Code generator for Elixir and Erlang AWS client.

The code generator uses specs from the AWS SDK for the Go programming language to generate code.

Code is generated by running the generate.exs script.

Elixir

export SPEC_PATH=../../aws/aws-sdk-go/models/apis
export TEMPLATE_PATH=priv
export ELIXIR_OUTPUT_PATH=../aws-elixir/lib/aws
mix run generate.exs elixir $SPEC_PATH $TEMPLATE_PATH $ELIXIR_OUTPUT_PATH

Erlang

export SPEC_PATH=../../aws/aws-sdk-go/models/apis
export TEMPLATE_PATH=priv
export ERLANG_OUTPUT_PATH=../aws-erlang/src
mix run generate.exs erlang $SPEC_PATH $TEMPLATE_PATH $ERLANG_OUTPUT_PATH

Each AWS API uses a specific protocol which is defined in its specification JSON file in the aws-sdk-go repository. The existing protocols are:

• json
• rest-json
• query
• rest-xml

Every one of these protocols uses HTTP in an asynchronous (request & response) fashion. They mostly differ in what Content-Type they use for the request body, whether they include parameters in the URL or in the headers, and what Content-Type should one expect in the response body.

The following table attempts to capture the specifics of each protocol:
