I tested part of this on Windows in a git bash shell: $ pdftotext -v pdftotext version 0.14.5 Copyright 2005-2010 The Poppler Developers - http://poppler.freedesktop.org Copyright 1996-2004 Glyph & Cog, LLC
and then this works: $ pdftotext.exe kitchin-2015-examp.pdf - | grep DOI ACS Catal., Just Accepted Manuscript • DOI: 10.1021/acscatal.5b00538 • Publicati on Date (Web): 11 May 2015 readers and citable by the Digital Object Identifier (DOI®). “Just Accepted” is an optional service offered sharing site which assigned the data set a DOI. 19 An alternative data repositor y could be an institutional data repository which also provides a DOI for citing. It remains t o be seen if stores that provide a citable DOI for the data set. The point is that this appro ach is very However, I see that in emacs, it appears another pdftotext is getting used, which does not work. ~/Desktop $ pdftotext -v pdftotext version 2.03 Copyright 1996-2003 Glyph & Cog, LLC that is the same version that runs in a cmd shell. The version that seems to work for me is at "C:\Program Files (x86)\Git\bin\pdftotext". I added a variable to set the location of this program, and then rely on the executable path. It was a little tricky to set this right, note the escaped quotes. #+BEGIN_SRC emacs-lisp (setq pdftotext-executable "\"C:/Program Files (x86)/Git/bin/pdftotext\"") #+END_SRC It turned out there was another issue with the uri in the drag-n-drop needing to be unescaped on windows because of the : in the path, which is also done now. I pushed these out. hopefully that makes some progress for you! or at least gives some hints on where to look for the problem. Merry Xmas!
