The NeL Misc library contains all the core types, functionality and utilities necessary to use the Net, 3D or PACS libraries.

It also includes a handful of handy utilities that don't belong in any of the other libraries.

• Handling Command Line Options (TODO)
• Logging: Debugging macros (assertions, debugging information, warnings,...) linked to displayers
• Log Displayer: Abstracted displayer system (may be stdout, a file, a console window, etc.)
• Custom Logging: Support for multiple simultaneous log displayers.
• Custom Log Displayer: Create your own log displayer
• Log filtering functionality
• Console Commands: This system is handy for managing a command line at run time
• Console Variables
• Basic Debugging
• Using Config Files: A configuration file system capable of detecting and reloading changes to configuration

• String Utilities: Unicode string management
• Internationalization: System for management of internationaly localised text

• Serialization
• File and Path Management: A Search path management system for locating data files
• Creating and Using Big Files
• Creating and Using XML Packs
• Class Registry: The Class registry which allows instantiation of polymorphic classes by name

• Base data types, platform independent data type definitions such as sint32, uint32, etc., and exception base classes
• System information retrieval (retrieves info on the system OS, processor, RAM)
• Application Contexts
• Library Loading
• Timing Systems: OS independent time retrieval (retrieves time from local machine's clock)

• Events and Managing Input: Generalised event management system (c/f windows) used for input (keyboard, mouse, etc)
• Threading: OS independent thread & mutex management with POSIX and Windows implementations
• A system for queuing tasks for threads to process. This system is handy for things like background loading

• Quaternion classes for quaternion maths
• Matrix classes for 3D maths
• 2D and 3D vector classes in integer, single precision and double precision float implementations
• Plane class with associated functionality - projection of vector onto plane, polygon or line segment clipping against plane, etc.
• Bounding box and bounding sphere implementations with 1001 associated utility routines

• Reference counting system with smart pointers
• Block and pool based memory managers for minimisation of memory fragmentation
• A Fifo manager that houses arbitrary non-uniform sized data blocks. The fifo size is dynamic but memory allocation and liberation is minimal.
• Complete implementation of arbitrary sized bit arrays

• Complete implementation of different formats of RGBA colour representations
• Functionality for loading and treating bitmaps of different formats

These samples illustrate the usage of the Misc library.

• command: How to create commands and execute them using ICommand class. It's a generic system to create and execute commands at run time. (It is used in all services, Snowballs client and so on.)
• configfile: How to use a NeL configuration file. (This system is used in all services, snowballs client...).
• debug: How to use basic debug features that are used everywhere in NeL.
• i18n: How to use text internationalisation.
• log: Use the log and displayer system that is a generic way to generate output (on screen, file...).
• strings: Basic program to check if NeL types are valid.
• types_check: Basic program to check if NeL types are valid.
