研究方向
Start by examining Black's current parser implementation, likely in the 'blib2to3' directory, to understand how Python syntax is defined and parsed. Study the Cython language specification, particularly the syntax differences from Python (e.g., cdef, cpdef, extern). The goal is to extend Black's grammar to accept .pyx, .pxd, .pxi files. Check existing issues and PRs for prior attempts or discussions. No linked PRs exist, so this is a fresh implementation task.
