+
+"Descope" an array of GLSL tokens such that they can be safely inlined alongside
+within another shader without causing any global variable conflicts.
+
+Useful for modularising GLSL source files, e.g. as is done in
+[glslify](http://github.com/stackgl/glslify), but should be useful in other
+tools too.
+
+Written with WebGL's GLSL syntax in mind – all the same, pull requests to
+support other variants would be much appreciated :)
+
+## Usage
+
+[![NPM](https://nodei.co/npm/glsl-token-descope.png)](https://nodei.co/npm/glsl-token-descope/)
+
+### `descope(tokens, [rename(name)])`
+
+Takes an array of GLSL `tokens` produced by
+[glsl-tokenizer](http://github.com/stackgl/glsl-tokenizer) and renames variables
+to avoid global conflicts by modifying their "data" property in-place.
+
+For example:
+
+``` javascript
+var tokenize  = require('glsl-tokenizer/string')
+var descope   = require('glsl-token-descope')
+var stringify = require('glsl-token-string')
+
+var src = `
+precision mediump float;
+
+uniform mat4  top1;
+uniform float top2;
+
+void main() {
+  float x = 1.0;
+  gl_FragColor = vec4(vec3(x), top2);
+}
+`.trim()
+
+var tokens = tokenize(src)
+
+console.log(stringify(descope(tokens)))
+```
+
+Which should rename `main`, `top1` and `top2` to result in this output:
+
+``` glsl
+precision mediump float;
+
+uniform mat4  top1_0;
+uniform float top2_1;
+
+void main_2() {
+  float x = 1.0;
+  gl_FragColor = vec4(vec3(x), top2_1);
+}
+```
+
+Optionally, you may pass in a custom `rename` function as `descope`'s second
+argument to choose how you rename your variables. For example, adding a custom
+`rename` function to the previous function:
+
+``` javascript
+descope(tokens, function(name) {
+  return 'a_' + name
+})
+```
+
+Would result in the following shader:
+
+``` glsl
+precision mediump float;
+
+uniform mat4  a_top1;
+uniform float a_top2;
+
+void a_main() {
+  float x = 1.0;
+  gl_FragColor = vec4(vec3(x), a_top2);
+}
+```
