Determine the scope depth of an array of GLSL tokens

Package Exports

  • glsl-token-depth

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (glsl-token-depth) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

glsl-token-depth

experimental

Determine the scope depth of an array of GLSL tokens.

Useful for inferring the scope of variables in a GLSL shader without having to fully parse the source.

Usage

NPM

depth(tokens)

Where tokens is an array of tokens returned from glsl-tokenizer. Each token will be modified in-place, and given a depth property.

var tokenize = require('glsl-tokenizer/string')
var depth    = require('glsl-token-depth')
var fs       = require('fs')

var src = fs.readFileSync('shader.frag', 'utf8')
var tokens = tokenize(src)

depth(tokens)

tokens[0].depth // 0
tokens[1].depth // 0
tokens[2].depth // 0
tokens[3].depth // 0
tokens[4].depth // 1
// ...
