A package to include linters in Databricks notebooks: pycodestyle

Linters magic

Magic function for pycodestyle module in Jupyter-Lab or Databricks notebooks.

Current version: 0.1.4

Versions of dependencies:

• python: 3.8
• pycodestyle: 2.8.0
• ipython: 8.1.1

Note that we've tested it only on Databricks notebooks

Installation

pip install lintersmagic

Usage

Enable the magic function by using the lintersmagic module in a cell

%load_ext lintersmagic

To check a cell once:

use the function as first line in your cell to check compliance with pycodestyle as such:

%%pycodestyle

To auto check each cell:

If you want this compliance checking turned on by default for each cell then run this magic line function in an empty cell:

%pycodestyle_on

You only need to call this once (observe the single %).

To turn off the auto-checking for each cell use:

%pycodestyle_off

Config options for %pycodestyle_on (version >= 0.5)

1. The option --ignore or -i will add the the named error(s) to the ignore list

Example to ignore the errors E225 and E265:

%pycodestyle_on --ignore E225,E265

Remember to avoid spaces between declaring multiple errors.

2. With the option --max_line_length or -m the max-line-length can be customised.

Example to set the line length to 119 characters instead of the default 79:

%pycodestyle_on --max_line_length 119

The options can be combined as well.

See notebooks in notebook directory for example use cases, as such:
