--------------------------------------------------------------------------------
 1 | # Contributor Covenant Code of Conduct
 2 | 
 3 | ## Our Pledge
 4 | 
 5 | In the interest of fostering an open and welcoming environment, we as
 6 | contributors and maintainers pledge to making participation in our project and
 7 | our community a harassment-free experience for everyone, regardless of age, body
 8 | size, disability, ethnicity, sex characteristics, gender identity and expression,
 9 | level of experience, education, socio-economic status, nationality, personal
10 | appearance, race, religion, or sexual identity and orientation.
11 | 
12 | ## Our Standards
13 | 
14 | Examples of behavior that contributes to creating a positive environment
15 | include:
16 | 
17 | * Using welcoming and inclusive language
18 | * Being respectful of differing viewpoints and experiences
19 | * Gracefully accepting constructive criticism
20 | * Focusing on what is best for the community
21 | * Showing empathy towards other community members
22 | 
23 | Examples of unacceptable behavior by participants include:
24 | 
25 | * The use of sexualized language or imagery and unwelcome sexual attention or
26 |   advances
27 | * Trolling, insulting/derogatory comments, and personal or political attacks
28 | * Public or private harassment
29 | * Publishing others' private information, such as a physical or electronic
30 |   address, without explicit permission
31 | * Other conduct which could reasonably be considered inappropriate in a
32 |   professional setting
33 | 
34 | ## Our Responsibilities
35 | 
36 | Project maintainers are responsible for clarifying the standards of acceptable
37 | behavior and are expected to take appropriate and fair corrective action in
38 | response to any instances of unacceptable behavior.
39 | 
40 | Project maintainers have the right and responsibility to remove, edit, or
41 | reject comments, commits, code, wiki edits, issues, and other contributions
42 | that are not aligned to this Code of Conduct, or to ban temporarily or
43 | permanently any contributor for other behaviors that they deem inappropriate,
44 | threatening, offensive, or harmful.
45 | 
46 | ## Scope
47 | 
48 | This Code of Conduct applies both within project spaces and in public spaces
49 | when an individual is representing the project or its community. Examples of
50 | representing a project or community include using an official project e-mail
51 | address, posting via an official social media account, or acting as an appointed
52 | representative at an online or offline event. Representation of a project may be
53 | further defined and clarified by project maintainers.
54 | 
55 | ## Enforcement
56 | 
57 | Instances of abusive, harassing, or otherwise unacceptable behavior may be
58 | reported by contacting the project team at [INSERT EMAIL ADDRESS]. All
59 | complaints will be reviewed and investigated and will result in a response that
60 | is deemed necessary and appropriate to the circumstances. The project team is
61 | obligated to maintain confidentiality with regard to the reporter of an incident.
62 | Further details of specific enforcement policies may be posted separately.
63 | 
64 | Project maintainers who do not follow or enforce the Code of Conduct in good
65 | faith may face temporary or permanent repercussions as determined by other
66 | members of the project's leadership.
67 | 
68 | ## Attribution
69 | 
70 | This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
71 | available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

 1 | # 💻 Contributing to DifferenceKit
 2 | 
 3 | First of all, thanks for your interest in DifferenceKit.  
 4 | 
 5 | There are several ways to contribute to this project. We welcome contributions in all ways.  
 6 | We have made some contribution guidelines to smoothly incorporate your opinions and code into this project.  
 7 | 
 8 | ## 📝 Open Issue
 9 | 
10 | When you found a bug or having a feature request, search for the issue from the [existing](https://github.com/ra1028/DifferenceKit/issues) and feel free to open the issue after making sure it isn't already reported.  
11 | 
12 | In order to we understand your issue accurately, please include as much information as possible in the issue template.  
13 | The screenshot are also big clue to understand the issue.  
14 | 
15 | If you know exactly how to fix the bug you report or implement the feature you propose, please pull request instead of an issue.  
16 | 
17 | ## 🚀 Pull Request
18 | 
19 | We are waiting for a pull request to make this project more better with us.  
20 | If you want to add a new feature, let's discuss about it first on issue.  
21 | 
22 | ```bash
23 | $ git clone https://github.com/ra1028/DifferenceKit.git
24 | $ cd DifferenceKit/
25 | $ open DifferenceKit.xcworkspace
26 | ```
27 | 
28 | ### Lint
29 | 
30 | Please introduce [SwiftLint](https://github.com/realm/SwiftLint) into your environment before start writing the code.  
31 | Xcode automatically runs lint in the build phase.  
32 | 
33 | The code written according to lint should match our coding style, but for particular cases where style is unknown, refer to the existing code base.  
34 | 
35 | ### Test
36 | 
37 | The test will tells us the validity of your code.  
38 | All codes entering the master must pass the all tests.  
39 | If you change the code or add new features, you should add tests.  
40 | 
41 | ### Documentation
42 | 
43 | Please write the document using [Xcode markup](https://developer.apple.com/library/archive/documentation/Xcode/Reference/xcode_markup_formatting_ref/) to the code you added.  
44 | Documentation template is inserted automatically by using Xcode shortcut **⌥⌘/**.  
45 | Our document style is slightly different from the template. The example is below.  
46 | ```swift
47 | /// The example class for documentation.
48 | final class Foo {
49 |     /// A property value.
50 |     let prop: Int
51 | 
52 |     /// Create a new foo with a param.
53 |     ///
54 |     /// - Parameters:
55 |     ///   -  param: An Int value for prop.
56 |     init(param: Int) {
57 |         prop = param
58 |     }
59 | 
60 |     /// Returns a string value concatenating `param1` and `param2`.
61 |     ///
62 |     /// - Parameters:
63 |     ///   - param1: An Int value for prefix.
64 |     ///   - param2: A String value for suffix.
65 |     ///
66 |     /// - Returns: A string concatenating given params.
67 |     func bar(param1: Int, param2: String) -> String {
68 |         return "\(param1)" + param2
69 |     }
70 | }
71 | ```
72 |
