    Your basic graph

    Your basic graph

    Graph algorithms and data structures

    A graph implementation based entirely on functions. This text is about the implementation of a Go tool based entirely on functions – the API contains only immutable data types, and the code is built on top of a struct with five function fields. It’s a tool for building virtual graphs. In a virtual graph no vertices or edges are stored in memory, they are instead computed as needed. The tool is part of a larger library of generic graph algorithms.

    TypeScript Collections

    TypeScript Collections

    A generically typed set of collections for use with TypeScript

    TypeScript Collections is a fully tested library of generic data structures for TypeScript and JavaScript applications. It provides linked lists, dictionaries, trees, stacks, queues, sets, bags, heaps, and priority queues. Generic typing lets editors provide autocomplete while the compiler checks the types stored in each collection. The package supports ES module imports, TypeScript require syntax, CommonJS, browser scripts, and Universal Module Definition builds.

    Cello

    Cello

    Higher level programming in C

    Cello is a library that brings higher level programming to C. By acting as a modern, powerful runtime system Cello makes many things easy that were previously impractical or awkward in C such as generic data structures, polymorphic functions, interfaces / type classes, constructors / destructors, optional garbage collection, exceptions, and reflection. And because Cello works seamlessly alongside standard C you get all the other benefits such as great performance, powerful tooling, and extensive libraries. I made Cello as a fun experiment to see what C looks like hacked to its limits. ...

    libcutils

    Some Useful C-Utilities

    Libcutils provides a self-contained set of fundamental routines which are essential to basically any Unix utility or daemon application written in C. The library provides fundamental data structures such as lists, hash-maps, strings and parsing functions for JSON or the typical dot-file based configuration data. The following list summarizes the currently supported functionality: * length delimited instead of NULL terminated strings * memory management based on reference counting * several list processing functions like iterators and map-reduce * support of [Ideal Hash Tries](http://infoscience.epfl.ch/record/64398/files/idealhashtrees.pdf) for highly efficient hash map data structures * parsers for [JSON](http://json.org) data and the text configuration files found in Unix system * doubly linked circular lists for reliable event queues * support for test and debugging of memory management problems such as memory leaks

    SPARGEL

    An opensource Java graph library. Abandoned, ignore.

    ...Because these maps are an individual implementation depending on the graph datastructure used, they are more memory efficient than using a Java HashMap. Currently spargel is in its early stages, but will soon support more tasks. As now, implemented are: * Adjecency graph data structures * Algorithms: SSSP, APSP, Traversal, Min-Cut, Max-Flow, Many types of finding Components * Creating sub graphs, vertice and edge maps that use a function to implement their mapping. Spargel is released under GPLv3

    PyGCF

    Process GURPS Character Assistant GCF files to Python structures

    The GURPS Character Assistant program stores its core data as GCF files. These files contain a descriptions of entities and relationships, commands for manipulating them and rules on how to satisfy constraints. Unfortunately, said program is only available for Windows, doesn't support any kind of automation for generation of NPCs, doesn't function under WINE, and is very, very slow. This module is intended to provide a basis for rectifying those problems.
