Correction 77 | 78 | **Community Impact**: Use of inappropriate language or other behavior deemed 79 | unprofessional or unwelcome in the community. 80 | 81 | **Consequence**: A private, written warning from community leaders, providing 82 | clarity around the nature of the violation and an explanation of why the 83 | behavior was inappropriate. A public apology may be requested. 84 | 85 | ### 2. Warning 86 | 87 | **Community Impact**: A violation through a single incident or series 88 | of actions. 89 | 90 | **Consequence**: A warning with consequences for continued behavior. No 91 | interaction with the people involved, including unsolicited interaction with 92 | those enforcing the Code of Conduct, for a specified period of time. This 93 | includes avoiding interactions in community spaces as well as external channels 94 | like social media. Violating these terms may lead to a temporary or 95 | permanent ban. 96 | 97 | ### 3. Temporary Ban 98 | 99 | **Community Impact**: A serious violation of community standards, including 100 | sustained inappropriate behavior. 101 | 102 | **Consequence**: A temporary ban from any sort of interaction or public 103 | communication with the community for a specified period of time. No public or 104 | private interaction with the people involved, including unsolicited interaction 105 | with those enforcing the Code of Conduct, is allowed during this period. 106 | Violating these terms may lead to a permanent ban. 107 | 108 | ### 4. Permanent Ban 109 | 110 | **Community Impact**: Demonstrating a pattern of violation of community 111 | standards, including sustained inappropriate behavior, harassment of an 112 | individual, or aggression toward or disparagement of classes of individuals. 113 | 114 | **Consequence**: A permanent ban from any sort of public interaction within 115 | the community. 116 | 117 | ## Attribution 118 | 119 | This Code of Conduct is adapted from the [Contributor Covenant][homepage], 120 | version 2.0, available at 121 | https://www.contributor-covenant.org/version/2/0/code_of_conduct.html. 122 | 123 | Community Impact Guidelines were inspired by [Mozilla's code of conduct 124 | enforcement ladder](https://github.com/mozilla/diversity). 125 | 126 | [homepage]: https://www.contributor-covenant.org 127 | 128 | For answers to common questions about this code of conduct, see the FAQ at 129 | https://www.contributor-covenant.org/faq.

Below are some scenarios where you could contribute and how to do so.** Contributions are generally accepted when they help achieve at least one of the aims below, but others will be considered: 4 | 5 | * The `code-input` element should act like a normal HTML `textarea` in all browsers, working with all of the normal attributes, events and other types of behaviour. 6 | * The `code-input` element should be easy to use with all popular syntax-highlighting libraries. 7 | * Any modifications of `code-input` that would be useful for the open-source community but are not core to this functionality should be available as optional plugins in the `plugins` folder. Here's where most feature contributions will go. 8 | 9 | We will generally *not* consider the following contributions: 10 | * Excess functionality and/or complexity in the main code-input files - these types of contributions should go in the plugin folder instead. 11 | * Issues that have been closed as not planned in the past (you can search the issue list to check), unless you bring a change that overcomes the reason they were not planned. 12 | 13 | This said, if you're not sure whether your change will be accepted, please ask in an issue. 14 | 15 | --- 16 | 17 | To keep this community productive and enjoyable, please [don't break our code of conduct](https://github.com/WebCoder49/code-input/blob/main/CODE_OF_CONDUCT.md). 18 | 19 | --- 20 | # Ways you could contribute: 21 | ## 1. I've found a bug but don't know how / don't have time to fix it. 22 | If you think you've found a bug, please [submit an issue](https://github.com/WebCoder49/code-input/issues) with screenshots, how you found the bug, and copies of the console's logs if an error is in them. Please also mention the template and plugins you used (your `codeInput.registerTemplate(...)` snippet). We'd be more than happy to help you fix it. A demo using [CodePen](https://codepen.io/) would be incredibly useful. 23 | 24 | ## 2. I have implemented a feature / have thought of a potential feature for the library and think it could be useful for others. 25 | The best way to implement a feature is as a plugin like those in the `plugins` folder of `code-input`. If you do this, you could contribute it as in point 3 below. 26 | Otherwise, if you do not have the time needed / do not want to implement it, any potential plugins would be [welcome as an Issue](https://github.com/WebCoder49/code-input/issues) which specifies the uses and desired characteristics. 27 | 28 | ## 3. I want to contribute code that I need / have seen in the Issues. 29 | Firstly, thank you for doing this! This is probably the most time consuming way of contributing but is also the most rewarding for both you and me as a maintainer. 30 | 31 | Please first open an issue if one doesn't already exist, and assign yourself to it. Then, [make a fork of the repo and submit a pull request](https://docs.github.com/en/get-started/quickstart/contributing-to-projects). 32 | 33 | In the pull request, include the code updates for your feature / bug, and if you're adding a new feature make sure you comment your code so it's understandable to future contributors, and if you can, add unit tests for it in tests/tester.js. If you have any questions, just let me (@WebCoder49) know! 34 | 35 | If an issue is open but already assigned to someone, it is probably already being worked on - you could still suggest a method of fixing it in the comments but shouldn't open a pull request as it would waste your time. 36 | -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | MIT License 2 | 3 | Copyright (c) 2021 WebCoder49 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.

It uses vanilla CSS to superimpose a `textarea` on a `pre code` block, then handles indentations, scrolling and fixes any resulting bugs with JavaScript. To see how it works behind the scenes (not how to use this library), please see [this CSS-Tricks article](https://css-tricks.com/creating-an-editable-textarea-that-supports-syntax-highlighted-code/ "Creating an Editable Textarea That Supports Syntax-Highlighted Code") I wrote. 19 | 20 | ## What are the advantages of using code-input, and what can it be used for? 21 | Unlike other front-end code-editor projects, the simplicity of how `code-input` works means it is **highly customisable**. As it is not a full-featured editor, you can **choose what features you want it to include, and use your favourite syntax-highlighting algorithms and themes**. 22 | 23 | The `` element works like a ` 152 | 153 | 154 | 155 | 156 | 157 | 158 | 159 | 160 | 161 | 162 | 196 | 197 | 198 | -------------------------------------------------------------------------------- /tests/prism-match-braces-compatibility.js: -------------------------------------------------------------------------------- 1 | /* Modified from https://cdnjs.cloudflare.com/ajax/libs/prism/1.29.0/plugins/match-braces/prism-match-braces.js 2 | to enable codeInput SelectTokenCallbacks compatibility.

This page carries out automated tests for the code-input library to check that both the core components and the plugins work in some ways. It doesn't fully cover every scenario so you should test any code you change by hand, but it's good for quickly checking a wide range of functionality works.
