The pdftotext package provides functions for extraction of plain text from PDF documents. It uses C++ library Poppler, which is required to be installed in the system. Output of Haskell pdftotext library is identical to output of Poppler's tool pdftotext.


import qualified Data.Text.IO as T
import Pdftotext

main :: IO ()
main = do
  Just pdf <- openFile "path/to/file.pdf"
  T.putStrLn $ pdftotext Physical pdf


pdftotext comes with executable program pdftotext.hs which can print text extracted from PDF and basic information from the document.

$> pdftotext.hs info test/simple.pdf
File      : test/simple.pdf
Pages     : 4
  Title   : Simple document for testing
  Author  : G. Eyaeb
  Subject : Testing
  Creator : pdflatex
  Producer: LaTeX with hyperref
  Keywords: haskell,pdf
$> pdftotext.hs text --pages 1,4 test/simple.pdf
Simple document for testing

                  deserve neither
liberty nor safety.

$> pdftotext.hs --help
$> pdftotext.hs text --help
$> pdftotext.hs info --help


The library uses poppler via FFI, therefore internally all functions are of type IO. However, their non-IO variants (using unsafePerformIO) should be safe to use. Module Pdftotext.Internal exposes all IO-typed functions.
