Error occurs when twice renaming

[yuriever]

Hi! Thanks for this very useful tool!

I installed the following version:

pip install pdf-renamer==1.0rc9

and met the following three issues:

Error occurs when twice renaming

I tried rename the same pdf twice with different format

pdfrenamer 'test' -f '{YYYY}{MM} {T}, {A3etal}' -fr
pdfrenamer 'test' -f '{YYYY} {T}, {A3etal}' -fr 

and the second fails. The error messages are

Old arxiv-id is not recognized

When renaming old arxiv papers pdf2doi will try searching google. Unfortunately google is blocked here and this relates to pdf2doi/issues/16

Adding arxiv-id in the file name

Could you provide a tag of arxiv-id? I want to rename the pdfs like

{arxiv-id} {T}, {A3etal}

but find this is not supported in pdfrenamer/filename_creators.py

[yuriever]

The google search can be disabled by changing the default settings.ini of pdf2doi

websearch = False

Hey! Sorry it took me so long to answer this.

• Yes, adding the arxiv-id tag is a great idea, I will add it to the next version

• Yes, indeed you can disable the google search by tweaking the .ini file of pdf2doi. But this is a good point, I will try to add an option to be able to disable it directly from pdf-renamer

• Regarding the other error you mentioned, it looks like the first time you tried to rename the file, pdfrenamer found the bibtex info from export.arxiv.org, and it was able to correctly parse them. The second time, it instead used dx.doi.org to validate the DOI and get the bibtex info. For some reason, this time the raw bibtex info (from dx.doi.org) were not parsed correctly.
  I am gonna need to run some test, can you send me the pdf file?
  Also, which version of pdfrenamer are you using?

[yuriever]

Thanks for the reply.
The original file is 2208.14233 Top-down holography in an asymptotically flat spacetime, Kevin Costello.pdf, which can be found here.
The renamed file is
2208 Top-down holography in an asymptotically flat spacetime, Costello, Paquette, Sharma.pdf
The version is pdf-renamer==1.0rc9.

I also found another issue, but am not sure it's about pdf-renamer.
The original file before renaming has table of contents and hyperlinks to references (the former example doesn't have TOC, so I choose another pdf here.)
2201.01630v1 Chaos in Celestial CFT, Sabrina Pasterski.pdf
but after renaming and other operations (e.g. sync tools, being opened by other pdf reader.), the table of contents and hyperlinks are broken.
2208 Chaos in celestial CFT, Pasterski, Verlinde.pdf
You see the right original one has TOC, while the left does not.

I'm totally unfamiliar with the structure of pdfs. This issue may depend on my environment. Do you have any idea about this?
