km-export-processor gem

The purpose of this gem is to consume the JSON that KISSmetrics exports to an S3 bucket, and transform it in a variety of useful ways.

The core features are:

• JSON compiler : Aggregates all KISSmetrics JSON files in a directory, into a single (nonstandard) file.
• JSON to JSON converter : Converts a nonstandard JSON file into standard format.
• JSON to CSV converter : Converts a nonstandard JSON file into a CSV file, where each row is an event/property/alias.
• Reimporter : Takes a nonstandard JSON file, and an API key, and sends the data in the JSON file to the product using the KMTS gem.

• Server naming scheme (named capture groups)
  • v2
• Split on only single dashes for namespacing (negative lookaround)
  • Better version (word boundaries)
• Regex to match regexes
