gqlite 1.0.0

GQLite is a C++-language library, with a C interface, that implements a small, fast, self-contained, high-reliability, full-featured, Graph Query database engine. The data is stored in a SQLite database, which the fasted and most used SQL database. This enable to achieve high performance and for application to combine Graph queries with traditional SQL queries. GQLite source code is license under the [MIT License](LICENSE) and is free to everyone to use for any purpose. The official repositories contains bindings/APIs for C, C++, Python, Ruby and Crystal. The library is still in its early stage, but it is now fully functional. Development effort has now slowed down and new features are added on a by-need basis. It supports a subset of [OpenCypher](https://opencypher.org/), and the intent is to also support ISO GQL in the future when it become available. Example of use -------------- ```ruby require 'gqlite' begin # Create a database on the file "test.db" connection = GQLite::Connection.new sqlite_filename: "test.db" # Execute a simple query to create a node and return all the nodes value = connection.execute_oc_query("CREATE () MATCH (n) RETURN n") # Print the result if value.nil? puts "Empty results" else puts "Results are #{value.to_s}" end rescue GQLite::Error => ex # Report any error puts "An error has occured: #{ex.message}" end ``` The documentation for the openCypher query language can found in [openCypher](https://gitlab.com/gqlite/GQLite/-/blob/docs/opencypher.md) and for the [API](https://gitlab.com/gqlite/GQLite/-/blob/docs/api.md).
