[ENH] - Add support for .ppt / .pptx

[nenb]

Feature description

(Largely a copy/paste from #225)

Powerpoint documents are everywhere in the corporate world. We should support them out of the box. There are multiple Python packages out there that provide this functionality. We should do a light comparison of them to get a clearer picture. Optimally, we find a package that can give us page information. Not sure if that is possible in these data formats though.

Value and/or benefit

Users with corporate documents will have a lower barrier of entry.

Anything else?

Hi!

I'd like to take this challenge as my first issue!

I have looked into issue #225 and #221 and I think the feature can be achieved using the library python-pptx which has similar API to python-docx, already used for #221

I've installed Ragna and looked at the codebase, but currently I can only work with RagnaDemo, as I don't have a vector DB or an API key for a LLM, but I think as long as we correctly define a DocumentHandler implementing

• requirements(cls) -> list[Requirement]:
• supported_suffixes(cls) -> list[str]
• extract_pages(self, document: Document) -> Iterator[Page]

we should be fine, right? Of course I'll add testing and documentation.

Let me know if I can be assigned to this issue. Thanks!

Hey Davide and welcome to Ragna 👋 Sure go ahead!

You can install local Vector DBS, i.e. Chroma and LanceDB. Either do it manually, pip install

ragna/pyproject.toml

Lines 58 to 59 in 61e8d5f

	"chromadb>=0.4.13",
	"lancedb>=0.2",

or simply use the catch-all key pip install -e '.[all]'.

But yes, without an LLM API key, there is only the demo assistant for now.

Yes, that is sufficient. You can implement and test the document handler without having access to everything else.
