> A very small DSL to create an interactive cli.

### Build status

**Master Branch**

[![Build status](https://ci.appveyor.com/api/projects/status/tngsbj4u54o90fit/branch/master?svg=true)](https://ci.appveyor.com/project/Jallah/fsmenu/branch/master)

### Nuget

Inc.

### Usage

#### The DSL:

```fsharp
// Creates a new menu
let Menu = Sub

// Render sub menu
let (+>) name entry : (string * MenuEntry) = (name,entry)

// Execute action and exit
let (=>) s f = (s, Action (fun () -> f(); Exit))

// Execute action and render the previous menu
let (<+) s f = (s, Action (fun () -> f(); NavigateBack))

// Execute action and render the menu where you come frome
let (<+=) s f = (s, Action (fun () -> f(); Stay))
```

#### Example:

```fsharp

let testFunc() = 
    printfn "selected Sub Sub 3"
    printf "handle some input: "
    let input = Console.ReadLine()
    // Do some stuff with input
    ()

printfn "Use Keys: UP-Arrow DOWN-Arrow ENTER BACK-SPACE\n"

let mutable yesOrNo = ""

let test =
    Menu [
        "Item 1" => (fun () -> printf "selected Item 1")
        "Item 2" +>
           Menu [ 
               "Sub 1" +>
                       Menu [
                           "Sub Sub 1" => (fun () -> printf "selected Sub Sub 1")
                           "Sub Sub 2" +>
                                        Menu [
                                                "yes" <+ (fun () -> yesOrNo <- "--yes")
                                                "no " <+ (fun () -> yesOrNo <- "--no") ]
                           "Sub Sub 3" <+ testFunc]
               "Sub 2" => (fun () -> printf "selected Sub 2")
               "Sub 3" => (fun () -> printf "exec some command with param %s" yesOrNo)]]

render test "<--"
```

> Instead of `(fun () -> printf ...` you could pass any `unit -> unit` function.

#### Will turn into

#### Want some color ? :)

```fsharp
renderWithColoredEmphaziser test "<--" Color.Green
```

#### Here it is

![](https://github.com/nicolaiw/FsMenu/blob/master/misc/sample3.gif)

### It is also possible to emphazise the entry

```fsharp
renderWithColoredEntry test Color.Cyan
```

![](https://github.com/nicolaiw/FsMenu/blob/master/misc/sample4.gif)

### Or Both, the emphaziser and the entry

```fsharp
renderWithColoredLine test "<--" Color.Green
```

#### Another example

[Here](https://github.com/nicolaiw/FsMenu/tree/master/misc)

### Build

+ On Windows run build.cmd
+ On Linux run build.sh

### TODO ( contributes are very welcome :D )
+ Add support for multiselect list and single select list
+ Create NuGet Package using Paket
+ Clean build.fsx
+ Refactoring: The goal is too use the render funcion like `render test <| withColoredEmphaziser "<--" Color.Green` or something like that
