Json-buffet

json-buffet is a little tool to help parse streaming json. Directly view and pick only the values you wish to consume.

Installation

You need a recent C++ toolchain and CMake to use json-buffet

$ mkdir build && cd build
$ cmake ..
$ cmake --build .
$ cat ../test.json | ./json-buffet

Usage

Just pipe any json file as input to json-buffet and provide it with the path you are interested in.

$ ./json-buffet
Usage: ./json-buffet /path/to/item/of/interest < /path/to/json
Note: You can use empty path components to represent an element of an array.
eg. item//key/ on  { "item": [ {"key": "value1"}, {"key": "value2"} ] } fetches value1 and value2
