Periphery

Periphery este un instrument de analiză statică și detectare a codului mort (dead code) pentru proiecte Swift. Acesta identifică clasele, structurile, funcțiile și proprietățile neutilizate și servește drept optimizator de suprafață API pentru a găsi declarațiile publice care pot fi restricționate la acces intern.

Instrumentul include scanare specializată pentru fișierele Interface Builder, cum ar fi storyboard-urile și XIB-urile, pentru a se asigura că membrii conectați la UI nu sunt marcați incorect ca neutilizați. De asemenea, oferă eliminarea automată a codului pentru a șterge codul mort identificat și parametrii neutilizați direct din fișierele sursă.

Capabilitățile sale de analiză acoperă detectarea protocoalelor redundante, a cazurilor de enum neutilizate, a importurilor inutile și a proprietăților care sunt doar atribuite. Sistemul gestionează datoria tehnică prin filtrarea bazată pe baseline și suportă proiecte în limbaje mixte, păstrând simbolurile expuse către runtime-ul Objective-C.

Periphery se integrează cu sistemele de build și pipeline-urile CI folosind configurații bazate pe YAML și poate exporta rezultatele analizei în mai multe formate standard din industrie.

Features

Dead Code Cleanup - Statically analyzes Swift projects to identify unreferenced classes, structs, functions, and properties.
Call Graph Traversals - Identifies unreferenced symbols by building and traversing a dependency graph of declarations and their call sites.
Unused Code Identification - Uses binary index store data to identify unused code without requiring a full project rebuild.
Swift Linters - Provides static analysis of Swift project graphs to find redundant declarations and unused imports.
Compiler Index Store Integration - Processes binary index stores from the Swift compiler to efficiently determine symbol usage.
Interface Builder Parsing - Scans Storyboard and XIB files to ensure UI-connected members are not incorrectly flagged as unused.
Redundant Accessibility Detection - Identifies declarations marked public that are never referenced from outside their home module.
Accessibility Level Analysis - Swift Unused Code Detector identifies public declarations that can be made private because they are only used internally.
API Surface Reduction - Identifies public declarations that can be restricted to internal access to optimize the module's API surface.
Dead Code Removal - Automatically removes identified dead code and unused parameters directly from Swift source files.
Interface Builder Analyzers - Parses XIB and storyboard files to ensure UI-connected members are not incorrectly flagged as unused.
Mixed-Language Project Support - Retains declarations accessible to the runtime to prevent false positives in multi-language codebases.
Assign-Only Property Detection - Identifies properties that are assigned values but never read, including those in structs with synthesized initializers.
Redundant Protocol Detection - Identifies protocols that are conformed to but never used as existential types or for generic specialization.
Runtime Interop Analysis - Preserves symbols exposed to the Objective-C runtime to prevent false positives in mixed-language projects.
Synthesized Code Handling - Preserves properties on types with compiler-generated code to avoid marking synthesized members as unused.
Unused Enum Case Detection - Identifies individual cases within non-raw-representable enumerations that are never referenced.
Unused Import Detection - Identifies import statements that are not required by any declaration in the source file.
Unused Parameter Detection - Identifies parameters in functions, protocols, and overridden methods that are never accessed.
Baseline-Based Debt Management - Provides a mechanism to track known unused code in a baseline file to isolate new regressions from legacy debt.
General Utilities - Identifies unused code in Swift projects.

Vulture is a static analysis tool and linter designed to find unused variables, functions, and classes in Python source code. It operates as a dead code detector and unused code finder that scans source files to identify unreachable expressions and imports without executing the code. The tool employs a confidence-based heuristic scoring system to assign probability values to detections, helping to distinguish truly unused symbols from potential false positives. It further assists in pruning dead logic by sorting detected unused classes and functions by line count to prioritize the removal of
