Spectre.Console.Extensions

The goal of this project is to extend Spectre.Console plugins with some niche functionality.

• Progress with IProgress Adapter.
• Progress with automatic reporting for HttpClient.
• Table with DataTable.

Package	Version	Description
Spectre.Console.Extensions.Progress		IProgress adapter and HttpClient reporting.
Spectre.Console.Extensions.Table		DataTable and DataSet support.

Spectre.Console.Extensions.Progress

Extensions for AnsiConsole.Progress

IProgress Adapter

Use spectre spinner with standard IProgress interface.

Motivation: To plug methods that accept IProgress so that reporting is declarative, familiar, convenient.

private static async Task RunSimpleExampleAsync()
{
    await BuildProgress().StartAsync(
        GenerateProgressTasks,
        (reporter) => RunSpinnerWithIProgress(reporter, TimeSpan.FromMilliseconds(500)),
        (reporter) => RunSpinnerWithIProgress(reporter, TimeSpan.FromSeconds(1)));

    // Collection of tasks to execute,
    // every task corresponds to following delegates sequentially.
    static IEnumerable<ProgressTask> GenerateProgressTasks(ProgressContext ctx)
    {
        yield return ctx.AddTask("Task1");
        yield return ctx.AddTask("Task2");
    }

    static async Task RunSpinnerWithIProgress(
        IProgress<double> reporter,
        TimeSpan delay)
    {
        var capacity = 100;
        var step = 10;
        while (capacity > 0)
        {
            reporter.Report(step);
            capacity -= step;
            await Task.Delay(delay);
        }
    }
}

Reporting for HttpClient

Run progress for a given HttpClient and HttpRequestMessage. Result is provided as System.IO.Stream.

Motivation: It is quite a common task to download something and have a spinner for that. Basically, you don't even wanna to bother with reporting in this case.

var message = new HttpRequestMessage(HttpMethod.Get, url);
var http = new HttpClient();
var description = "Downloading cats images";
await BuildProgress().StartAsync(http, message, taskDescription: description, DownloadCallback);

static async Task DownloadCallback(Stream stream) => {};

await BuildProgress()
    .WithHttp(http, request, description, DownloadCallback1)
    .WithHttp(http, request, description, DownloadCallback2)
    .StartAsync();

Spectre.Console.Extensions.Table

Display System.Data.DataTable.

System.Data.DataTable dataTable = DataTableFactory();
var table = dataTable.FromDataTable().Border(TableBorder.Rounded);
AnsiConsole.Write(table);

TODO

• Add xml-doc for existing public APIs.
• Add statiq docs
• Add unit tests.
• Fix warnings; consider to TreatWarningsAsErrors

Examples

To see Spectre.Console in action, install the dotnet-example global tool.

> dotnet tool restore

Now you can list available examples in this repository:

> dotnet example

And to run an example:

> dotnet example iprogress
