|

|
|
Trim the whitespace within an array of GLSL tokens provided by [glsl-tokenizer](https://github.com/stackgl/glsl-tokenizer). Useful for minimising shader source size, especially after heavy processing steps such as seen in [glslify](http://github.com/stackgl/glslify) or as part of a GLSL minifier.

## Usage
|
||
|
|
|
||
|
|
[](https://www.npmjs.com/package/glsl-token-whitespace-trim)
|
||
|
|
|
||
|
|
### `trim(tokens, [all])`
|
||
|
|
|
||
|
|
Trims the whitespace in an array of GLSL `tokens`. By default, this will trim repeated to newlines such that no more than two newlines will appear in a row.
|
||
|
|
|
||
|
|
If you're more concerned about size than aesthetics, you can pass `true` as the second argument to remove *all* extraneous whitespace (more or less).
|
||
|
|
|
||
|
|
``` javascript
|
||
|
|
const tokenize = require('glsl-tokenizer')
|
||
|
|
const string = require('glsl-token-string')
|
||
|
|
const trim = require('glsl-token-whitespace-trim')
|
||
|
|
const fs = require('fs')
|
||
|
|
|
||
|
|
const src = fs.readFileSync('shader.glsl', 'utf8')
|
||
|
|
const tokens = tokenize(src)
|
||
|
|
|
||
|
|
trim(tokens, true)
|
||
|
|
|
||
|
|
const trimmed = string(tokens)
|
||
|
|
```
