TClient

A simple BitTorrent client in Go.

Getting started

This client is pretty small & simple, however it has been structured to use minimal dependencies and follows a standard pattern to make the code easier to read.

There are a couple of things needed to get started.

1. Go 1.18

Instructions on installing Go 1.18 can be found in the link provided.

Pretty much that's it :)

Now, download dependencies with:

make install

Usage

The options available are:

Usage:
  -input string
        Input file
  -output string
        Where to download the file (default "./")

You can build the application and run it or run it directly with:

go run cmd/cli/main.go -input <TORRENT_FILE_PATH> -output <TORRENT_FILE_OUTPUT>

<TORRENT_FILE_PATH> is the file path of the torrent file, <TORRENT_FILE_OUTPUT> is the output path that you intend the file to be downloaded to.

For example:

go run cmd/cli/main.go -input debian-11.4.0-amd64-netinst.iso.torrent -output debian.iso

Optionally, you can build the application

make build
# or
go build -o <OUTPUT_PATH> cmd/cli/main.go

This will build the application in the bin directory. If you use the second option to build the application, you can specify the <OUTPUT_PATH> directory.

Once done, you can use the binary as well:

tclient -input debian-10.2.0-amd64-netinst.iso.torrent -output debian.iso

This assumes the binary built is called tclient

Tests

Tests have been written for the source code and can be validated with running:

make test
# or
go test ./...

Linting

Linting can be done using golanci-lint and setup is as below:

make setup-linting

Now run linting with:

make lint

Other commands can be found in the Makefile.

Limitations

• Only supports .torrent files (no magnet links)
• Only supports HTTP trackers
• Does not support multi-file torrents
• Strictly leeches (does not support uploading pieces)
