This is a work in progress, and is not likely to be of use to you, but feel free to look around if you are inquisitive.

This is currently being used to generate Elm stubs for AWS services and you can learn from this how that is done:

# Salix

Salix is a data modelling language that is designed to support code generation across many different situations. It aims to provide a fairly rich data modelling capability that can be used as the foundation to generate functional, object-oriented, database code, data interchange formats or remote APIs and their specifications.

The modelling language is split into 3 layers. Layer 1 deals with the pure modelling language. Layer 2 deals with checking that the model is well-formed and deriving information from it that is potentially of use for code generation without specifically targeting any particular code generator. Layer 3 deals with attaching additional properties to the model that enable specific code generators to work with the model to understand how to generate from it.

The name Salix comes from the Willow tree, which is a fast growing tree - code generators help you rapidly build code syntax trees.

# Release Notes

**1.0.0**
- Overall structure and language levels developed. Some templates for
generating Elm code are provided.

**2.0.0**
- Mainly the error reporting aspect has been developed.
- APIs to standardize the L2 and L3 processors were also placed around those. This makes the system more modular allowing many different implementations to be
'plugged in'. There is still some work to do in this area, around standardizing
how code generator outputs work.

**3.0.1**
- L3 code generator for JSON codings in Elm introduced.
- A few small changes to error reporting when querying properties.
- Added the L1.Basic type to RCBasic.
