GlslEditor

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

Was originaly develop to work as a embebed 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	`""`
