EchoSpec

Build & Publish NuGet NuGet License: MIT .NET

A zero-dependency .NET library for turning tabular data into Console, Markdown, HTML, or custom output from a single source.

  • Fluent TableBuilder and ReportBuilder<T>
  • Built-in Console, Markdown, and HTML renderers
  • Extend via ITableRenderer / IReportRenderer

Installation

dotnet add package EchoSpec

Or add a PackageReference and set Version to the current release on NuGet.

Quick example

using EchoSpec;
using EchoSpec.Builders;

var table = new TableBuilder()
    .AddHeader("Name")
    .AddHeader("Score", ColumnAlignment.Right)
    .AddRow("Alice", "95")
    .AddRow("Bob", "87");

Console.WriteLine(table.Build(ReportFormat.Console));
File.WriteAllText("results.md", table.Build(ReportFormat.Markdown));
File.WriteAllText("results-table.html", table.Build(ReportFormat.Html)); // <table> fragment

Name   Score
─────────────
Alice     95
Bob       87

Reports over typed data:

var builder = new ReportBuilder<TestResult>()
    .WithTitle("Test Results")
    .AddTable((table, data) =>
    {
        table.AddHeader("Test")
             .AddHeader("Status", ColumnAlignment.Center);
        foreach (var row in data)
            table.AddRow(row.Name, row.Passed ? "✓" : "✗");
    })
    .AddSection(data => $"Total: {data.Count()} tests");

var output = builder.Generate(results, ReportFormat.All);
output.WriteToConsole();
output.SaveMarkdown("results.md");
output.SaveHtml("results.html"); // full HTML document

Gotchas

Topic Detail
Table HTML Build(ReportFormat.Html) / BuildWith(new HtmlRenderer()) → <table> fragment
Report HTML Generate(ReportFormat.Html) / GenerateWith(..., new HtmlRenderer()) → full document
TableBuilder.Build Single formats only (Console, Markdown, Html). All throws — use BuildWith
Console + Markdown only GenerateWith / BuildWith with those two renderers (no Both enum)
BuildWith / GenerateWith One renderer → string; params → IReadOnlyDictionary<string, string> keyed by Name
Duplicate Name Throws — renderer names must be unique
Row widths Default pad/truncate to header count; set StrictRowWidths = true to throw
