emacs configuration file

Posted on

In this post, we start to explore the magic of emacs: customized configuration files for emacs. The magic feature of emacs is the extensibility. Comparing to Vim, which is the specialist as a editor. Emacs is more like an single thread operating system which runs as an editor. In order to explore the magic, we start from the basic extended configurations for the emacs.

Normally, emacs configuration files locate in directory ~/.emacs.d or ~/.emacs. The help information for Minor mode and Major mode can be explored by pressing key C-h m.

M-x package-list-packages lists all the packages can be installed.

Sevearl packages I installed in my personal emacs configuration file: auto-complete
