shinkansen-cli 1.0.7

Fast, reliable anime downloader for AnimePahe - built with lessons from autopahe

🚅 Shinkansen - Anime Downloader (anime-pahe-dl)

A blazing-fast, fully interactive terminal application for downloading anime.

Shinkansen is a powerful Terminal User Interface (TUI) that lets you search and batch-download anime directly from AnimePahe. It natively bypasses Cloudflare, fetches episodes in true parallel, and features an elegant interactive full-width menu right in your terminal.

---

Quick Start (1-Command Install)

For the absolute easiest setup across Mac/Linux/Windows, install the tool globally in its own isolated environment using pipx (the modern standard for Python CLIs):

# Safely install globally using the official PyPI release (Zero Configuration!)
pipx install shinkansen-cli

🎮 Usage

Interactive Mode (Recommended)

Simply type the root command anywhere in your terminal to launch the pure TUI experience:

shinkansen

This launches a beautiful, dynamically-rendered menu offering Search & Download, Library browsing, History tracking, and recursive Settings management—all fully navigable via your arrow keys!

Optional: aria2c (for faster multi-connection downloads)

For accelerated downloads with multiple connections, install aria2:

• macOS: brew install aria2
• Ubuntu/Debian: sudo apt install aria2
• Windows: winget install aria2

Then set it as your download backend:

shinkansen config set download_backend aria2c

Features

• HTTP-first approach -- tries direct API calls before launching a browser, for speed
• Cloudflare bypass -- Playwright fallback when Cloudflare blocks HTTP requests
• Persistent cookie caching -- saves Cloudflare session cookies to disk (~/.shinkansen/cookies.json) so subsequent runs skip the challenge entirely (25-min TTL)
• Parallel batch downloads -- spawns multiple Playwright browser instances (prepare_workers, default 3) to prepare episodes in true parallel, with a separate download thread pool (max_downloads, default 5); 200 episodes drops from ~5 hours to ~2 hours
• Pipelined downloading -- each episode's download starts the moment it's resolved, overlapping Playwright prep with file I/O
• Multiple quality options -- select 360p, 480p, 720p, 1080p, best, or worst
• Sub/Dub preference -- choose between Japanese audio with subtitles or English dub
• Download resume -- partial downloads are resumed automatically via HTTP Range headers
• Episode ranges -- download specific episodes (--range 1-12), comma-separated (--range 1,3,5-7), or all ( --all)
• Download history -- tracks every download with anime name, episode, quality, and date
• Anime library -- browse and search your downloaded collection
• Config system -- persistent settings at ~/.shinkansen/config.json (default quality, output dir, folder creation, etc.)
• Interactive TUI -- run shinkansen to access a beautiful arrow-key navigable main menu routing your entire application
• Automatic Retries -- any episodes that timeout or fail directly prompt you to instantly retry them at the end of the batch
• Rich terminal UI -- Claude-style split screen welcome banners, colored output, live progress bars, tables, and spinners
• File size preview -- view episode sizes before downloading
• Smart download skipping -- warns about already-downloaded episodes without re-downloading
• Graceful shutdown -- Ctrl+C cleanly stops workers while finishing active downloads

Architecture

AnimePahe API (JSON)
    |
    v
AnimePaheClient (client.py)
    - HTTP-first with Playwright fallback
    - Cookie caching for Cloudflare sessions
    - Paginated episode fetching
    |
    v
Downloader (downloader.py)
    - animepahe.si/.com/.org -> kwik.cx/kwik.si -> direct .mp4 URL
    - Split into prepare() + download_prepared() for pipelining
    - Resume support via Range headers
    - Pluggable backends: requests (default) or aria2c
    |
    v
WorkerPool (worker_pool.py)
    - N PrepareWorkers (own Playwright browser + thread each)
    - Download ThreadPoolExecutor (bounded by max_downloads)
    - Cookie sharing: Worker 0 clears Cloudflare, others load cached cookies
    - Rich Live progress display
    |
    v
CLI (cli.py)
    - Click commands with Rich output
    - History and library management

🤝 Contributing & New Anime Sources

We want to grow! Shinkansen currently supports downloading directly from AnimePahe, but our goal is to build a massive ecosystem supporting multiple anime sources.

We highly encourage the open-source community to get involved:

• Suggest new anime sites to support by opening an Issue.
• Fork the repository and open Pull Requests implementing new fetchers/extractors.
• Improve the interactive TUI or squash bugs.

Please read our CONTRIBUTING.md guidelines to easily get started. Let's build the ultimate anime CLI together!
