This release includes a rewrite to the AST parser and generator, with minor fixes to the tokenizer and minifier (note this will be rewritten once WGSL AST is implemented #21).

Both GLSL and WGSL are supported by the tokenizer and minifier, but only GLSL is supported so far by the parser and generator (#20).

This enables code modification and reflection of GLSL programs, although a visitor API does not yet exist, and AST nodes must be manually recursed.

import { type Program, parse, generate } from 'shaderkit'

// https://github.com/CodyJasonBennett/shaderkit#ast
const program: Program = parse(glsl)

// optionally reflect program here (e.g. collect all global uniforms)
const uniforms: string[] = []
for (const node of program.body) {
  if (node.type === 'VariableDeclaration') {
    for (const declaration of node.declarations) {
      if (declaration.qualifiers.includes('uniform') {
        uniforms.push(declaration.id.name)
      }
    }
  }
}

// optionally modify program here (e.g. remove version header)
if (program.body[0].type === 'PreprocessorStatement') program.body.shift()

// Compile back into GLSL
const output: string = generate(program, { target: 'GLSL' })
