Spectre.Console with F# style.

FsSpectre is a small library that extends Spectre.Console and allow to write beautiful console applications in a declarative and more F#-friendly way. It leverages Computation Expressions to create the widgets in a declarative style.

If you want to add this package to your project, execute the following command:

dotnet add package FsSpectre

If you want to build this library on your machine, execute the following commands:

git clone [email protected]:galassie/fs-spectre.git
cd fs-spectre
dotnet build

With C# + Spectre.Console:

var table = new Table();
table.AddColumn("Foo");
table.AddColumn(new TableColumn("Bar").Centered());
table.AddRow("Baz", "[green]Qux[/]");
table.AddRow(new Markup("[blue]Corgi[/]"), new Panel("Waldo"));
AnsiConsole.Write(table);

With F# + FsSpectre:

table {
    column_text ""
    column (tableColumn { header "Feature"; centerd })
    row_text [| "Baz"; "[green]Qux[/]" |]
    row [| markup { text "[blue]Corgi[/]" }; panel { content "Waldo" } |]
} |> AnsiConsole.Write

With C# + Spectre.Console:

AnsiConsole.Write(new BarChart()
    .Width(60)
    .Label("[green bold underline]Number of fruits[/]")
    .CenterLabel()
    .AddItem("Apple", 12, Color.Yellow)
    .AddItem("Orange", 54, Color.Green)
    .AddItem("Banana", 33, Color.Red));

With F# + FsSpectre:

barChart {
    width 60
    label "[green bold underline]Number of fruits[/]"
    center_label
    item "Apple" 12 Color.Yellow
    item "Oranges" 54 Color.Green
    item "Bananas" 33 Color.Red
} |> AnsiConsole.Write

To see an example, execute the Showcase.fsx with the following command (you need to build the library first):

dotnet fsi Showcase.fsx
