Code Style Guide For Archivematica
Archivematica follows common Python coding standards, linked below. We encourage installing a Python linter to help with this. flake8 is recommended because it wraps three common linters (pep8, pyflakes, mccabe).
- PEP8 for styling
- Exception is line length, which should be wrapped at 79 characters or left long for the IDE to wrap.
- Imports are sorted alphabetically within their grouping to reduce duplicate imports
- PEP257 for docstring structure
- Parameters and return values should be specified in Sphinx-style.
- See also this pull request and associated discussion.
Example docstrings with Sphinx markup below. Other attributes that can be used in a docstring can be found on the Sphinx website.
def get_unit_status(unit_uuid, unit_type): """ Get status for a SIP or Transfer. Returns a dict with status info. Keys will always include 'status' and 'microservice', and may include 'sip_uuid'. Status is one of FAILED, REJECTED, USER_INPUT, COMPLETE or PROCESSING. Microservice is the name of the current microservice. SIP UUID is populated only if the unit_type was unitTransfer and status is COMPLETE. Otherwise, it is None. :param str unit_uuid: UUID of the SIP or Transfer :param str unit_type: unitSIP or unitTransfer :return: Dict with status info. """
def each_child(path, file_group_identifier, base_path, base_path_name, sip_uuid): """ Iterates over entries in a filesystem, beginning at `path`. At each entry in the filesystem, yields either a File model instance (for files) or a string (for directories). When iterating, makes two passes: first iterating over files, then directories. Does not iterate over directories; consumers should call this function again on directory strings to recurse. :param string path: path to a directory on disk to recurse into. :raises ValueError: if the specified path does not exist, or is not a directory. """
The file structure in Archivematica will comply with the Filesystem Hierarchy Standard (FHS).
