Code generator for Elixir and Erlang AWS client.
Generating code
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. It requires Elixir 1.8.4+.
Elixir
export SPEC_PATH=../../aws/aws-sdk-go/models/apis
export TEMPLATE_PATH=priv
export ELIXIR_OUTPUT_PATH=../aws-elixir/lib/aws/generated
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
AWS Protocols
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:
| json | rest-json | query | rest-xml | |
|---|---|---|---|---|
| Methods | POST | GET, POST, PATCH, PUT, DELETE | POST | GET, POST, PATCH, PUT, DELETE |
Request Content-Type | application/json | application/json | application/x-www-form-urlencoded | text/xml |
| URL Parameters | No | Yes | No | Yes |
| Header Parameters | No | Yes | No | Yes |
Response Content-Type | application/json | application/json | text/xml | text/xml |
Dependencies
This project has some dependencies you need to install before installing packages with Hex. Here you can find instructions for Ubuntu Linux and Mac OS.
Ubuntu Linux dependencies
Two packages are needed for Ubuntu: gcc and build-essential. To install them:
$ apt-get install build-essential cmake
Mac OS X dependencies
Two similar packages are needed in OS X, but you may install them with brew:
$ brew install gcc cmake
Alternatively you can install XCode's Command Line Developer Tools package:
$ xcode-select --install
