How to get started to build your own Spacemacs	2018-10-12 12:59	emacs	Tools

I have been a Vim user for quite a while. I love it, so the very first thing when I set up a new server is installing VIM. I heard a lot about Emacs and tried it. It's better at almost everything except text editing. So I stayed with Vim until Spacemacs was released. The Vim key bindings of Spacemacs is so excellent that I switched.

However, Spacemacs has its problem: boots up slowly and crashes frequently. Upgrading packages became very challenging. Finally, I have to use the develop branch because the master branch is not working anymore. People began to complain and requested to speed up the release from the master branch. Considering its dependencies and numerous open issues, I have no hope for this.
