cattrs is an open source Python library for structuring and unstructuring data.
cattrs works best with attrs classes, dataclasses and the usual Python
collections, but other kinds of classes are supported by manually registering
converters.
Python has a rich set of powerful, easy to use, built-in data types like
dictionaries, lists and tuples. These data types are also the lingua franca of
most data serialization libraries, for formats like json, msgpack, yaml or toml.
Data types like this, and mappings like dict s in particular, represent
unstructured data. Your data is, in all likelihood, structured: not all
combinations of field names or values are valid inputs to your programs. In
Python, structured data is better represented with classes and enumerations.
attrs is an excellent library for declaratively describing the structure of your
data, and validating it.
When you're handed unstructured data (by your network, file system,
database...), cattrs helps to convert this data into structured data. When you
have to convert your structured data into data types other libraries can handle,
cattrs turns your classes and enumerations into dictionaries, integers and
strings.
NOTE: If this package has multiple flavors (see below), then use one of them instead of the name specified above. NOTE: This is a Python port. Instead of py312-cattrs listed in the above command, you can pick from the names under the Packages section.
===> The following configuration options are available for py312-cattrs-26.2.0:
CBOR2=off: cobr2 serialization support
MSGPACK=off: msgpack serialization support
MSGSPEC=off: msgspec serialization support
ORJSON=off: orjson serialization support
PYYAML=off: PyYAML serialization support
TOMLKIT=off: tomlkit serialization support
TOMLLIB=off: tomli/tomli-w serialization support
UJSON=off: UltraJSON serialization support
===> Use 'make config' to modify these settings

Mk/Uses/python.mk: Introduce PY_EXCEPTIONGROUP
The minimal version is set to 1.1.1 because it is required by devel/py-cattrs.
Convert ports to use PY_EXCEPTIONGROUP to simplify Makefile.
With hat: python
all: remove explicit versions in USES=python for "3.x+"
The logic in USES=python will automatically convert this to 3.8+ by
itself.
Adjust two ports that only had Python 3.7 mentioned but build fine
on Python 3.8 too.

Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.
Approved by: portmgr (tcberner)
Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.
