Basic Examples  (3)

Use SquareRepeatingElement to interpret a square matrix of data:

Wolfram Language code: Interpreter[SquareRepeatingElement["Number"]][{{"1.1", "3.2"}, { "32", "22.2"}}]

SquareRepeatingElement fails on data that is not square:

Wolfram Language code: Interpreter[SquareRepeatingElement["Number"]][{{"1", "2.5", "3.2"}, {"11", "15", "12.2"}}]

Use it in an APIFunction to collect complex data:

Wolfram Language code: api = CloudDeploy @ APIFunction[ "data" -> SquareRepeatingElement["Integer"], Det[#data]&, AllowedCloudParameterExtensions -> {"json"} ]
Wolfram Language code: URLExecute[api, {"data__json" -> "[[1, 2], [3, 4]]"}]

Scope  (2)

The second argument is used to limit the size of the input:

Wolfram Language code: Interpreter[SquareRepeatingElement["Integer", 2]][{{"1", "2", "3"}, {"11", "22", "33"}, {"111", "222", "333"}}]
Wolfram Language code: Interpreter[SquareRepeatingElement["Integer", 2]][{{"1", "2"}, {"3", "4"}}]

Limit the minimum size of the array:

Wolfram Language code: Interpreter[SquareRepeatingElement["Integer", {2, 100}]][{{"1"}}]
Wolfram Language code: Interpreter[SquareRepeatingElement["Integer", {2, 100}]][{{"1", "2"}, {"3", "4"}}]

Properties & Relations  (3)

SquareRepeatingElement can be used in conjunction with any interpreter specification:

Wolfram Language code: Interpreter[SquareRepeatingElement["Integer" | "Country"]][{{"15", "burkina faso"}, {"chad", "5"}}]

Including RepeatingElement:

Wolfram Language code: Interpreter[SquareRepeatingElement[RepeatingElement["Number"]]][{{{"1", "2", "3"}, {"1"}}, {{"5", "6"}, {"7"}}}]

And CompoundElement:

Wolfram Language code: Interpreter[SquareRepeatingElement[CompoundElement[<|"country" -> "Country", "city" -> "City"|>]]][{{<|"country" -> "argentina", "city" -> "dubai"|>, <|"city" -> "bangalore", "country" -> "usa"|>}, {<|"country" -> "angola", "city" -> "lahore"|>, <|"city" -> "bangkok", "country" -> "canada"|>}}]

Possible Issues  (1)

Constructs like FormFunction and FormPage do not show a special interface for SquareRepeatingElement:

Wolfram Language code: CloudDeploy[ FormFunction["data" -> SquareRepeatingElement["Integer"], Det[#data]& ]]
