From 9ecb2808f1bd293ef76a1d60905f0d029fd2236f Mon Sep 17 00:00:00 2001 From: Tikhon Jelvis Date: Tue, 17 Oct 2023 12:32:00 -0700 Subject: [PATCH] Add dependency on native Tesseract OCR executable for pytesseract MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The pytesseract package needs to have the `tesseract` executable available at runtime to work. By default, the Python package looks for the `tesseract` executable in the PATH. This doesn't work here, so we need to override the `tesseract_cmd` with the path to the `tesseract` executable we pulled in from Nix. I did this with a patch [based on how pytesseract is set up in Nixpkgs][1]. The patching code feels a bit fiddly. I don't know the idiomatic way to do this sort of thing. I included a test that will fail if pytesseract cannot find the `tesseract` executable. The test passed for me with both `preferWheels = true` and `preferWheels = false`, but I only included one in the test suite here, not sure if it makes sense to have both—the actual patching code had to be a bit different depending on whether the source was a wheel or not.
