Flouncy is a library that helps developers to write fluent APIs in PHP. More precisely, it's a library that helps developers to implement the Interpreter pattern by using method chaining and capture of field/method names to record a set of tokens, which can then be parsed into a data structure or useful object.
Tripoli is a Python implementation of a "triple space": that is, a triple store with tuple space semantics. It supports the synchronization of concurrent processes via a shared data structure. Processes can add triples to the store, and read or take triples from the store using pattern matching. If a triple matching a pattern is not yet in the store, a query will block until a suitable triple is added by some other process. Many synchronization patterns can be expressed using these primitives. Tripoli extends the semantics of tuple spaces with two additional operations, copy_graph and copy_collect_graph. These copy or move the graph of all triples that are connected to a given subject to a new triple space, and can be used together with the other pattern matching operations to express procedural queries over triple data.
Variance provides a general-purpose, custom-wirable junction box for conversion between Java types. Values stored as Variants can be converted freely to any type (provided that a type converter exists between the original type and the target type), and users can add new type converters or override existing conversions.
