Log output is not coloured in GitHub Actions (hashtag604)

[vikramsubramanian]

I have found that log output is coloured when running locally but not when running through GitHub Actions. Is there something I need to do to get colour in GitHub Actions?

I noticed in a comment here: that "humanfriendly.terminal.terminal_supports_colors actually returns False on the github runner (ubuntu-latest)". Could that be the problem?

GitHub Actions does support colour eg. from another logger:

By default, Loguru tries to automatically detect whether or not the terminal supports colors. Maybe this is a false-negative case.

You can force colored output by adding you sink with colorize=True. Does it work better?

[vikramsubramanian]

Thank you, that worked eg. see [this](

You could fix the false-negative case by detecting the environment variable: GITHUB_ACTIONS Always set to true when GitHub Actions is running the workflow. You can use this variable to differentiate when tests are being run locally or by GitHub Actions. (from [here](

Great, I will do that, thanks. :+1:

Why are some logs not colored in the Github Actions output you shared, though? Is it due to InterceptHandler or something?

[vikramsubramanian]

That script is using the standard logger and then imports another library of mine where the InterceptHandler is set up so I guess it is because of that.

I guess it would go here:

        if any(x in os.environ for x in ("PYCHARM_HOSTED", "GITHUB_ACTIONS")):
            return True

Fixed on master branch. :+1:
