Комменты

[ermouth]

Оставлю для памяти – это только комменты к драфту запускателя яваскрипт-приложений – подгружает их, окна там переключает, состояния сохраняет. Запускатель работает по урлу в браузере, причём это всё синхронный реентерантный код, несколько сот строк.

//parse url
//combine 3+params if any into array
