SLDM v1.2.5 — fast image lists and keyboard navigation

SLDM 1.2.5 — faster image lists and keyboard navigation

Both scripts have the same features:

• English: sldm_en.1.2.5.sh
• Russian: sldm_ru.1.2.5.sh

Changes

• Moved the heavy docker system df image-size query to the background. The image list appears without waiting for that query; exact size is cached for 30 seconds and updates once the query finishes.
• Added ↑/↓ selection and Enter navigation to the main menu and image list.
• Repaint only the old and new highlighted rows in a suitably sized terminal, eliminating full-screen redraws during selection.
• Added ←/→ pagination for image and container lists, preserving n/p shortcuts.
• Adapt image page size to terminal height and handle idle terminal resizes.
• Added selected-image actions: layer history, Pull, Push and Delete.
• Delete requests removal of the highlighted image; y/Y confirms and any other key cancels. The target is pinned to the displayed image ID, and this action does not use -f.
• Esc returns to the parent menu from the lists, cleanup menu and selected-image actions.
• Private temporary cache directories, background image-size worker cleanup, and bounded escape-sequence parsing.
• Updated English/Russian README, installation commands, hotkeys and cleanup warnings.

Validation

Bash syntax checks and 26 regression tests passed for each language (52 tests total). Tests use a fake Docker CLI; no real Docker resources were removed.

Safety

Existing batch/prune actions are separate and remain potentially destructive. The new y confirmation applies only to single-image deletion, not every cleanup action. Check your target before deleting.

Русский — изменения в 1.2.5

• Ускорено открытие списка образов: тяжёлый docker system df работает в фоне, точный размер образов кэшируется на 30 секунд.
• Стрелки ↑/↓ выбирают раздел в главном меню или образ в списке; Enter открывает раздел или действия выделенного образа.
• При перемещении выделения в терминале подходящего размера обновляются только две строки, без очистки экрана.
• Добавлена пагинация ←/→ для образов и контейнеров; n/p сохранены.
• Размер страницы образов подстраивается под высоту терминала, изменение размера окна обрабатывается автоматически.
• Меню выбранного образа: история слоёв, Pull, Push и удаление.
• Delete вызывает подтверждение удаления выбранного образа: y/Y — удалить, другая клавиша — отменить. Удаление по ID отображённого образа, без -f.
• Esc возвращает на уровень выше из списков, меню очистки и действий образа.
• Приватный временный кэш, завершение фонового подсчёта размера образов и безопасный разбор клавиш.
• Обновлён README на двух языках: установка, горячие клавиши и предупреждения об очистке.

Проверены обе версии: Bash-синтаксис и по 26 тестов (52 всего), без удаления реальных ресурсов Docker.
Массовое удаление и prune остаются отдельными потенциально разрушительными действиями; подтверждение y относится только к удалению одного образа.

SLDM v1.2.4

bug fix
new function Add show_image_history function to display layer history

SLDM v1.2.3 Final Release — best bash-docker manager 2025 year

🚀 Optimization & Hardware (System & Hardware)

• Moved Cache to RAM (/dev/shm):

  • Cache and lock files (.cache, .lock) are now created in /dev/shm (Shared Memory).
  • Why: This eliminates constant writing to the SSD/SD card during every statistic update (once per second), which is critical for the longevity of flash storage on Raspberry Pi and other single-board computers.
  • Speed: Read/write operations in RAM are instantaneous.

• Universal Compatibility:

  • Added a check for the existence of /dev/shm.
  • If the script is running on a system without Shared Memory (e.g., macOS or specific container environments), it automatically falls back to using /tmp.

🐛 Bug Fixes

• Disk Statistics:
  • Improved parsing of the docker system df command.
  • Added handling for empty values: if Docker has not yet calculated the image sizes, the script now correctly displays 0B instead of an empty string or an error.

🌍 Localization

• Synchronization:
  • All technical improvements have been ported to the English version of the script.

SLDM v1.2.3 Final Release — лучший bash-докер-менеджер 2025 года

🚀 Оптимизация и Железо (System & Hardware)

1. Перенос кэша в RAM (/dev/shm):

   • Файлы кэша и блокировок (.cache, .lock) теперь создаются в /dev/shm (Shared Memory).
   • Зачем: Это исключает постоянную запись на SSD/SD-карту при каждом обновлении статистики (раз в секунду), что критически важно для долговечности флеш-памяти на Raspberry Pi и других микрокомпьютерах.
   • Скорость: Чтение/запись в оперативную память происходит мгновенно.

2. Универсальная совместимость:

   • Добавлена проверка наличия /dev/shm.
   • Если скрипт запущен на системе без Shared Memory (например, macOS или специфичные контейнеры), он автоматически откатывается на использование /tmp.

🐛 Исправления ошибок (Bug Fixes)

3. Статистика диска:
   • Улучшен парсинг команды docker system df.
   • Добавлена защита от пустых значений: если Docker еще не подсчитал размер образов, скрипт корректно выведет 0B вместо пустоты или ошибки.

🌍 Локализация

4. Синхронизация:
   • Все технические улучшения перенесены в Английскую версию скрипта.

📖 Обзор

SLDM v1.2.2 (Async Edition) — это полноценный TUI-инструмент для управления Docker. Главное отличие от обычных скриптов — асинхронное ядро. Скрипт не "виснет" при подсчете памяти контейнеров, а выполняет это в фоне, обновляя интерфейс на лету.

Идеальная замена lazydocker для слабых машин или серверов, где важна каждая мегабайт памяти.
