Ed_ 050b00f28a WIP - Broken Compile : Added pragma once and includes to all files + Parser fixes, and String improvements 
Adding the pragma once and includes the files broke compilation, still diagnosing why.

- Some string functions were moved to the cpp, still need to do some more evaluation of it and the containers...
- Added support for forceinline and neverinline to parsing (untested)
- Added support for specifiers in operator cast such as explicit, inline/forceinline/neverinline, etc.
    - Before it only support const.
    - Still need to support volatile.
- Forceinline was not supported at all for tokenization, fixed that.

Documentation

The library is fragmented into a series of headers and source files meant to be scanned in and then generated to a tailored format for the target gen files.

The principal (user) files are gen.hpp and gen.cpp.
They contain includes for its various components: components/<component_name>.<hpp/cpp>

Dependencies are bundled into gen.dep.<hpp/cpp>.
Just like the gen.<hpp/cpp> they include their components: dependencies/<dependency_name>.<hpp/cpp>

The fle processors are in their own respective files. (Ex: file_processors/<file_processor>.<hpp/cpp> )
They directly include depedencies/file_handling.<hpp/cpp> as the core library does not include file processing by defualt.

TODO : Right now the library is not finished, as such the first self-hosting iteration is still WIP
Both libraries use pre-generated (self-hosting I guess) version of the library to then generate the latest version of itself.

The default gen.bootstrap.cpp located in the project folder is meant to be produce a standard segmented library, where the components of the library
have relatively dedicated header and source files. Dependencies included at the top of the file and each header starting with a pragma once.
The output will be in the project/gen directory (if the directory does not exist, it will create it).

Use those to get a general idea of how to make your own tailored version.

Feature Macros:

  • GEN_DEFINE_ATTRIBUTE_TOKENS : Allows user to define their own attribute macros for use in parsing.
    • This is auto-generated if using the bootstrap or single-header generation
    • Note: The user will use the AttributeTokens.csv when the library is fully self-hosting.
  • GEN_DEFINE_LIBRARY_CORE_CONSTANTS : Optional typename codes as they are non-standard to C/C++ and not necessary to library usage
  • GEN_DONT_ENFORCE_GEN_TIME_GUARD : By default, the library ( gen.hpp/ gen.cpp ) expects the macro GEN_TIME to be defined, this disables that.
  • GEN_ENFORCE_STRONG_CODE_TYPES : Enforces casts to filtered code types.
  • GEN_EXPOSE_BACKEND : Will expose symbols meant for internal use only.
  • GEN_ROLL_OWN_DEPENDENCIES : Optional override so that user may define the dependencies themselves.

On multi-threading

Currently unsupported.

Extending the library

This library is relatively very small, and can be extended without much hassle.

The convention you'll see used throughout the interface of the library is as follows:

  1. Check name or parameters to make sure they are valid for the construction requested
  2. Create a code object using make_code.
  3. Populate immediate fields (Name, Type, ModuleFlags, etc)
  4. Populate sub-entires using add_entry. If using the default serialization function to_string, follow the order at which entires are expected to appear (there is a strong ordering expected).

Names or Content fields are interned strings and thus showed be cached using get_cached_string if its desired to preserve that behavior.

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.

The library has its code segmented into component files, use it to help create a derived version without needing to have to rewrite a generated file directly or build on top of the header via composition or inheritance. When the scanner is implemented, this will be even easier to customize.
