README

        
* Documentation

~pdf-drop-mode~ is a convenient mode that search for the [[https://en.wikipedia.org/wiki/Digital_object_identifier][DOI]] of any file that is

dropped onto a buffer. To do that, the mode searches the DOI using several

different methods (whose order can be specified):

1. Look at the file metadata to check if a DOI is attached using exiftool

   (whose path can be specified).

2. Search the content of the file to try to locate a DOI regex on the first

   page (PDF is transformed into text  using the pdftotext utility).

3. Search again the metadata to try to find the title and query the crossref

   database to get a corresponding DOI.

4. Ask the user to enter the title of the file and query the crossref database

   to try to get a correspondong DOI.

If all methods failed, then the search has failed. When search finishes, a user-defined function is called with the filename and

the DOI as arguments.

** Installation

#+begin_src emacs-lisp

(straight-use-package

 '(pdf-drop-mode :type git :host github :repo "rougier/pdf-drop-mode"))

#+end_src

* Usage

#+begin_src emacs-lisp

(require 'pdf-drop-mode)

(defun my/pdf-process (file doi)

  (message "%s : %s" file doi))

(setq pdf-drop-search-hook #'my/pdf-process)

(pdf-drop-mode)

#+end_src

You can then drag and drop a PDF onto the buffer and the DOI should be displayed.
