#ulib

The Universal Libary

ulib is a collection of generic useful Objective-C classes which can be used on macOS, iOS, tvOS, watchOS, Linux and probably many other Unixes. It builds on top of Foundation under Apple operating systems and GnuStep's base under Linux. It also used to work with Cocotron in the past.

What ulib includes today is

  • Dealing with Config files. (UMConfig)
  • Provide a built in HTTP Server (UMHTTPServer)
  • Dealing with Layers of communication protocols (UMLayer) and their asynchronous tasks (UMLayerTask)
  • Dealing with Background tasks (UMBackgrounder)
  • Dealing with logging (UMLogHandler)
  • Objects with a history of what changed (UM)
  • Synchronized Array and Dictionaries, Dictionaries with sorted keys
  • Task Queues and generic Queues
  • Network Sockets (TCP, UDP, SCTP) including SSL (using openSSL)
  • Micosecond timers, Locks, Timers, Througput counters
  • Json parsing and encoding
  • RedisDB Access

#History Kannel (www.kannel.org) the open source SMS gateway has a library called gwlib. This library helps the C programmer to deal with lots of daily things such as lists, dictionaries, octet strings , socket connections, config files etc. While transiting most of my code to Objective-C 2.0 to make it much easier to deal with memory management 2.0 a lot of old stuff which gwlib provided is already existing in Foundation. ulib completed Foundation with the functionality which where not in Foundation but in gwlib. Over the years many other useful functionality got added which can be used by many applications I wrote.
