hyper-jump

hyper-jump is a small, cross-platform version manager for a fixed set of command-line tools. it downloads release binaries, installs them under the hyper-jump data dir and gives you a single command to manage versions.

this project is intentionally narrow. it does one job and keeps the surface area small.

motivation

the goal is a small, predictable tool for a handful of binaries that ship on github releases. nix pkgs, homebrew and friends are fine for stable apps, but they tend to lag behind upstream tags and keeping overlays or waiting for packaging updates adds overhead.

the usual setup effort adds friction: nix's steep learning curve, inconsistent idioms and rough discoverability, plus brew's dependency resolution churn, disk bloat and periodic support or sudo friction on older macs. a single binary plus a private data dir stays out of the way.

nix packages were intentionally skipped because they pull users into a full ecosystem with its own workflows, which is more ceremony than this problem needed. even if you like nix, it's a hard sell for teams who just want a binary to exist and a version to be pinned without retraining or extra concepts. hyper-jump keeps versions side by side, pulls directly from upstream releases and lets you switch instantly without touching system state.

what it is

• a practical version manager for the supported packages listed below
• built for daily use rather than general-purpose plugin ecosystems
• a single cli with explicit subcommands and predictable paths

what it is not

• a universal version manager for arbitrary tools
• a long-running background service
• a plugin framework

installation

cargo install hyper-jump

configuration

make sure the install directory is on your PATH.

export PATH="$(hj prefix):$PATH"

on macos, you can also set the user path once:

sudo launchctl config user path "$(hj prefix):${PATH}"

usage

run hj --help if you can't remember the subcommands.

quick start

hj list-remote reth
hj install reth v1.10.2
hj use reth v1.10.2
hj list reth

commands

• hj install <package> <version|latest> install a version
• hj use <package> <version|latest> switch to a version and mark it as used
• hj list <package> show installed versions
• hj list-remote <package> show remote versions
• hj uninstall <package> <version> remove a version
• hj erase remove all installed versions
• hj prefix print the bin dir used for shims

notes

• version accepts tags like v1.10.2 or latest
• --output-format json|table or HYPER_JUMP_OUTPUT_FORMAT changes list output format
• --root-dir <path> or HYPER_JUMP_ROOT_DIR overrides the data dir
• HYPER_JUMP_PACKAGES_FILE points to a custom packages.toml
• make sure the path from hj prefix is on your PATH or nothing will run

supported packages

these come from packages.toml. by default the binary uses the embedded list, or you can drop a file at <root_dir>/packages.toml to override it.
