WrapSoft

WrapSoft is a cross-platform software library and toolkit for text wrapping and line breaking. It provides algorithms to wrap text into lines of a given width, with support for hyphenation, ordinary and soft wrapping, and basic layout features. It is designed to be integrated into text editors, terminal emulators, and document processing pipelines, where consistent wrapping behavior is required across languages and scripts. The core engine emphasizes streaming capability, enabling wrap decisions to be made incrementally as text is produced or consumed.

The architecture consists of a core wrap algorithm implemented in C++, with language-agnostic bindings for Python, JavaScript, and other languages. It offers an API to wrap a sequence of characters into lines under constraints such as maximum line length, margins, and indentation. Optional modules provide hyphenation dictionaries, support for bidirectional text, and metrics for line justification. The project aims for a small, predictable footprint and deterministic results. Its modular design allows developers to replace or extend components such as the hyphenation strategy or the text metrics calculator.

WrapSoft is released under the MIT license and maintains an active development community, with release notes and issue tracking hosted on a public repository. It is used by several open-source projects seeking language-agnostic wrapping behavior and customizable wrapping policies. Limitations include performance trade-offs for very large documents and the need for language-specific dictionaries for advanced hyphenation in some languages.
