Shell Completion Support

Simple-CLI supports multiple shell completion systems:

Available Completion Systems

• Bash: Default completion system (already supported)
• Fish: Rich completion with descriptions
• Zsh: Advanced completion system
• Nushell: Modern shell completion

Configuration

Edit ~/.simple_cli/config.json to customize completion:

{
  "syntax": {
    "enabled_completion_shells": ["fish", "zsh", "bash", "nushell"],
    "completion_shell_order": ["fish", "zsh", "bash", "nushell"],
    "fish_completion_dirs": [
      "~/.config/fish/completions",
      "/usr/share/fish/completions"
    ],
    "zsh_completion_dirs": [
      "~/.zsh/completions",
      "/usr/share/zsh/functions/Completion"
    ],
    "nushell_completion_dirs": [
      "~/.config/nushell/completions"
    ]
  }
}

How It Works

1. Simple-CLI tries each enabled shell in the specified order
2. First shell that returns completions wins
3. Fish completions include descriptions (if available)
4. Falls back to bash completion if others fail
