# Hook: Worktree Ghostty Layout
#
# Creates git worktrees in a sibling directory and opens a Ghostty terminal
# in a 2x2 layout: Claude Code (TL), lazygit (TR), terminal (BL), yazi (BR).
# Prompts for a custom branch name via macOS dialog; leave empty for auto-generated.
#
# Events:
#   - WorktreeCreate: Creates worktree + opens Ghostty 2x2 layout
#   - WorktreeRemove: Removes worktree, branch, and empty directories
#
# Requirements:
#   - jq (JSON parsing)
#   - Ghostty terminal (macOS)
#   - lazygit (git TUI)
#   - yazi (file manager TUI)
#
# Location: ~/.claude/hooks/worktree-ghostty-layout.sh
#
# Installation (add to ~/.claude/settings.json):
#   "hooks": {
#     "WorktreeCreate": [{ "hooks": [{ "type": "command", "command": "/Users/d0zingcat/.claude/hooks/worktree-ghostty-layout.sh" }] }],
#     "WorktreeRemove": [{ "hooks": [{ "type": "command", "command": "/Users/d0zingcat/.claude/hooks/worktree-ghostty-layout.sh" }] }]
#   }
#   Note: use absolute paths only — no ~ expansion in settings.json hooks.
#
# Usage:
#   1. Open Claude Code in any git repository directory
#   2. Ask Claude to create a worktree, e.g.: "work in a worktree" or "start a worktree"
#   3. Claude calls EnterWorktree → WorktreeCreate hook fires automatically
#   4. The hook creates the worktree and opens a Ghostty 2x2 split layout
#   To remove: ask Claude to "exit the worktree" → WorktreeRemove hook fires
#
# Ghostty keybindings required:
#   super+d            = new_split:right
#   super+shift+d      = new_split:down
#   super+shift+h      = goto_split:left
