Show HN: Canon-C – a semantic C library

**Show HN: Canon-C – a semantic C library**

I kept rewriting the same low-level patterns in C — arenas, memory management, error handling, vectors, parsing, file I/O, iteration utilities — and existing libraries either hide allocation, impose frameworks, or lack consistency.So I built Canon-C, a small, composable set of explicit C modules that:Treat C as an execution backend, not a semantic authorityAdd meaning through libraries, not syntaxMake intent visible directly in the API: ownership, lifetime, and failure handling are explicitModules are organized by semantic layers:core/ — memory, lifetime, scope, primitivessemantics/ — Option, Result, error handlingdata/ — vectors, queues, stacks, string buildersalgo/ — map, filter, fold, sort, searchutil/ — safe string ops, file I/O, logging, timingDesign highlights:Header-onlyNo runtime or global stateNo hidden allocation (except in clearly marked convenience layers)Fully explicit behaviorI’d love feedback from anyone doing systems programming, embedded C, or serious C projects, especially on macro-heavy vs. modular design, semantic clarity, and practical usage.
