Using mkpdfs-mkdocs 1.0.1 Using mkdocs 1.0.4 Using python 3.8.1

When trying to use mkpdfs-mkdocs on our project, i've encoutered an exception :

ERROR   -  Error building page '[...]Release 250.md': list index out of range

    id = str.split(ext, '#')[1]
IndexError: list index out of range

After a little code hacking i've managed to identify the issue seems to happens on this type of links in our markdown :

# [More…](./#!/62GettingValues#meta-and-internalmeta)

I've managed to bypass the problem by patching preprocessor\links\transform.py like this :

    elif num_hashtags is 1:
        section, ext = tuple(os.path.splitext(tail))
        id = str.split(ext, '#')[1]

to :

    elif num_hashtags == 1:
        section, ext = tuple(os.path.splitext(tail))
        id = str.split(ext if len(ext) > 0 else section, '#')[1]

Hope this helps

Hi @thegrima;

Thanks for your report and the provided fix. I'll manage to insert this fix in the upcoming release as soon as I have few time to work on the project.

I had the same issue, @thegrima thank you for solving. And ofc @comwes thank you for building this, it saved me so much work. I had school project documented via mkdocs, but they wanted the documentation in pdf in the final submission. 40 pages, you are a savior
