# 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. ## Table of Contents - [Overview](#overview) - [Documentation](#documentation) - [Installation](#installation) - [Personalization](#personalization) - [Minimal Mode](#minimal-mode) - [Attribution](#attribution) - [License](#license) --- ## Overview This config layers on top of the CachyOS base Fish configuration and adds: - **Catppuccin Mocha** theming throughout (prompt, FZF, syntax highlighting) - **Starship** prompt with VI key bindings - **Fisher** plugin manager bootstrapped automatically; manages `sponge` (failed-command history filter); FZF bindings, Catppuccin theme, done, autopair, and puffer-fish are bundled directly with the config as customized versions - **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 Antigravity session management - **WakaTime** shell activity tracking - **Opt-out toggles** for every opinionated component β€” see [Minimal Mode](#minimal-mode) --- ## Documentation ### [πŸ“– Full Documentation Wiki](docs/wiki/index.md) A multi-page Markdown wiki auto-generated from the single source file `docs/fish-config.md` on every push to `main`. It covers configuration variables, key bindings, abbreviations, all functions, the dependency catalog, customization, and more. To browse the docs from the terminal: | Command | Description | |---|---| | `help config` | Open the terminal manual in the best available pager | | `help config ` | Jump directly to a section matching the keyword | | `help config --html` | Open the pre-built HTML docs in the default browser | | `help config --html` | Open HTML docs at the matching section anchor | | `help config --man` | Open the compiled man page via `man -l` | | `help config --man` | Open the man page jumping to the nearest match | The pager falls back through: **ov** β†’ **bat** β†’ **man -l** β†’ **less** β†’ **cat**. > **Note:** `fish-config` (hyphen) is this configuration's man page. `fish_config` (underscore) is fish's built-in browser-based configuration tool β€” a completely separate command. Don't mix them up. --- ## 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 β€” Fisher will be installed automatically on first launch and the Catppuccin Mocha theme will be applied. All plugin functionality is bundled directly with this config and requires no additional installation. A [chezmoi](https://www.chezmoi.io/) dotfile manager is also configured β€” secrets are sourced from `~/.config/.user-dots/fish/secrets.fish` and excluded from version control. > [!IMPORTANT] > `config.fish` ends with a `return` sentinel guard. Any lines appended **after** it by a tool's setup command will silently have no effect. Many tools (starship, zoxide, mise, etc.) offer a setup command that appends an `init | source` line to your `config.fish` β€” all integrations are managed through `conf.d/` files instead. If you add a new tool and its shell integration appears to do nothing, check whether its setup command appended an init line to the bottom of `config.fish` and create a `conf.d/.fish` file for it instead. ### Updating the Config Pull the latest changes from upstream without needing a configured git remote: | Command | Description | |---|---| | `config-update` | Fetch and apply the latest commits from upstream | | `config-update --dry-run` | Preview available changes without applying them | | `config-update --force` | Stash local changes, pull, then restore the stash | --- ## 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/ β”œβ”€β”€ 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 β€” things that would break or be wrong on any other system. ```fish # ~/.config/.user-dots/fish/local.fish # CDPATH β€” directories searched by cd set -gx CDPATH . /home/youruser/projects /home/youruser # Path to your shared .gitignore boilerplate (used by `gi -b` / `gi` default) set -gx GITIGNORE_BOILERPLATE ~/.config/git/gitignore_boilerplate ### 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 $HOME/.config/.user-dots/fish/local.fish end ``` `fish_variables` (which fish auto-manages and may contain universal variable state) is excluded from this repo via `.gitignore`. --- ## Minimal Mode Everything opinionated in this config β€” command shadows, startup side-effects, key and environment overrides, terminal integrations, and logging β€” is active by default but can be switched off with universal variables. Five category toggles and one master switch are available: | Variable | Disables | |---|---| | `__fish_config_op_aliases` | Command shadows: `ls`β†’eza, `cat`β†’bat, `cd`β†’zoxide, `rm`β†’trash, `top`β†’btop, and friends; `grep`/`cp`/`mv`/`wget` flag injection | | `__fish_config_op_autoexec` | Startup side-effects: Fisher bootstrap, theme apply, `paru`/`yay` wrapper generation, auto venv activation, WakaTime hook | | `__fish_config_op_overrides` | Vi mode, `exit`β†’`smart_exit`, `$PAGER`/`$MANPAGER`/`$CDPATH`, bang-bang history expansion, autopair, puffer, Starship prompt, theme colors | | `__fish_config_op_integrations` | Kitty/WezTerm window abbreviations, `done` notifications, `spwin`/`tab`/`split`, `hist`, `logs`, `upgrade`, WakaTime | | `__fish_config_op_logging` | Scrollback capture on exit, `paru`/`yay` AUR log wrappers, Kitty watcher capture (sentinel-file coordinated) | | `__fish_config_opinionated` | Master switch β€” all five categories at once | Set any of them to a falsy value (`0`, `false`, `no`, `off`, `n`) to disable; erase the variable to re-enable: ```fish # Plain shell: disable everything opinionated set -U __fish_config_opinionated 0 # Or pick a single category, e.g. keep integrations but drop command shadows set -U __fish_config_op_aliases off # Back to full flavor set -Ue __fish_config_opinionated ``` Command shadows react immediately; bindings, prompt, and abbreviations take effect in new shells. With aliases disabled, `rm` deletes permanently again instead of trashing. See `help config opinionated` for the full component list. --- ## Attribution The core of the [Zoxide integration](docs/wiki/2-path-setup.md) in this repository was originally adapted from the [icezyclon/zoxide.fish](https://github.com/icezyclon/zoxide.fish) plugin (MIT Licensed) and has since been heavily customized for performance and Fish 4.x compatibility. --- ## License Copyright (C) 2026 Rootiest This project is licensed under the **GNU Affero General Public License v3.0 or later** (AGPLv3+).
