Added reportPrivateImportUsage diagnostic rule, which reports usage of a symbol from a py.typed library that is not intended to be re-exported by the library's author. The rule is on by default in basic type checking mode but can be disabled. Completion provider no longer offers these symbols as completion suggestions.

|
||||
|
||||
**reportPrivateUsage** [boolean or string, optional]: Generate or suppress diagnostics for incorrect usage of private or protected variables or functions. Protected class members begin with a single underscore (“_”) and can be accessed only by subclasses. Private class members begin with a double underscore but do not end in a double underscore and can be accessed only within the declaring class. Variables and functions declared outside of a class are considered private if their names start with either a single or double underscore, and they cannot be accessed outside of the declaring module. The default value for this setting is 'none'.
|
||||
|
||||
**reportPrivateImportUsage** [boolean or string, optional]: Generate or suppress diagnostics for use of a symbol from a "py.typed" module that is not meant to be exported from that module. The default value for this setting is 'error'.
|
||||
|
||||
**reportConstantRedefinition** [boolean or string, optional]: Generate or suppress diagnostics for attempts to redefine variables whose names are all-caps with underscores and numerals. The default value for this setting is 'none'.
|
||||
|
||||
**reportIncompatibleMethodOverride** [boolean or string, optional]: Generate or suppress diagnostics for methods that override a method of the same name in a base class in an incompatible manner (wrong number of parameters, incompatible parameter types, or incompatible return type). The default value for this setting is 'none'.
