I have played with a lot of options to give org-mode links extra functionality. Here are a few of the ideas I have looked at so far.
- Enabling right clicks on links
- A home made minibuffer menu in org-ref
- A helm buffer in org-ref
Here, I want to explore a hydra menu for a link. The idea is pretty simple, we need functions that do something with the link at point, and a hydra interface to call them. This turned out to be a little tricky. I could not get the path from the link in the link lambda function, and we need a way to pass the path to the function. I use a global variable for that. I wish there was another way to do that, but this does actually work. We illustrate it here with a more functional doi link.
(defun doi-crossref () "Search DOI in CrossRef." (interactive) (browse-url (format "http://search.crossref.org/?q=%s" *doi-hydra-path*))) (defun doi-google-scholar () "Google scholar the doi." (interactive) (browse-url (format "http://scholar.google.com/scholar?q=%s" *doi-hydra-path*))) (defun doi-pubmed () "Pubmed the doi." (interactive) (browse-url (format "http://www.ncbi.nlm.nih.gov/pubmed/?term=%s" (url-hexify-string *doi-hydra-path*)))) (defhydra doi-hydra () "org-ref" ("c" doi-crossref "Crossref") ("g" doi-google-scholar "Google Scholar") ("p" doi-pubmed "Pubmed")) (org-add-link-type "doi" (lambda (path) (setq *doi-hydra-path* path) (doi-hydra/body)))
|lambda||(path)||(setq doi-hydra-path path)||(doi-hydra/body)|
Now for a test, 10.1021/jp047349j.
It works fine, when you click on a link, you get a minibuffer menu with context hints, and pressing any other key than is defined simply cancels the command.
