Export HTML links

[juanjosegarciaripoll]

When exporting org-mode files to HTML, it would be nice if we could export the ebib links as links to actual papers or to the webpages of those papers. I have cooked this option as an :around advice for org-html-link, the function that exports links. Is there a better solution? Could this be part of ebib?

(defun jjgr-ebib-export-link-as-doi (orig-fun link desc info)
  (let ((output nil))
    (when (string= (org-element-property :type link) "ebib")
      (let ((path (org-element-property :path link)))
        (save-match-data
          (string-match "^\\(.*?\\)\\(?:@\\(.*?\\)\\)?$" path)
          (let* ((key (match-string 1 path))
                 (db-name (match-string 2 path))
                 (db (if db-name
                         (ebib--load-bibtex-file-internal
                          (ebib--locate-bibfile
                           db-name
                           (append ebib-bib-search-dirs
                                   (list default-directory))))
                       (ebib--find-db-for-key key ebib--cur-db))))
            (when db
              (let* ((urls (ebib-get-field-value
                            ebib-url-field key db 'noerror 'unbraced 'xref))
                     (url (and urls (car (ebib--split-urls urls)))))
                (when url
                  (setq output (format "<a href=\"%s\">%s</a>"
                                       url
                                       (or desc (format "[%s]" key)))))))))))
    (if output
        output
      (funcall orig-fun link desc info))))

That would definitely be nice. :smiley:

There is a better solution, in fact, there's a canonical solution. When defining the link with org-link-set-parameters (which happens in org-ebib.el), there should be an :export property that tells Org which function to use for exporting the link.

There's an example of such an :export function in the Org manual here. If you feel up to it, feel free to create a PR. Otherwise, I'll try and find some time in the coming weeks.
