带有 iso-8859-1 (latin1) 字符的 Cookiecutter 模板

Cookiecutter template with iso-8859-1 (latin1) characters

我正在为主要使用 utf-8 编码的 Python 项目创建自己的 cookiecutter template。但它包含以 iso-8859-1 (latin1) 编码的 .ini.php 文件。此资源必须以 latin1 编码,因为它是遗留代码的一部分。

当我运行:

cookiecutter cookiecutter-mytemplate  # <- directory of my project

我在代码生成过程中遇到以下错误:

Traceback (most recent call last):
  ...

    source, filename, uptodate = self.get_source(environment, name)

    contents = f.read().decode(self.encoding)
  File ".../lib/python2.7/encodings/utf_8.py", line 16, in decode
    return codecs.utf_8_decode(input, errors, True)
UnicodeDecodeError: 'utf8' codec can't decode byte 0xe9 in position 308: invalid continuation byte

当然,结果是部分生成的,在解析iso-8859-1文件(里面有一个“é”)时被打断了。

我可以使用 pre-/post- 钩子在模板生成之前将我的资源转换为 utf-8,然后再将它们转换回 iso-8859-1 吗?以及如何?

有没有办法处理非 utf-8 文件?

最后,我将所有 .ini.php 文件存储在 utf-8 中,并使用钩子将文件转换为 post 代中的 iso-8859-1。

这里是hooks/post_gen_project.py的代码:

# coding: utf-8
from __future__ import print_function, unicode_literals

import io
import os


def convert_resources(src_dir):
    if "src" in os.listdir(src_dir):
        src_dir = os.path.join(src_dir, "src")
    print("src_dir: " + src_dir)

    for root_dir, dirnames, filenames in os.walk(src_dir):
        for filename in filenames:
            ext = os.path.splitext(filename)[1]
            if ext in ('.ini', '.php'):
                src_path = os.path.join(root_dir, filename)
                print("  Converting '{relpath}'...".format(relpath=os.path.relpath(src_path, src_dir)))
                with io.open(src_path, mode="r", encoding="utf-8") as fd:
                    content = fd.read()
                with io.open(src_path, mode="w", encoding="iso-8859-1") as fd:
                    fd.write(content)


if __name__ == '__main__':
    convert_resources(os.getcwd())
