// This file defines public interfaces for the C++ grammar
|
|
// (pseudo/lib/cxx/cxx.bnf). It provides a fast way to access core building
|
|
// pieces of the LR parser, e.g. Grammar, LRTable, rather than parsing the
|
|
// grammar file at the runtime.
|
|
//
|
|
// We do a compilation of the C++ BNF grammar at build time, and generate
|
|
// critical data sources. The implementation of the interfaces are based on the
|
|
// generated data sources.
|
|
//
|
|
// FIXME: not everything is fully compiled yet. The implementation of the
|
|
// interfaces are still parsing the grammar file at the runtime.
