An attempt at simple staged metaprogramming for c/c++.
|
||||
|
||||
This library is intended for small-to midsize projects that want rapid complation times.
|
||||
for fast debugging.
|
||||
|
||||
## Notes
|
||||
|
||||
This project is not minimum feature complete yet.
|
||||
Version 1 will have c and a subset of c++ features available to it.
|
||||
|
||||
I will generate with this library a C99 or 11 variant when Version 1 is complete.
|
||||
A single-header version will also be genrated.
|
||||
|
||||
## How it works
|
||||
|
||||
A metaprogram is built to generate files before the main program is built. We'll term runtime for this program as `gen_time`. The metaprogram's core implementation are within `gen.hpp` and `gen.cpp` in the project directory.
