Add Fish Alias

Create a new fish shell function/alias in Juliet dotfiles.

Process

1. Create function file

   symlinked/config/fish/functions/aliases/<name>.fish
   

2. Write the function

   function <name> --wraps "<wrapped-command>"
       <wrapped-command> $argv
   end
   

3. Reload fish (or open new terminal)

   source ~/.config/fish/config.fish
   

File Naming

• Filename = function name (e.g., g.fish defines g function)
• Use lowercase, hyphens for multi-word names
• Files are auto-loaded alphabetically

Patterns

Simple Wrapper

function g --wraps "git"
    git $argv
end

Wrapper with Auto-Install

function nv --wraps "neovide"
    if ! command -v neovide 2&> /dev/null
        gum confirm "Neovide not installed. Install?" && brew install --cask neovide
    end
    neovide $argv
end

Function with Subcommand Aliases

function pv --wraps "pipenv"
    switch $argv[1]
        case "i"
            set argv[1] install
    end
    pipenv $argv
end

Interactive Function (using gum)

function clone
    set -l provider (gum choose --header "Source?" github gitlab)
    # ... rest of logic
end

Multiple Functions in One File

Group related functions (e.g., git.fish contains ga, gl, gm, commit, etc.)

Conventions

• Use --wraps for tab completion inheritance
• Use $argv to pass all arguments
• Use gum for interactive prompts (confirm, choose, input, spin)
• Helper functions: log, error, debuglog (defined in fish config)

Common Mistakes

• Forgetting --wraps (loses tab completion)
• Using $@ instead of $argv (bash syntax, not fish)
• Creating in wrong directory (must be in symlinked/config/fish/functions/aliases/)
