Subject: [PATCH v3 1/1] MdePkg: Use ANSI colors to indicate debug message severity
Date: Fri, 2 Sep 2022 05:23:22 -0600 [thread overview]
Message-ID: <20220902112322.203555-2-rebecca@quicinc.com> (raw)
In-Reply-To: <20220902112322.203555-1-rebecca@quicinc.com>
There currently isn't a way to differentiate the different
levels of DEBUG output: DEBUG_ERROR, DEBUG_WARN, DEBUG_INFO
etc.
To improve this, wrap DEBUG_ERROR and DEBUG_WARN level
messages in ANSI color code escape sequences. DEBUG_ERROR
messages will be displayed in red text, and DEBUG_WARN
in yellow.
Only enable this new functionality if the FeatureFlag
gEfiMdePkgTokenSpaceGuid.PcdDebugAnsiSeqSupport
is set to TRUE. By default it's FALSE.
