ktsu.TextFilter

A .NET library for filtering text using glob patterns, regular expressions, and fuzzy matching

Introduction

ktsu.TextFilter is a .NET library that provides methods for filtering text based on different filter types and match options. It supports glob patterns, regular expressions, and fuzzy matching to help you efficiently filter and search through collections of strings.

Features

• Glob Pattern Matching: Filter text using glob patterns with optional, required, and excluded tokens.
• Regular Expression Matching: Filter text using regular expressions.
• Fuzzy Matching: Rank text based on how well it matches a fuzzy pattern.
• Customizable Match Options: Match by whole string, all words, or any word.

Installation

Package Manager Console

Install-Package ktsu.TextFilter

.NET CLI

dotnet add package ktsu.TextFilter

Package Reference

<PackageReference Include="ktsu.TextFilter" Version="x.y.z" />

Usage Examples

Basic Example

using ktsu.TextFilter;

string text = "Hello, World!";
string pattern = "Hello*";

bool isMatch = TextFilter.Match(text, pattern);

Filtering Collections

using ktsu.TextFilter;

string[] texts = new string[] { "Hello, World!", "Goodbye, World!" };
string pattern = "Hello*";

IEnumerable<string> matches = TextFilter.Filter(texts, pattern);

Ranking Results

using ktsu.TextFilter;

string[] texts = new string[] { "Hello, World!", "Goodbye, World!" };
string pattern = "Hello";

IEnumerable<string> ranked = TextFilter.Rank(texts, pattern);

Advanced Usage

Match Options

You can customize how matching is performed using the MatchOptions enum:

using ktsu.TextFilter;

string text = "Hello beautiful world";
string pattern = "hello world";

// Match by any word in the pattern
bool anyWordMatch = TextFilter.Match(text, pattern, MatchOptions.AnyWord);

// Match by all words in the pattern
bool allWordsMatch = TextFilter.Match(text, pattern, MatchOptions.AllWords);

// Match the entire string
bool wholeStringMatch = TextFilter.Match(text, pattern, MatchOptions.WholeString);

Filter Types

TextFilter supports different filter types:

using ktsu.TextFilter;

string text = "Hello, World!";
string globPattern = "Hello*";
string regexPattern = "^Hello";

// Glob pattern matching
bool globMatch = TextFilter.Match(text, globPattern, filterType: FilterType.Glob);

// Regular expression matching
bool regexMatch = TextFilter.Match(text, regexPattern, filterType: FilterType.Regex);

// Fuzzy matching
bool fuzzyMatch = TextFilter.Match(text, "Helo", filterType: FilterType.Fuzzy);
