@ -5,6 +5,14 @@ An attempt at simple staged metaprogramming for c/c++.
The library API is a composition of code element constructors.
These build up a code AST to then serialize with a file builder.
General goal is to have a less than 15k sloc library that takes at most a couple of hours to learn and make use of.
*Why 15?* Assuming a seasoned coder of C++ can read and understand around 1000-2000 lines of code per hour, 15,000 could be understood in under 16-18 hours
and have confidence in modifying for their use case.
This code base attempts follow the [handmade philosophy](https://handmade.network/manifesto),
its not meant to be a black box metaprogramming utility, its meant for the user to extend for their project domain.

* *Upfront constructors are not necessarily used in the parsing constructors, this is just a good metric to know what can be parsed.*

`def_operator` is the most sophisticated constructor as it has multiple permutations of definitions that could be created that are not trivial to determine if valid.
If extendeding parsing capability
If extendeding parsing capability, ECode, ESpecifier, may need to be modified along with making a new `AST_<Name>` and `Code<Name>` if its desired to preserve the same interface. The lexer (see the `Parser` namespace in `gen.cpp`) will most likely also need to be extended to support any unsupported or custom tokens.
