[bug?] Doesn't work when chained in a single module.loaders config, but works with multiple.

[trusktr]

If I have this webpack config:

module.exports = {
    resolve: {
        extensions: [ "", ".js", ".jsx", ".glsl" ]
    },
    module: {
        loaders: [
            { test: /\.jsx?$/,  loader: 'babel', exclude: /node_modules/ },
            { test: /\.glsl$/, loader: 'glslify!raw' },
        ],
    },
}

compiling a project with .glsl files has error like this:

but if I instead have this config:

module.exports = {
    resolve: {
        extensions: [ "", ".js", ".jsx", ".glsl" ]
    },
    module: {
        loaders: [
            { test: /\.jsx?$/,  loader: 'babel', exclude: /node_modules/ },
            { test: /\.(glsl|frag|vert)$/, loader: 'raw' },
            { test: /\.(glsl|frag|vert)$/, loader: 'glslify' },
        ],
    },
}

then it works as expected. Any idea why that might be?

'glslify!raw' should be 'raw!glslify'.
Multiple loaders applied from bottom to up order. Documentation should be fixed...

Hey, i have an unknown issue when using webpack and glslify :

ERROR in ./~/kenburns-webgl/src/index.js
Module not found: Error: Cannot resolve module 'glslify' in /Users/juju/Documents/projects/diaporama1/node_modules/kenburns-webgl/src
 @ ./~/kenburns-webgl/src/index.js 1:14-32
webpack: bundle is now VALID.

any idea what could go wrong ?

Hello, @trusktr and @revolunet. Sorry for the delay.

Can you try #15 and let me know if it works for you?

Thanks!
