emacs-flycheck 31-1.0006a59 On-the-fly syntax checking
This package provides on-the-fly syntax checking for GNU Emacs. It is a replacement for the older Flymake extension which is part of GNU Emacs, with many improvements and additional features.
Flycheck provides fully-automatic, fail-safe, on-the-fly background syntax checking for over 30 programming and markup languages with more than 70 different tools. It highlights errors and warnings inline in the buffer, and provides an optional IDE-like error list.
