Yesod-Raml:

Yesod-Raml makes routes definition from RAML File.

RAML style routes definition is inspired by sbt-play-raml.

Usage

Use parseRamlRoutes or parseRamlRoutesFile in instead of parseRoutes or parseRoutesFile.

Write RAML with handler-tag for Yesod Handler.

handler-tag is not a tag of RAML spec but original one.

You can use description-tag with handler: <<handler-name>> instead of handler-tag.

Bracket variable(PathPiece) like {hogehoge} is capitalized. The variable becomes #Hogehoge. because variable(PathPiece) of yesod-routes is data-type like String or Text.

Examples are below.

type Userid = String

mkYesod "App" [parseRamlRoutes|
#%RAML 0.8
title: Hoge API
baseUri: 'https://hoge/api/{version}'
version: v1
protocols: [ HTTPS ]
/user:
  /{userid}:
# handler tag is used.
    handler: HogeR
    get:
      description: Get user list
    /del:
# handler is written in description-tag
      description: |
	    handler: Hoge2R
      post:
        description: Delete user
|]

This is the same as following codes.

As you can see, {userid} becomes #Userid.

type Userid = String

mkYesod "App" [parseRoutes|
/api/v1/user/#Userid HogeR GET
/api/v1/user/#Userid/del Hoge2R POST
|]
