SyntaxValidatoren

SyntaxValidatoren is a software library and command-line tool designed to validate the syntax of programming languages and data formats. It provides a framework for defining formal grammars and applying them to input streams, enabling early detection of syntax errors in editors, compilers, and data validation pipelines. The project emphasizes language-agnosticism and embeddability, offering bindings and plugins to integrate into diverse development environments.

Core capabilities include grammar-based validation, precise error reporting with line and column information, and the generation of abstract syntax trees or parse trees. It supports incremental parsing for large files, streaming validation, and batch mode operation. The system handles common formats such as JSON, XML, YAML, SQL, and a range of domain-specific languages, with extensible grammars that users can tailor to project requirements. It also provides a plugin architecture for custom validators and can be integrated into continuous integration workflows and IDEs.

Architecture and design involve a modular parsing engine, a grammar repository, and language bindings. Grammars can be authored in formal notations such as EBNF or PEG, and the engine can switch between parsers to optimize performance or error diagnostics. The tool emphasizes clear, actionable error messages and tool-friendly output formats like parse trees or annotated diagnostics.

SyntaxValidatoren is released as free and open-source software under a permissive license. The project maintains a public repository with issue tracking, contribution guidelines, and release notes, reflecting an emphasis on community involvement and incremental improvement.
