This package opens a notebook, strips its output, and writes the outputless version to the original file.

This package provides a pytest plugin for testing Jupyter libraries and extensions.

NbClassic provides a backwards compatible Jupyter Notebook interface that you can install side-by-side with the latest versions: That way, you can fearlessly upgrade without worrying about your classic extensions and customizations breaking. Because NbClassic provides the classic interface on top of the new Jupyter Server backend, it can coexist with other frontends like JupyterLab and Notebook 7 in the same installation. NbClassic preserves the custom classic notebook experience under a new set of URL endpoints, under the namespace /nbclassic/.

This package provides a Jupyter Server extension for serving Mathjax, the JavaScript display engine for mathematics.

A bash shell kernel for Jupyter.

Papermill is a tool for parameterizing, executing, and analyzing Jupyter Notebooks.

This package provides the backend—i.e. core services, APIs, and REST endpoints—to Jupyter web applications.

Jupytext is a plugin for Jupyter that can save Jupyter notebooks as either Markdown files or scripts in many languages. Common use cases for Jupytext are:

• version control on Jupyter Notebooks

• editing, merging or refactoring notebooks in your favorite text editor

• applying Q&A checks on notebooks.

xeus is a library meant to facilitate the implementation of kernels for Jupyter. It takes the burden of implementing the Jupyter Kernel protocol so developers can focus on implementing the interpreter part of the kernel.

Several Jupyter kernels are built upon xeus, such as xeus-cling, a kernel for the C++ programming language, and xeus-python, an alternative Python kernel for Jupyter.

This package provides a Sphinx extension for deploying JupyterLite.

The package provides a PARI/GP kernel for Jupyter.

GNU Kawa is an implementation of the Scheme programming language that is built on top of the Java platform. It is thus conveniently integrated with Java and benefits from this by having a compiler, optional static typing, and so on. Kawa also serves as a framework for implementing other programming languages on the Java platform. Included in Kawa is qexo, a partial implementation of XQuery in Java.

Analitza is a library to work with mathematical objects. It adds mathematical features to your program, such as symbolic computations and some numerical methods; for instance the library can parse mathematical expressions and let you evaluate and draw them.

KTouch is an aid for learning how to type with speed and accuracy. It provides a sample text to type and indicates which fingers should be used for each key. A collection of lessons are included for a wide range of different languages and keyboard layouts, and typing statistics are used to dynamically adjust the level of difficulty.

This package provides a QtQuick plugin to render beautiful and interactive charts.

LabPlot is a tool for interactive graphing and analysis of scientific data. It provides an easy way to create, manage and edit plots and to perform data analysis.

KAlgebra is a calculator that lets you plot different types of 2D and 3D functions and to calculate easy (and not so easy) calculations, such as addition, trigonometric functions or derivatives.

Gcompris offers a large collection of educational games for small children, designed to be a unified interface to integrate more educational games. Language-oriented games contain vocabulary, sounds, and voices for many different languages. Currently available boards include:

1. learning how to use a mouse and keyboard

2. learning simple arithmetic

3. learning how to read an analog clock

4. recognize letters after hearing their names

5. reading practice

6. small games (memory games, jigsaw puzzles, ...)

Marble is similar to a desktop globe. At closer scale it becomes a world atlas, while OpenStreetMap takes the user to street level. It supports searching for places of interest, viewing Wikipedia articles, creating routes by drag and drop and more.

The KDE GUI addons provide utilities for graphical user interfaces in the areas of colors, fonts, text, images, keyboard input.

KConfig provides an advanced configuration system. It is made of two parts: KConfigCore and KConfigGui.

KConfigCore provides access to the configuration files themselves. It features:

1. Code generation: describe your configuration in an XML file, and use `kconfig_compiler to generate classes that read and write configuration entries.

2. Cascading configuration files (global settings overridden by local settings).

3. Optional shell expansion support (see docs/options.md).

4. The ability to lock down configuration options (see docs/options.md).

KConfigGui provides a way to hook widgets to the configuration so that they are automatically initialized from the configuration and automatically propagate their changes to their respective configuration files.

KDNSSD is a library for handling the DNS-based Service Discovery Protocol (DNS-SD), the layer of Zeroconf that allows network services, such as printers, to be discovered without any user intervention or centralized infrastructure.

KWindowSystem provides information about and allows interaction with the windowing system. It provides a high level API, which is windowing system independent and has platform specific implementations. This API is inspired by X11 and thus not all functionality is available on all windowing systems.

In addition to the high level API, this framework also provides several lower level classes for interaction with the X Windowing System.

This package provides library that is used when writing accessibility clients such as screen readers.
