danger-swiftformat

A Danger plugin to check Swift formatting using SwiftFormat.

This plugin is heavily inspired by danger-swiftlint.

Installation

Add this line to your Gemfile:

gem 'danger-swiftformat'

SwiftFormat also needs to be installed before you run Danger.

Usage

Add this to your Dangerfile

swiftformat.check_format

By default, danger-swiftformat will check added and modified files.

Options and parameters

If you want errors to fail Danger, you can use the fail_on_error option:

swiftformat.check_format(fail_on_error: true)

You can specify the swiftformat binary using the binary_path parameter:

swiftformat.binary_path = "/path/to/swiftformat"

You can specify the Swift version of your project using the swiftversion parametter:

swiftformat.swiftversion = "5"

You can specify additional swiftformat arguments using the additional_args parameter:

swiftformat.additional_args = "--indent tab --self insert"

You can specify additional message (e.g. how to fix format issue) for danger comment using the additional_message parameter:

swiftformat.additional_message = "your additional message for contributor"

By default, danger-swiftformat will run on any modified or created file ending in .swift. If you'd like to exclude certain directories or files such as Pods, you can use the exclude parameter:

swiftformat.exclude = %w(Pods/** Carthage/** Sources/Nope.swift **/*_autogenerated.swift)

If you want the format results shows in the diff instead of a comment, you can use the inline_mode option. Violations that are out of the diff will be shown in danger's fail or warn section:

swiftformat.inline_mode = true

The exclude option takes an array of glob patterns; you can find additional documentation on the patterns here.
