I Hate Regex
i-hate-regex is a suite of interactive utilities for constructing, validating, configuring, and visualizing regular expressions. It provides a specialized environment for regular expression construction and debugging, allowing users to build complex patterns and verify matching behavior through interactive testing.
The project features a regular expression generator with a real-time matching preview and a visual representation tool that displays the logical structure of a pattern. It also includes a curated library of standardized patterns for common data formats, including email addresses, IP addresses, phone numbers, dates, and social security numbers.
The toolset covers regex syntax validation and flag configuration for global, case-insensitive, and multiline behaviors. It also supports the embedding of its visualization components into external websites.
Features
- Regular Expression Playgrounds - Provides an interactive playground for building and testing complex regex patterns with real-time previews.
- Regular Expression Visualizers - Provides a visual representation tool that displays the logical structure of a regular expression to help users understand pattern behavior.
- Regex Pattern Syntax Validations - Checks for errors in regular expression code and uses highlighting to identify problematic segments.
- Debugging Tools - Analyzes existing regex patterns through visualization and syntax validation to identify unexpected matching behavior.
- Regex Visualizers - Provides visual diagrams of regular expression patterns to help users understand the matching logic.
- Regex Pattern Validators - Verifies that regular expression patterns correctly match specific test strings before deployment.
- Live Preview Renderers - Updates matching results in real time as the user modifies the regex pattern or sample text.
- Regex Pattern Catalogs - Includes a curated catalog of regular expressions for common data formats like emails and IP addresses.
- Social Security Number Validators - A pre-defined regular expression pattern for verifying strings against the NNN-NN-NNNN format while enforcing government restrictions.
- Date Validation Utilities - A collection of regular expression patterns used to identify date strings across various separators and day-month-year sequences.
- Phone Number Pattern Matching - A generalized regular expression for matching phone numbers with optional country codes, dashes, and whitespace.
- Regex Pattern Catalogs - Stores a predefined library of common regular expression patterns and descriptions in JSON files for quick lookup.
- Regular Expression Generators - Generates regular expression patterns based on specific constraints with a real-time matching preview.
- Regex Syntax References - Provides a comprehensive guide to common patterns and character classes for standard data formats.
- Format Validations - A set of regular expression patterns for verifying various IPv6 address formats, including compressed and mapped notations.
- Regex Flags - Allows users to toggle global, case-insensitive, and multiline flags to modify regex evaluation.
