🐟 Fish Shell Configuration

My personal config.fish setup, optimized for productivity, aesthetics, and speed.

---

🎨 Theme: Catppuccin Mocha

This configuration uses the Catppuccin Mocha palette for syntax highlighting and terminal UI elements.

• Primary Colors: Blue (89b4fa) for commands, Green (a6e3a1) for quotes.
• Backgrounds: Custom selection and search match backgrounds for high visibility.

🛠️ Environment Variables

• Terminal: kitty
• Editor: nvim (Neovim)
• Visual: nvim

🚀 Key Features

Smart Path Management

Includes a custom add_path function that ensures directories are added to your $PATH uniquely, preventing duplicate entries during shell restarts.

• Adds ~/.opencode/bin
• Adds ~/.local/bin

Better Navigation & Tools

• Zoxide: Replaces standard cd with z (smarter navigation).
• Eza: Replaces ls with modern icons and tree views.
• Gum: Integrated for better reading/writing experiences in the terminal.
• Yazi: Terminal file manager integration.

Double-Escape Sudo

A handy keybinding that allows you to prepend sudo to your current command just by pressing ESC twice.

⌨️ Abbreviations & Aliases

I use Fish Abbreviations (abbr) instead of standard aliases so that the full command is expanded in the history.

Abbr	Command	Description
v	nvim	Open Neovim
ls	eza --icons	Modern list files
ll	eza --long --icons	Detailed list
..	cd ..	Go up one directory
y	yazi	File manager
fs	fastfetch	System info
:q	exit	Quit shell (Vim style)

Git Workflow

• go: git init
• gs: git status
• gi: git add .
• gc: git commit -m
• gp: git push -u origin
• gcl: git clone
