My Emacs Package of the Week: CRUX

Some packages get mentioned over and over on different blogs and other Emacs related platforms. And other packages do not seem to get the same degree of attention (or at least I don’t see it) although they deserve it. IMO one of these is CRUX, which is most fittingly described as “a Collection of Ridiculously Useful eXtensions for Emacs” by its created, Bozhidar Batsov. It does provide a large collection of helper functions that may assist you in all kinds of situations of your Emacs life. I think I stumbled upon the package when reading an Emacs configuration file of some other fanatic and added it to my configuration after some inspection. And I have not regretted it ever since!

As with the functionality of Emacs itself I also only use a very small subset of the commands that CRUX provides. There are currently only five functions that I actively use (or intend to do so) out of the 32 ones that are currently provided. So I won’t go into full detail above all of them but only shortly cover the ones that sweeten my daily use.

The funny thing is that the functions defined in crux.el are neither that large (or use many helper functions themselves) nor very complex. It would be quite easy to implement most stuff on your own and it would certainly provide a great opportunity for learning a bit of Emacs Lisp (and Emacs). And I’m sure many have implemented at least some functions on their own. While I must admit that from time to time I’m tempted to do the same I am really grateful that this awesome package exists so that I can focus on other things.

If you have not heard, looked or tried CRUX for yourself then I can only recommend it and I encourage you to take a look and see what it can provide for you.
