Automatically open the last session

[jakob1379]

I made this wrapper, which in essence just saves the latest session id in a .droid file. If such a file exists this file will be used unless the -n|--new flag is used. That way I do not manually have to search for the last session in the project.

I would probably prefer this to be in the root of a git project, otherwise, just where droid is launched.

I might have overdone it a bit in terms of splitting it up, but the idea I still like. So what I propose is a similar functionality builtin to droid cli, e.g. just let it be a config setting the behaviour

#!/usr/bin/env bash

# Constants
readonly SESSION_FILE=".droid"
readonly SESSION_PATTERN='droid --resume [a-f0-9-]*'

# Cleanup temporary files on exit
cleanup() {
  local exit_code=$?
  [[ -n "${stderr_file:-}" && -f "$stderr_file" ]] && rm -f "$stderr_file"
  return "$exit_code"
}
trap cleanup EXIT

# Extract session ID from stderr output
extract_session_id() {
  local stderr_file="$1"

  if ! grep -q "$SESSION_PATTERN" "$stderr_file"; then
    return 1
  fi

  grep -o "$SESSION_PATTERN" "$stderr_file" | \
    sed 's/droid --resume //'
}

# Save session ID to file
save_session_id() {
  local session_id="$1"
  echo "$session_id" > "$SESSION_FILE"
}

# Load session ID from file, clean up if empty
load_session_id() {
  [[ ! -f "$SESSION_FILE" ]] && return 1

  local session_id
  session_id=$(cat "$SESSION_FILE" | tr -d '[:space:]')

  if [[ -z "$session_id" ]]; then
    rm -f "$SESSION_FILE"
    return 1
  fi

  echo "$session_id"
}

# Main execution
main() {
  local stderr_file
  local session_id
  local force_new_session=false
  local droid_args=()

  # Simple argument parsing
  for arg in "$@"; do
    case "$arg" in
      -n|--new)
        force_new_session=true
        ;;
      *)
        droid_args+=("$arg")
        ;;
    esac
  done

  stderr_file=$(mktemp)

  # Attempt to resume existing session
  if [[ "$force_new_session" == false ]] && session_id=$(load_session_id); then
    echo "Resuming droid session: $session_id"
    droid --resume "$session_id" "${droid_args[@]}" 2>"$stderr_file"
  else
    droid "${droid_args[@]}" 2>"$stderr_file"
  fi

  # Extract and persist any new session ID
  if new_session_id=$(extract_session_id "$stderr_file"); then
    save_session_id "$new_session_id"
    echo "Session ID saved: $new_session_id" >&2
  fi
}

main "$@"

I tried to overdo it to follow best practices, but I guess it could be done much more compact 😅

I solved this by creating a mise.toml with a enter hook and a small python script that checks for existing sessions and offers them with timedate via fzf. it also checks for an existing .droid yes. thanks for that.
