A jscpd release is one Rust workspace published under several names. Everything lives under rust/; rust/scripts/sync-version.mjs keeps the versions below in step (the engine version comes from rust/package.json).
Path: rust/crates/cpd
crates.io: jscpd
Version: 5.4.0
The CLI. cargo install jscpd installs two identical binaries, jscpd and cpd. Its library target is internal (test helpers only); depend on the crates below for programmatic use. See Rust docs.
Path: rust/crates/cpd-core
crates.io: cpd-core
Version: 0.1.20
Core data models and the Rabin-Karp rolling hash implementation.
Path: rust/crates/cpd-tokenizer
crates.io: cpd-tokenizer
Version: 0.1.19
Source code tokenizer (224 formats, listed in FORMATS.md). Uses oxc_parser for JavaScript/TypeScript/JSX and per-block tokenization for Vue SFC, Svelte, Astro, and Markdown. Pure — no filesystem or network access (enforced in CI).
Path: rust/crates/cpd-finder
crates.io: cpd-finder
Version: 0.1.20
File walking, orchestration, baseline handling, and git blame. Uses rayon for parallelism, ignore + globset for file matching. The entry point for the Rust API.
Path: rust/crates/cpd-reporter
crates.io: cpd-reporter
Version: 0.1.21
Output format rendering for the 15 reporters.
Path: rust/crates/cpd-semantic
crates.io: cpd-semantic
Version: 0.1.1
Semantic clones (--semantic, experimental): function extraction for the languages --similarity does not parse (Rust, Python, and tree-sitter grammars for C, C++, C#, Go, Java, Kotlin, PHP, Ruby, Scala and Swift), code embeddings from CodeRankEmbed or jina-embeddings-v2-base-code run in-process with candle or taken from an OpenAI-compatible API, the thresholds calibrated for nine models, a vector cache, and the pairing rule. It plugs into the finder as a clone pass (cpd_finder::pass::ClonePass), so the other crates build without its dependencies. Unlike the crates above, it reads and writes the user cache directory and makes network calls: the model download and the embeddings API.
All npm packages share the engine version (5.4.0). None of them needs a Node.js runtime to run jscpd — Node.js is only the delivery mechanism.
Path: rust/jscpd
npm: jscpd
Installs the jscpd command. A thin launcher that resolves the platform package below for the current OS/CPU and executes the binary.
Path: rust
npm: cpd
Installs the cpd command. Same launcher, same binary, shorter name.
Path: rust/npm/<package>
Each contains one prebuilt binary and is pulled in as an optional dependency of jscpd and cpd; npm installs only the one matching the host.
