elpy's Introduction

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: Looking for a maintainer

I find myself (@galaunay, current maintainer), unable to maintain Elpy at the moment, and probably for a while. If you are interested in getting involved in Elpy, please contact me by mail, the project definitely needs you !

In the meantime, I will keep an eye on the PRs to integrate any fix and/or new features proposed, but I will definitely not be able to treat the issues in a satisfying manner. If you are stuck with an issue, please have a look at the documentation, there is a lot of answers there. @gfederix also made some bug fixing in his fork, so you can try using this version of Elpy.

Features

Installation

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.

Quickstart

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.

elpy's Issues

The refactoring window breaks window layout and point position

When confirming a refactoring action, it would be good if the previous window configuration was restored.

Also, after the refactoring action, point should be where it was before, or at least thereabouts.

Better error reporting and help during pymacs requires

When requiring pymacs modules, the error is less than informative (e.g. "no response in time ..."). Check for installation of individual modules by hand and make a sensible, per-module error report.

Automate installation of python packages

On an import error, instead of displaying installation instructions, offer to install things instead.

Options: abort, install, try again (so users can install themselves).

python-check.sh is not part of the marmalade package

This needs to be documented well, and a download link specified:

https://raw.github.com/jorgenschaefer/elpy/master/python-check.sh

`M-*` should return to the last "follow symbol" call

Basically the inverse of M-..

pyde-doc-rope does not find symbols correctly

If there is no documentation available at point, pyde-doc-rope should go to the beginning of the statement and try again, because the following does not work:

datetime.datetime.strptime(_|_

pydoc does not see virtualenv packages

When using C-u C-c C-d, the pydoc call does not actually see packages in the current virtualenv.

Better Python backend

RopeMacs, Pymacs, etc. is quite heavy, especially as I (personally) mainly use it to get possible completions. We could see if we can rewrite that part.

Define an RPC protocol between Python and Emacs we can use. Probably JSON-based.
Use available completion helpers (from rope, jedi, rlcompleter, own stuff?)

How to use Rope as a library:

http://rope.sourceforge.net/library.html

Especially the codehelper part is relevant.

TAB completion bound to yas/expand rather than ac-trigger-key

Installing elpy 0.8 and yasnippet 0.8.0 from marmalade, the TAB key is bound to yas/expand rather than ac-trigger-key. Furthermore, C-c C-i is bound to python-find-imports rather than yasnippet-expand.

I am using GNU Emacs 24.2.1 (x86_64-pc-linux-gnu, GTK+ Version 2.24.10) of 2012-11-08 on lakoocha, modified by Debian.

Add an elpy-features configuration variable

elpy enables a number of modes and add-ons. Add a variable that allows users to configure which should be used, in case they dislike one.

'pip install elpy' fails

I am trying to install elpy. Following the documentation, I started with pip install elpy

$ pip install elpy
Downloading/unpacking elpy
  Could not find any downloads that satisfy the requirement elpy
No distributions at all found for elpy
Storing complete log in /Users/xiao/.pip/pip.log

The log is gisted https://gist.github.com/4699824

Any ideas?

Make Pymacs available via PyPI

Pymacs should be available via PyPI.

I've sent the author an email to see if we can get that sorted.

Release 0.9

Release the v0.9 release candidate

Refactoring option: Add imports

The refactoring option should walk through the current file and find undefined symbols, trying to see if they can be imported from known modules. Such symbols should be added as import statements.

python-nav-beginning-of-statement not defined

Before Emacs 24.3, python-nav-beginning-of-statement was not defined. python-nav-backward-sencen is, though.

Rope refactoring support

Elpy should provide an interface to the Rope refactoring interface.

Ideally, the Jedi backend would default to Rope for things it can't handle itself.

pyde-doc-show uses wrong anchor

It's missing the module name from the anchor. I.e. "decimal.Context.add" is trying to link to "Context.add" only.

Support jedi

New source for completions:

https://github.com/davidhalter/jedi

Better python-check support

Pyde should be smart about finding an appropriate check command, and also tell the user if none is found.

flymake throws errors for symlinked paths

When using heavily symlinked paths for a project, flymake can throw an error because the relative path generated does not work due to symlinks.

elpy-flymake-python-init probably can do without relative paths?

Provide "import" completion for rope

"import " and "from " should provide completions for Python modules and packages. The module list can be easily supplied using pkgutil.iter_modules.

This only really affects rope.

elpy-flymake-python-init sometimes gets file names wrong

Apparently, this function can pass a wrong file name to the function. It'd probably be a better idea not to use file-relative-name?

Autocompletion problem

I think there's a problem with the autocompletion feature. For example, after an 'import os' and typing 'os.' I get a popup with invalid values (e.g. nt, ce, os2, sep, ...). These items also don't have any help attached.

I can reproduce this on OS X and Ubuntu.

Define default virtual environment?

Hi,

is there any way to define a default virtual environment so I can use a custom installation without either meddling with the system paths or calling virtualenv-workon every time I fire up elpy?

best regards,
Sebastian

Performance issues

There's a very noticeable (order of magnitude a second, I'd guess) delay when typing.

I've tried the following things:

disabling python-check.sh
disabling flymake entirely
removing (elpy-use-ipython)
increasing ac delays ((setq ac-auto-show-menu 1.0) (setq ac-quick-help-delay 1.2) and also the same thing with 2.0 and 2.2 as delays)
moving the ropeproject to be inside my package instead of the repository toplevel directory (just in case it was accidentally trying to index the whole virtualenv)

... but so far nothing helps :(

Here's a video showing the issue writing a simple example class (a WTForms validator); my keyboard typing on the audio track so you can see the sync issue:

https://dl.dropbox.com/u/38476311/elpyperformanceissue.mov

(It's AAC/H.264; please let me know if you have issues viewing it and I'll convert it to something else.)

I'm running a fully updated current-generation Macbook Air with OS X 10.8 and Emacs for OS X. Any help is very appreciated :)

iedit integration

Elpy should depend on iedit, which is an awesome package.

We might hook this up to jedi.Script.related_names at some point, too.

Release 1.0

Remember the blog post and the champagne.

Completion sometimes causes an error

I'm not quite sure where this comes from. It looks like a bug in popup.el, but I'm not sure.

elpy

Just installed elpy, haven't run it yet.

Got an error starting emacs, claimed that highlight-indentation wasn't available.

I installed highlight-indentation from package-list-packages and restarted, which fixed the problem.

Thanks,

Asynchronous auto-complete

AC does call the candidate function for every character typed. We can improve interactive speed by doing an asynchronous call and only wait at most a very small amount of time for a response. If we cache the response appropriately, typing further characters would give more results.

It might even be possible to call auto-complete again on a callback if point hasn't moved...

Native backend should auto-import modules

The native backend's completion is very limited at the moment, as it does not import modules at all. Auto-importing modules has problems, though, as it can trigger code execution that's not intended.

namespace = dict(sys.modules["__main__"].__dict__)
namespace['multiprocessing'] = __import__("multiprocessing")
c = rlcompleter.Completer(namespace)

Rework keybindings

The current elpy keymap is very much "organically grown". Should be reworked completely.

when pyde is installed it automatically removes trailing whitespaces

Hi,

I've been using pyde lately and i found that it removes trailing whitespaces silently at save. This is causing me headaches since i've a lot of trailing whitespaces commits.

How can i disable that? Is it a wanted feature or a bug?

Flymake support

Pyde should integrate with Flymake by default as with the other packages.

python-check-command not set by elpy to python-checker.sh; uses python.el default

C-h v python-check-command gives me:

python-check-command is a variable defined in `python.el'.
Its value is "pychecker --stdlib"

  This variable is potentially risky when used as a file local variable.

Documentation:
Command used to check a Python file.

I was expecting the python-check.sh, now shipped with elpy, and set by elpy.

Am I still supposed to set this variable in Git HEAD?

(Also, the Wiki still references python-check.sh with wget; should I remove it?)

More snippets

Yasnippet could do with a load of more snippets.

Example on how to install snippets:

https://github.com/mpenet/clojure-snippets/blob/master/clojure-snippets.el

Virtualenv: Notify user of running Pymacs and Python processes

Pop up a window and offer to restart those for the user on a button press, maybe?

Use flymake-style temp files for large buffers

When we're completing a large buffer, transferring the full buffer contents via JSON is very slow. Instead, we could pass the contents as a temporary file much like flymake if the buffer size exceeds a certain value.

Should do some tests to see if this is slower or faster for small buffers, too.

Python interpreter to be used should be configurable

Currently, "python" is hardcoded for the backend. This should be configurable.

(wrong-type-argument stringp nil) in latest git head

Since updating to latest git head, I get the following error on startup (well, this is the backtrace I get when I pass --debug-init):

Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  file-exists-p(nil)
  (if (file-exists-p python-check) (progn (defvar python-check-command python-check "Command used to check a Python file.")))
  (when (file-exists-p python-check) (defvar python-check-command python-check "Command used to check a Python file."))
  (let* ((elpy-el (or byte-compile-current-file buffer-file-name)) (python-check (when elpy-el (concat (file-name-directory elpy-el) "python-check.sh")))) (when (file-exists-p python-check) (defvar python-check-command python-check "Command used to check a Python file.")))
  eval-buffer(#<buffer  *load*<2>> nil "/Users/lvh/.emacs.d/elpy/elpy.el" nil t)  ; Reading at buffer position 1965

This happens regardless of whether or not I set python-check-command. python-check's value is nil, but that might be related to the error.

pyde-doc-show should use incremental complete

Like file names and directories.

Pydoc completion should be interactive

Using pkgutil.iter_modules, we could make the C-u C-c C-d interactive.

Include nosemacs and/or pytest.el support

pytest: https://bitbucket.org/elarson/pytest.el
nose: https://bitbucket.org/durin42/nosemacs

`elpy-mode-hook` is missing

elpy.el should define an elpy-mode-hook' variable. That should be run by define-minor-mode.

Use highlight-indentation-mode

https://github.com/antonj/Highlight-Indentation-for-Emacs/

It's in marmalade, but only 0.5, not 0.6 ...

Refactoring command fails on OS X/Emacs trunk

Hi,

first of all, thanks alot for fixing my recent virtualenv-related issue so quickly! I have noticed that C-c C-r does not work for me; Emacs returns the following error message: "elpy-rpc-call: Unknown method get_refactor_options". The elpy python module has been installed, although it resides in a virtual environment (which seems to work well in all other regards, including pydoc support, autocompletion, etc.). Is this a known bug or might I still be missing some dependencies?
best,
Sebastian
