Under Construction

ldc-framework Version 0.1.0-b1
April 22, 2020.

ldc-framework: The LDC Framework project.

Overview

The primary goal of the LDC Framework project is to streamline Docker container development by providing:

a container structure which lends itself to replication within each created container, including those used as a base for a new container;
a directory structure allowing for utility libraries and scripts, a standard, expandable Docker-host interface, and well defined internal structure for consistent behavior of system daemons and developed applications;
Kaptain, Dialog, Whiptail and Zenity to provide simple dialog boxes;
CKaptain pop-up dialog boxes, based on Kaptain, to provide
- form-based user interfaces for scripts and console-based applications,
- easily defined, form-based input of options for console-based applications;
framework stacks for
- single development language applications (for example: C++ Run-time, or Java Run-time Environment);
- multiple development language applications, (for example: GTK-3 with C++, or Java Run-time Environment plus GTK-3); and
- specialized multi-layered development languages for applications (for example: C++, GTK-3 and Java Runtime Environment for LibreOffice).

Framework Construction Blocks

The LDC Framework is constructed using multiple levels of construction blocks, or frames:

ldc-core: The LDC Core project is the foundational member of the LDC framework, providing the core frame required to construct new applications and frames.
ldc-library: The LDC Library project provides the scripts, special purpose maintenance libraries and applications, and the Docker-host interface structure, for a standard look and feel across all stack frames and derivative projects.
ldc-base: The LDC Base project combines the LDC Library project with the LDC Core project and additional support frames to provide a progressively complex multimedia foundation base.
ldc-stack: The LDC Stack project extends ldc-base by providing simple run-time environments for additional development language requirements.
ldc-stack-dev: The LDC Stack-dev project contains framework stacks for applications requiring support of development libraries to build new applications, libraries and frames.
ldc-stack-apps: The LDC Stack Apps project provides framework stacks designed for specific applications and are derived from frames in LDC Base, LDC Stack, LDC Stack Dev and LDC Stack Apps.
ldc-dialog: The LDC Dialog project provides Dialog, Kaptain, WhipTail and Zenity applications for displaying dialog boxes from shell scripts.
ck-library: The LDC CK-Library project provides CKaptain template and widget libraries to make it easy to develop interactive interfaces using run-time option templates and pre-defined pop-up dialogs for use in scripts and applications.
ckaptain: The LDC CKaptain project leverages the LDC Dialog project's Kaptain application and the LDC CK-Library project's library structures to allow creation of pop-up dialog boxes in form-based user interfaces for scripts and console-based applications, as well as easily defined, form-based input of complex options for console-based applications.

NOTE

ewsdocker/ldc-framework is designed to be used on a Linux system configured to support Docker user namespaces, or userns.
