GlslEditor

Friendly GLSL Shader editor based on Codemirror compatible with glslViewer (C++/OpenGL ES) and glslCanvas (JS/WebGL).

Was originally develop to work as a embedded editor for The Book of Shaders. But now have grown as a stand alone Web app. Thanks to their compatibility with other apps of this ecosystems like glslViewer that runs in the RaspberryPi directly from console, GlslEditor interact with other projects like OpenFrame.io allowing the user to export the shaders to frames with only one button.

You can use it directly from editor.thebookofshaders.com or host one on your own website by including the two build files: glslEditor.css and glslEditor.js:

<link type="text/css" rel="stylesheet" href="https://rawgit.com/patriciogonzalezvivo/glslEditor/gh-pages/build/glslEditor.css">
<script type="application/javascript" src="https://rawgit.com/patriciogonzalezvivo/glslEditor/gh-pages/build/glslEditor.js"></script>

You can also install it through npm:

npm install glslEditor --save

And then you are ready to use it by passing an DOM element or query selector string, and a set of options;

<body>
    <div id="glsl_editor"></div>
</body>
<script type="text/javascript">
    const glslEditor = new GlslEditor('#glsl_editor', { 
        canvas_size: 500,
        canvas_draggable: true,
        theme: 'monokai',
        multipleBuffers: true,
        watchHash: true,
        fileDrops: true,
        menu: true
    });
</script>

This is a list of all the options you can set up:

| Property | type | description | default | |----------------------|------|---|-----| | canvas_size |number| Initial square size of the shader canvas |250| | canvas_width |number| Initial width of the shader canvas |250| | canvas_height |number| Initial height of the shader canvas |250| | canvas_draggable| bool | Enables dragging, resizing and snaping capabilities to the shader canvas |false| | canvas_follow | bool | Enables the shader canvas to follow the curser |false| | theme | string | Codemirror style to use on the editor |"default"| | menu | bool | Adds a menu that contain: 'new', 'open', 'save' and 'share' options | false| | multipleBuffers | bool | Allows the creation of new tabs |false| | fileDrops | bool | Listen to Drag&Drop events |false| | watchHash| bool | Listen to changes on the wash path to load files |false| | frag_header | string| Adds a hidden header to every shader before compiling |""| | frag_footer | string| Adds a hidden footer to every shader before compiling |""| | indentUnit | number | How many spaces a block should be indented | 4 | | tabSize | number | The width of a tab character | 4 | | indentWithTabs | bool | Whether, when indenting, the spaces should be replaced by tabs | false | | lineWrapping | bool | Whether CodeMirror should wrap for long lines | true | | autofocus | bool | Can be used to make CodeMirror focus itself on initialization | true |
