CaseDotNet.Extensions 0.1.39

Case.NET

String manipulation library built with intention to make naming conventions conversion easy

Motivation

Suddenly, suffering from urgent need of easy and performant way to convert strings from arbitrary naming convention to camelCase, I went out searching around NuGet and found out that there are not many options available in .NET (actually one), which would be public, and not part of some parent project. I see that as a huge overlook, considering amount of such packages for other languages (JS, for example), so I decided it would be quite useful to write something which will be reliable and extensible, so here it is.

Note that library is still in development and is lacking some planned functionality (see TODO) or may contain bugs, feel free to report them in the issues section

Features

• Built-in support for all common naming conventions:
  • camelCase
  • PascalCase
  • snake_case
  • kebab-case
  • See supported conventions for full list
• Easily extensible:
  • Modular design - combine different types of parsers, word emitters, concatenators, etc. to build the converter you need
  • Modules are dead simple to implement
• Performant:
  • Default modules' implementation aims to be as much GC-friendly as possible
  • No Regex usage, tokenization done by simple condition-based lexers choosing leftmost overlapped sequence (smallest possible token size is chosen)
• Zero dependencies:
  • Keeping your application size as low as possible by avoiding third party library bloat
• Portable:
  • Targets NetStandard2.0, allowing references from .NET Core 2.0 or greater and .NET Framework 4.6.1 or greater
  • Targets NetStandard2.1, allowing references from .NET Core 3.0 or greater

Warning

Default Case.NET.Parsing.Parser implementation is not thread-safe in netstandard2.0 build while it is in netstandard2.1. Thus it's recommended to have a Parser instance for each thread, if your project is targeting .NET Framework, or .NET Core 2.0-2.2

For the same reason Parser.Universal is a property, returning new instance every call in netstandard2.0, while it is a static field in netstandard2.1

Usage

NuGet package is listed under name of CaseDotNet since Case.NET was reserved

Installation

Install-Package CaseDotNet -Version 0.3.0

Include namespace

using Case.NET

Using built-in converters

Class Case.NET.CaseConverter contains static fields with built-in converters under corresponding names:

static void Main(string[] args) {
  CasedString converted = CaseConverter.CamelCase.ConvertCase("not_camel_case");

  Console.WriteLine((string)converted); // notCamelCase
}

Currently supported conventions (as target)

• camelCase
• PascalCase
• snake_case
• CONSTANT_CASE
• kebab-case
• Train-Case

TODO

Target conventions to support

• Capital Case
• dot.case
• Namespace.Case
• no case
• path/case (With optional backslash \ as delimiter)
• Sentence case
• Title Case
• Swap case (Change case of every character) Swap Case → sWAP cASE
• FeNcE CaSe
• SPonGE CasE
• reVERse spONge cASe
• RanDOM CAse

Misc

• Improve unit test coverage
