• goggles.el - Pulse modified region

#+html: #+html: #+html:

Goggles highlights the modified region using =pulse=. Currently the commands undo, yank, kill and delete are supported.

This library is the holy counterpart of =evil-goggles=. Another comparable library is =volatile-highlights=, which does not use =pulse=. By setting =goggle-pulse= to =nil=, the =goggles-mode= behaves similarily to the =volatile-highlights-mode=.

** Comparison to volatile-highlights

Goggles is mainly meant as a replacement for the popular volatile-highlights (vhl).

• vhl does not support pulse. The request to use pulse for modification highlighting has come up a few times (e.g. recently on reddit).
• vhl is unmaintained and contains obsolete code (e.g. cl instead of cl-lib).
• vhl is unnecessarily complicated, with its extension mechanism. The extension mechanism seems to require bytecode compilation at startup.

Since improving volatile-highlights would require a rewrite, I decided to create another package. This way breakage for volatile-highlights users is avoided.
