Error message stated:"So I think I found a bug with mo.pdf . I can't seem to get mo.pdf to open a local pdf. It works with the src as a url, but not from a file."

Haleshot · Answer

The issue is you would need to have the mo.pdf(src=pdf_file) assigned to a variable which you state at the end of the cell block for it to be rendered as the output.

Haleshot · Answer

This is the case with conditional statements in general. For example:actual = None
with open("2104.00282v4.pdf", "rb") as file: actual = mo.pdf(src=file)
actual

You can see the working solution for your issue here: https://marimo.app/l/6qpvveJust upload the PDF from the top left "View Files" explorer section and the above notebook should work.

Ok, yeah that makes sense. The documentation example is a bit misleading since it doesn't assign Mo.pdf to a variable that can be placed at the end of the cell.

The with open block doesn't return anything, the documentation should probably be updated to reflect that

Ah, thanks for that.

We can use Path to avoid the with block

yeah, I guess I should have said I found a bug in the documentation. but, did learn with blocks return nothing (null?)...
