Extending the fuzzer from Diverse project to give the possibility to generate random card directly from the IFuzz interface.

Cardizer should be able to use the random from the Fuzzer to be sure the same seed is used.

Hi!

Let's use docfx to generate a static documentation for Cardizer.

DocFX is an API documentation generator for .NET, which currently supports C#, VB and F#. It generates API reference documentation from triple-slash comments in your source code. It also allows you to use Markdown files to create additional topics such as tutorials and how-tos, and to customize the generated reference documentation. DocFX builds a static HTML website from your source code and Markdown files.

Then to we could host it on a web server (for example, github.io).

Hi!

Why bother generating RELEASE_NOTES.md when GitHub to the job?

To do list:

• Remove RELEASE_NOTES.md file
• Replace lib's link with https://github.com/d-edge/Cardizer/releases/

I did not see any specific list functionality (at least in the main part of the library). It could be better to change the core logic to Seq. This issue followed a quick exchange with @torendil. Thank you for the idea.

Hello,

While @fighou was working on the RuPay card (#34), the card was updated on the Wikipedia's page. You can view the diff.

So, what could we do to assert that values are up-to-date? Would it be possible to have a bot who check for wiki edit on the Payment card number. Is such a bot do exist or should we create one? How could we tackle that?

Hello,

I wanted to start playing with FsCheck for a while. i will let FsCheck introduce itself:

FsCheck is a tool for testing .NET programs automatically. The programmer provides a specification of the program, in the form of properties which functions, methods or objects should satisfy, and FsCheck then tests that the properties hold in a large number of randomly generated cases. While writing the properties, you are actually writing a testable specification of your program. Specifications are expressed in F#, C# or VB, using combinators defined in the FsCheck library. FsCheck provides combinators to define properties, observe the distribution of test data, and define test data generators. When a property fails, FsCheck automatically displays a minimal counter example.

I will start a branch about it next Thursday.

Thank you @thinkbeforecoding for mentioning it and /u/Frozen_Turtle to mentioning again. Lets do it!

An F# type provider is a component that provides types, properties, and methods for use in your program. Type Providers generate what are known as Provided Types, which are generated by the F# compiler and are based on an external data source.

The goal would be to move all the card's data from the code to the external json.

Hi!

I think for testing purpose, being able to seed the randomization could be useful. This would help fix issue raised on #83

The Random logic is in next and was based on a snippet by @tpetricek

    static member private next =
        let seedGenerator = Random()

        let localGenerator =
            new ThreadLocal<Random>(fun _ ->
                lock
                    seedGenerator
                    (fun _ ->
                        let seed = seedGenerator.Next()
                        Random(seed)))

        fun n -> localGenerator.Value.Next(n)

Random() can be seeded by passing a parameter Random(seed).

In the NextVerve function we are doing:

let prefixes, state =
    nextInRange prefix.[0] prefix.[1]
    |> numberToSeq

where numberToSeq is defined as nested function like this:

let inline charToInt c = int c - 48
let numberToSeq n = n |> string |> Seq.map charToInt

This implementation was a first step to make it work. Now it is time to improve it a bit. @torendil remember me that we can achieve the same result by dividing and moduling by 10. Here is the alternative:

let itois number =
    let rec loop n list = 
        if n <= 0 then list
        else loop (n / 10) (n % 10 :: list)
    loop number []

Try it online!

The function's name is a souvenir my C days. We don't have to keep it.

open System

open BenchmarkDotNet.Attributes
open BenchmarkDotNet.Running
open BenchmarkDotNet.Jobs

let itois number =
    let rec loop n list = 
        if n <= 0 then list
        else loop (n / 10) (n % 10 :: list)
    loop number []

let inline charToInt c = int c - 48
let numberToSeq n = n |> string |> Seq.map charToInt

[<SimpleJob (RuntimeMoniker.NetCoreApp50)>]
type Benchmarks() =
    [<Params(100, 1000, 10000, 100000, 1000000)>]
    member val size = 0 with get, set

    [<Benchmark>]
    member this.itois () = itois 506100
    [<Benchmark(Baseline = true)>]
    member this.numberToSeq () = numberToSeq 506100 |> Seq.length

BenchmarkRunner.Run<Benchmarks>() |> ignore

The result is quite clear in favor of itois:

If you have any other ideas to improve this part. Feel free to comment below.

Thank you @torendil :)
