lorina is a C++ parsing library. It provides implementations of parsers for various simple file formats used in logic synthesis and formal verification.

Read the full documentation.


The following code snippet parses the bench file "network.bench" and calls the methods on_input and on_gate for each input and gate declaration in the file, respectively.

#include <lorina/lorina.hpp>

class reader : public bench_reader
  void on_input( const std::string& name ) const override
    /* ... */

  void on_gate( const std::vector<std::string>& inputs, const std::string& output,
                const std::string& type ) const override
    /* ... */
}; /* reader */

auto const result = read_bench( "network.bench", reader() );
assert( result == return_code::success );

Besides parsing, the reader supports a mechanism to react on parse errors.

#include <lorina/diagnostics.hpp>

class diagnostics : public diagnostic_engine
  void emit( diagnostic_level level, const std::string& message ) const override
    /* ... */
}; /* diagnostics */

diagnostics diag;
auto const result = read_bench( "network.bench", reader(), &diag );
assert( result == return_code::success );
