设置另一个进程的终端大小(如ala`stty columns`)?

I'm using the package to create a pseudo-TTY for external processes I spawn off. However the terminal size for them seems to be smaller than the terminal emulator window size (ie ncurses and other terminal UIs will only draw in the top left corner of xterm / Konsole / whatever).

I have raised a bug with the pty package as the idea way to fix this issue would be with the package itself, but as a work around it might be handy if I could set the dimensions of the TTY myself (in code).

How would I go about doing this?

NB The project is written in Go (Golang) so ideally I'd need advice in doing this in C or Go. Also the project I'm working on has a strong emphasis on cross platform compatibility so it would be handy to know if any syscalls required are OS specific.

我正在使用 包创建伪 -TTY我生成的外部进程。 但是,它们的终端大小似乎小于终端仿真器窗口的大小(即,ncurses和其他终端UI只会在xterm / Konsole /左上角绘制)。



NB该项目是用Go(Golang)编写的,因此理想情况下,我需要在C中进行操作的建议 或去。 另外,我正在从事的项目非常强调跨平台兼容性,因此,很容易知道所需的系统调用是否特定于操作系统。

    I found the solution. Turns out creating a new pseudo-TTY was the wrong approach and I can actually use the standard Go libraries to achieve what I wanted:

    cmd := exec.Command(name, parameters...)
    cmd.SysProcAttr = &syscall.SysProcAttr{
        Ctty: int(os.Stdout.Fd()) // set the TTY
    // These must be the respective Std os.File as using a Reader/Writer 
    // wouldn't work if you're trying to assign a TTY to your terminal
    // emulator.
    cmd.Stdin = os.Stdin
    cmd.Stdout = os.Stdout
    cmd.Stderr = os.Stderr
