Title: cbTerminal plugin to access terminal from the bottom panel for Linux ( wxGtk )
Post by: christo on December 31, 2024, 05:40:45 am
https://github.com/josephch/cbTerminal is a small plugin to show bash terminal using VTE Gtk widget. It might be useful for Linux users.

Nice work.

My question is that can you bring such feature to Windows OS?

Thanks.

@ollydbg, I've tried TerminalWx (https://github.com/jeremysalwen/TerminalWx), which I believe is cross-platform. I decided to go with VTE because it appears better in my Ubuntu. My work to integrate TerminalWx is available in https://github.com/josephch/cb-TerminalWx . For Windows, you can try changing cbTerminalView_TerminalWx.cpp to use the correct terminal.

Hi, sorry for the late reply, I'm busy these days.

I have made a new fork of your repo: asmwarrior/TerminalWx: WxWidgets Terminal Widget (https://github.com/asmwarrior/TerminalWx), and try to build this library with the C::B and msys2.

I see some link errors

I'm not sure how difficult the windows conpty API is. I haven't tried it yet.

OK, the linker error issue is fixed, I have pushed to my git fork.

Now, when I run the program, I see below screen shot, but I can't enter any chars to the terminal window.

@ollydbg, by default nothing will be shown. You have to integrate a pseudo terminal, then only the widget will be useful. Also please refer https://github.com/josephch/cb-TerminalWx/blob/dfad6bd1922b70af7f9d33f09fbd51bf7608710f/cbTerminalView_TerminalWx.cpp , you can see how data is read and written to the terminal emulator.

I tried, and derived a new class named "TerminalWxWin", and it use the winpty library from msys2/mingw.

The final result is: some text is shown in the main frame, see below, but still far from usage, I can't enter any text, and the input text does not show fully.

See image shot below.

I have push my changes to my code repo: https://github.com/asmwarrior/TerminalWx

Thanks, Christo

Thanks, actually, that code is created by some AI, and I know little about how the terminal works.

I create an issue about the reading of the console text here with some of by debug result.

Windows console text does not show correctly  Issue #1 asmwarrior/TerminalWx (https://github.com/asmwarrior/TerminalWx/issues/1)
