slackbuilds/libraries/libgraphqlparser

libgraphqlparser is a parser for GraphQL, a query language created by
Facebook for describing data requirements on complex application data
models, implemented in C++11. It can be used on its own in C++ code
(or in C code via the pure C API defined in the c subdirectory), or
you can use it as the basis for an extension module for your favorite
programming language instead of writing your own parser from scratch.
