Python 3.10 issue (Collections), CairoSVG Issue, DeleteFirstSlide directive

[McQuitty-Broadcom]

Martin,

In python 3.10, we have to import the collections prior to importing Presentation.

This address that.

Also, there's a bug introduced in this version. I moved the import cairo helpers into the try block. Mine was failing.

I also added a new "deletefirstslide" global directive. If the directive is set, it will delete the first slide. It's in a try block, as the helper fails if it is not set. If it fails, the except block just passes the normal save operation.

[MartinPacker]

Thanks for this!

2 questions:

1. How do you get over python-pptx having a problem with 3.10?
2. How do you do the actual delete of the first slide?

I'm finishing something up that I hope will enable the merge.

[MartinPacker]

I've merged and pulled down onto my machine. I can't test 3.10 support yet.

But I will test deletefirstslide first.

Then I'll need to update the docs.

Please don't change the code until I push the code again or else signal you can. Thanks!

[McQuitty-Broadcom]

Not sure why the collections issue is there with python-pptx. But say this as a solution. It shouldn't affect other versions.

As for deleting the first slide, there's two parts. A directive at the top. SectionSlideLayout: 4 TitleOnlyLayout: 17 BlankLayout: 11 ContentSlideLayout: 11 DeleteFirstSlide: true

If that's there, there's a section of code that loops through to delete the slide. It uses the del function on the slide. Now that I think about it, it might impact your slide numbering. I don't use that feature, so I didn't think of it until now. If that's the case, the slide counting might need to be adjusted.

Ok, no worries. I had some free time so I pushed that in. But I'll wait for any other changes.

[MartinPacker]

I'm having to work on the deletefirstslide code a bit...

Syntax will be:

deleteFirstSlide: yes

for consistency.

[MartinPacker]

OK. Just pushed a "fiddled with" :-) version that works with the above syntax. The default will be no , by the way.

pls pull this version.

Will be documenting tonight - alongside the documentation for https://github.com/MartinPacker/md2pptx/pull/111.

Then I can release v2.6.

Thanks for your help!

[McQuitty-Broadcom]

Of course. Thank you for putting this out there.

When you get to Dallas, we can talk about how I use it as part of a pipeline. And I have something for you to take back.

Are you a pint or tea guy? Or both?

It would be greedy to say "both". But tea works better for me in terms of kitchen real estate. :-)

Looking forward to meeting you.

BTW I'm going to move the code to delete a slide into a function. In case @scanny gives us official support. And thanks to @chipset.

[McQuitty-Broadcom]

Ok. Thanks for letting me know about the tea/pint issue.

And yes, it would be nice to have official support.

So all that's left to do before I close this is document DeleteFirstSlide.

[MartinPacker]

Docs pushed.
