Добро пожаловать в среду моделирования и технических расчетов Engee
Прежде чем начать...
Перед вами интерактивный скрипт Engee. Он состоит из секций кода и текста. Каждая секция, содержащая код, может быть запущена независимо от других:
Кроме того, скрипт можно выполнить целиком:
Скорее всего, сейчас перед вами открыто окно с редактором скриптов и файловым менеджером.
Холст для редактирования моделей находится на фоне, позади всех окон. Можете их закрыть или переключиться в другой "Сценарий".

Получение утилиты обновления каталога демонстраций
Ячейка кода, расположенная ниже, загрузит последнюю версию утилиты обновления каталога демонстраций из репозитория Engee.
In [ ]:
if isdir("/user/start/content_updater")
rm("/user/start/content_updater";force = true, recursive = true)
end
run(`git clone https://git.engee.com/learn-engee/content-catalog.git /user/start/content_updater`)
Cloning into '/user/start/content_updater'...
Out[0]:
Process(`git clone https://git.engee.com/learn-engee/content-catalog.git /user/start/content_updater`, ProcessExited(0))
Использование утилиты refresh_demo_catalog
В папке start -> content_updater откройте скрипт refresh_demo_catalog.ngscript. Скрипт разбит на секции, каждая из которых содержит описание демонстрации или курса. Для обновления или получения каждого курса или демонстраций по отдельности запустите соответствующую ячейку кода. Для того чтобы обновить весь контент, запустите ячейку ниже:
In [ ]:
engee.script.run("/user/start/content_updater/refresh_demo_catalog.ngscript")
Load script `/user/start/content_updater/refresh_demo_catalog.ngscript`
