Module duplicates 

Code duplication / clone detection module.

This module implements suffix array + LCP based clone detection for TypeScript/JavaScript source files. It supports multiple detection modes from strict (exact matches only) to semantic (structure-aware matching that ignores identifier names and literal values).

Modules

detect

Suffix Array + LCP based clone detection engine.

families

Clone family grouping and refactoring suggestion generation.

normalize

token_types

Token type definitions for clone detection tokenization.

tokenize

Structs

CloneFamily

A clone family: a set of clone groups that share the same file set.

CloneGroup

A group of code clones – the same (or normalized-equivalent) code appearing in multiple places.

CloneInstance

A single instance of duplicated code at a specific location.

DefaultIgnoreSkipCount

Number of files skipped by one built-in duplicates ignore pattern.

DefaultIgnoreSkips

Human-format-only skipped-file stats for built-in duplicates ignores.

DuplicatesConfig

Configuration for code duplication detection.

DuplicationReport

Overall duplication analysis report.

DuplicationStats

Aggregate duplication statistics.

MirroredDirectory

A detected mirrored directory pattern: two directory prefixes that contain identical files (e.g., src/ and deno/lib/).

RefactoringSuggestion

A refactoring suggestion for a clone family.

Enums

DetectionMode

Detection mode controlling how aggressively tokens are normalized.

RefactoringKind

The kind of refactoring suggested for a clone family.

Constants

DUPES_DEFAULT_IGNORES

Built-in duplicates ignores for generated framework and tool output.

Functions

find_duplicates

Run duplication detection on the given files.

find_duplicates_cached

Run duplication detection with the persistent token cache enabled.

find_duplicates_cached_with_default_ignore_skips

Run cached duplication detection and return human-format sidecar metadata for files skipped by built-in duplicates ignores.

find_duplicates_in_project

Run duplication detection on a project directory using auto-discovered files.

find_duplicates_touching_files

Run duplication detection and only return clone groups touching focus_files.

find_duplicates_touching_files_cached

Run focused duplication detection with the persistent token cache enabled.

find_duplicates_touching_files_cached_with_default_ignore_skips

Run cached focused duplication detection and return human-format sidecar metadata for files skipped by built-in duplicates ignores.

find_duplicates_touching_files_with_default_ignore_skips

Run focused duplication detection and return human-format sidecar metadata for files skipped by built-in duplicates ignores.

find_duplicates_with_default_ignore_skips

Run duplication detection and return human-format sidecar metadata for files skipped by built-in duplicates ignores.
