[docs]classParsedMessageResult(NamedTuple):""" A read-only named tuple object representing the result from parsing a commit message. Essentially this is a data structure which holds the parsed information from a commit message without the actual commit object itself. Very helpful for unit testing. Most of the fields will replicate the fields of a :py:class:`ParsedCommit <semantic_release.commit_parser.token.ParsedCommit>` """bump:LevelBumptype:strcategory:strscope:strdescriptions:tuple[str,...]breaking_descriptions:tuple[str,...]=()release_notices:tuple[str,...]=()linked_issues:tuple[str,...]=()linked_merge_request:str=""include_in_changelog:bool=True
[docs]classParsedCommit(NamedTuple):"""A read-only named tuple object representing the result of parsing a commit message."""bump:LevelBump"""A LevelBump enum value indicating what type of change this commit introduces."""type:str""" The type of the commit as a string, per the commit message style. This is up to the parser to implement; for example, the EmojiCommitParser parser fills this field with the emoji representing the most significant change for the commit. """scope:str""" The scope, as a string, parsed from the commit. Generally an optional field based on the commit message style which means it very likely can be an empty string. Commit styles which do not have a meaningful concept of "scope" usually fill this field with an empty string. """descriptions:list[str]""" A list of paragraphs from the commit message. Paragraphs are generally delimited by a double-newline since git commit messages are sometimes manually wordwrapped with a single newline, but this is up to the parser to implement. """breaking_descriptions:list[str]""" A list of paragraphs which are deemed to identify and describe breaking changes by the parser. An example would be a paragraph which begins with the text ``BREAKING CHANGE:`` in the commit message but the parser gennerally strips the prefix and includes the rest of the paragraph in this list. """commit:Commit"""The original commit object (a class defined by GitPython) that was parsed"""release_notices:tuple[str,...]=()""" A tuple of release notices, which are additional information about the changes that affect the user. An example would be a paragraph which begins with the text ``NOTICE:`` in the commit message but the parser generally strips the prefix and includes the rest of the paragraph in this list. """linked_issues:tuple[str,...]=()""" A tuple of issue numbers as strings, if the commit is contains issue references. If there are no issue references, this should be an empty tuple. Although, we generally refer to them as "issue numbers", it generally should be a string to adhere to the prefixes used by the VCS (ex. ``#`` for GitHub, GitLab, etc.) or issue tracker (ex. JIRA uses ``AAA-###``). """linked_merge_request:str=""""" A pull request or merge request definition, if the commit is labeled with a pull/merge request number. This is a string value which includes any special character prefix used by the VCS (e.g. ``#`` for GitHub, ``!`` for GitLab). """include_in_changelog:bool=True""" A boolean value indicating whether this commit should be included in the changelog. This enables parsers to flag commits which are not user-facing or are otherwise not relevant to the changelog to be filtered out by PSR's internal algorithms. """@propertydefmessage(self)->str:""" A string representation of the commit message. This is a pass through property for convience to access the ``message`` attribute of the ``commit`` object. If the message is of type ``bytes`` then it will be decoded to a ``UTF-8`` string. """returnforce_str(self.commit.message).replace("\r","")@propertydefhexsha(self)->str:""" A hex representation of the hash value of the commit. This is a pass through property for convience to access the ``hexsha`` attribute of the ``commit``. """returnself.commit.hexsha@propertydefshort_hash(self)->str:"""A short representation of the hash value (in hex) of the commit."""returnself.hexsha[:7]@propertydeflinked_pull_request(self)->str:"""An alias to the linked_merge_request attribute."""returnself.linked_merge_request
