Elpy, the Emacs Python IDE
Elpy is an Emacs package to bring powerful Python editing to Emacs. It combines and configures a number of other packages, both written in Emacs Lisp as well as Python. Elpy is fully documented at Readthedocs.
IMPORTANT NOTE: Current support
I find myself (@galaunay, current maintainer), unable to maintain Elpy at the moment, and probably for a while. I will keep an eye on the PRs to integrate any fix and/or new feature proposed, but I will definitely not be able to treat the issues in a satisfying manner.
- Code completion
- Code Navigation
- Interactive Python shell
- Virtualenv support
- On-the-fly syntax checking
- Access to documentation
- Snippet Expansion
- Code hinting
Elpy is available on Melpa, the most straightforward way to install it is to use use-package:
(use-package elpy :ensure t :init (elpy-enable))
For other installation alternatives, see the documentation section Installation.
Once installed, Elpy will automatically provide code completion, syntax error highlighting and code hinting (in the modeline) for python files. Elpy offers a lot of features, but the following keybindings should be enough to get started:
- C-c C-c evaluates the current python script (or region if something is selected) in an interactive python shell. The python shell is automatically displayed aside of your script.
- C-RET evaluates the current statement (current line plus the following nested lines).
- C-c C-z switches between your script and the interactive shell.
- C-c C-d displays documentation for the thing under cursor. The documentation will pop in a different buffer, that can be closed with q.
Please have a look at the documentation at Readthedocs if you want to know more about what Elpy can do.
