Writing a SQL interpreter in Ruby, driven by tests.

We'll be doing this iteratively It'll go like this

  • Pick a statement to implement

  • Write an integration test

  • Figure out what the semantic model should look like for it

  • write tests for the semantic model

  • then the parser

  • then the transformer

First, we'll build a walking skeleton We'll build a tiny bit of the parser, the transformer and the semantic model

Dependencies

  • Ruby of course
  • Parslet a PEG parser combinator toolkit link
