【cesium源码】是一个专为Web开发设计的开源3D地球浏览器的源代码库，主要用JavaScript编写，用于在Web应用中展示高精度的地理空间数据和3D场景。这个压缩包包含了运行和理解Cesium项目所需的核心文件，可以直接在Visual Studio Code (VSCode)中解压并运行。下面我们将详细探讨这些核心文件的作用和Cesium的相关知识点。 1. **gulpfile.js**：Gulp是自动化构建工具，用于简化项目构建流程，如编译、压缩、合并文件等。`gulpfile.js`是Gulp的工作配置文件，定义了不同的任务，如编译源代码、执行测试、创建打包版本等。开发者可以根据这个文件定制自己的构建流程。 2. **server.js**：这是Cesium的本地开发服务器脚本，基于Node.js。运行此文件可以启动一个简单的HTTP服务器，用于在本地预览和测试Cesium应用程序。开发者可以通过修改或扩展此脚本来调整服务器行为。 3. **package.json**：这是Node.js项目的核心配置文件，列出了项目依赖的npm模块和项目的元信息（如作者、版本等）。你可以通过运行`npm install`来安装所有列出的依赖，使得Cesium源码可以在本地环境中正常运行。 4. **CHANGES.md**：这份文件记录了Cesium的版本更新历史，包括每个版本的新特性、改进和已知问题。开发者可以通过阅读此文件了解Cesium的最新发展和可能的兼容性问题。 5. **LICENSE.md**：Cesium使用Apache 2.0许可证，这是一个宽松的开源许可证，允许商业使用。`LICENSE.md`文件详细阐述了使用、复制、分发Cesium源码的法律条款。 6. **README.md**：这是项目的简要介绍，通常包含如何安装、运行和开发Cesium的基本指南。对于新用户来说，这是开始探索Cesium的第一步。 7. **Source**：这个目录包含了Cesium的源代码，分为多个子目录，如`Core`、`Widgets`等，分别存储核心功能和用户界面组件。开发者可以通过阅读源码了解Cesium的实现细节，或者对其进行自定义和扩展。 8. **Specs**：这是单元测试的目录，使用 Jasmine 测试框架编写。这些测试确保Cesium的功能正确无误，并且在后续的开发中保持一致性。 9. **ThirdParty**：这里存放了Cesium依赖的第三方库，例如数学库（如gl-matrix）、图片处理库等，它们是Cesium实现3D渲染和计算的基础。 10. **Build**：这个目录通常用于存放构建过程生成的文件，比如打包后的JavaScript库、CSS样式表等。在实际项目中，你可能会引用这些构建后的文件，而不是源代码。 Cesium源码提供了一个强大的3D地球渲染引擎，适用于Web GIS应用、虚拟现实场景创建等领域。开发者可以利用提供的源代码进行二次开发，定制自己的地图功能，或者学习和研究3D图形渲染、地理空间数据处理等相关技术。通过深入理解和掌握这些核心文件，你可以更有效地利用Cesium构建高性能的Web应用。

The core library provides <em>only</em> the editor component, no accompanying buttons, auto-completion, or other IDE functionality. It does provide a rich API on top of which such functionality can be straightforwardly implemented. See the <a href="#addons">addons</a> included in the distribution, and the <a href="https://github.com/codemirror/CodeMirror/wiki/CodeMirror-addons">list of externally hosted addons</a>, for reusable implementations of extra features.</p> <p>CodeMirror works with language-specific modes. Modes are JavaScript programs that help color (and optionally indent) text written in a given language. The distribution comes with a number of modes (see the <a href="../mode/"><code>mode/</code></a> directory), and it isn't hard to <a href="#modeapi">write new ones</a> for other languages.</p> </section> <section id=usage> <h2>Basic Usage</h2> <p>The easiest way to use CodeMirror is to simply load the script and style sheet found under <code>lib/</code> in the distribution, plus a mode script from one of the <code>mode/</code> directories. For example:</p> <pre data-lang="text/html"><script src="lib/codemirror.js"></script> <link rel="stylesheet" href="lib/codemirror.css"> <script src="mode/javascript/javascript.js"></script></pre> <p>(Alternatively, use a module loader. <a href="#modloader">More about that later.</a>)</p> <p>Having done this, an editor instance can be created like this:</p> <pre data-lang="javascript">var myCodeMirror = CodeMirror(document.body);</pre> <p>The editor will be appended to the document body, will start empty, and will use the mode that we loaded. To have more control over the new editor, a configuration object can be passed to <a href="#CodeMirror"><code>CodeMirror</code></a> as a second argument:</p> <pre data-lang="javascript">var myCodeMirror = CodeMirror(document.body, { value: "function myScript(){return 100;}\n", mode: "javascript" });</pre> <p>This will initialize the editor with a piece of code already in it, and explicitly tell it to use the JavaScript mode (which is useful when multiple modes are loaded). See <a href="#config">below</a> for a full discussion of the configuration options that CodeMirror accepts.</p> <p>In cases where you don't want to append the editor to an element, and need more control over the way it is inserted, the first argument to the <code>CodeMirror</code> function can also be a function that, when given a DOM element, inserts it into the document somewhere. This could be used to, for example, replace a textarea with a real editor:</p> <pre data-lang="javascript">var myCodeMirror = CodeMirror(function(elt) { myTextArea.parentNode.replaceChild(elt, myTextArea); }, {value: myTextArea.value});</pre> <p>However, for this use case, which is a common way to use CodeMirror, the library provides a much more powerful shortcut:</p> <pre data-lang="javascript">var myCodeMirror = CodeMirror.fromTextArea(myTextArea);</pre> <p>This will, among other things, ensure that the textarea's value is updated with the editor's contents when the form (if it is part of a form) is submitted. See the <a href="#fromTextArea">API reference</a> for a full description of this method.</p> <h3 id=modloader>Module loaders</h3> <p>The files in the CodeMirror distribution contain shims for loading them (and their dependencies) in AMD or CommonJS environments. If the variables <code>exports</code> and <code>module</code> exist and have type object, CommonJS-style require will be used. If not, but there is a function <code>define</code> with an <code>amd</code> property present, AMD-style (RequireJS) will be used.</p> <p>It is possible to use <a href="http://browserify.org/">Browserify</a> or similar tools to statically build modules using CodeMirror. Alternatively, use <a href="http://requirejs.org/">RequireJS</a> to dynamically load dependencies at runtime. Both of these approaches have the advantage that they don't use the global namespace and can, thus, do things like load multiple versions of CodeMirror alongside each other.</p> <p>Here's a simple example of using RequireJS to load CodeMirror:</p> <pre data-lang="javascript">require([ "cm/lib/codemirror", "cm/mode/htmlmixed/htmlmixed" ], function(CodeMirror) { CodeMirror.fromTextArea(document.getElementById("code"), { lineNumbers: true, mode: "htmlmixed" }); });</pre> <p>It will automatically load the modes that the mixed HTML mode depends on (XML, JavaScript, and CSS). Do <em>not</em> use RequireJS' <code>paths</code> option to configure the path to CodeMirror, since it will break loading submodules through relative paths. Use the <a
