added support for .docm files

[EmanueleCannizzaro]

A long lasting issue with python-docx has been the lack of support of macro-enabled files.
A patch has been created a long time ago but I was never merged in master branch.

It is identical approach as suggested in #673.

Instead of:
if document_part.content_type not in [CT.WML_DOCUMENT_MAIN, CT.WML_DOCUMENT_MACRO_ENABLED_MAIN]:

Why not:
if document_part.content_type not in {CT.WML_DOCUMENT_MAIN, CT.WML_DOCUMENT_MACRO_ENABLED_MAIN}:

I.e. change the collection type to a set. I feel that it's just better practice when all you want to do is test for membership.

This would be great if this pull request be accepted as it is super simple & will avoid all of us that need to load .docm files to do dirty setups either by modifying your library locally or overloading it.
Cheers.

I agree that it would be great if this gets merged, currently I use a script that uses soffice to convert .docm files to .docx, which takes some time for each document

@scanny Is there any blocking point preventing the acceptance of this pull request ? it seems to pass the checks.
I implemented the modifications locally & it is dirty but it works very well.
Is there something we can do to help it move it forward?
It might seem a detail for you but for people working with .docm files this is a really painful problem.
Cheers

Worked great for me when I implemented this patch on my own - able to work with docx and docm files without issue.

[DanielPekar-RJC]

Seems OK

Works very nice. Macros are preserved after saving, everything is fine.
Would be great having this finally integrated!

Please merge :(

Hello,

It seems like there are some forks of python-docx just for this purpose, including one called "python-docx-docm". Turns out it doesn't work either as you get an error:

AttributeError: 'Part' object has no attribute 'document'

Because one line is missing (the modification of init.py in this MR). It can be monkey patched on-the-fly in the code, with this line of code:

docx.opc.part.PartFactory.part_type_for[docx.opc.constants.CONTENT_TYPE.WML_DOCUMENT_MACRO_ENABLED_MAIN] = docx.parts.document.DocumentPart

With this modification, docm file can be opened with the "python-docx-docm" forks. But it would be best if this MR could be merged

Any news on this being implemented? Seems like an easy issue.

Why is this still not merged?
