Installation

Via global gems

$ gem install danger-pep8

Via Bundler

Add the following line to your Gemfile and then run bundle install:

gem 'danger-pep8'

Usage

Basic

Check for issues running the script from current directory. Prints a markdown table with all issues found:

pep8.lint

Advanced

Running from a custom directory

Changes root folder from where script is running:

pep8.base_dir = "src"
pep8.lint

Use GitHub's inline comments instead of a markdown table

pep8.lint(use_inline_comments=true)

Running using a configuration file different than the usual

If you need to specify a different configuration file, use the config_file parameter below. Check this link for more information about Configuration Locations.

pep8.config_file = ".flake8_ci"
pep8.lint

Printing a warning message with number of errors

Adds an entry onto the warnings/failures table:

pep8.count_errors

Defining a threshold of max errors

Warns if number of issues is greater than a given threshold:

pep8.threshold = 10
pep8.count_errors

Fails if number of issues is greater than a given threshold:

pep8.threshold = 10
pep8.count_errors(should_fail = true)
