# Fish Shell Configuration

A feature-rich Fish shell configuration for CachyOS (Arch Linux), built around a Catppuccin Mocha aesthetic with a curated set of modern CLI tool integrations, smart shell functions, and a heavily customized abbreviation system for keyboard-driven workflows.

## Overview

This config layers on top of the CachyOS base Fish configuration and adds:

- **Catppuccin Mocha** theming throughout (prompt, FZF, Zellij)
- **Starship** prompt with VI key bindings
- **Fisher** plugin management with FZF key bindings and Catppuccin syntax colors
- **Smart CLI wrappers** that prefer modern tools (`eza`, `bat`, `btop`, `dust`, `prettyping`) with graceful fallbacks
- **Auto Python venv** activation on directory change (direnv-aware)
- **Kitty terminal** deep integration for splits, tabs, and SSH
- **AI workflow** helpers for Claude and Gemini session management
- **WakaTime** shell activity tracking

## Plugins

Managed via [Fisher](https://github.com/jorgebucaran/fisher):

| Plugin | Purpose |
|---|---|
| `jorgebucaran/fisher` | Plugin manager |
| `patrickf1/fzf.fish` | FZF key bindings for history, files, processes, git |
| `catppuccin/fish` | Catppuccin Mocha syntax highlighting |

| `jorgebucaran/replay.fish` | Run bash commands in fish without losing state |
| `nickeb96/puffer-fish` | Expand `...` to `../..`, `!!` to last command, etc. |
| `mattmc3/magic-enter.fish` | Smart Enter: runs `ls` / `git status` on blank line |
| `jorgebucaran/spark.fish` | Sparkline bar charts in the terminal |

Install plugins after cloning:

```fish
fisher update
```

---

## Theme & Prompt

### Starship

The primary prompt is [Starship](https://starship.rs/), initialized in `config.fish`. Configure it via `~/.config/starship.toml`.

### FZF

FZF is themed to Catppuccin Mocha with the following colors set via `FZF_DEFAULT_OPTS`:

- Background: `#1E1E2E` / `#313244`
- Foreground: `#CDD6F4`
- Highlights: `#F38BA8` (red), `#CBA6F7` (mauve), `#B4BEFE` (lavender)

**Key bindings** (from `fzf.fish`):

| Binding | Action |
|---|---|
| `Ctrl+R` | Search command history |
| `Ctrl+F` | Search directory files |
| `Ctrl+Alt+F` | Search git-tracked files |
| `Ctrl+Alt+L` | Search git log |
| `Ctrl+Alt+S` | Search git status |
| `Ctrl+V` | Search shell variables |
| `Ctrl+Alt+P` | Search running processes |

---

## Integrations

### Zoxide

Smart `cd` replacement. `z <keyword>` jumps to the best frecency match; `zi` opens an interactive selector.

### DirEnv

Automatically loads `.envrc` files on directory change. Takes priority over the built-in auto-venv logic.

### Auto Python Venv

When entering a directory containing a `.venv/`, the virtualenv is automatically activated. It is deactivated when you leave the project tree. DirEnv-managed directories are skipped to avoid conflicts.

### WakaTime

Every shell command is reported to WakaTime for time-tracking. Disable by setting `FISH_WAKATIME_DISABLED=1`.

### Tailscale

Full tab completion for the `tailscale` CLI is provided via `conf.d/tailscale.fish`.

---

## Key Bindings

Beyond standard shell and FZF bindings, these custom interactive shortcuts are available:

| Binding | Action | Description |
|---|---|---|
| `Ctrl+G` | Previous Path Head | Behaves like `!$:h` in Bash. Inserts the directory part of the previous command's last argument. |
| `Ctrl+F` | Interactive History Substitution | Behaves like `!!:s/old/new/` in Bash. Performs substitution on the previous command using `old/new` syntax. When no text is entered, prepends `sudo` to the previous command. The `old/new/n` syntax will perform substitution on the command `n` lines previous in the history. |
| `Ctrl+Alt+U` | Replace Command Token | Strips the first token (the command) from the current line. **If the line is empty**, it pulls the previous command and strips its first token, placing the cursor at the start for a quick replacement (e.g., changing `mkdir` to `cd` while keeping the paths). |

---

## Functions

### Modern CLI Replacements

These functions wrap modern alternatives with graceful fallbacks to standard tools.

## Abbreviations

## Installation

This config is managed as a Git repository. To use it on a new machine:

```fish
# Back up any existing config
mv ~/.config/fish ~/.config/fish.bak

# Clone this repo
git clone https://git.rootiest.dev/rootiest/fish-config.git ~/.config/fish
```

Then open a new Fish shell — Fisher and all plugins will be installed automatically on first launch, and the Catppuccin Mocha theme will be applied.

A [chezmoi](https://www.chezmoi.io/) dotfile manager is also configured — secrets are sourced from `~/.config/.user-dots/fish/secrets.fish` and excluded from version control.

---

## Personalization

Sensitive credentials and machine-specific paths are kept out of version control via a secondary private directory at `~/.config/.user-dots/fish/`. Two files are sourced automatically by `config.fish` if they exist:

```
~/.config/.user-dots/fish/
├── secrets.fish   # API keys, tokens, passwords, personal identifiers
└── local.fish     # Machine-specific paths and environment variables
```

### secrets.fish

Use this file for anything you would not commit to a public repo: API keys, auth tokens, passwords, and personal identifiers like usernames or email addresses.

```fish
# ~/.config/.user-dots/fish/secrets.fish

### Identity ###
set -gx MY_NAME "Your Name"
set -gx MY_EMAIL "you@example.com"
set -gx GPG_RECIPIENT "you@example.com"

### API Keys & Tokens ###
set -gx GITHUB_TOKEN ghp_yourTokenHere
set -gx OPENAI_API_KEY sk-proj-yourKeyHere
set -gx GITEA_TOKEN yourGiteaTokenHere
set -gx GITEA_CHOSEN_LOGIN your.gitea.instance
set -gx TEA_LOGIN your.gitea.instance

### Backup ###
set -gx KOPIA_PASSWORD yourKopiaPassword
```

### local.fish

Use this file for paths and variables that are specific to one machine — things that would break or be wrong on any other system.

```fish
# ~/.config/.user-dots/fish/local.fish

# Project root for quick cd
set -gx cdp /home/youruser/projects

# CDPATH — directories searched by cd
set -gx CDPATH . /home/youruser/projects /home/youruser

### SSH ###
# Quick shortcuts to your own servers
abbr -a sshr 'ssh you@your-server.local'
abbr -a sshw 'ssh you@work-server.example.com'

### Docker contexts ###
# Named shortcuts for your own Docker contexts (docker context ls)
abbr -a dcr 'docker context use my-remote-server'
abbr -a dcw 'docker context use work-server'
```

### How it works

`config.fish` sources both files with an existence check so the public config works cleanly on any machine that doesn't have the private repo:

```fish
if test -f $HOME/.config/.user-dots/fish/secrets.fish
    source $HOME/.config/.user-dots/fish/secrets.fish
end

if test -f $HOME/.config/.user-dots/fish/local.fish
    source $HOME/.config/.user-dots/fish/local.fish
end
```

`fish_variables` (which fish auto-manages and may contain universal variable state) is excluded from this repo via `.gitignore`.
