问题描述
os.Stdout os时，该命令非常有用.Stderr os.Stdoutos.Stderr我想将输出和错误输出显示到控制台，但我也希望我的程序查看输出是什么.
I want to display the output and the error output to the console, but I also want my program to see what the output was.
然后我创建了自己的Writer类型，将其写入缓冲区并打印到终端.
I then made my own Writer type that did just that, wrote both to a buffer and printed to the terminal.
这就是问题所在:某些应用程序在检测到未写入tty时，会将其输出更改为人类无法读取的内容.因此，当我以后者的方式进行输出时，输出变得难看.(计算机更清洁，人类更难看)
Here's the problem—some applications change their output to something much less readable by humans when it detects it's not writing to a tty. So the output I get changes to something ugly when I do it in the latter way. (cleaner for computers, uglier for humans)
os.Stdout/os.Stderr script os.Stdout/os.Stderrscript提前谢谢！
推荐答案
The only practical way to solve this is to allocate a pseudo terminal (PTY) and make your external process use it for its output: since PTY is still a terminal, a process checking whether it's connected to a real terminal thinks it is.
github.com/creack/pty github.com/creack/pty下一步是让实现PTY的程序包实际分配它，并将PTY的另一端"连接到您的自定义编写器.
The next step is to have a package implementing a PTY actually allocate it, and connect "the other end" of a PTY to your custom writer.
