@ -27,6 +27,12 @@ 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 generated.
The size target of this library is to stay under 5000 sloc (data & interface code).
With the dependency code being under 10000 sloc. (Containers, Memory, String handling, Language bloat)
Any dependencies from the zpl library will be exposed manually with using declarations into global scope.
They will be removed when the library is feature complete for version 1 (zero dependencies milestone).
## Usage
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.

* constinit : Better than constexpr at doing its job, however, its only c++ 20.
* export : Useful if c++ modules ever come around to actually being usable.
* import : ^^
* module : ^^
These features are in as they either are not horrible when used conservatively or are a performance benefit (modules).
When it comes to excution statements:
There is no parse API for validating excution statements (possibly will add in the future, but very limited in what it can do).
This reason there isn't one: thats where the can of worms open for parsing validation.
For most metaprogramming (espcially for c/c++), expression validation is not necessary, it can be done by the compiler for the runtime program.
Most of the time, the critical complex metaprogramming conundrums are actaully producing the frame of abstractions around the expressions.
Thus its not very much a priority to add such a level of complexity to the library when there isn't a high reward or need for it.
To further this point, lets say you do have an error with an execution statment. It will either be caught by the c++ compiler when compiling the target program, or at runtime for the program.
* If its not caught by the compiler, the only downside is the error appers on the generated function. Those with knowledge of how that definition was generated know where to find the code that inlined that expression in that file for that definition.
* If its caught at runtime. The expression will be shown in a stack trace if debug symbols are enabled in the generated function body. Yet again those with knowledge of how that definition was generated know where to find the code that inlined that expression.
In both these cases will get objectively better debug information than you would normally get on most c++ compilers with complex macros or templates.
### The Data & Interface
As mentioned in [Usage](#Usage), the user is provided Code objects by calling the constructor functions to generate them or find existing matches.
The AST is managed by the library, however the user may specificy memory configuration.
Notes:
* The allocator definitions used are exposed to the user incase they want to dictate memory usage*
* ASTs are wrapped for the user in a Code struct which essentially a warpper for a AST* type.
* Both AST and Code have member symbols but their data layout is enforced to be POD types.
The AST is managed by the library and provided the user via its interface prodedures.
However, the user may specificy memory configuration.
Data layout of AST struct:

string_const Name;
string_const Comment;
CachedString Name;
CachedString Comment;
union {
array(AST*) Entries;
string_const Content;
CachedString Content;
