pdfdol

Data Object Layer for PDF data

To install: pip install pdfdol

Examples

Get a dict-like object to list and read the pdfs of a folder, as text:

>>> from pdfdol import PdfFilesReader
>>> from pdfdol.tests import get_test_pdf_folder
>>> folder_path = get_test_pdf_folder()
>>> pdfs = PdfFilesReader(folder_path)
>>> sorted(pdfs)
['sample_pdf_1', 'sample_pdf_2']
>>> assert pdfs['sample_pdf_2'] == [
...     'Page 1\nThis is a sample text for testing Python PDF tools.'
... ]

See that the values of a PdfFilesReader are lists of pages. If you need strings (i.e. all the pages together) you can add a decoder like so:

from dol import add_decoder
page_separator = '---------------------'
pdfs = add_decoder(pdfs, decoder=page_separator.join)

If you need this at the level of the class, just do this:

from dol import add_decoder
page_separator = '---------------------'
FilesReader = add_decoder(PdfFilesReader, decoder=page_separator.join)
# and then
pdfs = FilesReader(folder_path)
# ...

If you need to concatinate a bunch of pdfs together, you can do so in many ways. Here's one:

from dol import Files
from pdfdol import concat_pdfs

s = Files('~/Downloads/cosmograph_documentation_pdfs/')
concat_pdfs(s, key_order=sorted)
