Use Vim as a Python IDE

This is a general guide for using SpaceVim as a Python IDE, including layer configuration and usage. Each of the following sections will be covered:

Enable language layer
Code completion
Syntax linting
Import packages
Jump to test file
running code
Code formatting
REPL

Enable language layer

To add Python language support in SpaceVim, you need to enable the lang#python layer. Press SPC f v d to open SpaceVim configuration file, and add the following snippet to your configuration:

[[layers]]
  name = "lang#python"

For more info, you can read the lang#python layer documentation.

Code completion

lang#python layer will load the jedi plugin automatically, unless overriden in your init.toml. The completion menu will be opened as you type.

Syntax linting

The checkers layer is enabled by default. This layer provides asynchronous syntax linting via neomake. It will run flake asynchronously.

To install flake8, just run following command in terminal.

pip install --user flake8

Import packages

When edit Python file, you can import the package automatically, remove unused package and format package list.

pip install --user isort

Jump to test file

SpaceVim use built-in plugin to manager the files in a project, you can add a .project_alt.json to the root of your project with following content:

{
  "src/*.py": {"alternate": "test/{}.py"},
  "test/*.py": {"alternate": "src/{}.py"}
}

with this configuration, you can jump between the source code and test file via command :A.

running code

To run current script, you can press SPC l r, and a split window will open, the output of the script will be shown in this window. It is running asynchronously, and will not block your Vim.

Code formatting

The format layer is also enabled by default, with this layer you can use key binding SPC b f to format current buffer. Before using this feature, please install yapf.

pip install --user yapf

REPL

Start a ipython or python inferior REPL process with SPC l s i. After the REPL process being started, you can send code to inferior process. All key bindings prefix with SPC l s, including sending line, sending selection or even send whole buffer.
