KGet! v1.5.3 (Latest Release)

A modern, lightweight, and versatile downloader written in Rust for fast and reliable file downloads via command line (CLI) and graphical user interface (GUI).

How It Works (Summary)

1. Progress Bar (CLI): Shows speed, ETA, and transferred bytes.
2. Smart File Naming:
   • Uses the filename from the URL.
   • Defaults to index.html if the URL ends with /.
3. Error Handling: Exits with code 1 on HTTP errors (e.g., 404).
4. Space Check: Verifies available disk space.
5. Automatic Retry: Retries download on network failure.
6. ISO Smart Detection: Detects .iso files to ensure raw binary transfer and prevent corruption.
7. Integrity Check: Optional SHA256 verification for disk images after download.
8. Memory Efficient: Parallel downloads use streaming buffers to maintain a low RAM footprint regardless of file size.
9. Disk Optimization: Uses buffered I/O to prevent high disk active time and system freezes during fast transfers.
10. Advanced Download Mode (HTTP/HTTPS): Downloads in parallel chunks, supports resume.
11. Proxy Support: HTTP, HTTPS, SOCKS5 with authentication.
12. Optimization Features: Compression (for cache), file caching, speed limiting.
13. Torrent Downloads (Magnet Links):
    • Default: opens the magnet link using your system's default BitTorrent client (qBittorrent/Transmission/etc).
    • Optional (feature): can download via Transmission RPC (torrent-transmission feature).
14. FTP/SFTP Downloads: Connects to FTP/SFTP servers to transfer files.

Optional Cargo features

GUI (gui)

Build/run with GUI support:

cargo build --features gui
cargo run --features gui -- --gui

Transmission RPC torrent backend (torrent-transmission)

If you want KGet to add magnet links to a Transmission daemon (RPC), build with:

cargo build --features torrent-transmission
# or with GUI:
cargo build --features "gui torrent-transmission"

Select the backend at runtime:

• Default (no env var): uses the system torrent client (xdg-open/open/start)
• Transmission RPC:

# Linux/macOS
export KGET_TORRENT_BACKEND=transmission

# Windows PowerShell (current session)
$env:KGET_TORRENT_BACKEND="transmission"

Transmission settings (env vars):

• KGET_TRANSMISSION_HOST (default: localhost)
• KGET_TRANSMISSION_PORT (default: 9091)
• KGET_TRANSMISSION_RPC_PATH (default: /transmission/rpc)
• KGET_TRANSMISSION_WEB_PATH (default: /transmission/web/)
• Optional auth: KGET_TRANSMISSION_USER, KGET_TRANSMISSION_PASS

Compatibility:

• You can also use KGET_TRANSMISSION_URL and KGET_TRANSMISSION_WEB (full URLs).

Installation

Option 1: Compile from source

You will need Rust installed. If you don't have it, install it from rustup.rs.

Install some dependencies: For Debian/Ubuntu based systems:

sudo apt update
sudo apt install -y libxcb-render0-dev libxcb-shape0-dev libxcb-xfixes0-dev libxkbcommon-dev libssl-dev pkg-config

For Fedora:

sudo dnf install -y libxcb-devel libxkbcommon-devel openssl-devel pkg-config

Clone the repository and compile the project:

git clone https://github.com/davimf721/KGet.git
cd KGet
cargo build --release

The executable will be in target/release/kget. You can copy it to a directory in your PATH:

sudo cp target/release/kget /usr/local/bin/

Option 2: Install via Cargo

You can install the published binary from crates.io (the GUI and Transmission backend are opt-in via features):

# Install the binary without GUI (default)
cargo install Kget

# Install with GUI support
cargo install Kget --features gui

# Install with Transmission RPC backend (optional)
cargo install Kget --features torrent-transmission

# Install with both
cargo install Kget --features "gui torrent-transmission"

If you encounter issues with the GUI when installing via cargo install, compiling from source is more reliable.

Option 3: Download Pre-compiled Binaries

Check the Releases section for the latest binaries for your OS.

Linux/macOS:

chmod +x ksget  # Make executable
./kelpsget [URL]    # Run directly

Windows:

Run the .exe file directly.

Usage

Command Line (CLI)

kget [OPTIONS] <URL>

Examples:

• HTTP/HTTPS Download:

  kget https://example.com/file.txt
  

• Rename Output File:

  kget -O new_name.txt https://example.com/file.txt
  kget -O ~/MyDownloads/ https://example.com/video.mp4 # Saves as ~/MyDownloads/video.mp4
  

• FTP Download:

  kget ftp://user:password@ftp.example.com/archive.zip
  kget --ftp ftp://ftp.example.com/pub/file.txt
  

• SFTP Download: (Requires SSH key setup or password if the server allows it)

  kget sftp://user@sftp.example.com/path/file.dat
  kget --sftp sftp://user@sftp.example.com/path/file.dat -O local.dat
  

• Torrent Download (Magnet Link): (Requires transmission-daemon configured and running)

  kget "magnet:?xt=urn:btih:YOUR_HASH_HERE&dn=TorrentName"
  kget --torrent "magnet:?xt=urn:btih:YOUR_HASH_HERE" -O ~/MyTorrents/
  

  KelpsGet will add the torrent to Transmission and attempt to open the web interface (http://localhost:9091) for management.

• Silent Mode:

  kget -q https://example.com/file.txt
  

• Advanced Download Mode (HTTP/HTTPS):

  kget -a https://example.com/large_file.zip
  

  • ISO Download with Verification: KGet will automatically detect the ISO and ask if you want to verify the SHA256 hash once finished.

• Use Proxy:

  kget -p http://proxy:8080 https://example.com/file.txt
  

• Proxy with Authentication:

  kget -p http://proxy:8080 --proxy-user user --proxy-pass pass https://example.com/file.txt
  

• Speed Limit:

  kget -l 1048576 https://example.com/file.txt  # Limit to 1MB/s
  

• Disable Compression (KGet-specific, not HTTP):

  kget --no-compress https://example.com/file.txt
  

• Disable Cache (KGet-specific):

  kget --no-cache https://example.com/file.txt
