Change inspection severity
Inspection severity levels indicate how seriously the detected code problems affect your project. Every severity level has its own highlighting style. In RubyMine, there is a set of predefined severity levels:
Error: marks syntax errors.
Warning: marks code fragments that might produce bugs or require enhancement.
Weak Warning: marks code fragments that can be improved or optimized (redundant code, duplicated code fragments, and so on).
Server Problem: marks problems that come from an external build server, for example, from TeamCity.
Typo: marks spelling and grammar mistakes.No highlighting, only fix: provides no code highlighting; the list of available fixes is invoked by pressing Alt+Enter.
Severity levels are designed to indicate problems, they don't have any impact on the code execution: if you change the severity for spelling mistakes from Typo to Error, this won't affect the execution of your application.
