change with pixelvectors and rotated
text (the rotation transform was not being applied).
- Update the TODO list and remove a verification
FIXME (slanted text positioning is correct as
is).
- Emulate the approximately 1.4x enlargement for text
which isn't rotated at right angles.
- Only update the color planes specified in the plane
mask (the
W command's F
option).
- fix a bug introduced by the changes to font information in
patch #328. When processing the
"checkfont" option of the
locale resource, the
program referred to the request data, to an array
which was only allocated in the new/result widget
(report by H Merijn Brand).
- fix a missing assignment initialization to make the
utf8 resource control whether escape sequences to
enable/disable UTF-8 mode are allowed.
- revise parser for
charClass resource, making
these improvements:
- accept octal and hexadecimal values
- allow embedded whitespace
- allow the class after colon to be optional, e.g., to
clear class settings for a range of characters.
- add command-line option
-report-charclass.
- fix most lintian warnings about test-package
- add
eraseSavedLines resource.
- document
DECSED 3 in
ctlseqs.ms (report by Ben Longmans).
- improve integration between configure-events and updates
for reported screensize, in particular when switching between
vt100 and tek4014 modes.
- modify selection-highlighting of reverse-video text to keep
that distinct, e.g., by reversing the selection foreground and
background colors as one would expect. This fixes a "useless"
case in the description of
highlightColorMode.
- improve fix for Debian #759734, addressing a case where
non-colored cursor would be invisible against reverse-video
(see patch #311).
- updates for ReGIS (Ross Combs):
- the "H" option of the "T" command should multiply by
10, not 20.
- display unknown glyphs as a solid block.
- given a succession of text-direction options, use the
last.
- fix the direction of ReGIS slanted text so that
negative values produce oblique output .
- fix the ReGIS text direction option to only rotate
characters when no following size option is used.
- update terminfo to better match corresponding entries in
ncurses, e.g.,
u8 pattern to match the VT220,
VT420, etc., primary responses, as well as adding
smxx and rmxx.
- fixes from Jörg Sommer:
- corrected a trace-message regarding maximum
graphics-size; it used the similar ReGIS maximum size which
might not be configured.
- in
do_select_regex, clear selection if
there is no match. If the regex does not match anything
around the cursor, the selection returned must be empty,
otherwise the whole line is treated as a match. This way
the command defined by exec-selectable will
not be executed if there is no match.
- modify limit in
do_select_regex to include
the character at the cursor in the match, making it easier
to type something and then hit the key to trigger
exec-selectable.
- If
exec-selectable or
insert-selection is triggered by a mouse
button click, the position of the mouse pointer should be
used. This makes it easier to address any position on the
window and it makes it possible to use the mouse, e.g., for
applications such as mutt where you cannot move the
cursor.
- modify
DECRC to save/restore xterm's
last-column flag used to control wrapping behavior rather than
manipulating DECAWM (report/analysis by Mattias
Engdegård).
- add configure option
--enable-terminfo-env to
use the value set by --with-own-terminfo for the
$TERMINFO environment variable. That variable was
set automatically for HPUX, but would be useful in other
systems, e.g., for Solaris (request by Jeff Wieland).
- fix a race condition when setting up a signal handler to
timeout if opening
/dev/tty hangs (patch by Tobias
Stoeckmann).
- review/cleanup resources which were not in the manual page
(report by Maxwell Anselm):
- add manual page description as needed.
- drop resource name for
menuBar, as
unnecessary.
- modify fallback numeric value for
regisScreenSize resource to match that for
maxGraphicSize.
- updated configure macros
CF_ADD_CFLAGS,
CF_CC_ENV_FLAGS, CF_GNU_SOURCE,
CF_MATH_LIB, and CF_XOPEN_SOURCE from
other program-changes.
- update config.guess, config.sub
- change “maximum screensize” assumed by
resize to 9999x9999, to accommodate people using
the Unreadable font.
- drop
Utility from default value of
--with-desktop-category (Debian #780176).
- widen the configure script pattern used for finding related
".desktop" files, including “Terminal”
- several minor improvements to font utility functions:
- provide for later modification to implement font-sets
by parsing the font resources as comma-separated
lists.
- parse
-fn and -fa similarly,
using “x:” and “xft:” prefixes for
font name/family strings to distinguish between XLFD and
Xft font specifications.
- use loops to iterate over font classes
- use getters/setters for font data to allow for
on-demand lookups.
- make the debugging trace for missing glyph less verbose
since that interferes with the
-report-fonts
option.
- refactor
xtermLoadFont to make it clearer
how some fonts are derived from others, e.g., bold,
wide.
- make the triggering and suppressing of font-warnings
more consistent by storing the last state in the
widget.
- reduce font-warnings by checking for repeated
warnings.
- add
vttests/query-status.pl
- add
vttests/closest-rgb
- add special case for displaying soft-hyphen if it happens
to fall at the right margin, and omitting similar case such as
the BIDI markers, where a zero-width character is neither a
control character nor a combining character (Debian
#844325).
- modify logic for
OSC 52, manipulate
selection data, to update the selection-time to include
the latest X events. This fixes some cases where the selection
was invalid, e.g., after an event due to focus-follows-mouse
(report/testcase by Stephane Chauveau).
- revise macro
CastMallocN as new macro
TextAlloc to make explicit use of
sizeof(char) (prompted by patch by Cade
Foster).
- add “Mouse Ops” menu entry and related
resources to allow runtime disabling/enabling of the mouse
protocol escape sequences (discussion with Bob Proulx).
- improve discussion of mouse actions versus protocol in the
manual (discussion with Bob Proulx).
- improve discussion of environment variables in the manual,
pointing out where some features (such as termcap and the
System5
COLUMNS and LINES variables)
are used rarely, mainly to support legacy applications.
- add examples of
translations resource for
select/paste, and for font-size changes to the manual.
- minor reordering of some entries in
ctlseqs.ms
for consistency (report by Arran Ubels).
- add
-s option to 256colors2.pl
and 88colors2.pl, to demonstrate modifying the
“system” colors 0–15.
- omit
XFT_SPACING property from call to
XftPatternBuild, to work around a bug in
fontconfig for handling Google Go fonts, whose names
sort in an order not expected by fontconfig, causing
the request for a monospaced font to return italics,
e.g.,
$ fc-match 'Go Mono:spacing=monospace'
Go-Mono-Italic.ttf: "Go Mono" "Italic"
(report by Giacomo Boffi on Stackoverflow).
- modify
minstall.in to improve a workaround
added to the manual page in patch #182
to avoid having the C preprocessor used in the imake
configuration strip out the comments in the character classes
section (reports by Ted Unangst, Anthony J Bentley).
- add a check in the function which handles end-of-line
wrapping to ensure that C1 controls are allocated one column
when
allowC1Printable is set (Debian
#738794).
- use consistent error-checking after
strtol
calls, fixes a case where a query with OSC 6 did not ensure
there was a valid color number (report by Alex Smith).
- add
-baudrate option, for testing
ncurses.
- always generate the
CASE_xxx symbols
in VTparse.h and Tekparse.h, as part
of a change to improve debug-logging. This makes the build
always depend upon awk.
- modify
allowC1Printable to disallow codes
160-254 as being equivalent to codes 32-126 when parsing escape
sequences (Debian #839220).
- amend fix from patch #326 for
TrueType fonts to exclude the hidden character used for
double-width cells (report by Grady Martin).
- fix a typo in
ctlseqs.ms
- updated appdata file (report by Richard Hughes).
- improve discussion of the different terminal emulations
provided by xterm in the manual page.
- add examples of setting the icon title with/without the
window title in the manual (Debian #833984).
- correct a limit-check when using a numeric value for
extended Booleans e.g.,
*fullscreen:3 rather than
a name such as *fullscreen:never.
- add action
allow-bold-fonts
- improved formatting fixes for manual page, using script to
find mismatches in spelling of resources, actions and menu
entries.
- improve documentation of logging resources.
- fix a special case of flickering cursor by adding
GraphicsExpose to the list of event types that
should not trigger making the mouse cursor visible (patch by
Joe Peterson).
- correct initialization of line-drawing in VT52-mode,
overlooked in changes for patch #297
(report/patch by Ben Wiley Sittler).
- minor clarification of form-feed versus line-feed in
ctlseqs.ms (suggested by David Kemper).
- amend fix for Debian #738794 to restore a check for missing
characters which are not combining characters. Also
fill in a corresponding special case for TrueType fonts (Debian
#827905).
- improve manual page discussion of function keys (discussion
with Ross Combs).
- further improve fix for Debian #545220 in patch #248, to avoid conflict with combining
characters (Debian #738794).
- improve
-hold option to avoid 100% CPU usage
with NetBSD after closing the shell, which makes subsequent
checks for X input events fail (prompted by patch by Pierre
Pronchery).
- review
#ifdef statements, listed those which
do not have a configure option in
xtermcfg.hin.
- fixed one case where the menu sensistivity for
Print-All Immediately and Print-All on Error
was not properly ifdef'd.
- modify terminfo entries for 16-, 88- and 256-color to reset
palette with
rs1 capability.
- accept
legacy value of -kt as
synonym for the oldXtermFKeys resource, and extend
the full-reset logic to use the keyboard type set via
-kt.
- modify
ioctl calls for I_PUSH to
first check if the module has been added, using
I_FIND. This is needed for newer Solaris libraries
with c11 support (adapted from patch by Alan Coopersmith).
- add check in
getXtermCombining to ensure that
combining characters were allocated (report by Tor
Andersson).
- add configure option
--without-xinerama to
allow suppressing the extension (Gentoo #580936).
- update keysym2ucs.c based on Unicode 9.0
- fixed most
cppcheck --enable=all warnings,
including for style (prompted by report by David Binderman).
There was one bug-fix:
- RGB least-squares computation in
allocateClosestRGB used only one ordinate
- add
cppcheck to lint-like programs in
configure script and makefile.
- fix some const correctness issues and point out an array
lifetime issue (Ross Combs).
- updates for SIXEL and ReGIS (Ross Combs):
- Sixel drawing should still happen after an error if
some commands have been processed
- Tiny steps toward reporting ReGIS input
- updated configure macro
CF_LD_RPATH_OPT from
ncurses changes.
- provide alternate fix for Juha Nurmela's report by turning
on POSIX signals if
_POSIX_C_SOURCE is at least
one. This is done to improve the behavior if a direct child
process receives a STOP signal.
- revert change to
CF_POSIX_C_SOURCE from
patch #323 (reports by Ashish Shukla,
Christian Weisgerber).
- updated appdata and desktop files to add keywords (report
by Richard Hughes).
- modify configure macro
CF_POSIX_C_SOURCE to
accommodate some systems, e.g., FreeBSD, which have separated
their implementation specific preprocessor symbols from the
POSIX ones, requiring both to be defined (report by Juha
Nurmela).
- change the directory to the current working dir of the
child process in exec-formatted and exec-selectable actions
(patch by Alexander Pohoyda).
- correct typo in xterm.man (patch by Larry Hynes).
- correct typo in ctlseqs.ms (report by Shriramana
Sharma).
- add feature to support XHTML and SVG screen dumps (patch by
Jens Schweikhardt).
- correct response to DECRQSS when terminal id is less than
400 (patch by Iwamoto Kouichi).
- fix regression due to incorrect fix for compiler warning
when allocating storage for
/etc/shells (reports
by Ashish Shukla, Debian #809646).
- add resource
keepClipboard, escape sequence
and action keep-clipboard.
- add optional feature to capture text copied to clipboard at
the time of copying rather than at the time the clipboard
contents are requested for pasting (patch by Milan
Mehner).
- improve a special case where the
-e option was
used to pass a single-quoted command via luit, by
wrapping it in a “sh -c” (report by Keith
Hedger).
- minor fix for type-cleanliness when allocating storage for
/etc/shells (Tobias Stoeckmann).
- fix a typo in manual page (Dan Church).
- fix minor file-descriptor leak; after calling
openpty, the slave's file descriptor is not needed
(report by Juha Nurmela).
- editorial change to ctlseqs.ms (report by David
Gomboc).
- minor updates for autoconf macros.
- update config.guess, config.sub
- correct documentation for
%t format (report by
Martin Tournoij).
- add
%R for consistency to
exec-formatted() and
insert-formatted() actions.
- add
%r format to exec-formatted()
and insert-formatted() actions (patch by Martin
Tournoij).
- Amend fix for Debian #7
