This is a desired feature.

To be checked: Is this already covered by handling all shapes in all slides, or do we need to handle shapes on the slide master separately?

There is os.PathLike (https://docs.python.org/3/library/os.html#os.PathLike). Can we use this for type information instead of defining our own _Pathlike = Union[str, pathlib.Path]?

Apart from replacing a placeholder with a table, a valid use case is layouting a table in the template and only populating the fields with values.

This needs a bit of design consideration. Typical usecases:
a) replace all fields, including row/column headers
b) keep row/column headers and replace only the other fields.

Can this be handled sufficiently good in ´python-pptx? If so, should we just expose the underlying Presentation` object?

Add a method to Template:

def save_pdf(self, filename):
~~

Since `python-pptx` does not provide this capability. We need to rely on external programs (LibreOffice and/or PowerPoint).

LibreOffice can be used on the command line with

libreoffice --headless --convert-to pdf --outdir . filename.pptx

Tasks:
1. Check if LibreOffice is available on the system, if not fail
2. Create a temporary directory and save the tempate there as ´pptx`.
3. Run the above command in the temporary directory and target the output dir the user wants.
4. Cleanup

Optional:
Extend this to work with PowerPoint as well. Way of interaction with PowerPoint to be defined. I don't know if it can be controlled via command line.

Using text labels as placeholder is convenient for creation by the user. However, on the downside, the placeholder information vanishes once it is replaced.

• Upon opening a Template, parse all shapes for placeholders.
• For each placeholder shape update it's name attribute with the placeholder ID
• From then on, only use the name attribute as ID.
