Hopper

A Minecraft package manager for the terminal.

Hopper can automatically search, download, and update Minecraft mods, modpacks, resource packs, and plugins from Modrinth so that keeping your mods up-to-date and compatible with each other is easy. With Hopper, you won't have to manually visit CurseForge and download each mod one-by-one every time you set up a new instance, or deal with the hassle of swapping out different mod versions for hours while trying to get Minecraft to accept them all at once.

Hopper is still very early in development, but important features are coming along smoothly, and we'll have lots of progress to show off in the coming weeks. It's written in Rust and released under the AGPLv3.

We're looking for people to help contribute code and write documentation. Please reach out to us in our Discord "server" if you're interested in helping out. If you have a taste in CLI apps like Hopper, your input is especially appreciated.

Inspired by applications like paru, a feature-packed AUR helper and topgrade, a tool to upgrade everything

Hopfile Structure

Hopfiles will contain a Minecraft version number, a list of packages, and any references to other hopfiles on which it's based, or "templates". If a hopfile is based on other template hopfiles, it inherits the packages from them. A hopfile does not inherit the package or Minecraft version from a template.

template = "example-template"
mc-version = "1.19.2"

[packages]
fabric-mod = [ "sodium", "lithium" ]
resource = "alacrity"

Hopper Configuration File Structure

Hopper's configuration will be maintained with a list of all hopfiles known to hopper. Its config file will also contain a list of mod hosting sites like Modrinth and CurseForge and a list of (remote or local) version-control repositories from which to compile mods. The latter will use a (potentially custom) build file format to be defined at a later date.

hopfiles = [
  "~/.minecraft/mods/template.hop",
  "~/.minecraft/1.91.1/mods/1.19.1.hop" 
]

Usage

hopper [options...] [subcommand...]

OPTIONS

-v, --verbose

Searches for packages, displays the results, and downloads any selected packages to the local cache. If multiple targets are specified, results are displayed in order of specification.

OPTIONS

-d, --dir [directory...]

Specifies the directory to download to (default is "$XDG_CACHE_HOME"/hopper/).

-m, --mc-version [version...]

Specifies for what version of Minecraft packages are being retrieved.

-n, --no-confirm

Does not display search results and downloads exact matches to the cache. Requires --mc-version and --type be specified.

-t, --type [types...]

Specifies what types of packages are being queried.

init [options...]

Creates a hopfile in the current directory and adds it to the global known hopfiles list.

OPTIONS

-d, --dir [directory...]

Specifies the directory in which the hopfile is being created.

-f, --hopfile [hopfiles...]

Specifies templates upon which to base the new hopfile.

-m, --mc-version [version]

Specifies for what version of Minecraft packages are being managed.

-t, --type [type...]

Specifies what type of packages will be listed in this hopfile.

install [options...] [packages...]

Adds packages to the current hopfile, symlinking them to its directory. If the package cannot be found in the package cache, hopper get is run first.

update [options...]

Updates installed packages and adds mods if they're missing to directories with known hopfiles.
