Spinner

A simple language for creating web applications inspired by the simplicity of Sinatra. It then takes that simplicity and attempt to make it even simpler. No fluff, no cruft, just your app.

The route is made up of the following parts.

The methods
The path
The headers
The return status
The return value

Everything there is optional except the return value. The return value can be plain text (surrounded by quotes), json array, json object, or html/xml. It could also be a value returned from a function defined with the fn keyword.

Default Values

When methods is absent, it defaults to get, post
When routes is absent, it defaults to /
when status is absent, it defaults to 200 OK
A Content-Type header is automatically added and its value depends on the return value.

When the return value is a json object or array, Content-Type is application/json. When it's html, the Content-Type is text/html, and text/plain when it's plain text. It should be noted that Spinner listens on Port 8000 by default. So the following is a really short - and complete - spinner application:

{ message: "Hello, Avatar" }

In the above above example, because

The methods list is absent, it defaults to get, post. That's the get method and the post method.
The route is absent, it defaults to /.
The return status is absent, it defaults to 200 OK.

Also, because a json object is returned, the Content-Type header is set to application/json.

The following is an example which returns an html on a get request for /lake_laogai with a 403 (forbidden) status

get /lake_laogai 403
<html>
  <head>
    <title>Forbidden</title>
   </head>
   <body><p>Long Feng forbids you from entering here</p></body>
</html>

Because it returns an html, the Content-Type header is set to text/html.
The following will do the same thing except some information is logged and the return is done from a function. Note the use of the fn keyword used to define the function.

get /lake_laogai 403 fn{
  logger.info "Attempt to infilterate the Dai Lee"
  return
    <html>
      <head>
        <title>Forbidden</title>
      </head>
      <body><p>Long Feng forbids you from entering here</p></body>
    </html>
}

Specify the keyword nil to indicate an empty response body. When this is the case, the Content-Type header will be absent in the response and the Content-Length header would be set to 0. For example:

get, post /azula-love-interest 204 nil

In the above example, the response body for a get or post request to the route /azula-love-interest would be empty, the status would be set to 204, the Content-Type header would be absent and the Content-Length header would be set to 0.
