Installation

Use pony-stable

• stable add [github CandleCandle/mmdb | local-git <local path>]
• stable fetch to fetch your dependencies
• use "mmdb" to include this package
• stable env ponyc to compile your application

Test

Build and run tests with: stable env ponyc -o bin test/ && ./bin/test

Example

use "mmdb"
use "files"
use logger = "logger"

actor Main
  new create(env: Env) =>
    try
      let path = FilePath(env.root as AmbientAuth, env.args(1)?)?
      let file = File.open(path)

      let log = logger.StringLogger(logger.Error, env.out)
      let parser: Parser val = recover val Parser(file.read(file.size()), log) end
      let reader: Reader val = recover val Reader.create(parser, log)? end
      let result: Field = reader.resolve(U128.from[U32]( 0x08080808 )) // 8.8.8.8, Google's open DNS.

      Dump(env.out, result)
    end

Compile with: stable env ponyc -o bin -b mmdb-example . Run with: ./bin/mmdb-example <path to mmdb file> The MMDB files can be found (at time of writing) from https://dev.maxmind.com/geoip/geoip2/geolite2/#Databases

Notes

This follows the spec from https://maxmind.github.io/MaxMind-DB/

At time of writing, none of the example databases contain byte arrays, booleans or "data container" type fields, therefore these data types are currently left unimplemented.
