 ''''Rule-Based NLP with NLP++: A practical guide to rule-based text analysis with VisualText'''' is the first full-length textbook on the language, written by its creators [[David de Hilster]] and [[Amnon Meyers]] and published by [[BPB Publications|BPB Online]] in 2026 (396 pages; print ISBN 978-93-65891-98-0, eBook ISBN 978-93-65890-08-2). The book teaches the complete development lifecycle of a text analyzer — designing multi-pass analyzers in [[VisualText]], writing grammar rules and managing parse trees, and building real-world capabilities such as date-time recognition, named-entity extraction, and coreference resolution — as well as integrating NLP++ analyzers with Python, TypeScript, C++, and the HPCC Systems big-data platform. It is aimed at software engineers, computational linguists, NLP researchers, and students with basic programming experience; no prior NLP knowledge is assumed. A companion web presence for the book is maintained at [https://book.visualtext.org book.visualtext.org].

The long-term plan is to take ownership of the .nlp extension for NLP++ given it is the only computer language exclusively dedicated to natural languaage.

	==== ~~VisualText~~ Version 3 ====		==== Version 3 of the NLP Engine ====
	~~A new~~ '''Version 3''' of ~~VisualText~~, ~~announced in 2026~~, ~~builds~~ on ~~the VSCode extension~~ and ~~adds~~ '''~~compiled~~ analyzers''' (~~for faster~~ execution and ~~for distributing~~ "protected" code ~~whose rules are not exposed)~~, ~~together with options for~~ '''cloud-based ~~deployment~~''' ~~of analyzers~~. The website ~~also~~ documents an "Using Claude with NLP++" workflow that walks developers from initial setup through ~~building~~ and deploying an analyzer with the help of an AI assistant.		'''Version 3''' is the current line of the NLP Engine and VSCode extension (releases reached v3.7.x by July 2026). It has been characterized by its authors as "compiled, cloud-built, on npm — and AI-assisted," and introduces several major capabilities:

			* '''Compiled analyzers.''' An NLP++ analyzer — and its [[Conceptual Grammar]] knowledge base — can be translated to C++ and built into native shared libraries that the engine loads at run time. From engine 3.1.44 onward, the full analyzer body runs from native shared libraries on Linux and macOS. Compilation is exposed through engine options: <code>-COMPILE</code> compiles both the analyzer and the KB to C++, <code>-COMPILEKB</code> compiles only the knowledge base (without loading the grammar or running the analyzer), and <code>-COMPILEANA</code> compiles only the analyzer. Version 3.1 added the KB-only compile path and a compiled-KB run mode.
			* '''Faster execution and source-code protection.''' Because a compiled analyzer executes pre-generated, natively compiled C++ rather than interpreting rules at run time, it runs faster; it also lets developers deliver "protected" analyzers to customers without exposing the original NLP++ rules. Standalone executables can be invoked with a <code>/COMPILED</code> flag to run the compiled build, or <code>/INTERP</code> to run the interpreted version.
			* '''Cloud build and npm distribution.''' Version 3 adds cloud-based building of analyzers, and the VSCode NLP++ extension is distributed through the npm ecosystem.
			* '''AI-assisted development.''' The website documents a "Using Claude with NLP++" workflow that walks developers from initial setup through authoring, testing, and deploying an analyzer with the help of an AI coding assistant — while keeping the resulting logic in human-readable, auditable NLP++ code.

	'''NLP++''' is a computer programming language for natural language processing created by [[Amnon Meyers]] and [[David de Hilster]] in 1998 based on a cognitive model of how humans read and understand natural language. It operates on an input text via multiple passes that elaborate a best-first parse tree. It can access and update a hierarchical knowledge base management system (KBMS) called [[Conceptual Grammar]] (CG). NLP++ and CG deploy with an Integrated Development Environment (IDE) called [[VisualText]], which supports rapid development of text analyzers.
