+### 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
