# Minimum build requirements tested in CI need to be kept in sync with the
# versions in requires below so that they are tested.
#
# To support the freethreaded build (CPython 3.14t) version 3.1.0 of Cython is
# needed as a minimum requirement. It is possible that future versions of
# Cython might still work but typically a Cython release breaks something in
# the build of python-flint so we include an upper bound here.
#
# Apart from the freethreading build any Cython version from 3.0.11 onwards is
# fine. It is not possible to have a separate version constraint here for the
# freethreading build only though.

# E129 visually indented line with same indent as next logical line

#            (see https://github.com/PyCQA/pycodestyle/issues/386)
#            and we ignore it to avoid needing additional indentation after
#            long logical statements.
#
# E501 line too long (128 > 120 characters)
# Reasoning: this is a work in progress and will be enforced once a line length
#            and refactor has taken place. See issue #214
#
# E741 ambiguous variable name
# Reasoning: many places it makes sense to use l or other letters as variable
#            names as it is standard in mathematical notation.
