-------------------------------------------------------------------------------- 1 | Contributing 2 | ============ 3 | 4 | Thank you for your interest! 5 | Issue and pull request are welcome! 6 | 7 | 8 | Development and Testing 9 | ----------------------- 10 | We are weolcoming tha refactoring and implements operators. 11 | 12 | `rx` provides attractive code to users, like the general `std.range` and `std.algorithm`. But, its source code is unfortunately complicated. 13 | 14 | In particular, it is important a variety operators combination tests, and multithreading tests. 15 | 16 | ### Things you will need 17 | 18 | * Linux, Mac OS X, or Windows 19 | * git (used for source version control). 20 | * Some D Compiler. dmd and ldc. 21 | * Latest dub (used for build and testing). 22 | * An IDE. We recommend [Visual Studio Code](https://code.visualstudio.com/download) with [code-d](https://marketplace.visualstudio.com/items?itemName=webfreak.code-d). 23 | * Use dfmt (with default settings) for code formatting. 24 | 25 | ### Patterns 26 | Taking `map` as an example, the operator consists of the following three elements. 27 | 28 | - struct `MapObserver` 29 | - struct `MapObservable` 30 | - template function `map` 31 | 32 | #### MapObserver 33 | Observer's role is to provide concrete algorithms in the constructed pipeline. 34 | 35 | `MapObserver` has the function of passing processed values to Observer as source. 36 | 37 | #### MapObservable 38 | Observable as an operator has Observable as a source and has the role of processing a given Observer and constructing a pipeline. 39 | 40 | `MapObservable` has the function of wrapping the passed Observer in `MapObserver` and subscribing to Observable as source. 41 | 42 | Also, since Observable returns `Disposable`, it relays it. 43 | 44 | #### map 45 | It is utility function for build `MapObservable`. 46 | 47 | 48 | ### Naming priority 49 | Unified naming conventions is important. It is now as follows. 50 | 51 | 1. Look for similar operators from `std.algorithm`. 52 | 2. If there are no similar operators, follow [Reactive X](http://reactivex.io/documentation/operators.html). 53 | 54 | 55 | Documentation 56 | ------------- 57 | We are welcoming the tutorial documentation. 58 | 59 | For users, the goal is to think about the composition of the tutorial so that you can see how to use it, and to add practical examples. 60 | 61 | For developers, We think that the following things are necessary. 62 | 63 | - Manage the tutorial as part of the source. 64 | - Since the contribution log remains, it is easy to understand later. 65 | - Not separate it into another repository to avoid version inconsistency. 66 | - Keep docs as a simple API reference. 67 | -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | MIT License 2 | 3 | Copyright (c) 2016 4 | 5 | Permission is hereby granted, free of charge, to any person obtaining a copy 6 | of this software and associated documentation files (the "Software"), to deal 7 | in the Software without restriction, including without limitation the rights 8 | to use, copy, modify, merge, publish, distribute, sublicense, and/or sell 9 | copies of the Software, and to permit persons to whom the Software is 10 | furnished to do so, subject to the following conditions: 11 | 12 | The above copyright notice and this permission notice shall be included in all 13 | copies or substantial portions of the Software. 14 | 15 | THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR 16 | IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, 17 | FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
