## Emacs

### Your package manager Emacs 24 or beta

1.  On Arch: $ sudo pacman -S emacs

### Config is in `~/.emacs.d/init.el`

### M-x means Alt+x

### C-x means Ctrl+x (or Caps+x ?)

## ElPy

### Elpy >= Python mode+Rope+PyLint+many more

```
Installation

Emacs: M-x package install ENTER elpy

Then in your init.el

(elpy-enable)
;; Your virtual environment?

Takes 5 mins... you are welcome!
```

### Keyboard shortcuts

1.  C-c C-c - Evaluate region/buffer by sending to inferior python

2.  C-c C-d - Show documentation at cursor symbol

3.  M-.     - Go to definition (better than docs for Django)

    - https://github.com/DjangoPatternsBook/superbook/blob/chapter03/src/profiles/models.py

4.  C-c C-o - Show class/fn definitions in buffer as Occur window

5.  C-UP/DN - Jump to prev class definition line (corresp for C-DOWN)

6.  M-LF/RT - Move indented block starting from line where cursor is RIGHT(indent) or LEFT(unindent
