About This Tool

WGSL analyzer for Neovim provides static analysis for WGSL shaders within the Neovim editor, surfacing syntax errors, semantic problems, and basic performance concerns before you run on the GPU.
Conceptually, it tokenizes source code, builds an AST, resolves symbols, and applies type rules to verify correctness. It can also validate resource bindings against a manifest and emit targeted suggestions to fix issues.
Who benefits: graphics programmers, engine developers, and teams seeking rapid feedback during shader development. Unique value: tight integration with Neovim workflows, deterministic diagnostics, and optional cross-file checks that go beyond single-file linting.
Core features include grammar-based parsing, location-aware diagnostics, optional binding validation against a manifest, and simple optimization hints. Use cases include early error detection, code refactoring safety, and performance-oriented shader improvements.

Frequently Asked Questions

Find Quick Answers

What issues does the WGSL Analyzer Neovim detect?

It detects syntax errors, undefined identifiers, type mismatches in vectors and matrices, incorrect binding usage, and basic compatibility warnings with shader stages. It also flags potential code smells that may affect readability or correctness.

Can it analyze multi-file projects?

Yes, if provided with a project context or binding manifest, the analyzer can resolve cross-file references and verify bindings across files, offering cohesive diagnostics rather than isolated file results.

Does it require network access?

No external network dependency is required for analysis; it performs parsing, AST construction, symbol resolution, and rule checks locally, ensuring privacy and consistent results without server calls.

What are the outputs?

Diagnostics include severity, location, message, and suggested fixes; an optional AST excerpt helps tooling; performance hints may indicate optimization opportunities. Outputs are structured for easy consumption by editors and CI pipelines.
