# C++20 preprocessor of C++ written in Rust
### Description
Module dependency tree generation is done!
This is a very simple and most certainly wrong preprocessor for C++. This was not done with any major intents, it was simply to test Rust and its capabilities (I find learning by doing a lot more useful than just following tutorials).
As a rust novice, I do not claim this to be of any quality.
So far, the most rellevant missing things are:
- the #line directive is not supported (and probably won't for some time, I do not intend to support generated code for now :) )
- QOL Features of preprocessors, like any pragma directive (none mandated by standard, but #pragma once is expected from any sensible implementation), or the `__FUNCTION__` macro (which requires the step 7 parser to be implemented in order to know such information)
- Most test macros are kinda useless right now. `__has_cpp_attribute` is literally just hardcoded to 0
I'd say that the first 4 steps of the compilation process of C++ are done-ish! Time for lexing.
If you want more logs on what's going on, you can use the environment varaible `RUST_LOG`, like so: `RUST_LOG=debug`
