Range V3

Il s'agit d'une bibliothèque de plages C++ et d'une extension de la Standard Template Library qui fournit une collection d'algorithmes composables et de vues paresseuses pour traiter des séquences de données. Elle fonctionne comme un framework de traitement de séquence paresseux et une bibliothèque de métaprogrammation de modèles pour manipuler des listes de types et effectuer des calculs de type à la compilation.

Le projet permet des modèles de programmation fonctionnelle en C++ grâce à l'utilisation de la syntaxe de pipe et de l'application partielle pour créer des chaînes de transformation de données lisibles, de gauche à droite. Il permet la construction de pipelines de données paresseux qui filtrent et transforment les éléments à la demande pour réduire la surcharge mémoire et éviter les copies inutiles.

La bibliothèque couvre de larges domaines de capacité, y compris la manipulation de séquences, la manipulation de types à la compilation et l'implémentation de types de plage et d'itérateurs personnalisés. Elle fournit des outils pour la mutation de conteneurs sur place, la répartition d'algorithmes basée sur la projection et la gestion de listes de types via une série d'appelables au niveau du type.

  • Sequence Transformations - Implements a comprehensive set of algorithms for mapping and transforming data sequences to optimize memory and processing.
  • Data Sequence Manipulation - Enables transforming, filtering, and processing sequences of data without manual iterator management.
  • Sequence Transformation Chains - Links multiple range adaptations using pipe syntax to process sequences in a readable chain.

  • Sequence Algorithms - Implements standardized sequence algorithms with a unified interface for both iterator pairs and range objects.
  • Range Algorithms - Provides generic algorithms for sorting, searching, and transforming data collections using range-based logic.
  • Sentinel-Based Iteration - Terminates algorithms using a sentinel type instead of a closing iterator to allow for predicate-based boundaries.
  • STL Extensions - Extends the C++ Standard Template Library with range-based overloads and concept-based constraints.
  • Type-Level Functional Programming - Performs computations and logical operations on types using callables and lists at compile time.
  • Type List Management - Stores and manipulates sequences of types using compile-time operations like push, pop, concat, and join.
  • Range Adaptation Pipelines - Enables the construction of readable, left-to-right data transformation chains using pipe syntax.
  • Compile-Time Concept Validation - Enforces compile-time type requirements on functions and templates using a concepts emulation layer.
  • Lazy Sequence Processing - Implements a framework for building data pipelines that transform and filter elements on demand without full memory allocation.
  • Projection-Based Dispatch - Transforms elements through a projection mapping function before they are processed by an algorithm's core logic.
  • Eager Mutation Pipelines - Allows modifying containers in-place through a chain of operations that return the container for subsequent processing.
  • Variable In-Place Mutations - Provides algorithms to modify container contents in-place and return the container for subsequent operations.
  • Composable Type Computations - Combines multiple type-level callables into a single operation where the output of one computation flows into the next.
  • Eager Container Mutations - Applies algorithms to containers in-place to mutate data and return the container for further processing.
  • Eager Sequence Mutations - Modifies containers in-place through a chain of eager operations such as sorting and shuffling.
  • Partial Application - Provides utilities to create new callables by pre-filling a subset of original function arguments.
  • Higher-Order Algorithm Constraints - Ensures predicates and projections are compatible with all permutations of an iterator's value and reference types.
  • Inline Type Lambdas - Specifies type-level callables in place using a lambda-like syntax for immediate use in computations.
  • Type List Element Access - Retrieves types from compile-time lists by position, index, or by accessing the front and back elements.
  • Custom Range Adaptors - Enables the creation of custom range types and iterators to integrate user-defined data structures with standard range algorithms.
  • Custom Range Implementation - Allows implementing user-defined ranges and views using facades or adaptors for integration with standard algorithms.
  • Custom Iterators - Allows the creation of compatible random-access or proxy iterators to control sequence traversal and element access.
  • Type Callables - Creates reusable type-level computations that can be passed as arguments to other algorithms or composed together.
  • Type-Level Boolean Logic - Evaluates boolean-like logical conditions such as and, or, and not across different types at compile time.
  • Type Sequence Conversions - Transforms diverse type sequences, such as tuples or index sequences, into a standardized list format.
  • Range - Simplifies the creation of custom ranges by providing a base class for deriving iterator and sentinel types.
  • Algorithm Projections - Provides projection functions that allow algorithms to operate on specific members of complex data types.
  • General Utilities - Experimental range library for C++11/14/17.
  • Extensions de la bibliothèque standard - Range library for modern C++.
