#
# Claude Code SessionStart/SessionEnd hook for cmux session resume.
#
# Hook script for automatically resuming Claude Code during cmux session restoration.
# Register in settings.json for both SessionStart and SessionEnd.
#
# ---- Operation Overview ----
#
# SessionStart:
#   Gets workspace name / tab index / tab name from cmux CLI,
#   and saves them to a cache file for each session ID.
#   We cache this here because cmux CLI doesn't work during SessionEnd.
#   If session_source is "resume", delete the corresponding marker
#
# SessionEnd:
#   Creates a marker file if reason is "other".
#   "other" triggers on cmux ⌘+Q or ⌘+W.
#   Deletes cache if reason is "prompt_input_exit".
#
# ---- File Structure ----
#
# Cache: $cwd/.claude/cmux-tab-info/$session_id
#   Created at SessionStart. Stores workspace_name, tab_index, tab_name in key=value format.
#
# Marker: $cwd/.claude/cmux-session-resume/$session_id
#   Created at SessionEnd (reason: "other"). Copy of cache contents.
#   The zsh plugin detects this to suggest resume.
#
# ---- Why use workspace name for matching ----
#
# workspace ref (e.g. "workspace:1") can change ordering due to workspace additions/removals
# or Claude Code notifications, making it unstable after restart.
# workspace name (e.g. "workspace") doesn't change unless explicitly renamed by user,
# making it a better identifier for matching.
#
# Known limitation: If a workspace is renamed during a session,
# the cache will still have the old name and matching will fail.
#
# ---- Note about stdout ----
#
# Due to Claude Code hooks' design, output to stdout is injected into Claude's context.
# To avoid context consumption, this script avoids stdout output completely.
# File operations use redirection (> file) to avoid stdout.

# Common prefix for python3 JSON parsing.
# Using python3 since macOS doesn't have jq installed by default.

#
# cmux-claude-resume: Automatically resume Claude Code when restoring cmux sessions
#
# ---- Overview ----
#
# cmux restores layouts and working directories on session restoration,
# but not processes (Claude Code) within panes.
# This plugin detects marker files at zsh startup after cmux restoration
# and suggests resuming the corresponding Claude Code session.
#
# ---- Marker Files ----
#
# Markers are created by Claude Code SessionEnd hook (reason: "other").
# Location: $cwd/.claude/cmux-session-resume/$session_id
# Contents: key=value format (workspace_name, tab_index, tab_name, session_name)
#
# ---- Matching Conditions ----
#
# Resume is suggested when all 3 conditions match:
#   1. Directory: Marker exists in $PWD/.claude/cmux-session-resume/
#   2. workspace name: Marker's workspace_name matches current
#   3. tab index: Marker's tab_index matches current
#
# Why use workspace name instead of workspace ref:
#   workspace ref numbers can shift when adding/removing workspaces.
#   workspace name remains stable unless explicitly renamed.
#
# ---- Multiple Sessions in Same Directory ----
#
# Using mv to atomically acquire markers prevents race conditions
# when multiple zsh processes start simultaneously.
# Since macOS doesn't include flock by default, mv is used instead.
# mv is guaranteed atomic for same filesystem by POSIX.
# First to mv gets the marker, failures try next marker.
#
# ---- Marker Deletion ----
#
# Markers are deleted at these times:
#   - After successful resume: By SessionStart hook (source: "resume")
#   - When cancelled: By this plugin (cache also deleted)
#   - When expired: By this plugin (markers older than 1h)
#
# ---- Known Limitations ----
#
# If workspace is renamed during session,
# cache retains old name and matching will fail.
