Removed Google Plus.
Add a second, earlier hook, useful for altering data such as the body which is then used by all buttons.
Revert changes in previous version: again correctly return a string from theme function; reposition alter hook.
* Improve usefulness of new hook_socbutt_buttons_alter(). * Don't render markup too soon.
Incorporated patch from https://www.drupal.org/node/2671020 by Renrhaf which:
* converts markup production to use Drupal's theme layer * adds a drupal_alter() hook to allow other modules to alter the buttons * adds a LinkedIn share * does a general code cleanup and fixes possible minor PHP warnings
Removed unnecessary 'type' key from Socbutt token definition. This could cause a white screen under specific circumstances.
Fixed PHP warning after migrating from 1.0.
* block IDs were renamed to avoid name redundancy * now produces cleaner markup
Initial release.
