My emacs configuration for Python development

Emacs Side

Copy .emacs to ~/

 cp .emacs ~/

Python Side

Install packages from requrements.txt

 pip install -r requirements.txt

Virtual Environment

If you're using the virtual environment then copy .dir-locals.el to your project root (usually git dir) and replace YOUR_ENV with particular venv name. See https://github.com/porterjamesj/virtualenvwrapper.el for details.

  cp .dir-locals.el your/project/dir/
  vi .dir-locals.el

To exclude this file locally (if you don't want to put it to .gitignore) add it to the file .git/info/exclude.

vim .git/info/exclude

or

git update-index --assume-unchanged .dir-locals.el

Fonts installation

Emacs configuration can use different fonts (like Dejavu, Consolas), please install them if needed. For instance OS X install process:

  brew tap caskroom/fonts
  brew cask install font-dejavu-sans
  brew cask install font-consolas-for-powerline

Projectile configuration

The .projectile file contains all projectile configurations, please adapt it to your project (see http://projectile.readthedocs.io/en/latest/).

  cp .projectile your/project/dir/
  vi .projectile
