如何在捕获的输出(标准输出和标准错误)中保留颜色?

解决方案

许多命令会检测它们是否没有将输出发送到终端"，如果没有，则不会添加特定于终端的代码来显示颜色.当您缺少颜色时就是这种情况.某些 git 命令，不确定所有命令，可以采用 --color 参数 - 检查联机帮助页.

I have a custom Git command implemented in Python that uses methods from the subprocess module to call git. I've noted that, depending on the method used, the output may or may not be colored, e.g.:

import subprocess

subprocess.run('git push origin --delete foobar', shell=True)
print()
print(subprocess.run('git push origin --delete foobar', shell=True,
                     capture_output=True, encoding='utf-8').stderr, end='')

Output:

How to preserve colors in the captured output (both stdout and stderr)?

解决方案

Many commands detect if they're not sending their output to a "terminal" and don't add the terminal-specific codes to display colors if not. That will be the case when you're missing the colors. Some git commands, not sure all of them, can take a --color argument - check the manpages.
