hgl

A collection of small easy-to-use header only libraries written in C.

library	Category	Description
hgl_arena_alloc.h	Allocator	Arena allocator.
hgl_stack_alloc.h	Allocator	Stack allocator (requires hgl_arena_alloc.h).
hgl_pool_alloc.h	Allocator	Pool allocator.
hgl_fs_alloc.h	Allocator	A "free stack" allocator. Similar to other free list allocators.
hgl_memdbg.h	Allocator/Utility	Quick and easy leak checking replacement for malloc, realloc, and free.
hgl_vector.h	Data Structure	Typed* dynamic (resizable) array.
hgl_da.h	Data Structure	Macro-only generic dynamic array implementation.
hgl_q.h	Data Structure	Macro-only generic queue (circular buffer) implementation.
hgl_hash_table.h	Data Structure	Typed* Robin Hood style hash table/map.
hgl_htable.h	Data Structure	Basically hgl_hash_table.h, but without the type stuff.
hgl_hset.h	Data Structure	Basically hgl_htable.h, but without the value.
hgl_ring_buffer.h	Data Structure	Typed* circular buffer.
hgl_rbtree.h	Data Structure	Your CS professor's ye olde red-black tree.
hgl_chan.h	Data Structure/Thread Utility	Typed* synchronized message passing utility. Similar to Go's channels.
hgl_buffered_chan.h	Data Structure/Thread Utility	Typed* and buffered synchronized message passing utility. Similar to Go's buffered channels.
hgl_string.h	Data Strucutre/Utility	Dynamic string builder, sized strings, and easy-to-use string operations.
hgl_sockets.h	Networking/Utility	A simple to use wrapper around Linux sockets (TCP/UDP)
hgl_worker_pool.h	Multithreading/Utility	Thread/Worker pool.
hgl_barrier.h	Multithreading/Utility	Barrier synchronization primitive.
hgl_hotload.h	Utility	Quick and easy hotloading.
hgl_profile.h	Utility	Quick and dirty profiling.
hgl_process.h	Utility	Utility for spawning, running, and chaining together subprocesses. Basically execvp minus the headache.
hgl_serialize.h	Utility	Powerful binary parsing and serializing/unserializing with a simple regex-like language.
hgl_cmd.h	Utility	Simple command prompt user interface with tab completion.
hgl_flags.h	Utility	Simple utility for parsing command-line arguments.
hgl_ini.h	Utility	Simple utility for parsing (and generating) *.ini files
hgl_io.h	Utility	Simple file I/O.
hgl_fft.h	Algorithm	An implementation of the Fast Fourier Transform (FFT) using SIMD.
hgl_rle.h	Algorithm	Run-length encoding and decoding. Supports multiple data and run-length block sizes.
hgl_hamming.h	Algorithm	Hamming(16,11) encoding and decoding system.
hglm.h	Math	Vector math library with some SIMD support.
hglm_aliases.h	Math	Aliases for hglm.h without hglm_ and Hglm prefixes, to make things less wordy.
hgl_test.h	Unit Testing Framework.	Simple but powerful unit testing framework.
hgl.h	Utility/Misc.	Misc. typedefs and macros that I use from time to time.

* In this context "typed" means that the type of data that is held by the data structure can be set at compile time by defining one or two macros before including.

Building

To build all examples and to build and run all tests, run:

$ make

To build all examples, run:

$ make examples

To build a specific example, run make followed by the name of the example program:

$ make fft

To build and run all tests, run:

$ make test
