flycheck-popup-tip
is now available on Melpa. It took too long to get there doe to lack of free time recently…
flycheck-popup-tip is extension for Flycheck. It implements minor-mode for displaying errors from Flycheck using popup.el. Repo placement is under Flycheck org.
There is another official flycheck-pos-tip extension for displaying errors under point. However, it does not display popup if you run Emacs under TTY (where I use GNU Emacs). Also, It displays message on echo area and that is often used for help texts from ELDoc.
