Mathomatic is a portable, general-purpose computer algebra system (CAS) that can solve, differentiate, simplify, combine, and compare algebraic equations, perform standard, complex number, modular, and polynomial arithmetic, etc. It does some calculus and is very easy to compile/install, learn, and use. The symbolic math application with a simple command-line interface is designed to be a colorful algebra calculator that is reliable, responsive, and convenient to use. The symbolic math library is lightweight and easy to include in other software, due to being written entirely in C with no additional dependencies.
JCmdLineProgress is a Java library to assist with progress reporting on the command line. Using simple hooks, a program can send progress messages and status information to the command line. Also, text based "spinners" can be used to provide visual confirmation that a long running but quiet program is still running. A working example is provided.
CLI is a command line interface compiler for C++. It allows you to specify the options that your program supports, their types, and default values. This specification can then be translated to C++ classes that implement parsing of the command line arguments and provide a convenient and type-safe interface for accessing the extracted data.
The Teleport command is a replacement for the traditional cd command. More accurately, it's a wrapper around the cd command, with various improvements. It keeps a history of the directories you have visited. You can easily jump to any directory in your history. You can display your history. You can easily create aliases for directories to make it even easier to jump to them.
FontMapper is a font texture generator for game developers. It allows you to turn a font you have installed to a PNG texture of tightly packed glyphs, accompanied by a text file describing the glyphs' properties and texture coordinates. You can read these in a game to render fonts. FontMapper supports Unicode (although only the Basic Multilingual Plane, i.e. the 16-bit codepoints), and each glyph can have its own size, i.e. fonts are not necessarily monospaced. Currently, FontMapper is command-line only, although there might be a GUI frontend in the future.
Clicco is a tool for constructing command line commands based on saved configurations. It is ideal if you have difficulty remembering the exact commands, arguments, or argument values for various situations, as you can save commands with various argument choices for future use along with a description.
PHP CLI Framework is a simple class which you can extend to quickly create a commandline (CLI) application using PHP. Only a single file is needed, and everything extends that file. It supports interactive input and an object oriented way of writing which keeps things nice and clean. Features include arguments, flags, options, colors, interactive input, object oriented PHP5, a micro framework, and minimal coding required. There's only a single class to extend.
