MyStructures

A small collection of reusable C# data structures and algorithms: a stopwatch-style timer keyed by an enum, a two-level dictionary with default values, distinct-color generation, and a fast Levenshtein distance.

MyStructures.Timing.TimingObject<T> (where T : Enum)

A multi-operation stopwatch. Each enum value names an operation you can start, stop, and toggle independently; the object accumulates the elapsed time across all the intervals for that operation. Thread-safe.

Nested types: TimeInterval (a single start/stop span with Elapsed) and the JsonInfo struct.

enum Phase { Load, Process, Save }

var timer = new TimingObject<Phase>();
timer.Start(Phase.Load);
// ... work ...
timer.Stop(Phase.Load);
Console.WriteLine(timer.GetTotalElapsed(Phase.Load));

MyStructures.DictionaryManager

DictionaryManager<TValue>

A string-keyed dictionary that internally buckets entries by their first character, which keeps each underlying dictionary smaller when working with very large key sets. It implements IEnumerable<KeyValuePair<string, TValue>> so it can be iterated with foreach.

• Optionally constructed with a default value; otherwise missing keys are auto-created via Activator.CreateInstance<TValue>().
• Indexer get/set transparently routes to the correct first-character bucket.

DefaultDict<TKey, TValue>

A Dictionary<TKey, TValue> whose indexer auto-creates a missing key on access — either using a supplied default value or a new TValue instance — mirroring Python's collections.defaultdict.

var counts = new DefaultDict<string, int>();
counts["a"]++;   // key "a" is created automatically

MyStructures.Distances.LevenshteinDistance

int d = LevenshteinDistance.FastDistance("kitten", "sitting"); // 3

MyStructures.ColorGenerator.ColorGenerator

Generates a sequence of visually distinct RGB hex colors (without the leading #). It cycles through seven channel patterns and walks intensity values down a binary tree so that successive colors stay far apart in color space — handy for assigning colors to categories, chart series, highlight groups, etc.

Supporting types — PatternGenerator, IntensityGenerator, IntensityValue, and IntensityValueWalker — implement the pattern selection and the intensity tree-walk behind NextColour().

var gen = new ColorGenerator();
for (int i = 0; i < 10; i++)
    Console.WriteLine("#" + gen.NextColour());
