🚀 Quick Start Example

use ebook_rs::{Book, ReflowPaginator, Cfi};

fn main() -> Result<(), String> {
    // Auto-detects and opens EPUB, MOBI, AZW3, FB2, KEPUB, LIT, or CBZ files
    let mut book = Book::from_file("book.epub")?;

    println!("Title: {}", book.metadata().title);
    println!("Sections: {}", book.spine().len());

    // Search with surrounding context snippets and <mark> highlights
    let search_results = book.search("quantum");
    for res in search_results {
        println!("Snippet: {}", res.snippet);
    }

    // Resolve CFI element step to CSS DOM selector
    let cfi = Cfi::parse("epubcfi(/6/4[chap01]!/4/2/1:10)")?;
    let section = book.get_section(0)?;
    if let Some(target) = cfi.resolve_dom_path(&section.raw_html) {
        println!("CSS Selector: {}", target.css_selector);
        println!("Target Element ID: {:?}", target.element_id);
    }

    Ok(())
}

🆕 What's New in v0.7.0

  • Regex Full-Text Search — Search eBook text using full regular expression patterns (book.search_regex("(?i)quantum|physics")).
  • EPUB Structural Validator — Validate eBook package integrity, OPF metadata, and spine references with book.validate() (EpubValidator).
  • Book Fingerprinting & Deduplication — Generate metadata-independent content hashes to detect duplicate books across formats with book.fingerprint().
  • Academic Citation Exporter — Instantly export scholarly citations in BibTeX, APA, MLA, and Chicago formats (book.to_bibtex(), book.to_apa(), book.to_mla(), book.to_chicago()).
use ebook_rs::Book;

let book = Book::from_file("book.epub")?;

// 1. Regex Search
let matches = book.search_regex("(?i)alice|rabbit")?;

// 2. Structural Validation
let report = book.validate();
if !report.is_valid {
    println!("Validation errors: {:?}", report.errors);
}

// 3. Content Fingerprinting & Match Score
let fp = book.fingerprint();
println!("Content Hash: {}", fp.content_hash);

// 4. Academic Citations
println!("BibTeX:\n{}", book.to_bibtex());
println!("APA: {}", book.to_apa());
