The parser: https://github.com/tpecholt/imrad/blob/main/src/cpp_parser.h > Is the parsing part just to read it's own code it generates? It would seem so. Their hand-rolled parser handles only a subset of the language. E.g. it hard-codes recognition for stl containers, and presumably only the ones that it might emit in generated code. There's no AST built, at least not at this level. It tokenizes and lexes, and seems to leave it up to the caller to understand how to pump the parsing "state machine". AST building and codegen appears to be done in this >9000LOC file - https://github.com/tpecholt/imrad/blob/main/src/node.cpp

Perhaps one of the most mind-boggling parts of this project is it has a hand-rolled parser for the subset of C++ that it can emit. All implemented in a single header. Equal parts impressive and crazy. https://github.com/tpecholt/imrad/blob/main/src/cpp_parser.h
