Intermodal: A 40' shipping container for the Internet

Intermodal is a user-friendly and featureful command-line BitTorrent metainfo utility. The binary is called imdl and runs on Linux, Windows, and macOS.

At the moment, creation, viewing, and verification of .torrent files is supported. See the book for examples and usage information.

For more about the project and its goals, check out this post.

Installation

Supported Operating Systems

imdl supports Linux, MacOS, and Windows, and should work on other unix OSes. If it does not, please open an issue!

Packages

Operating System	Package Manager	Package	Command
Various	Cargo	imdl	cargo install imdl
Arch Linux	Yay	intermodal-binAUR	yay -S intermodal-bin
Arch Linux	Yay	intermodalAUR	yay -S intermodal
Arch Linux	Manual Installation	intermodalAUR	wiki

Pre-built binaries

Pre-built binaries for Linux, macOS, and Windows can be found on the releases page.

You can use the following command to download the latest binary for Linux, MacOS, or Windows, just replace DEST with the directory where you'd like to install the imdl binary:

curl --proto '=https' --tlsv1.2 -sSf https://imdl.io/install.sh | bash -s -- --to DEST

A good place to install personal binaries is ~/bin, which install.sh uses when --to is not supplied. To create the ~/bin directory and install imdl there, do:

curl --proto '=https' --tlsv1.2 -sSf https://imdl.io/install.sh | bash

Additionally, you'll have to add ~/bin to the PATH environment variable, which the system uses to find executables. How to do this depends on the shell.

For sh, bash, and zsh, it should be done in ~/.profile:

echo 'export PATH=$HOME/bin:$PATH' >> ~/.profile

For fish, it should be done in ~/.config/fish/config.fish:

echo 'set -gx PATH ~/bin $PATH' >> ~/.config/fish/config.fish

Cargo

imdl is written in Rust and can be built from source and installed with cargo install imdl. To get Rust, use the rustup installer.

Shell Completion Scripts

Shell completion scripts for Bash, Zsh, Fish, PowerShell, and Elvish are available in the completions directory, included in all binary releases.

For Bash, move imdl.bash to $XDG_CONFIG_HOME/bash_completion or /etc/bash_completion.d/.

For Fish, move imdl.fish to $HOME/.config/fish/completions/.

For the Z shell, move _imdl to one of your $fpath directories.

For PowerShell, add . _imdl.ps1 to your PowerShell profile (note the leading period). If the _imdl.ps1 file is not on your PATH, do . /path/to/_imdl.ps1 instead.

The imdl binary can also generate the same completion scripts at runtime, using the completions command:

$ imdl completions --shell bash > imdl.bash

The --dir argument can be used to write a completion script into a directory with a filename that's appropriate for the shell. For example, the following command will write the Z shell completion script to $fpath[0]/_imdl:

$ imdl completions --shell zsh --dir $fpath[0]

Chat

The primary chat is on Discord, but I try to also check Keybase and IRC as time permits.

Contributing

Your bug reports, feature requests, pull requests, and design help are much appreciated!

Check out issues with the "good first issue" label for some ideas.

Quite a few files are generated by the program in bin/gen. Some files are generated from templates, so those templates should be edited to make changes to those files:

• bin/gen/templates/SUMMARY.md -> book/src/SUMMARY.md
• bin/gen/templates/README.md -> README.md
• bin/gen/templates/introduction.md -> book/src/introduction.md

Some files are completely generated, and so shouldn't be manually edited at all:

• CHANGELOG.md
• book/src/commands/*
• completions/*
• man/*

All files can be regenerated by running cargo run --package gen all, or just gen, if you have just installed.

The changelog is generated from YAML metadata in commit messages. Here is an example commit message, with metadata:

Upgrade foo

Upgrade foo to v7.5, which is much better.

type: changed
pr:
- https://github.com/casey/intermodal/pull/1
fixes:
- https://github.com/intermodal/issues/2
- https://github.com/intermodal/issues/3

The only required field is type. To see the possible values for type, run cargo run --package gen commit-types.

Semantic Versioning

Intermodal follows semantic versioning.

In particular:

• v0.0.X: Breaking changes may be introduced at any time.
• v0.X.Y: Breaking changes may only be introduced with a minor version number bump.
• vX.Y.Z: Breaking changes may only be introduced with a major version number bump

Unstable Features

To avoid premature stabilization and excessive version churn, unstable features are unavailable unless the --unstable / -u flag is passed, for example imdl --unstable torrent create .. Unstable features may be changed or removed at any time.

Source Signatures

All commits to the intermodal master branch signed with Casey Rodarmor's PGP key with fingerprint 3259DAEDB29636B0E2025A70556186B153EC6FE0, which can be found on keybase and on his homepage.
