🚀 Quick Start

Installation

bash gem install textstat

Or add to your Gemfile:

ruby gem 'textstat', '~> 1.0'

Basic Usage

```ruby require 'textstat'

text = "This is a sample text for readability analysis. It contains multiple sentences with varying complexity levels."

Basic statistics

TextStat.charcount(text) # => 112 TextStat.lexiconcount(text) # => 18 TextStat.syllablecount(text) # => 28 TextStat.sentencecount(text) # => 2

Readability formulas

TextStat.fleschreadingease(text) # => 45.12 TextStat.fleschkincaidgrade(text) # => 11.2 TextStat.gunningfog(text) # => 14.5 TextStat.textstandard(text) # => "11th and 12th grade"

Difficult words (with automatic caching)

TextStat.difficult_words(text) # => 4 ```

🌍 Multi-Language Support

TextStat supports 22 languages with optimized dictionary caching:

```ruby

English (default)

TextStat.difficultwords("Complex analysis", 'enus')

Spanish

TextStat.difficult_words("Análisis complejo", 'es')

French

TextStat.difficult_words("Analyse complexe", 'fr')

German

TextStat.difficult_words("Komplexe Analyse", 'de')

Russian

TextStat.difficult_words("Сложный анализ", 'ru')

Check cache status

TextStat::DictionaryManager.cachesize # => 5 TextStat::DictionaryManager.cachedlanguages # => ["en_us", "es", "fr", "de", "ru"] ```

Supported Languages

| Code | Language | Status | Code | Language | Status | |------|----------|--------|------|----------|--------| | en_us | English (US) | ✅ | fr | French | ✅ | | en_uk | English (UK) | ✅ | es | Spanish | ✅ | | de | German | ✅ | it | Italian | ✅ | | ru | Russian | ✅ | pt | Portuguese | ✅ | | pl | Polish | ✅ | sv | Swedish | ✅ | | da | Danish | ✅ | nl | Dutch | ✅ | | fi | Finnish | ✅ | ca | Catalan | ✅ | | cs | Czech | ✅ | hu | Hungarian | ✅ | | et | Estonian | ✅ | id | Indonesian | ✅ | | is | Icelandic | ✅ | la | Latin | ✅ | | hr | Croatian | ⚠️ | no2 | Norwegian | ⚠️ |

Note: Croatian and Norwegian have known issues with the text-hyphen library.

⚡ Performance Optimization

Dictionary Caching (New in 1.0.0)

TextStat now caches language dictionaries in memory for massive performance improvements:

```ruby

First call loads dictionary from disk

TextStat.difficultwords(text, 'enus') # ~0.0047s

Subsequent calls use cached dictionary

TextStat.difficultwords(text, 'enus') # ~0.0013s (36x faster!)

Cache management

TextStat::DictionaryManager.cachesize # => 1 TextStat::DictionaryManager.cachedlanguages # => ["enus"] TextStat::DictionaryManager.clearcache # Clear all cached dictionaries ```

Memory Usage

• Efficient: Each dictionary ~200KB in memory
• Scalable: Cache multiple languages simultaneously
• Manageable: Clear cache when needed

📊 Complete API Reference

```ruby

Character and word counts

TextStat.charcount(text, ignorespaces = true) TextStat.lexiconcount(text, removepunctuation = true) TextStat.syllablecount(text, language = 'enus') TextStat.sentence_count(text)

Averages

TextStat.avgsentencelength(text) TextStat.avgsyllablesperword(text, language = 'enus') TextStat.avgletterperword(text) TextStat.avgsentenceperword(text)

Advanced statistics

🏗️ Architecture (New in 1.0.0)

TextStat 1.0.0 features a clean modular architecture:

Modules

• TextStat::BasicStats - Character, word, syllable, and sentence counting
• TextStat::DictionaryManager - Dictionary loading and caching with 36x performance boost
• TextStat::ReadabilityFormulas - All readability calculations and text standards
• TextStat::Main - Unified interface combining all modules

Backward Compatibility

All existing code continues to work unchanged:

```ruby

This still works exactly the same

TextStat.fleschreadingease(text) # => 45.12 TextStat.difficult_words(text) # => 4 (but now 36x faster!) ```
