### Luagraphqlparser
Lua-binding of [libgraphqlparser](https://github.com/graphql/libgraphqlparser)
compatible with [graphql-lua](https://github.com/bjornbytes/graphql-lua).
Differences from graphql-lua parser:
* Improved error messages
* Null support
Usage:
```lua
parse = require('luagraphqlparser').parse
parse([[
query HeroComparison($first: Int = 3) {
leftComparison: hero(episode: EMPIRE) {
...comparisonFields
}
rightComparison: hero(episode: JEDI) {
...comparisonFields
}
}
fragment comparisonFields on Character {
name
friendsConnection(first: $first) {
totalCount
edges {
node {
name
}
}
}
}
]])
