package json-feed

package json-spec-elm-servant

Generated elm code for servant APIs. Generate Elm encoders, decoders, and API requests for an Servant API, where the shape of the data going over the API is described using `json-spec`. See the `testtest.hs` and `testApi.hs` for an example.

json-spec-openapi This package provides a way to produce openapi3 documentation from a json-spec specification.

Example

Given this data type:

data User = User
{      name :: Text
, lastLogin :: Maybe UTCTime
}
deriving ToSchema via (EncodingSchema User) -- <-- ToSchema instance defined here
instance HasJsonEncodingSpec User where
type EncodingSpec User =
JsonObject
'[ Required "name" JsonString
, Optional "last-login" JsonDateTime
]
toJSONStructure user =
(Field @"name" (name user),
(fmap (Field @"last-login") (lastLogin user),
()))

Calling `Data.Aeson.encode (Data.OpenApi3.toSchema (Proxy :: Proxy User))` will produce the following Schema:

{
"additionalProperties": false,
"properties": {
"last-login": {
"format": "date-time",
"type": "string"
},
"name": {
"type": "string"
}
},
"required": [
"name"
],
"type": "object"
}

package kazura-queue

Fast concurrent queues much inspired by unagi-chan "kazura-queue" provides an implementation of FIFO queue. It is faster than Chan, TQueue or TChan by the benefit of fetch-and-add instruction. Main motivation of this package is to solve some difficulty of "unagi-chan" package.
- In "unagi-chan", the item in the queue/chan can be lost when async exception is throwed to the read thread while waiting for read. (Although it has handler to recover lost item, it is difficult to keep FIFO in such case)
- In "unagi-chan", garbage items of the queue cannot be collected immediately. Since the buffer in the queue has the reference to the items until the buffer is garbage-collected.
"kazura-queue" is slightly slower than "unagi-chan" instead of solving these issues. "kazura-queue" lost broadcast function to improve the second issue. It means that kazura-queue is not "Chan" but is just "Queue".
