Libfive is a tool for programmatic computer-aided design (CAD). In libfive, solid models are defined as Scheme or Python scripts, and there are no opaque function calls into the geometry kernel: everything is visible to the user. Even fundamental, primitive shapes are represented as code in the user-level language.

This repository contains the official KiCad documentation.

Iaito is the official graphical interface for radare2, a libre reverse engineering framework. Iaito focuses on simplicity, parity with commands, features, and keybindings.

GNU PCB is an interactive tool for editing printed circuit board layouts. It features a rats-nest implementation, schematic/netlist import, and design rule checking. It also includes an autorouter and a trace optimizer; and it can produce photorealistic and design review images.

WireViz is a tool for easily documenting cables, wiring harnesses and connector pinouts. It takes plain text, YAML-formatted files as input and produces beautiful graphical output thanks to GraphViz. It handles automatic BOM creation and has a lot of extra features.

GNUcap is a circuit analysis package. It offers a general purpose circuit simulator and can perform DC and transient analyses, fourier analysis and AC analysis. The engine is designed to do true mixed-mode simulation.

Kicad is a program for the formation of printed circuit boards and electrical circuits. The software has a number of programs that perform specific functions, for example, pcbnew (Editing PCB), eeschema (editing electrical diagrams), gerbview (viewing Gerber files) and others.

A restartable sequence is a critical region delimited by a program where if its execution is preempted or interrupted, the kernel will divert the program control flow to a defined abort handler. They are a good alternative to atomic operations for critical fast paths and are usually used in the context of per-cpu data. The library offers ABI headers to interface with the kernel and various utilities such as per-cpu counters.

pcb2gcode is a command-line program for isolation routing and drilling of PCBs. It takes Gerber files as input and outputs G-code files for the milling of PCBs. It also includes an autoleveller for the automatic dynamic calibration of the milling depth.

Zydis is a decoder and disassembler library with the following features:

• Support for all x86 and AMD64 instructions and extensions

• Optimization for high performance

• No dynamic memory allocation

• Thread-safe by design

• Smaller file-size overhead compared to other common disassembler libraries

libmodbus is a library to send/receive data with a device which respects the Modbus protocol. This library can use a serial port or an Ethernet connection.

This is a minimalist terminal program like minicom or cu. The only thing it does is creating a bidirectional connection between stdin/stdout and a terminal device (e.g. serial line). It can also set serial line baudrate, manipulate DTR/RTS modem lines, send break and throttle transmission speed.

scad-mode provides an Emacs major mode for editing OpenSCAD code. Features:

• Syntax highlighting

• Basic completion function (press M-TAB)

• Preview rendered model in separate window (press C-c C-c)

• Open buffer in OpenSCAD (press C-c C-o)

• Export buffer with OpenSCAD (press C-c C-e)

• Flymake support (enable flymake-mode in scad-mode buffers)

• Org Babel support (scad source blocks)

Enlightenment Foundation Libraries is a set of libraries developed for Enlightenment. Libraries covers data serialization, wide support for graphics rendering, UI layout and themes, interaction with OS, access to removable devices or support for multimedia.

PYTHON-EFL are the python bindings for the whole Enlightenment Foundation Libraries stack (eo, evas, ecore, edje, emotion, ethumb and elementary).

Terminology is fast and feature rich terminal emulator. It is solely based on Enlightenment Foundation Libraries. It supports multiple tabs, UTF-8, URL and local path detection, themes, popup based content viewer for non-text contents and more.

This is a process monitor and system monitor using the Enlightenment Foundation Libraries (EFL).

Rage is a video and audio player written with Enlightenment Foundation Libraries with some extra bells and whistles.

Ephoto is an image viewer and editor written using the Enlightenment Foundation Libraries (EFL). It focuses on simplicity and ease of use, while taking advantage of the speed and small footprint the EFL provide.

Ephoto’s features include:

1. Browsing the file system and displaying images in an easy-to-use grid view.

2. Browsing images in a single image view format.

3. Viewing images in a slideshow.

4. Editing your image with features such as cropping, auto enhance, blurring, sharpening, brightness/contrast/gamma adjustments, hue/saturation/value adjustments, and color level adjustment.

5. Applying artistic filters to your image such as black and white and old photo.

6. Drag And Drop along with file operations to easily maintain your photo directories.

Enlightenment is resource friendly desktop environment with integrated file manager, wide range of configuration options, plugin system allowing to unload unused functionality, with support for touchscreen and suitable for embedded systems.

entr reads a list of file names from standard input and executes a given command (including arguments) whenever any of them change. It aims to facilitate rapid feedback and automated testing.

For example, you can use entr to automatically invoke make each time you modify a source code file. It supports interactive utilities and doesn't waste resources by polling for changes.
