### High performance case transformation utility methods

## Installation

```

dotnet add package Soenneker.Utils.Case

```

## Usage

```csharp

using Soenneker.Utils.Case;

```

All conversions use a single tokenizer internally, then format into the target case.

### Core methods

- `ToKebab(ReadOnlySpan)`

- `ToSnake(ReadOnlySpan)`

- `ToUpperSnake(ReadOnlySpan)`

- `ToDot(ReadOnlySpan)`

- `ToFlat(ReadOnlySpan)`

- `ToPath(ReadOnlySpan)`

- `ToSpace(ReadOnlySpan)`

- `ToTrain(ReadOnlySpan)`

- `ToPascal(ReadOnlySpan)`

- `ToCamel(ReadOnlySpan)`

- `ToTitle(ReadOnlySpan, CultureInfo? culture = null)`

- `ToTitle(string? value, CultureInfo? culture = null)`

- `NormalizeKebab(ReadOnlySpan)`

### Example

```csharp

const string input = "HTTPServer_v2 parser";

CaseUtil.ToKebab(input);      // "http-server-v2-parser"

CaseUtil.ToSnake(input);      // "http_server_v2_parser"

CaseUtil.ToUpperSnake(input); // "HTTP_SERVER_V2_PARSER"

CaseUtil.ToDot(input);        // "http.server.v2.parser"

CaseUtil.ToFlat(input);       // "httpserverv2parser"

CaseUtil.ToPath(input);       // "http/server/v2/parser"

CaseUtil.ToSpace(input);      // "http server v2 parser"

CaseUtil.ToTrain(input);      // "HTTP-Server-V2-Parser"

CaseUtil.ToPascal(input);     // "HTTPServerV2Parser"

CaseUtil.ToCamel(input);      // "httpServerV2Parser"

CaseUtil.ToTitle(input);      // "HTTP Server V2 Parser"

```
