Cppfront - traduire du C++ expérimental en C+…

cppfront est un frontend d'extension de langage C++ et un traducteur source-à-source. Il fonctionne comme un transformateur de syntaxe qui convertit les extensions de langage expérimentales en code C++ conforme aux normes, permettant le prototypage de nouvelles fonctionnalités linguistiques au sein des systèmes de build existants.

Le projet fournit une couche de traduction qui ajoute la prise en charge de la correspondance de motifs (pattern matching), des contrats et de l'interpolation de chaînes. Il inclut un outil de métaprogrammation pour la réflexion à la compilation et la génération de code automatisée utilisant des métafonctions spécialisées.

Le système automatise plusieurs tâches de développement, notamment la résolution de l'ordre des dépendances via des déclarations anticipées automatiques et la gestion des modes de passage des paramètres. Il applique également une analyse statique pour insérer une vérification automatique des limites et optimiser la gestion des ressources en appliquant la sémantique de mouvement (move semantics) au dernier point d'utilisation d'une variable.

L'outil inclut un mécanisme de vérification pour garantir que le code source standard reste inchangé pendant le processus de traduction afin d'éviter les régressions de syntaxe.

Features

Language Prototyping Toolkits - Enables experimentation with new C++ syntax and features by translating them into standard compliant code.
Experimental Syntax Support - Converts experimental source code into standard syntax to enable new features within existing build systems.
Mixed Syntax Parsers - Handles source files containing both standard and experimental syntax within a single compilation unit.
Compile-Time Metafunctions - Ships a metaprogramming tool that uses compile-time reflection and specialized metafunctions for automated code generation.
Language Extension Transformers - Translates experimental C++ language extensions into standard compliant code via a syntax transformation pipeline.
Language Extension Frontends - Provides a translation layer that adds support for pattern matching, contracts, and string interpolation to C++.
Pattern Matching - Translates high-level pattern matching expressions into standard C++ conditional logic.
Compile-Time Meta-Programming - Enables compile-time reflection and automated code generation using specialized C++ metafunctions.
C++ Source-to-Source Translators - Converts experimental C++ syntax into standard C++ code to enable prototyping of new language features.
Metafunction Code Generators - Implements a system for compile-time reflection and automated code generation using specialized C++ metafunctions.
Compile-Time Metaprogramming - Provides a reflection system to execute metafunctions for introspection and automated code generation during compilation.
Source-to-Source Translation - Implements a multi-pass source-to-source translation pipeline to convert experimental extensions into standard compliant C++ code.
Automated Memory Optimizations - Automatically applies move semantics and bounds checking to reduce memory overhead and prevent errors.
Automatic Move Semantics Optimization - Automatically applies move semantics to variables at their last point of use to optimize resource management.
Embedded Regular Expression Syntax - Provides specialized syntax to embed regular expression logic directly into the language for more efficient validation.
Forward Declarations - Provides automatic generation of forward declarations to eliminate the need for specific definition ordering in source files.
Parameter Passing Constraints - Automates the selection between value and reference passing using standardized parameter modes.
Software Contract Systems - Introduces specialized syntax for defining preconditions and postconditions to ensure software correctness through contracts.
String Interpolation - Adds support for embedding expressions into string literals using simplified syntax for automated value capture and formatting.
Syntax Automation Layers - Simplifies development by automating forward declarations and managing parameter passing modes through a translation layer.
Syntax Transformers - Automates forward declarations and applies move semantics to optimize resource management.
Runtime Bounds Checking - Automatically inserts runtime checks on container subscript accesses to prevent out-of-bounds memory errors.
Declaration Order Resolution - Automatically generates forward declarations so functions and types work regardless of their definition order.
Instrumentation Generators - Automatically inserts bounds checking and move semantics based on static analysis of container sizes and variable lifetimes.

c3c is the compiler for the C3 programming language, transforming source code into executable binaries, static libraries, or dynamic libraries using an LLVM backend. It implements a system based on result-based error handling, scoped memory pooling, and a semantic macro system. The compiler provides first-class support for hardware-backed SIMD vectors that map directly to processor instructions and enables runtime polymorphism through interface-based dynamic dispatch. The project covers a broad set of low-level capabilities, including manual and pooled memory management, inline assembly inte
