Crate glsl

GLSL compiler

This crate is a GLSL450 compiler. It’s able to parse valid GLSL450 formatted source into an abstract syntax tree (AST). That AST can then be transformed into SPIR-V, your own format or even folded back to a raw GLSL String (think of a minifier, for instance).

You’ll find two main modules:

• parser, which exports most of the parsers to parse the whole or a part of GLSL source (intermediary parsers)
• syntax, which exports the AST

Feel free to inspect those modules for further information.

Quick parsing

If you’re just looking for a parser that would give you the AST for a shader, you might be interested in translation_unit.
