elisp: Warning Options

 
 37.5.3 Warning Options
 ----------------------
 
 These variables are used by users to control what happens when a Lisp
 program reports a warning.
 
  -- User Option: warning-minimum-level
      This user option specifies the minimum severity level that should
      be shown immediately to the user.  The default is ‘:warning’, which
      means to immediately display all warnings except ‘:debug’ warnings.
 
  -- User Option: warning-minimum-log-level
      This user option specifies the minimum severity level that should
      be logged in the warnings buffer.  The default is ‘:warning’, which
      means to log all warnings except ‘:debug’ warnings.
 
  -- User Option: warning-suppress-types
      This list specifies which warning types should not be displayed
      immediately for the user.  Each element of the list should be a
      list of symbols.  If its elements match the first elements in a
      warning type, then that warning is not displayed immediately.
 
  -- User Option: warning-suppress-log-types
      This list specifies which warning types should not be logged in the
      warnings buffer.  Each element of the list should be a list of
      symbols.  If it matches the first few elements in a warning type,
      then that warning is not logged.
