Include What You Use
Include What You Use est un optimiseur d'inclusions C++ et un analyseur de dépendances d'en-têtes. Il identifie les inclusions d'en-têtes inutilisées ou manquantes dans les fichiers sources pour réduire l'encombrement du projet et améliorer les performances de compilation.
L'outil effectue une analyse statique en utilisant un arbre de syntaxe abstraite basé sur Clang pour mapper l'utilisation des symboles et suivre les effets du préprocesseur à travers différentes configurations de build. Il peut réécrire automatiquement les fichiers sources en insérant ou supprimant des directives de préprocesseur basées sur le graphe de dépendances calculé.
Le système s'intègre aux bases de données de compilation pour déterminer les flags de compilation exacts utilisés pour chaque fichier source, permettant l'analyse et l'élagage des dépendances à travers un projet entier.
Features
- Header Dependency Analysis - Provides specialized analysis to identify redundant or missing header inclusions to optimize C++ compilation times.
- Recursive Include Optimization - Reduces project bloat and compilation times by optimizing recursive include paths and pruning unused headers.
- AST-Based Source Transformations - Implements AST-based source transformations to automatically insert or delete preprocessor directives in source files.
- C++ Build Optimization - Optimizes C++ build performance by reducing compilation overhead through the pruning of unnecessary header includes.
- Header - Ensures every source file includes exactly the headers it needs for correct compilation without redundancy.
- Symbol Usage Tracking - Maps every identifier in a file against declarations provided by included headers to track symbol usage.
- C++ Header Optimizers - Identifies and removes unused header files to reduce project bloat and accelerate compilation speeds.
- Preprocessors - Tracks C-family preprocessor macros and conditional compilation to ensure accurate dependency analysis across build configurations.
- Compiler-Integrated AST Parsing - Utilizes the Clang compiler frontend to parse source code into an abstract syntax tree for precise symbol tracking.
- Build System Integration - Connects the analysis engine to compilers and compilation databases to automate project-wide header optimization.
- Automated Fixers - Automatically applies programmatic corrections to source files by adding or removing include directives based on static analysis.
- Compilation Database Integrations - Integrates with JSON compilation databases to determine the exact compiler flags used for every source file.
- Automated Code Fixes - Provides a command-line interface to automatically apply source code edits that fix missing or unused includes.
- Static Analysis - Uses the Clang toolset for static analysis of source code patterns to manage header dependencies.
- Systèmes de build - A tool to identify and fix unnecessary header inclusions.
- Outils de développement - Tool to analyze includes in source files
- Outils de développement - Identify and fix unnecessary header inclusions.
- Static Analysis - Analyzes include files to optimize build times and dependencies.
- Windows Environments - Listed in the “Windows Environments” section of the Awesome C awesome list.
