Async JSON

A library for parsing json in parts avoiding the need to keep the complete document in memory. The parsing works through a statemachine with a state stack for nested arrays and objects.

ATTENTION

In the current state valid json documents are mis-parsed because " escape sequences are not yet supported.

TODO:

• handle grammar relevant escape sequences in input stream
• provide utilities to optionally convert \u unicode escape symbols and similar
• optimize binary size and performance by improving hsm
• find a better way to parse floats/doubles.
• printing

Dependencies

• optional C++ std features like string_view

• hsm: https://github.com/APokorny/hsm (so transitively kvasir mpl and https://github.com/APokorny/tiny_tuple)

• Example setup:

project(async_json_env LANGUAGES CXX)
cmake_minimum_required(VERSION 3.10)
cmake_policy(SET CMP0057 NEW)
cmake_policy(SET CMP0048 NEW)
set(as_subproject
    kvasir_mpl hsm tiny_tuple)

macro(find_package)
    if(NOT ${ARGV0} IN_LIST as_subproject)
        _find_package(${ARGV})
    endif()
endmacro()

add_subdirectory(mpl)
add_subdirectory(tiny-tuple)
add_subdirectory(hsm)
add_subdirectory(async_json)
