A small tip:
TerminalCtrl can display PowerLine fonts and glyphs
By default, however, if you install and try to use PowerLine fonts, you will notice that some glyphs are missing. This is because U++ handles its fallback fonts through a compile-time list.
In order to utilize powerline fonts, all you need to do is add the following line to the end of fallback fonts lists [sFontReplacements array], in Draw/FontCR.cpp:
{ "PowerlineSymbols", 0x00000000, 0x08000008 },
This method can be applied to other fonts as well. Just use uppbox/FontCover app to calculate the font range for your desired font.
If you recompile U++, set up powerline fonts support and configure apps, say vim, you should get a display similar to the below screenshot(taken via stock TerminalLayoutExample):

Hello,
tldlr:
In the following weeks TerminalCtrl will finally gain winpty support.
This means that it will be able to run as a local terminal ("natively") on Windows XP/Vista/7/8/10, without requiring Cygwin, Msys2 or Win10 pseudoconsole api. 
This idea was brewing for some time as I was investigating the possibility of embedding native windows console support in PtyProcess class.
As it turned out, it was suprisingly trivial, thanks to winpty.
Pros:
1. TerminalCtrl does not require any specific hack or intervention to run on Windows as a local (=not remote) console, thanks to its design and WinPty.
2. Cygwin or MSYS2 are not required. Only the libwinpty (winpty.lib or winpty.dll) and winpty-agent is required and they compile on native CLANG compiler and Windows environment.
3. WinPty's API seamlessly integrates with PtyProcess class and it api. As a result, the existing terminal examples or code using PtyProcess class do not require any modification. A simple compiler flag (flagWINPTY) will be enough to switch it on.
4. This means it is possible run cmd.exe, bash.exe, powershell.exe, or any Windows-native console application (such as FAR file manager - see screenshot below) directly on TerminalCtrl/PtyProcess.
5. This also means that TerminalCtrl can be set to run in CygWin and Msys2 environments, and it can easily replace Mintty, which is, AFAIK, bound to Cygwin or Msys2 subsystem.
6. winpty has MIT license. You can freely supply the winpty.lib and winpty-agent with your application.
Cons:
- Nothing much at the moment, really. Winpty has some small quirks but they arent specific to our terminal emulator widget.
Below screenshot is from the Far file manager. It is running natively on the stock TerminalExample, on Windows 7.

If you have any questions, bug reports, suggestions criticism, etc. let me know.
Best regards,
Oblivion

Hi,
TerminalCtrl now officially supports winpty on Windows platform.
This effectively eliminates one of the major "show-stoppers" we've had up until now with TerminalCtrl: Native console support on Windows XP/Vista/7/8. (ıt can also be used on Win10, but we already have PTY support for that version of windows)
You have two choice here should you select the WINPTY backend:
1) You can compile winpty-agent, winpty.dll and winpty.lib. These files can be easily created, It is not a complicated process.
2) You can use the existing files in your system (for example you can get them from MSYS2 installation or from the GIT Windows client). Just put the agent and dll in the same directory as your terminal app and link your app against winpty.lib (by activating WINPTY flag).
In the process, I made a so-called "course-correction" which unfortunately slightly breaks the existing TerminalCtrl installations: I have removed the PtyProcess code from TerminalCtrl source tree and made it into a separate pacakge.
Thus you will need to explicitly add PtyProcess package and its heeader file to your apllications if you want to use it.
E.g.
#include <PtyProcess/PtyProcess.h>
I apologize for this break, but hopefully this will allow easier maintenance and better separation of code.
Best regards,
Oblivion

Hello,
- PtyProcess package now contains a patched and statically linked version of libwinpty.
- winpty is from now on the default pty backend on Windows platform. No WINPTY flag is required to activate it.
- Since winpty requires an agent executable, I have also added PtyAgent to both TerminalCtrl nest on UppHub and to upp-components/Core.
- After building the PtyAgent, just move the resulting exacutable (PtyAgent.exe) to your apps executables directory.
- Package is tested with CLANG. MSC will follow...
This means that effectively Terminal package -as a local pty- and its examples are now able to run and work on various versions of Windows.
If you have any questions or suggestions, let me know.
Best regards,
Oblivion

Hi,
Terminal package is updated. This update is somewhat big, as the 2021.1 release is imminent.
Consider the below changes as a summary of 2021.1 milestone (v0.5) changes/highlights:
Changes:
* Cell padding (horizontal/vertical) is implemented.
* Missing tester methods are implemented.
+ Display renderer is refactored and optimized.
+ Parser (VTInstream) is optimized, using chunking in addition to traditional state machine. It is ~82% faster on average.on a reference machine.
+ Sixel renderer is refactored and optimized. The renderer's raw performance is almost doubled. From 14 to 27 MB/s on a reference machine.
+ An out-of-bounds crash with dynamic colors feature is fixed.
+ Dynamic colors feature is improved. It can now set/reset multiple colors in a single command.
+ Display refreshing strategy is improved.
+ Local echo now correctly calls the display refreshing methods.
+ A crash when selecting wrapped text lines is fixed.
+ Parser now allows OSC sequences to have UTF-8 payload on UTF-8 parsing mode.
+ SGR mouse tracking mode gained a pixel-level tracking variant.
+ UTf-8 titles (xterm extension) are now correctly displayed and reported.
+ On Windows Vista, 7, 8, 10 PtyProcess now allows native console applications via WinPty.
+ On windows, PtyProcess now defaults to statically linked WinPty backend. (Win10 api stays as the recommended option on Windows ver. >= 10)
+ On windows native console (Via WinPty), TerminalCtrl now correctly refreshes the page size after a window size change.
+ Deprecated "Terminal" alias is now removed.
Only a few more compliance tests and cosmetic changes remain. After that, I'll mark this as 2021.1
Suggestions, bug reports, etc .are welcome.
Best regards,
Oblivion

Compilation problem on Mac while compiling TerminalInWebBrowserExample:
/Users/ssg/worker0/m-upphub-TerminalCtrl/build/TerminalCtrl/Terminal/Keys.cpp:312:89: error: use of undeclared identifier 'K_OPTION_KEY'; did you mean 'K_OPTION'?
if(findarg(key & ~(K_CTRL|K_ALT|K_SHIFT|K_OPTION), K_CTRL_KEY, K_ALT_KEY, K_SHIFT_KEY, K_OPTION_KEY) >= 0)
^~~~~~~~~~~~
K_OPTION
/Users/ssg/dvlp/cpp/code/upp/git/uppsrc/CtrlCore/CtrlCore.h:103:2: note: 'K_OPTION' declared here
K_OPTION = 0x4000000,
^
MacOS can be easily installed in a VM (check for such projects on github).

Hello Klugier,
(I've been changing my job, so I was away for several month. And I am almost back to developing U++ stuff... Nice to see you all. )
All of those mentioned applications AFAIK are compatiable with TerminalCtrl. We even have a video demonstrating the mapscii on TerminalCtrl's earlier versions. (I've tested them all except the twitter app) If you find any problems. let me know.
Even the highly experimental next-gen terminal stuff (notcurses demos, vtm, etc.) are compatible wihh TerminalCtrl. And the new wchar32 will make things even better on the unicode side. (I am going to test it soon)
ATM, TerminalCtrl passes 425 unit tests, and fails on 86 tests when passed as 'xterm'. This is AFAIK one of the highest scores for non-xterm-based VTEs. (results are taken from esctest terminal unit testing suite).
Where Gnome Terminal can pass only 136 tests when disguised as 'xterm' (Not that Gnome terminal is bad, it just does not implement some legacy stuff for old apps and other features)
Not to mention that even Far Manager (a CLI-based TUI file manager on Windows) works on TerminalCtrl.
A side note: I use vim and emacs, htop, ranger on TerminalCtrl regularly.
Best regards,
Oblivion

Hi,
Terminal package will receive a big update in March 2022.
In the meantime, however, I am happy to announce that you can enjoy the brand new enhanced unicode support of U++ (wchar32) in TerminalCtrl, which means the terminal can now display virtually all of the emojis correctly.
The required changes were minor, and already pushed to the both upp-components and Upphub repos, as TerminalCtrl was already designed to work with up ot 32 bit characters from the beginning.
A screenshot taken with vtm, a modern text user interface and terminal multiplexer (running on TerminalLayoutExample)

You can access the free demo of vtm to test TerminalCtrl, using the following command via the stock TerminaCtrl examples:

Just to make sure I tried it again with
tr -dc '[:graph:]' < /dev/urandom | tr -d \''\\'\` | head -c 1G > test.txt
and
For Konsole I got:
real 1m4.362s
user 0m0.017s
sys 0m6.407s
and for TerminalCtrl I got
real 18m33.085s
user 0m0.024s
sys 0m10.896s
rxvt appears to be the fastest I've tested at
real 0m17.997s
user 0m0.004s
sys 0m4.674s
