[Enhancement] Automatic version number

[the01]

I would like to propose a way to automatically load the version info from the package (init.py) into setup.py:

def get_version():
    import os
    import re
    init_file = os.path.join("html2text", "__init__.py")
    init_lines = open(init_file, 'rt').readlines()
    version_re = r"^__version__ = ['\"]([^'\"]*)['\"]"
    for line in init_lines:
        mo = re.search(version_re, line, re.M)
        if mo:
            return mo.group(1)
    raise RuntimeError(u"Unable to find version string in {}".format(init_file))

and then you just do

setup(
    name="html2text",
    version=get_version(),
    ...
)

Good idea, I do this in other projects that I maintain.

• https://github.com/Alir3z4/python-short_url/blob/master/setup.py#L8
• https://github.com/Alir3z4/python-short_url/blob/master/short_url/__init__.py#L50

lemme know what you think about it ;)

Using import() with .version is certainly cleaner, but the problem is that you actually import that file, meaning you are running code here. Say if you had some further imports in the init-file, those would get imported too and so on and so on. You might end up with race conditions or difficulties with relative imports...
That's why I went for the more inelegant version of parsing the file line by line while applying a regex.
Well, my 2 cents on the topic..
