EnumerablePrinter 1.0.6

EnumerablePrinter

Python-inspired LINQ extensions for expressive, ergonomic collection handling in C#.

EnumerablePrinter brings the clarity and power of Python’s sequence operations to C#, with intuitive methods like Slice, Print, and IsAlphabetical. Designed for developer ergonomics, deferred execution, and clean diagnostics.

✨ Latest Updates

• Dictionary Support – Print key/value pairs inline for easy readability.
• Nested Collections – Recursively prints arrays, lists, and sets without duplication.
• Char Enumerable Special Case – IEnumerable<char> now prints as a string literal instead of a collection.
• Custom Formatting – User‑provided delegates are respected, even for strings.
• Output Redirection – Send output to any TextWriter (console, file, or in‑memory).

✨ Features

🚀 Installation

dotnet add package EnumerablePrinter

🧪 Test

dotnet test

Sample expectation:

Enumerable.Empty<int>().Print();
// Output: { }

🧰 Usage

Add using EnumerablePrinter; at the top of your file, and you're good to go.

➤ Basic Usage

new[] { 1, 2, 3 }.Print();
// Output: { 1, 2, 3 }

➤ Empty Collections

Enumerable.Empty<int>().Print();
// Output: { }

➤ Printing a Dictionary

var dict = new Dictionary<string, int>
{
    ["Wayne"] = 1,
    ["Lucius"] = 2,
    ["Alfred"] = 3
};
dict.Print();
// Output:
// { Wayne: 1, Lucius: 2, Alfred: 3 }

➤ Printing Nested Collections

var nested = new List<int[]>
{
    new[] { 1, 2 },
    new[] { 3, 4 }
};

nested.Print();
// Output:
// { { 1, 2 }, { 3, 4 } }

➤ Combining Dictionaries and Nested Collections

var complex = new Dictionary<string, object>
{
    ["Numbers"] = new[] { 1, 2, 3 },
    ["Matrix"] = new List<int[]>
    {
        new[] { 1, 2 },
        new[] { 3, 4 }
    }
};
complex.Print();
// Output:
// { Numbers: { 1, 2, 3 }, Matrix: { { 1, 2 }, { 3, 4 } } }// Output:

➤ With Custom Formatting

var names = new List<string> { "Wayne", "Lucius", "Alfred" };
names.Print(n => $"[{n}]");
// Output: { [Wayne], [Lucius], [Alfred] }

➤ Redirecting Output (e.g. to logs or buffer)

using var writer = new StringWriter();
names.Print(n => n.ToUpper(), writer);
Console.WriteLine(writer.ToString());
// Output: { WAYNE, LUCIUS, ALFRED }

➤ IsAlphabetical Example

var names = new[] { "Alice", "Bob", "Charlie" };
names.IsAlphabetical(); // true
var unsorted = new[] { "Charlie", "Alice", "Bob" };
unsorted.IsAlphabetical(); // false

var people = new[]
{
    new Person { Name = "Alice" },
    new Person { Name = "Bob" },
    new Person { Name = "Charlie" }
};
people.IsAlphabetical(p => p.Name); // true

➤ Slice Example

var data = Enumerable.Range(1, 10);

data.Slice(2, 8);        // 3, 4, 5, 6, 7, 8
data.Slice(-3, null);    // 8, 9, 10
data.Slice(0, null, 2);  // 1, 3, 5, 7, 9
