Glibc确实支持具有显式状态的语言环境API。这是使用ctypes制作的API的快速包装。
# -*- coding: utf-8import ctypesclass Locale(object): def __init__(self, locale): LC_ALL_MASK = 8127 # LC_COLLATE_MASK = 8 self.libc = ctypes.CDLL("libc.so.6") self.ctx = self.libc.newlocale(LC_ALL_MASK, locale, 0) def strxfrm(self, src, iteration=1): size = 3 * iteration * len(src) dest = ctypes.create_string_buffer(' 00' * size) n = self.libc.strxfrm_l(dest, src, size, self.ctx) if n < size: return dest.value elif iteration<=4: return self.strxfrm(src, iteration+1) else: raise Exception('max number of iterations trying to increase dest reached') def __del__(self): self.libc.freelocale(self.ctx)和简短的测试
locale1 = Locale('C')locale2 = Locale('mk_MK.UTF-8')a_list = ['а', 'б', 'в', 'ј', 'ќ', 'џ', 'ш']import randomrandom.shuffle(a_list)assert sorted(a_list, key=locale1.strxfrm) == ['а', 'б', 'в', 'ш', 'ј', 'ќ', 'џ']assert sorted(a_list, key=locale2.strxfrm) == ['а', 'б', 'в', 'ј', 'ќ', 'џ', 'ш']剩下要做的就是实现所有语言环境功能，支持python unipre字符串（我猜是wchar *函数），并自动导入包含文件定义或其他内容
