Gozelle

Gozelle is a lightning-fast and minimal smart cd command written in Go — inspired by zoxide. Jump to frequently used directories with just a keyword, powered by frecency scoring, fuzzy matching, and shell integration.

Features

• Frecency Scoring — jump history is ranked by frequency and recency
• Fuzzy Matching — jump with just a keyword or part of a directory name
• Smart Ranking — most relevant paths surface first
• Manual Add — add directories to the index yourself
• Query Mode — list matching directories without jumping
• Compact Storage — gob-encoded data stored locally
• Shell Integration — Bash and Zsh command-line hooks for seamless tracking

Requirements

• Bash, Zsh, or Fish shell
• Gozelle binary in your $PATH
• go version 1.24+
• fzf installed for interactive mode

Platform Support Notice:

Gozelle has currently only been tested and verified on Linux systems. While it may work on other Unix-like OSes or Windows, no official support or testing has been done outside of Linux.

Quick Start

Option 1: Build from Source

git clone https://github.com/atliod/gozelle
cd gozelle
go build -o gozelle .
sudo mv gozelle /usr/local/bin/

/usr/local/bin can be replace by any directory in your $PATH

Option 2: Use go install

go install github.com/atliod/gozelle@latest

Make sure your $GOPATH/bin is in your $PATH (commonly ~/go/bin):

export PATH="$PATH:$(go env GOPATH)/bin"

Add to Shell Startup File

For Bash:

echo 'eval "$(gozelle init bash)"' >> ~/.bashrc
source ~/.bashrc

For Zsh:

echo 'eval "$(gozelle init zsh)"' >> ~/.zshrc
source ~/.zshrc

For Fish:

echo 'gozelle init fish | source' >> ~/.config/fish/config.fish
source ~/.config/fish/config.fish

Usage

Jump to a Directory

gz projects       # jumps to the best match (e.g., ~/Documents/School/Programming/projects)

Show Matching Directories (without jumping)

gozelle query projects

Add a Directory Manually

gozelle add /some/path/to/add

Interactive Mode

Environment Variables

Variable	Description	Default
GOZELLE_ECHO	Whether to print the target directory path to stdout after jumping. Must be "true" or "false".	"false" (default)
GOZELLE_DATA_DIR	Path to the directory where Gozelle stores its data file (db.gob). If not set, defaults to: $XDG_DATA_HOME/gozelle/db.gob or <home>/.local/share/gozelle/db.gob if $XDG_DATA_HOME is unset.	~/.local/share/gozelle/db.gob (default)

Notes

• GOZELLE_ECHO must be set to exactly "true" or "false". Any other value will reset it to "false" and print a warning.
• When GOZELLE_DATA_DIR is set to a non-existent directory, Gozelle will attempt to create the directory automatically in the uses default data directory. ~/.local/share in linux)
• The environment variable GOZELLE_DATA_DIR refers to a directory; the actual data file is stored inside it as db.gob.

Example usage

export GOZELLE_ECHO=true
export GOZELLE_DATA_DIR="$HOME/.config/gozelle"

---

How It Works

• Enables shell hooks for automatic logging via init bash or init zsh
• Tracks every visited directory using the shell hook
• Stores them in a gob-encoded file under your user data directory (default is ~/.local/share/Gozelle for Linux users)
• Finds all matches for keywords entered, e.g., gz keywords
• Ranks them using a frecency score (frequency + recency)
• Uses fzf to provide an interactive selection UI when requested

Motivation

This project was a hands-on learning opportunity for:

• Concurrency — handling simultaneous updates and queries efficiently
• Worker Pools — to process background updates to scoring
• Mutexes — for safe access to shared resources (like the gob database)
• Command Line Hooks — shell integration and behavior injection
• Gob Encoding — simple and efficient binary data serialization in Go
• Integration with External Tools — incorporating fzf for interactive mode

Roadmap

• Zsh support
• Fish shell support
• Interactive fzf-style selector
• Configurable data file location
• Directory expiration / pruning logic
• Man Page
• Completion support
• Better pruning logic
• Higher weight to paths where the keyword is closer to the end
