ftg_base89.h

An implementation of Printable Base89 Lut Encoding in C.

This header file lets you encode lookup tables into UTF-8 strings, which you can use for your own purposes including theming or semantic markup. It includes a reasonably high performance set of functions to process strings containing these encodings, as well as pack and unpack Base89 LUT Encoded sequences.

ftg_bitbuffer.h

Tightly pack values by bits into a stream of bytes for reading / writing.

For example, a 1-bit bool and a 32-bit integer are packed into 33 bits.

Bitbuffers are intended for small amounts of data, such as a few hundred network packets where size is important enough to remove padding bits, and the cpu overhead of packing/unpacking intermixed types is not a huge cost.

• Compiles C99 warnings-free on clang and visual c++

• Pack integers with arbitrary numbers of bits

• Supports quantized floating point packing

• Possible to avoid all heap allocations and copies on read
