[releases]

Jump integrates with your shell and learns about your navigational habits by keeping track of the directories you visit. It gives you the most visited directory for the shortest search term you type.

Installation

Jump comes in packages for the following platforms.

Platform	Command
macOS	brew install jump or port install jump
Linux	sudo snap install jump
Nix	nix-env -iA nixpkgs.jump
Go	go install github.com/gsamokovarov/jump@latest

Linux distribution specific packages

Distribution	Command
Void	xbps-install -S jump
Ubuntu	wget https://github.com/gsamokovarov/jump/releases/download/v0.51.0/jump_0.51.0_amd64.deb && sudo dpkg -i jump_0.51.0_amd64.deb
Debian	wget https://github.com/gsamokovarov/jump/releases/download/v0.51.0/jump_0.51.0_amd64.deb && sudo dpkg -i jump_0.51.0_amd64.deb
Fedora	wget https://github.com/gsamokovarov/jump/releases/download/v0.51.0/jump-0.51.0-1.x86_64.rpm && sudo rpm -i jump-0.51.0-1.x86_64.rpm

Integration

You are using Jump through its shell helper function, j. To get it, you have to integrate Jump with your shell.

bash / zsh

Add the line below in ~/.bashrc, ~/bash_profile or ~/.zshrc:

eval "$(jump shell)"

fish

Add the line below in ~/.config/fish/config.fish:

jump shell fish | source

PowerShell

Add the line below needs to your profile, located by typing $PROFILE:

Invoke-Expression (&jump shell pwsh | Out-String)

Once integrated, Jump will automatically monitor directory changes and start building an internal database.

Murex

Jump bindings can be installed directly from Murex:

murex-package install https://github.com/lmorg/murex-module-jump.git

Please note that this doesn't install jump itself. You will still need to install the jump executable using the installation instructions above.

But j is not my favorite letter!

This is fine, you can bind jump to z with the following integration command:

eval "$(jump shell --bind=z)"

Typing z dir would just work! This is only an example, you can bind it to anything. If you are one of those persons that likes to type a lot with their fingers, you can do:

eval "$(jump shell --bind=goto)"

Voila! goto dir becomes a thing. The possibilities are endless!

Usage

Once integrated, jump introduces the j helper. It accepts only search terms, and as a design goal, there are no arguments for j. Whatever you give it, it's treated as a search term.

Jump uses fuzzy matching to find the desired directory to jump to. This means that your search terms are patterns that match the desired directory approximately rather than exactly. Typing 2 to 5 consecutive characters of the directory name is all that jump needs to find it.

Regular jump

The default search behavior of jump is to match the directory name of a score. The match is case insensitive.

If you visit the directory /Users/genadi/Development/rails/web-console often, you can jump to it by:

$ j wc      # or...
$ j webc    # or...
$ j console # or...
$ j b-c     # or...

Using jump is all about saving keystrokes. However, if you made the effort to type a directory base name exactly, jump will try to find the exact match, rather than a fuzzy search.

$ j web-console
$ pwd
/Users/genadi/Development/rails/web-console

Deep jump

Given the following directories:

/Users/genadi/Development/society/website
/Users/genadi/Development/chaos/website

Typing j site matches only the base names of the directories. The base name of /Users/genadi/Development/society/website is website, the same as the other absolute path above. The jump above will land on the most-scored path, which is the society one, however, what if we wanted to land on the chaos website?

$ j ch site
$ pwd
/Users/genadi/Development/chaos/website

This instructs jump to look for a site match inside that is preceded by a ch match in the parent directory. The search is normalized only on the last two parts of the target paths. This will ensure a better match because of the shorter path to a fuzzy match.

There are no depth limitations, though and a jump to /Users/genadi/Development/society/website can look like this:

$ j dev soc web
$ pwd
/Users/genadi/Development/society/website

Every space passed to j is converted to an OS separator. The last search term can be expressed as:

$ j dev/soc/web
$ pwd
/Users/genadi/Development/society/website

Reverse jump

Bad jumps happen. Sometimes, we're looking for a directory that doesn't have the best score at the moment. Let's work with the following following jump database:

/Users/genadi/Development/society/website
/Users/genadi/Development/chaos/website
/Users/genadi/Development/hack/website

Typing j web would lead to:

$ j web
$ pwd
/Users/genadi/Development/society/website

If we didn't expect this result, instead of another search term, typing j without any arguments, will instruct jump to go to the second-best match.

$ j
$ pwd
/Users/genadi/Development/chaos/website

Case-sensitive jump

To trigger a case-sensitive search, use a term that has a capital letter.

$ j Dev
$ pwd
/Users/genadi/Development

The jump will resolve to /Users/genadi/Development even if there is /Users/genadi/Development/dev-tools that scores better.

Pins

For various reasons, Jump may not always find the directory you want, but don't worry—you can make it work!

A pin forces an input to always go to a specific location. If you want j r to always go to /Users/genadi/development/rails, you can do:

$ cd /Users/genadi/development/rails
$ jump pin r
$ cd
$ j r # Skips the scoring and goes straight to the pinned directory.
$ pwd
/Users/genadi/development/rails

Notice the jump command instead of the j shell function helper. j will always treat its input as search terms. It may apply some heuristics to how the input looks, but it will never accept arguments or switches. Here is where the jump command comes in. It is bundled with lots of helpers to make your j life easier. The pins are one of them.

Try jump --help for all those hidden (not not-documented ones) features.

Is it like autojump or z?

I was an avid autojump user, but it wasn't forgiving my sloppy fingers. That pushed me to create Jump with the goal of accepting fuzzy search terms. This lets you type a couple of letters and go to your project:

j web vs j website

The fuzzy typing is your fingers-friendly. You can make a typo, and the jump would mostly work:

j wwebsite

As a design goal, the j helper doesn't have any arguments. It's all about the search term. That said, you can use the search term itself to hint jump about the desired directory.

Typing mixed case input would force a case-sensitive match:

j Dev would prefer /Users/genadi/Development

If you have multiple projects with the same name in umbrella directories you can hint with OS separators:

j soc/web -> /society/website j ra/web -> /raketa/website

If your input doesn’t give you the right dir, you can j. That will jump to the next entry with the previous input.

Little hand-tuned details like those let jump read my mind with zero LLMs interaction. If I wasn't a humble developer, I'd call it artisan hard-crafted software, but I am, so I'll let you call it what you want. 😄

Migrate from autojump or z

You can import your datafile from autojump or z with:

$ jump import

This will try z first, then autojump, so you can even combine all the entries from both tools.

The command is safe to run on a pre-existing jump database, because if an entry exist in jump already, it won't be imported, and its score will remain unchanged. You can be explicit and choose to import autojump or z with:

$ jump import autojump
$ jump import z

Thanks! 🙌

Thank you for stopping by and showing your interest in Jump!
