Python contribution layer for Spacemacs
Table of Contents
Description
This layer adds support for the Python language.
Features:
- Auto-completion using anaconda-mode
- Code Navigation using anaconda-mode
- Documentation Lookup using anaconda-mode and pylookup
- Test Runner using nose.el
- Virtual Environment using pyvenv
- semantic mode is enabled
- Django support via pony-mode
Install
To use this contribution add it to your ~/.spacemacs
(setq-default dotspacemacs-configuration-layers '(python))
Key Bindings
Inferior REPL process
Start a Python or iPython inferior REPL process with SPC m s i.
If ipython is available in system executable search paths, ipython
will be used to launch python shell; otherwise, default python
interpreter will be used. You may change your system executable
search path by activating a virtual environment.
Send code to inferior process commands:
Key Binding | Description
----------------------|------------------------------------------------------------ SPC m s b | send buffer and keep code buffer focused SPC m s B | send buffer and switch to REPL in insert mode SPC m s f | send function and keep code buffer focused SPC m s F | send function and switch to REPL in insert mode SPC m s i | start inferior REPL process SPC m s r | send region and keep code buffer focused SPC m s R | send region and switch to REPL in insert mode CTRL+j | next item in REPL history CTRL+k | previous item in REPL history
Running Python Script in shell
To run a Python script like you would in the shell press SPC m c c to start the Python script in comint mode. This is useful when working with multiple Python files since the REPL does not reload changes made in other modules.
Key Binding | Description
----------------------|------------------------------------------------------------
SPC m c c | Execute current file in a comint shell
SPC m c C | Execute current file in a comint shell and switch to it in insert state
Note With the universal argument SPC u you can enter a new compilation command.
Testing in Python
Spacemacs uses nose as a test runner. An improved version of
nose.el is shipped with Spacemacs, this version adds:
- windows support
- test suite support
The root of the project is detected with a .git directory or a setup.cfg file.
Test commands (start with m t or m T):
No Debug | Description
---------------------|------------------------------------------------------------ SPC m t a | launch all tests of the project SPC m t b | launch all tests of the current buffer (same as module) SPC m t m | launch all tests of the current module SPC m t s | launch all tests of the current suite SPC m t t | launch the current test (function)
Debug | Description
---------------------|------------------------------------------------------------ SPC m T a | launch all tests of the project in debug mode SPC m T b | launch all tests of the current buffer (module) in debug mode SPC m T m | launch all tests of the current module in debug mode SPC m T s | launch all tests of the current suite in debug mode SPC m T t | launch the current test (function) in debug mode
Other Python commands
Key Binding | Description
----------------------|------------------------------------------------------------
SPC m d b | toggle a breakpoint
SPC m g g | go to definition using anaconda-mode-goto (C-o to jump back)
SPC m h h | quick documentation using anaconda
SPC m h H | open documentation in firefox using pylookup
SPC m v | activate a virtual environment with pyvenv
Django
Django related key bindings uses pony-mode and are behind the prefix SPC m j.
Configuration options for pony-mode are documented at deadpansincerity.com
Manage Django with SPC m j m.
