Argument Parser for Modern C++

A simple to use, composable, command line parser for C++ 11 and beyond

Kong is a declarative command line interface framework and parser for Go. It maps flags and positional arguments directly into typed Go structures using struct tags, allowing developers to define terminal interfaces through data models rather than manual parsing logic. The project functions as a configuration mapper that populates Go structures from a combination of command-line arguments, environment variables, and JSON files. It distinguishes itself by providing a dependency injection container to pass external services into command handlers and a plugin architecture for dynamic command reg

tech-vault is a command-line technical interview bank and knowledge base designed for practicing engineering questions across various technical domains. It functions as a terminal-based application that stores structured study materials and interview questions as markdown files, which are then rendered directly within the system console. The project distinguishes itself through a delivery model that uses command-line argument parsing to filter content by topic or difficulty. It also includes a random selection algorithm to pick individual questions from the collection for spontaneous study se

This project is a set of design guidelines and a usability framework for building modern command-line interfaces based on updated Unix principles. It serves as a technical reference and manual for creating composable terminal applications that prioritize modularity and text-based communication. The guidelines cover human-centric design rules for managing interactive prompts, output formatting, and user configuration. It provides a standards-based approach to terminal application ergonomics, ensuring tools remain intuitive for humans while remaining functional for automation. The framework ad

This project is a collection of specialized toolkits designed for container interaction, Java library auditing, Linux system diagnostics, and shell task automation. It provides a suite of utilities to streamline developer workflows and system troubleshooting. The toolkit includes a Docker container helper for executing local binaries within running containers and a Java dependency analyzer to detect duplicate classes and resolve library conflicts. It also features Linux system diagnostic tools for analyzing network connection states and identifying CPU-intensive threads. The project covers b

CodeIgniter is a PHP web framework built on the Model-View-Controller pattern, designed for building full-stack web applications. It provides a lightweight toolkit with minimal configuration, organizing application logic into controllers, models, and views for clean separation of concerns. The framework includes a fluent query builder for constructing SQL statements programmatically, PSR-4 autoloading with namespace mapping, and a service-based dependency injection container for managing shared class instances. The framework distinguishes itself through its comprehensive set of built-in tools

Orpheus is a high-performance CLI framework designed to be super simple and ~30× faster than popular alternatives with zero external dependencies. Built on FlashFlags, Orpheus provides a simple interface to create modern, fast CLI apps similar to git.

FlashFlags is an ultra-fast, zero-dependency, lock-free command-line flag parsing library for Go. Originally built for Argus, it provides great performance while maintaining simplicity and ease of use.

Dotbot is a dotfile installation manager and environment setup automator designed to deploy configuration files from a repository to a local system. It functions as a symlink deployment utility and templated configuration engine, using a combination of symbolic links and custom directives to synchronize settings across machines. The project enables the automation of dotfile deployment through a shell-based configuration bootstrapper. It supports the synchronization of application profiles and the rendering of dynamic configuration files from templates before they are deployed to the filesyste

AI Chatbots in terminal for free

Simple shell script to use OpenAI's ChatGPT and DALL-E from the terminal. No Python or JS required. Formerly https://gptshell.cc

memsh - virtual in-memory shell

A readline and libedit replacement that supports UTF-8, syntax highlighting, hints and Windows and is BSD licensed.

Declarative framework for interactive CLI applications

Strumt is a library to create prompt chain

Linenoise is a lightweight C library for terminal line editing, command history management, and asynchronous input processing. It functions as a self-contained alternative for capturing user input from the command line without requiring external dependencies. The utility provides a non-blocking input processor that handles keyboard data via a feed mechanism, allowing applications to process user typing and external events simultaneously. It supports the implementation of custom shells and REPLs through features such as callback-based autocompletion, input hinting, and a circular history buffe

Fx is a command-line processing suite designed for the transformation, conversion, exploration, and visualization of structured data. It functions as a terminal-based utility that handles both automated shell pipelines and interactive navigation of complex, nested data hierarchies. The tool distinguishes itself by integrating a JavaScript-based engine that executes user-provided logic to filter, map, or modify data fields within a sandboxed runtime. It maintains a responsive interface by decoupling data processing from the display loop, allowing users to explore large datasets through an inte
