/**
zpl - Pushing the boundaries of simplicity.
Usage:
# define ZPL_IMPLEMENTATION exactly in ONE source file right BEFORE including the library, like:
# define ZPL_IMPLEMENTATION
# include "zpl.h"
You can also use a lightweight version of zpl by using ZPL_NANO, like:
# define ZPL_IMPLEMENTATION
# define ZPL_NANO
# include "zpl.h"
There is also a distribution that provides only the essential modules, you can enable it by defining ZPL_PICO.
Currently, the distro offers: preprocessor helpers, debug module, memory API (except vm) and collections.
Some of these modules used to depend on zpl_printf, but they use the standard library if the distro is enabled now.
# define ZPL_IMPLEMENTATION
# define ZPL_PICO
# include "zpl.h"
Options:
ZPL_EXPOSE_TYPES - exposes all zpl defined types to the global namespace. This means type such as `zpl_u32` is now available as `u32` globally.
ZPL_DEFINE_NULL_MACRO - to let zpl define what NULL stands for in case it is undefined.
ZPL_NO_MATH_H - disables the use of math.h library and replaces it with custom routines or SIMD.
ZPL_HEAP_ANALYSIS - enables heap allocator analysis tools
emscripten support
2022-09-11 17:42:06 +00:00
ZPL_PARSER_DISABLE_ANALYSIS - disables the extra parsing logic that would collect more information about node's formatting and structure.
this is useful in scenarios where a raw parsing performance is preferred over a more complex analysis.
It is not recommended to serialise data back since we lack the extra information about the original source document.
