TinyPreprocessor `v0.1.0` — Initial preview (2026-01-09)

A lightweight, extensible preprocessing library for .NET that resolves dependencies, merges resources, and generates source maps.

Recursive dependency resolution with cycle detection
Extensible pipeline: bring your own directive parser, resource resolver, and merge strategy
Source maps for tracing generated output back to original sources
Diagnostics-first design with “continue on error” support
Thread-safe concurrent ProcessAsync calls (isolated per-call state)

Core abstractions: ResourceId, IResource, IDirective, IDirectiveParser<TDirective>, IResourceResolver
Preprocessor orchestrator: Preprocessor<TDirective, TContext>.ProcessAsync(...)
Dependency graph: ResourceDependencyGraph (cycle detection + topological ordering)
Diagnostics: DiagnosticCollection + built-in diagnostics for common failure modes
Source mapping: SourceMap / SourceMapBuilder with query support
Default merge strategy: ConcatenatingMergeStrategy<TContext> (concatenation + directive stripping + line mappings)

dotnet add package TinyPreprocessor --version 0.1.0

DeduplicateIncludes is currently effectively always-on (resources are cached per call and won’t be merged multiple times, even if set to false).
If cycles are present, a circular-dependency diagnostic is emitted; merged output may be incomplete or not strictly dependency-correct.

See the docs folder in the repo: core abstractions, diagnostics, dependency graph, source mapping, merge system, and orchestrator design.
