There were two problems with the recently merged internal logging improvements:
print_yellow()was only called when warning but it is also used for informational prints.Simplify the regex by avoiding brackets and just using a simple
ERROR:andWARNING:prefix to the message.Introduce new logging functions:
die()to print a message and exit with error code 1,warn()to print a warning, andinfo()to print information. Use these consistently throughout the scripts. Adjust certain messages so that they will be caught by the new problem matcher.
