# 62eadc5e 09-Nov-2016 Jérôme Duval <jerome.duval@gmail.com>

Terminal: implement index and next-line CSI sequences.

* also ignore 0xa, 0xb, 0xc control characters in CSI sequences.


# ecfaa77a 03-Nov-2016 Jérôme Duval <jerome.duval@gmail.com>

Terminal: Implement a few cursor CSI commands.

* Cursor back tab, cursor forward tab.
* Cursor next line, cursor previous line.
* also add size 13 to the list of font sizes.


# 314e8a20 10-May-2013 Ingo Weinhold <ingo_weinhold@gmx.de>

BasicTerminalBuffer: Add {Previous,Next}LinePos()


# 3d149248 03-Apr-2013 Siarzhuk Zharski <zharik@gmx.li>

Fix support of East Asian Full Width characters

* Re-enable full-width characters detection and display;
* Fix cursor drawing on full-width characters;
* Fix debug dump for multi-byte characters;
* Fix file permissions for debug capture log.

Fixes #6717. Also may improve behaviour related to #6227.


# e0fcd629 27-Mar-2013 Siarzhuk Zharski <zharik@gmx.li>

Code style fixes. No functional changes.

Fix for some code style issues pointed out by Axel. Thanks.


# daebca78 21-Mar-2013 Siarzhuk Zharski <zharik@gmx.li>

More standard handling G0,G1,G2,G3 graph.char sets

Handling of graphic character sets G0-G3 is fixed and implemented in
more consistent, extensible way.


# 1dd3b537 16-Mar-2013 Siarzhuk Zharski <zharik@gmx.li>

Fix Alternate/Normal screen's current attributes handling

Handle the current attributes of the TextBuffer consistently with other
Alt/Normal buffer sensitive variables. That fixes, for example, issues
with wrong background coloring of new lines in normal text buffer after
maximizing the terminal window running applications (like MC) performing
output onto alternate screen.


# 5b41331f 09-Mar-2013 Siarzhuk Zharski <zharik@gmx.li>

CodeStyle fixes, some refactoring and cleanup

* Clear some codestyle issues catched by checker script;
* Rename RestartDebugCapture to more consistent StartStopDebugCapture;
* Updated Copyrights and authors lists, some occurences of the raw MIT
licence text replaced with "under the terms of MIT licence" reference;
* Fixes for x86_64 build.

This is cumulative cleanup commit for series of Terminal refactoring
changes I have introduced last time. No significant functional changes.


# b0b7933e 07-Feb-2013 Siarzhuk Zharski <zharik@gmx.li>

Use stack for storing saved cursor positions

That fixes issue with latest versions of Midnight Commander - it
"restores" on exit the latest postion was set, that is equal to 0.0.


# b512213b 31-Jan-2013 Siarzhuk Zharski <zharik@gmx.li>

Support Background Color Erase, switch to xterm-256color

* Lot of fixes to add support of BCE (background color erase). Shell
is switched to emulate xterm-256colors terminal, that is modern and
declare the colors capabilities of our Terminal more precisely;
* Move current character attributes fAttr from TermView to
BasicTerminalBuffer. This reduces count of function parameters on call
various InsertXXX routines;
* In alternative screen buffer mode the whole cells "matrix" of the
screen buffers is taken into account during drawing background of the
cells in the view. In normal mode the "attributes" field of the
TerminalLine is used to detect color of the area after the last
character - there should be no changes with previous behaviour;
* Fix attributes on kSpaceChar-padding short lines. Current _line_
attributes should be used instead of current _global_ attributes;
* Fixed pads and gaps attributes, more accurate handling of ESC[K and K°;
* _Invalidate strings just erased. Fix EraseChars DCH processing;
* Fixes for ESC[J erase lines control sequences;
* Added handling SGR 90-97, 100-107 codes;
* Clean the newly allocated TerminalLine lines;
* More precise cursor background [off-]color estimation at ends of
lines. The current line attributes should be used instead of
hard-coding it to fTextBackground;
* Fixed background color erase in normal screen buffer modes. Wrong
line indexes calculation messed the drawing results or just returned
0 [default] line attributes;
* Some more BCE support: TerminalLine::Clear() now honors current
character attributes;
* Fixes #6143, #6510 and #6424.


# 718a28ce 30-Jan-2013 Siarzhuk Zharski <zharik@gmx.li>

Add Debug snapshots and capture of Terminal data flow

Two helper functions introduced: "make debug snapshots" triggered by
Ctrl-Cmd-S shortcut and "capture data flow" triggered by Ctrl-Cmd-C
shortcut. The first one makes debug dump of current data both in visual
and in text buffer, including history lines if they available. The second
one mirrors all characters and control sequences that are flowing
through the Parser. Both dump and capture files are saved under /var/log
folder. That functionality available only if the USE_DEBUG_SNAPSHOTS switch is
defined.


# a2f89c58 02-Feb-2012 Siarzhuk Zharski <zharik@gmx.li>

[Coverity] Fixed some uninit fields and return values checks

* Fixed CID2398, CID9945, CID9943, CID4215


# 627ced12 28-Nov-2010 Adrien Destugues <pulkomandy@pulkomandy.ath.cx>

Use a better way to store the attributes for end of line. This should also fix some other bugs, as there were occasionalaccess to out-of-range chars.

# a7538599 22-Nov-2010 Adrien Destugues <pulkomandy@pulkomandy.ath.cx>

* Insert an extra space when doing a CR. This ensures the latest attribute setup gets inserted somehow in the line before we go elsewhere.
This gets 256colors.pl to give the right output, as well as useable vim in TERM=xterm-color mode (as far as I can tell).

# 384fe022 22-Nov-2010 Adrien Destugues <pulkomandy@pulkomandy.ath.cx>

* Use the attributes from the parser instead of trying to guess blindly when inserting a tab. This avoids strange things hapenning when a tab is inserted at the start of a line.

When erasing the screen actually erase the screen, not just the scroll region.
Implement all three variants of the EL (erase line) sequence.

Thanks! Resolves ticket #4652.

# 80abc271 14-Aug-2009 Ingo Weinhold <ingo_weinhold@gmx.de>

Changed the Ctrl-L behavior: The current screen is now scrolled up completely
instead of actually clearing it, so that it is still in the history.

# b43255b9 19-Jun-2008 Ingo Weinhold <ingo_weinhold@gmx.de>

Squashed TODO: When writing a character in the last column of a line we
wrapped to the next line and a subsequent LF would advance another line.
We behave like xterm now, i.e. visually the cursor stays on the same
line (on the last character), but the next character will be wrapped to
the next line.

# d04aae8b 17-Jun-2008 Ingo Weinhold <ingo_weinhold@gmx.de>

* Some preparations for DEC private mode settings support.
* Implemented alternate screen buffer support. Not used by any program
yet, since we still use the beterm termcap entry.

# 5d2d3a84 16-Jun-2008 Ingo Weinhold <ingo_weinhold@gmx.de>

* Fixed \ESC[0J (erase screen below). It shall not erase any character
on the line before the cursor.
* Implemented \ESC[1J (erase screen above.
* Fixed \ESC[2J (erase all). It shall not move the cursor.
* When scrolling only the top part of the screen, we do now also
invalidate the line below the scroll region. Otherwise the view
wouldn't know that they have not been scrolled.

# 4c9d4b02 14-Jun-2008 Ingo Weinhold <ingo_weinhold@gmx.de>

* Change the line history to a more compact format. We reserve
lines * (width + 8) bytes which is only a little more than a sixth of
what it was before. The effect on performance is relatively small. In
my tests I measured about 2% slowdown.
* Fixed artifacts after soft-wrapped lines.
* Re-enabled cursor blinking. I changed it so that the cursor is 1s
shown and 0.5s hidden (instead of 1s each). Tell me what you think.

# 90ab7ea3 10-Jun-2008 Ingo Weinhold <ingo_weinhold@gmx.de>

* Added a SetHistoryCapacity() method.
* Added a ResizeTo() version that allows to set the history capacity at
the same time.
* Added a SynchronizeWith() method that allows synchronizing with (a
part of) another buffer.
* Fixed TODO in _Scroll().
* Improved the dirty region update code in _Scroll(). It would in
certain (not exactly uncommon) situations needlessly invalidate the
whole screen.

# 23450280 09-Jun-2008 Ingo Weinhold <ingo_weinhold@gmx.de>

Pulled base class BasicTerminalBuffer out of TerminalBuffer. It contains
pretty much all the meaty code. Left in TerminalBuffer is only stuff
that didn't quite fit, like the encoding and view notifications.

* Some preparations for DEC private mode settings support.
* Implemented alternate screen buffer support. Not used by any program
yet, since we still use the beterm termcap entry.

Added support for \ESC[%dX (erase characters).

* Fixed \ESC[0J (erase screen below). It shall not erase any character
on the line before the cursor.
* Implemented \ESC[1J (erase screen above.
* Fixed \ESC[2J (erase all). It shall not move the cursor.
* When scrolling only the top part of the screen, we do now also
invalidate the line below the scroll region. Otherwise the view
wouldn't know that they have not been scrolled.

* Change the line history to a more compact format. We reserve
lines * (width + 8) bytes which is only a little more than a sixth of
what it was before. The effect on performance is relatively small. In
my tests I measured about 2% slowdown.
* Fixed artifacts after soft-wrapped lines.
* Re-enabled cursor blinking. I changed it so that the cursor is 1s
shown and 0.5s hidden (instead of 1s each). Tell me what you think.

* Added a SetHistoryCapacity() method.
* Added a ResizeTo() version that allows to set the history capacity at
the same time.
* Added a SynchronizeWith() method that allows synchronizing with (a
part of) another buffer.
* Fixed TODO in _Scroll().
* Improved the dirty region update code in _Scroll(). It would in
certain (not exactly uncommon) situations needlessly invalidate the
whole screen.

Pulled base class BasicTerminalBuffer out of TerminalBuffer. It contains
pretty much all the meaty code. Left in TerminalBuffer is only stuff
that didn't quite fit, like the encoding and view notifications.
