c++ - 我可以在处理它时保留编译器输出的格式吗？

Question

每当我调用 run GCC 时，它都会很好地格式化其输出(使文件名加粗、注释标签为白色、错误标签为红色等)。但是，当我想重定向它并仍然保持显示时，格式就消失了......

例子:

make                                    # The display is formatted
(...)
make |& tee >(xargs echo > example.out) # The display is not formatted
(...)

如何在保持原始显示格式的同时重定向输出？

文档说(文件:gcc-6.info，节点:诊断消息格式化选项):

-fdiagnostics-color[=WHEN]

Use color in diagnostics. WHEN is never, always, or auto. The default depends on how the compiler has been configured, it can be any of the above WHEN options or also never if GCC_COLORS environment variable isn't present in the environment, and auto otherwise. auto means to use color only when the standard error is a terminal.
