even with
golangci-lint run -v --color always
, we can not make the log level support color.with this option, one can set env var
CLICOLOR_FORCE=1
to skip the tty check and print colored log level.and set env var
CLICOLOR_FORCE=0
andCLICOLOR=0
to disable colored log level.see https://github.com/sirupsen/logrus/blob/85981c045988a3ebe607e2f5b8a6499d86e0ddac/text_formatter.go#L120
