code-analyze-core

Core library for code structure analysis using tree-sitter.

Features

• Directory analysis - File tree with LOC, function, and class counts
• File analysis - Functions, classes, and imports with signatures and line ranges
• Symbol call graphs - Callers and callees across a directory with configurable depth
• Module index - Lightweight function and import index (~75% smaller than full file analysis)
• Multi-language - Rust, Python, TypeScript, TSX, Go, Java, Fortran, JavaScript, C/C++, C#
• Pagination - Cursor-based pagination for large outputs
• Caching - LRU cache for parsed results with mtime-based invalidation
• Parallel - Rayon-based parallel file analysis

Installation

Add to your Cargo.toml:

[dependencies]
code-analyze-core = "0.2"

Example

use code_analyze_core::{analyze_directory, analyze_file, AnalysisConfig};
use anyhow::Result;

#[tokio::main]
async fn main() -> Result<()> {
    // Analyze a directory (depth 2, compact summary)
    let output = analyze_directory("src/", Some(2), true, None, None, false, false).await?;
    println!("{}", output.formatted);

    // Analyze a single file
    let output = analyze_file("src/lib.rs", false, None, None, false, false, None, None).await?;
    println!("{}", output.formatted);

    Ok(())
}

Supported Languages

Configuration

AnalysisConfig provides resource limits for library consumers:

use code_analyze_core::AnalysisConfig;

let config = AnalysisConfig {
    max_file_bytes: Some(1_000_000), // skip files > 1 MB
    parse_timeout_micros: None,      // reserved, no-op in 0.2
    cache_capacity: None,            // use default LRU capacity
};
