A parser combinator library for F# that enables building recursive-descent parsers for formal grammars.
FParsec is a parser combinator library for F# that enables developers to build recursive-descent parsers for formal grammars. It solves the problem of parsing structured text, such as custom languages or data formats, by providing a composable and efficient API. The library supports context-sensitive grammars, Unicode, and large files while generating readable error messages.
F# developers who need to parse custom text formats, implement domain-specific languages, or process structured data from text sources. It is particularly useful for those working on compilers, interpreters, data transformation tools, or complex text analysis applications.
Developers choose FParsec for its high performance, simple yet powerful API, and excellent error reporting. Its support for infinite look-ahead grammars and Unicode, combined with comprehensive documentation, makes it a robust alternative to hand-written parsers or less optimized libraries.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Enables parsing of complex formal grammars with infinite look-ahead and context-sensitive rules, as highlighted in the README's feature list.
Automatically generates clear and informative error messages, which simplifies debugging and improves developer productivity.
Fully supports Unicode text parsing for international applications and is optimized to handle very large files with minimal memory overhead.
Thoroughly optimized implementation ensures fast parsing performance, making it suitable for demanding text processing tasks.
Limited to F# projects, making it unusable in polyglot environments or for teams standardized on other programming languages.
Lacks out-of-the-box parsers for standards like JSON or XML, requiring manual implementation or integration with additional libraries.
Requires understanding of parser combinators and formal grammars, which can be challenging for developers new to parsing or F#.
