Ideally changes are discrete, documented inline with current standards, and don't contain superficial changes like tab formatting an entire file (hard to accept a PR that has 1000 changes). Don't commit updates to the `dist/` folder, as those will be done by the maintainers at our discretion. 4 | 5 | The classes in this repository are used by many of the classes in the CreateJS suite. Ensure that changes are thoroughly tested, and any changes required in the other repositories are committed, referencing the original pull request in this repository. 6 | 7 | ### Pull Requests 8 | 9 | Our continuous integration processes will lint and test all pull requests. To save time, please lint and test your changes locally, prior to committing. 10 | 11 | Please reference any issues that your PR addresses. 12 | 13 | ### Local Development 14 | 15 | ``` 16 | # clone repo 17 | git clone https://github.com:createjs/core.git 18 | cd path/to/core 19 | # install dependencies and create a symlink 20 | npm install 21 | npm link . 22 | # link core to another lib for testing 23 | cd path/to/easeljs 24 | npm link @createjs/core 25 | ``` 26 | 27 | Documentation for compiling and testing the source can be found in the [build repository README](https://github.com/createjs/build/blob/master/README.md). 28 | 29 | Remember to unlink dependencies when local testing is completed. 30 | -------------------------------------------------------------------------------- /LICENSE.md: -------------------------------------------------------------------------------- 1 | The MIT License (MIT) 2 | 3 | Copyright (c) 2014 gskinner.com, inc. 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.
