RiTa New version 2.6 !

RiTa^† is a free/open-source library for writing in programmable media. It provides functions for simple language processing and generation without the overhead of a full NLP or machine-learning stack. Designed to be small and easy-to-use, it runs in a variety of environments including the browser, p5.js, Processing, Node and Android. Features include an integrated scripting language (RiScript), a letter-to-sound engine, grammar and Markov-based text generation, tools for inflection, conjugation, stemming and tokenization, and analysis of English features such as part-of-speech, phonemes, syllables, and stresses. RiTa's customizable lexicon can be searched via partial matches on combinations of any of the features listed above.

^† from old Norse, meaning to mark, scratch, or scribble

RiTa Version 2

Version 2 is a full rewrite of the library that is simpler, faster, more consistent, and more easily maintained. But it is NOT backwards-compatible with programs written with version 1.x. Nearly all of the functionality of v1 is still available (plus many new features), but much of the organization has changed. Migrating an older work to v2 is generally quite straightforward (and I'm happy to help if you run into problems)...

Key Features

• Integration of the RiScript scripting language, designed specifically for writers
• Letter-to-sound engine for feature analysis of arbitrary words (with or without a lexicon)
• Smart lexicon search for words matching part-of-speech, syllable, stress and rhyme patterns
• Fast, heuristic algorithms for inflection, conjugation, stemming, tokenization, and more
• Powerful new options for generation via grammars and Markov chains

Important Changes

• Nearly all features of the library are now static functions on the RiTa object. So you can access them as RiTa.XXX(), e.g., RiTa.phones(), RiTa.tokenize(), RiTa.conjugate(), and so on. This means that there is only one object to import into your programs.
• The RiMarkov and RiGrammar objects are significantly improved, and are now accessed via the RiTa.markov() and RiTa.grammar() static functions. RiTa grammars are still compatible with JSON, but can now include all the features of RiScript.
• RiScript is a new scripting language that allows authors to integrate static text with simple generative primitives (choices, sequences, transforms, etc.). RiScript is designed specifically for writers (for example, no quotes are required for strings) and can be run via RiTa.evaluate() or included in any RiTa grammar.
• RiTa v2 is available for Java (via Maven and Github Packages) and JavaScript (via NPM and UNPKG). It is also available, of course, as a library for Processing and p5.js.
