How to modify the buffer height when debugging the console exe??

[wxuefei]

Description of the new feature/enhancement

I can modify the console buffer height use the below code when I debugging the console exe with VC & cmd, but it doesn't work in WindowsTerminal, the buffer height seems always is 9030, how to modify it ?

system("mode con:cols=120 lines=20000");

or

SetConsoleScreenBufferSize(GetStdHandle(STD_OUTPUT_HANDLE), { 120,20000 });

Proposed technical implementation details (optional)

This isn't something that's possible with the Terminal, or really something we're planning on supporting. Out of curiosity, why would you like to change the history size at runtime from a CLI application/?

(changing the windows dimensions is tracked in #5094, but that's definitely not the buffer height)

When you debugging an exe that outputs a lot of logs, you will need it ! Why cmd works well ,but windowsterminal doesn't? is it very diffcult?

[zadjii-msft]

Yea, but this doesn't really seem like something that needs to be changeable at runtime, from a cli application. I'd just slap a "historySize": 99999 in my settings.json, and forget about it. That'll just max out the history size, and you'll never need to think about resizing it again.

Am I missing something?

OK！ I got it ! There are two “historySize”, one in defaults section, it be used for debugging terminal window, another historySize in list{cmd} section, it be used for terminal shell. Thanks !
