pdf-tools integration

Search contents of PDFs

If you run this and select candidates, this will pass the list of any associated PDF files to pdf-tools to search across all of them.

(defun ex/search-pdf-contents (keys-entries &optional string)
  "Search pdfs."
  (interactive (list (citar-select-refs)))
  (let ((files (seq-filter
                (lambda (file) (string-match-p "\\.pdf$" file))
                (citar-file--files-for-multiple-entries
                 (citar--ensure-entries keys-entries)
                 citar-library-paths
                 '("pdf"))))
        (string (or string (read-string "Search string: "))))
    (pdf-occur-search files string t)))

;; with this, you can exploit embark's multitarget actions, so that you can run `embark-act-all`
