GoLang OS / exec StdoutPipe颜色

Question

I'm making a wrapper for a minecraft server console with GoLang. It uses os/exec to run the server and process.StdoutPipe() for realtime output from the subprocess.

But, I can't get it to display the colors for some reason. When I run the server directly from the terminal, colors work, but it doesn't work at all when I run it from GoLang.

What's more is there's no color codes on the log files either when I run it from GoLang. But running it directly from the terminal, the log file is absolutely messed up with color codes. I really don't get how that happens.

Is there any way to fix this?
Thanks!

The way to fix this is to force colors from the minecraft server. It's not a problem with your Go program at all. It's very common for command-line programs to detect whether they're running on an interactive terminal, and disable certain features (such as color output, paging, etc) when they are not, under the assumption that they're being passed through a script (as indeed it is, in your case).

If the minecraft server doesn't have this option, you may be able to fool it into thinking it's running on an interactive terminal.
