Piglet is a tool for parsing and lexing text for the .NET framework. The purpose of Piglet is to provide an easy-to-use tool for parsing text which can be easily included in any .NET project as a single assembly. In contrast to most parser generators, Piglet provides a fluent interface which enables you to express your grammar in a syntax which is accessible for users with no prior experience of parser generators. Piglet generates efficient, type safe, and reentrant LALR(1) parsers at runtime, which saves you from having a pre-compile step to generate your parsing tables. It also includes a lexical scanner generator which can be used independently of the parser generator.
The KoreLogic Expression Language Library (libklel) is a C library that provides a simple expression language that can be embedded in other programs. It does not implement a full programming language, but rather a simpler expression language called KL-EL that is designed to provide arithmetic and logic operations in situations where embedding a full programming language would be overkill. KL-EL can access functions and variables exported from the embedding program, and is statically and strongly typed, which helps ensure that expressions are valid before they are executed. The embedding API is easy to use, and the library itself is very small.
OpenUDID provides a cross-platform method for generating globally unique per-device identifiers. UDIDs are used for analytical or CRM purposes, such as to track how much time users spend in free apps before upgrading to the paid version, or for tracking the source of a download when advertising on an ad network.
The stx::CBTreeDB is a collection of C++ classes with which read-only key-value database files can be created and read. A database efficiently maps a large number of integral fixed-length keys to opaque binary value blobs. Variable-length or duplicate keys are currently not supported. Keys are organized into a highly compact index structure, which is very similar to a B-tree and allows very fast key lookups. Both keys and values are stored in order and thus queries in a local proximity can benefit from caching effects. All applications mapping a large number of constant, integral keys to string or data blobs can benefit from this library.
Blacken is a Java library for Roguelike development. It supports arbitrarily resizing the window. It maintains a "preferred size", changing the font size as needed. By default, all applications support Alt-Enter for fullscreen mode. It strives to support Unicode well. A cell contains a sequence of codepoints. Codepoints may be outside the Basic Multilingual Plane or zero-width accents. All key input consists of valid Unicode codepoints. Special keys are handled by codepoints in "private use" planes. Modifier keys are handled through a prefix character (like Unix systems handle Alt via the Escape character).
lambdaj is a Java library that allows you to manipulate collections in a pseudo-functional and statically typed way. The main purpose of lambdaj is to partially eliminate the burden of writing (often nested and poorly readable) loops while iterating over collections. In particular, it allows you to iterate a collection in order to filter its items on a given condition, convert each item with a given rule, extract a given property from each item, sort the items on the values of one of their properties, group or index the items on the value of one or more properties, invoke a method on each item, or aggregate the items or the values of one of their properties. It allows all this without having to write a single explicit loop.
oauth-php is a PHP library for OAuth consumers and servers. It has an extensible OAuth store, including a full working implementation of a MySQL store. The library implements methods to: verify incoming requests against the library; to sign outgoing requests, with curl support for actually doing the request; to sign requests with a body; to administrate consumer keys and tokens for multiple users (server and consumer side); and to log incoming and outgoing requests handled by the library (optionally in the database).
