Learn how Clang's Sema component produces clear C++20 concept diagnostics, including fix-it hints, and see a worked example that shows what to expect from recent LLVM versions.
Learn how to integrate the lightweight "sema" npm package into your Node.js projects to control concurrency, throttle outbound requests, and prevent resource exhaustion. This guide covers setup, usage patterns, runtime checks, and recovery strategies.
When Clang emits a 'format %s expects char * but int' warning, this guide walks you through identifying the culprit, checking the format string against arguments, and applying the right fix.
Learn how adding a small set of structured tags to every pull‑request comment in Sema turns free‑form feedback into measurable data that can guide process improvements.
Learn how to onboard repositories to Sema using a phased approach, focusing on scoped access and noise reduction to ensure effective code analytics.
Learn how to use Go’s x/sync/semaphore to enforce a strict concurrency limit on a shared resource. The guide covers requirements, minimal design, trust boundaries, operational checks, failure modes, and when to redesign.
Discover how Clang’s semantic analyzer evaluates C++20 concepts, integrates constraint expressions, and performs partial ordering for overload resolution. A step‑by‑step example shows the AST nodes, compile‑time diagnostics, and practical limits to watch for.
When multiple threads race for a limited resource, a counting semaphore can enforce a safe cap. This post walks through a producer‑consumer example, shows how to configure fairness, and highlights pitfalls like permit leaks.
Enable Sema's SARIF output to feed static analysis results into GitHub Code Scanning, GitLab SAST, and IDEs. Covers CLI flags, sema.yaml config, a complete GitHub Actions workflow, schema version pitfalls, large-file handling, and a verification checklist.
