Bug 2325168

python-colorful fails to build with Python 3.14.0a1.

The issue comes from the usage of the removed ast.Constant.s property.
The relevant line: https://github.com/timofurrer/colorful/blob/v0.5.5/setup.py#L43


https://docs.python.org/3.14/whatsnew/3.14.html:
ast

    Remove the following classes. They were all deprecated since Python 3.8, and have emitted deprecation warnings since Python 3.12:
        ast.Bytes
        ast.Ellipsis
        ast.NameConstant
        ast.Num
        ast.Str

    Use ast.Constant instead. As a consequence of these removals, user-defined visit_Num, visit_Str, visit_Bytes, visit_NameConstant and visit_Ellipsis methods on custom ast.NodeVisitor subclasses will no longer be called when the NodeVisitor subclass is visiting an AST. Define a visit_Constant method instead.
    Also, remove the following deprecated properties on ast.Constant, which were present for compatibility with the now-removed AST classes:
        ast.Constant.n
        ast.Constant.s
    Use ast.Constant.value instead.

Testing and mass rebuild of packages is happening in copr.
You can follow these instructions to test locally in mock if your package builds with Python 3.14:
https://copr.fedorainfracloud.org/coprs/g/python/python3.14/

Let us know here if you have any questions.

Python 3.14 is planned to be included in Fedora 43.
To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.14.
A build failure prevents us from testing all dependent packages (transitive [Build]Requires),
so if this package is required a lot, it's important for us to get it fixed soon.

We'd appreciate help from the people who know this package best,
but if you don't want to work on this now, let us know so we can try to work around it on our side.
