t.p.deprecate : module documentation

Part of twisted.python View Source

Deprecation framework for Twisted.

To mark a method or function as being deprecated do this:
   def badAPI(self, first, second):
       '''
       Docstring for badAPI.
       '''
       ...
   badAPI = deprecate(Version("Twisted", 8, 0, 0))(badAPI)

The newly-decorated badAPI will issue a warning when called. It will also have a deprecation notice appended to its docstring.

To mark module-level attributes as being deprecated you can use:
   badAttribute = "someValue"

   ...

   deprecatedModuleAttribute(
       Version("Twisted", 8, 0, 0),
       "Use goodAttribute instead.",
       "your.full.module.name",
       "badAttribute")

The deprecated attributes will issue a warning whenever they are accessed. If the attributes being deprecated are in the same module as the deprecatedModuleAttribute call is being made from, the __name__ global can be used as the moduleName parameter.

See also Version.
VariablesDEPRECATION_WARNING_FORMATThe default deprecation warning string format to use when one is not provided by the user. (type: str )
Function getWarningMethod Return the warning method currently used to record deprecation warnings.
Function setWarningMethod Set the warning method to use to record deprecation warnings.
Function getDeprecationWarningString Return a string indicating that the callable was deprecated in the given version.
Function deprecated Return a decorator that marks callables as deprecated.
Function deprecatedModuleAttribute Declare a module-level attribute as being deprecated.
Function _getDeprecationDocstring Undocumented
Function _getDeprecationWarningString Return a string indicating that the Python name was deprecated in the given version.
Function _appendToDocstring Append the given text to the docstring of thingWithDoc.
Class _ModuleProxy Python module wrapper to hook module-level attribute access.
Class _DeprecatedAttribute Wrapper for deprecated attributes.
Function _deprecateAttribute Mark a module-level attribute as being deprecated.
def getWarningMethod(): (source)
Return the warning method currently used to record deprecation warnings.
def setWarningMethod(newMethod): (source)

Set the warning method to use to record deprecation warnings.

The callable should take message, category and stacklevel. The return value is ignored.
def _getDeprecationDocstring(version): (source)
Undocumented
def _getDeprecationWarningString(fqpn, version, format=None): (source)
Return a string indicating that the Python name was deprecated in the given version.
ParametersfqpnFully qualified Python name of the thing being deprecated (type: str )
versionVersion that fqpn was deprecated in (type: twisted.python.versions.Version )
formatA user-provided format to interpolate warning values into, or DEPRECATION_WARNING_FORMAT if None is given (type: str )
ReturnsA textual description of the deprecation (type: str )
def getDeprecationWarningString(callableThing, version, format=None): (source)
Return a string indicating that the callable was deprecated in the given version.
ParameterscallableThingCallable object to be deprecated (type: callable )
versionVersion that fqpn was deprecated in (type: twisted.python.versions.Version )
formatA user-provided format to interpolate warning values into, or DEPRECATION_WARNING_FORMAT if None is given (type: str )
ReturnsA textual description of the deprecation (type: str )
def deprecated(version): (source)
Return a decorator that marks callables as deprecated.
ParametersversionThe version in which the callable will be marked as having been deprecated. The decorated function will be annotated with this version, having it set as its deprecatedVersion attribute. (type: twisted.python.versions.Version )
def _appendToDocstring(thingWithDoc, textToAppend): (source)

Append the given text to the docstring of thingWithDoc.

If thingWithDoc has no docstring, then the text just replaces the docstring. If it has a single-line docstring then it appends a blank line and the message text. If it has a multi-line docstring, then in appends a blank line a the message text, and also does the indentation correctly.
def _deprecateAttribute(proxy, name, version, message): (source)
Mark a module-level attribute as being deprecated.
ParametersproxyThe module proxy instance proxying the deprecated attributes (type: _ModuleProxy )
nameAttribute name (type: str )
versionVersion that the attribute was deprecated in (type: twisted.python.versions.Version )
messageDeprecation message (type: str )
def deprecatedModuleAttribute(version, message, moduleName, name): (source)
Declare a module-level attribute as being deprecated.
ParametersversionVersion that the attribute was deprecated in (type: twisted.python.versions.Version )
messageDeprecation message (type: str )
moduleNameFully-qualified Python name of the module containing the deprecated attribute; if called from the same module as the attributes are being deprecated in, using the __name__ global can be helpful (type: str )
nameAttribute name to deprecate (type: str )
