Since I'm fairly new to Logstash and Elasticsearch, I try to follow the user guides as closely as possible.
Currently I'm trying to set up a Logstash codec plugin by following this guide: https://www.elastic.co/guide/en/logstash/current/_how_to_write_a_logstash_codec_plugin.html
However I'm stuck at step 3 when copying the example code. There are no files in the downloaded repository which match the ones described in the example. Namely: the gemspec file and the two rb files.
What did I miss?
