BlackBox Component Builder is an open-source IDE and a framework (collection of modules) written in the programming language Component Pascal which is a descendant of languages Oberon ← Modula-2 ← Pascal developed by Niklaus Wirth. BlackBox provides facilities for document creation, program compilation, module execution, and interface design. Component Pascal is module based. Each module is a unit of compilation and a unit of execution. There is no explicit linker. Modules are brought into memory when specified. There is no need for "header" files. Symbol files are automatically generated by the compiler for those elements of a module that are specifically marked to be exported.
The component classes (e.g. for text or form components) follow the principle of black box inheritance (interface inheritance instead of implementation inheritance), hence the name "BlackBox".
The compiler is very fast. The language is strongly typed. Data structures are automatically garbage collected when no longer referenced. The framework comes with a complete set of documents explaining the meaning and use of each module.
Note: to view BlackBox documents in the terminal and for git diff, recommended to install odcey.
Also contains the experimental version BlackBox 2 available by command bbcb.2

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap can be installed from the command line on openSUSE Leap 15.x and Tumbleweed.
You need first add the snappy repository from the terminal. Leap 15.5 users, for example, can do this with the following command:
sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Leap_15.5 snappy
Swap out openSUSE_Leap_15.5 for openSUSE_Leap_15.4 or openSUSE_Tumbleweed if you’re using a different version of openSUSE.
With the repository added, import its GPG key:
sudo zypper --gpg-auto-import-keys refresh
Finally, upgrade the package cache to include the new snappy repository:
sudo zypper dup --from snappy
Snap can now be installed with the following:
sudo zypper install snapd
You then need to either reboot, logout/login or source /etc/profile to have /snap/bin added to PATH.
Additionally, enable and start both the snapd and the snapd.apparmor services with the following commands:
sudo systemctl enable --now snapd
sudo systemctl enable --now snapd.apparmor
To install BlackBox Component Pascal Builder, simply use the following command:
sudo snap install bbcb --edge
Browse and find snaps from the convenience of your desktop using the snap store snap.
