shader_debugger_core 1.0.0

Pure-Dart core of the Flutter shader debugger: a GLSL type model, symbol table and probe-shader instrumenter for Flutter fragment shaders.

1.0.0

First release.

• analyzeShader(): lexer, preprocessor (conditionals, macros with ##, includes), parser and resolver for Flutter's GLSL subset. Never throws: problems become diagnostics, and statements it does not understand are not pickable.
• Data model: GlslType (with the parts a picker can select: matrix columns, array elements, struct fields), SymbolTable / Scope / GlslSymbol, StatementInfo (writes, the parts written, variables in scope) and ShaderAnalysis.
• instrument(): turns a selection into a probe shader for heatmaps and exact pixel reads.
• package:shader_debugger_core/protocol.dart: the names shared by the runtime and the DevTools extension (protocol version 5).
