timetable-cs

NuGet License: MIT

A modern, high-performance capacity and schedule constraint evaluation engine in C# (.NET 10).

Ported from chneau/timetable (Go) and chneau/timetable-java (Java 26), with full generic math (INumber<T>) support and seamless integration with Chneau.OpenHours.

Features

  • Generic Capacity Math: Works with any numeric type (int, long, double, float, decimal) via .NET INumber<T>.
  • Immutable Timeline Design: Safe concurrency with structural sharing and state updates.
  • Schedule Constraint Integration: Pluggable IWhenable interface directly compatible with OpenHours expressions.
  • Zero-Allocation Queries: Fast capacity evaluations and constraint searches.
  • High-Performance JSON Serialization: Custom System.Text.Json converter.

Installation

dotnet add package Chneau.TimeTable

Quick Start

using Chneau.OpenHours;
using Chneau.TimeTable;

// 1. Create a timetable with an OpenHours schedule constraint
var oh = OpenHours.Parse("Mo-Fr 09:00-17:00");
var tt = new TimeTable<int>(max: 5, openHours: oh);

var mondayMorning = new DateTime(2026, 8, 24, 10, 0, 0, DateTimeKind.Utc);
var oneHour = TimeSpan.FromHours(1);

// 2. Reserve capacity
var updated = tt.Add(mondayMorning, oneHour, cap: 2);
if (updated != null)
{
    Console.WriteLine($"Reserved successfully! Current points: {updated.Count}");
}

// 3. Find the soonest available slot for a 2-hour task requiring 4 slots of capacity
DateTime? nextAvailable = tt.When(mondayMorning, TimeSpan.FromHours(2), cap: 4);
Console.WriteLine($"Next slot: {nextAvailable}");
