Key Bindings

Inferior REPL process

Start a Python or iPython inferior REPL process with SPC m 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 b | send buffer and keep code buffer focused SPC m B | send buffer and switch to REPL in insert mode SPC m f | send function and keep code buffer focused SPC m F | send function and switch to REPL in insert mode SPC m r | send region and keep code buffer focused SPC m R | send region and switch to REPL in insert mode CTRL+j | next item in REPL history CTRL+k | previous item in REPL history

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):

 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
