Arborist v0.1.3

Added

• New Built with AI · Powered by StrayMark section in README acknowledging
  the project's AI-assisted development process and its use of
  StrayMark — a CLI for cognitive discipline in
  AI-assisted engineering — for decision tracking and governance.
• New Copyright section in README identifying Strange Days Tech S.A.S. de
  C.V. (strangedays.tech) as the original author
  and intellectual-property holder.
• SPDX-License-Identifier: MIT OR Apache-2.0 header with copyright
  attribution on every Rust source file in the library, in line with Rust
  ecosystem conventions.

Arborist v0.1.2

Fixed

• Move exclude list from [lib] to [package] in Cargo.toml, reducing published
  crate size from 1.2 MiB (287 files) to 242 KiB (138 files).

Arborist v0.1.1

Changed

• Restructure Feature Flags section in README: move before Installation, expand with
  per-language table showing feature flag, tier, and tree-sitter crate mapping.
• Add Default column to Supported Languages table (Yes / Opt-in).
• Add [package.metadata.docs.rs] with all-features = true so docs.rs renders
  documentation for all 12 languages.
• Add actionable doc comment on LanguageNotEnabled error with Cargo.toml fix examples.
• Add module-level documentation to src/languages/mod.rs explaining the feature gate
  system and tier structure.

Arborist v0.1.0

Arborist v0.1.0

Multi-language code complexity metrics powered by tree-sitter.

Computes cognitive complexity (SonarSource), cyclomatic complexity (McCabe), and source lines of code (SLOC) for functions and methods — all from a single, embeddable Rust library.

Supported Languages (12)

Tier	Languages	Feature flags
Tier 1 (default: ★)	Rust★, Python★, JavaScript★, TypeScript★, Java★, Go★, C#, C++, C, PHP	default = 6 most popular
Tier 2	Kotlin, Swift	kotlin, swift

features = ["all"] enables all 12 languages.

Highlights

• SonarSource-compliant cognitive complexity: nesting penalties, boolean operator sequences, flat else-if, lambda nesting, recursive call detection
• McCabe cyclomatic complexity: per-arm counting for match/switch constructs
• Feature-gated compilation: only compile the grammars you need
• JSON serialization: FileReport and FunctionMetrics implement Serialize/Deserialize
• Configurable thresholds: flag functions exceeding a cognitive complexity limit
• 177 tests across all languages, clippy clean

Installation

[dependencies]
arborist = "0.1"                    # default: Rust, Python, JS, TS, Java, Go
arborist = { version = "0.1", features = ["all"] }  # all 12 languages

Quick Example

use arborist::{analyze_file, FileReport};

let report: FileReport = analyze_file("src/main.rs")?;
for func in &report.functions {
    println!("{}: cognitive={}, cyclomatic={}, sloc={}",
        func.name, func.cognitive, func.cyclomatic, func.sloc);
}

Known Limitations

• Recursion detection is not supported for Kotlin and Swift (their tree-sitter grammars lack a named field on call expression nodes)
• Halstead metrics are planned for v0.2.0
