- Handling of incomplete/partial UTF-8 bytes is improved.

- Application clipboard manipulation protocol (OSC 52) is implemented.

1) Terminal ctrl gives the client code a granular control over this protocol.

2) In compliance with the principle of least astonishment, the feature is disabled by default.

3) It will work IFF it is enabled && the ctrl instance has focus (to prevent spamming, etc.)

Terminal package, release: 2020.2, overview:

* Terminal class is finally renamed as TerminalCtrl. (Upp::Terminal will be available as an alias, until 2021.1 (v0.5) release tag).
* Fixed to compile with MSC 19.
* TerminalCtrl now officially supports Windows 10's native pseudoconsole api via the unified, basic interface of PtyProcess class.
* iterm2's inline images protocol is implemented and polished.
* Clipboard manipulation protocol (OSC 52) is implemented.
* Middle-drag (in application mouse-tracking mode) is implemented.
* Right-drag (in application mouse-tracking mode) is implemented.
* Auto-hide option for mouse cursor is added.
* Word selection is implemented. (double-click selection)
* Line selection is implemented. (triple-click selection)
* Text selection mechanism is refactored using the new range-based methods.
* Copy-on-select style text selection is added.
* Text cursor (caret) width is now automatically adjusted to cell width (i.e. reacts to single/double width unciode codepoints).
* Space character can now have overline/underline/strikeout attributes.
* Key handling is further improved across supported platforms.
* Scheduled time callbacks are now properly cleared on object destruction.  (MT-fortification)
* Performance/throughput  is further improved by removing the now redundant calls to page refresh methods.
* Hyperlink tooltips now display the decoded URL.
* RGBA, CMY and CMYK color text specifications (formatting and scanning) is now supported.
* Brightness component of faint colors is now correctly calculated.
* Jsonization and Xmlization support is added.
* More switches are added to the TerminalCtrl.usc (layout file).

* PtyProcess api docs are added.
* TerminalCtrl::InlineImage structure is documented.
- Terminal overview doc is removed.

- The usage of TheIDE's layout editor to set-up the TerminalCtrl's properties and layout.
- Custom menu (bar & context) creation, and manipulation of TerminalCtrl's standard menu
- The usage of xterm's WindowOps (actions) to set up custom display sizes and modes (fullscreen/maximize/minimize, etc).
- A high performance event loop.
- Binary serialization of TerminalCtrl's storable properties and flags.

- Application mouse tracking ("x10/x11") mode now sends the correct mouse coordinates on older wire formats where the max x/y coords is limited to 255 cells, 8-bit). This also fixes vim's mouse handling.

- It is now possible to set the text cursor style (block, beam,underline) of TerminalCtrl via TheIDE's layout editor.

xterm

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.

- Nothing much at the moment, really. Winpty has some small quirks but they arent specific to our terminal emulator widget.

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).

 

#include <PtyProcess/PtyProcess.h>

- 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...

* 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.
