+### Attributes
+
+To add additional macro attributes, all that has to be done is modifying [`AttributeTokens.csv`](./enums/AttributeTokens.csv).
+
+### Specifiers
+
+To add additional macro specifiers, the following needs to be done:
+
+1. Adjust [especifier.hpp](./components/gen/especifier.hpp)
+2. Adjust [etoktype.cpp](./components/gen/etoktype.cpp)
+3. Adjust [parser_case_macros.cpp](./components/parser_case_macros.cpp)

+### Code Types
+
+These require the following to be handled to the equivalent extent as the other types:
+
+1. Adjust [ECodeTypes.csv](./enums/ECodeTypes.csv) with the new types
+2. Define a new `AST_<Name>` and `Code<Name>`. See

+6. [inlines.hpp](./components/inlines.hpp): Any inline definitions for the `struct Code<Name>` are defined here.
+7. [interface.cpp](./components/interface.hpp): Define the `Code<Name>` upfront and parsing interface.
+8. [interface.upfront.cpp](./components/interface.upfront.cpp): Define the upfront constructor implementation.

+The library is designed to be fast to compile and generate code at runtime as fast as possible on a debug build.
 Its recommended that your metaprogam be compiled using a single translation unit (unity build).
+
+## Whats with the expression / executions support #ifd and enums?
+
+The library is a *work in progress* and those are unfinished hypotheticals for adding the ability to manage or parse the AST of expresions or execution scope code.
+They are entirely untested and not meant to be used yet, futher there is no parsing support or an upfront interface for what CodeTypes are defined so far.

+## Registering macros
 
+While the registeration of macros in the meta-program's side for parsing can be considered tedius, its necessary for the parser to accurately resolve the macros intent in one pass (and it provides some hygenics by verifying that they are used as intended).
+
+The following can be used to register a macro:
+
+```c
+GEN_API void register_macro( Macro macro );
+GEN_API void register_macros( s32 num, ... );
+GEN_API void register_macros_arr( s32 num, Macro* macros );
+```
+
+The Macro typename is defined with the following in [parser_types.hpp](../base/components/parser_types.hpp):
+
+```c
+struct Macro
+{
+    StrCached  Name;
+    MacroType  Type;
+    MacroFlags Flags;
+};
+```
+
+The macro can be designated one of the following types:
+
+* `MT_Expression`: Intended to resolve to an expression expansion.
+* `MT_Statement`: Intended to resolve an statement expansion.
+* `MT_Typename`: Intended to resolve to a typename.
+
+Additioonally tthe following flags may be set:
+
+* `MF_Functional`: The macro intended to be passed arguments are at least have the calling `()` as part of its usage.
+* `MF_Expects_Body`: The parser should expect a braced-body `{ ... }` after the macro signature `<name> <params>`

+

+
+The interface for the context:
+
+* `init`: Initializtion
+* `deinit`: De-initialization.
+* `reset`: Clears the allocations, but doesn't free the memoery, then calls `init()` on `_ctx` again.
+* `get_context`: Retreive the currently tracked context.
+* `set_context`: Swap out the current tracked context.
+
+
+#### Allocato usage
+
+* `Allocator_DyanmicContainers`: Growing arrays, hash tables. (Unbounded sized containers)
+* `Allocator_Pool`: Fixed-sized object allocations (ASTs, etc)
+* `Allocator_StrCache`: StrCached allocations
+* `Allocator_Temp`: Temporary alloations mostly intended for StrBuilder usage. Manually cleared by the user by their own discretion.
+
+The allocator definitions used are exposed to the user incase they want to dictate memory usage
+
+* Allocators are defined with the `AllocatorInfo` structure found in [`memory.hpp`](../base/dependencies/memory.hpp)
+* Most of the work is just defining the allocation procedure:
+
+```cpp
+    void* ( void* allocator_data, AllocType type, ssize size, ssize alignment, void* old_memory, ssize old_size, u64 flags );

+2. All scanned or parsed code is refactored (identifiers substs) and/or formatted.
+3. Singleheader generated.
+4. Segemented headers and source generated.
+
+## Templated container generation
+
+The array and hashtable containers used across this library are generated using the following implementatioon:
+
+* [containers.array.hpp](./components/containers.array.hpp)
+* [containers.hashtable.hpp](./components/containers.hashtable.hpp)
+
+These are functionally (and interface wise) equivalent to the library's `Array<Type>` `HashTable<Type>` within [containers.hpp](../base/dependencies/containers.hpp)
+
+Both files follow the same patter of providing three procedures:
+
+* `gen_<container>_base` : Intended to be called once, defines universal "base" definitions.
+* `gen_<container>` : Called per instatiation of the container for a given set of dependent args.
+* `gen_<container>_generic_selection_interface` : Intended to be called once after all of the instantiated containers have finished generating. It will generate a set of generic selection macros as described by Macro Usage section below.
+
+A simple `<container>_DefinitionCounter` is used to know how many instantiations of the template have occured. This is used to determine how to define `GENERIC_SLOT_<ID>_<functionID>` for the generic interface along with how many slots the `_Generic` macro will need to have generated.
+
+## Macro Usage
+
+For the most part macros are kept minimal with exception to `_Generic`...  
+*(I will be explaining this thing for the rest of this seciton along with gencpp c library's usage of it)*
+
+The `_Generic` macro plays a key role in reducing direct need of the user to wrangle with mangled definition identifiers of 'templated' containers or for type coercion to map distinct data types to a common code path.
+
+Because of its lack of use in many C11 libraries.. and, of those that do; they usually end up obfuscating it with excessive preprocessor abuse; Effort was put into minimizing how much of these macros are handled by the preprocessor vs gencpp itself.
+
+The usual presentation (done bare) is the following:
+
+```c
+#define macro_that_selects_typeof_arg(arg, y) \
+_Generic( (arg),                              \
+    int            : some expression,         \
+    double         : some other expression,   \
+    struct Whatnot : something else again,    \
+    default        : fallback expression      \
+)
+```
+
+Where `_Generic` can be considered the follwoing (psuedo-C):
+
+```c
+#define type_expr_pair(type, expr) type: expr
+
+C_Expression _Generic( selector_arg, a_type_expr_pair, ... ) {
+    switch( typeof(selector_arg)) {
+        case a_type_expr_pair:
+            return a_type_expr_pari.expr;
+        ...
+        default:
+            return default.expr;
+    }
+}
+```
+
+The first `arg` of _Generic behaves as the "controlling expression" or the expression that resolves to a type which will dictate which of the following expressions provided after to `_Generic` will be resolved as the one used inline for the implemenation.
+
+
+For this library's purposes we'll be using the functional macro equivalent *(if there is an exception I'll link it at the end of this section)*:
+
+```c
+#define macro_that_uses_selector_arg_for_resolving_a_fucntion( selecting_exp) \
+_Generic( (arg),                                                              \
+    int            : func_use_int,                                            \
+    double         : func_use_double,                                         \
+    struct Whatnot : func_use_Whatnot,                                        \
+    default        : struct SIGNALS_FAILURE                                   \
+) (selecting_exp)
+```
+
+In this case, we directly added `(selecting_exp)` to the end there.. as we want to directly have the macro resolve to calling a resolved procedure. A default has been set to a struct as that leads to a neat compiler message that would otherwise be impossible beause static_assert is a statement and thus cannot be used within a slot.
+
+Now, even with gencpp generating this type-expression table, we still need wrapper macros to achieve function 'overloading' for the templated containers as _Generic has a [significant drawback](https://www.chiark.greenend.org.uk/~sgtatham/quasiblog/c11-generic/):  
+
+> Discarded expressions still have to be semantically valid.
+
+The only way to absolve this issue [(without resorting to nasty preprocessor hacks)](https://github.com/JacksonAllan/CC/blob/main/articles/Better_C_Generics_Part_1_The_Extendible_Generic.md) is with wrapping expressions in 'slot' resolving macros that do not expand if the slot is not defined:
+
+```c
+GEN_IF_MACRO_DEFINED_INCLUDE_THIS_SLOT( GENERIC_SLOT_1__function_sig )
+```
+
+`GENERIC_SLOT_1__function_sig` is our warpper of a "`int, func_use_int`" pair. The `GEN_IF_MACRO_DEFINED_INCLUDE_THIS_SLOT` is a verbse named macro to indicate that that pair will be expanded ***ONLY IF*** its defined.
+
+So for any given templated container interface. Expect the follwoing (taken straight from generation, and just cleaned up formatting):
+
+```c
+#define gen_array_append( selector_arg, ... ) _Generic(                         \
+(selector_arg ),                                                                \
+    GEN_IF_MACRO_DEFINED_INCLUDE_THIS_SLOT( GEN_GENERIC_SLOT_1__array_append )  \
+    GEN_IF_MACRO_DEFINED_INCLUDE_THIS_SLOT( GEN_GENERIC_SLOT_2__array_append )  \
+    GEN_IF_MACRO_DEFINED_INCLUDE_THIS_SLOT( GEN_GENERIC_SLOT_3__array_append )  \
+    GEN_IF_MACRO_DEFINED_INCLUDE_THIS_SLOT( GEN_GENERIC_SLOT_4__array_append )  \

+    GEN_IF_MACRO_DEFINED_INCLUDE_THIS_SLOT( GEN_GENERIC_SLOT_10__array_append ) \
+    default: gen_generic_selection_fail                                         \
+) GEN_RESOLVED_FUNCTION_CALL( &selector_arg, __VA_ARGS__ )
+
+```
+
+*Note(Ed): Unfortunately I cannot get clang-format to output these macros sanely like the above..*  
+*Eventually I'll add some basic builtin formatting but if the user has suggestions for something better I'm open ears...*
+
+`GEN_RESOLVED_FUNCTION_CALL` is an empty define, its just to indicate that its intended to expand to a function call.

+For the most part this follows the same conventions as `gen_segmented`.
+
+This generator uses a separate enumeration definitions for the following:
+
+* [AttributeTokens.csv](./enums/AttributeTokens.csv) : Add your own <MODULE>_API attributes, etc here that are encountered within the Engine.
+* [ESpecifier.csv](./enums/ESpecifier.csv) : Adds the `FORCEINLINE` & `FORCEINLINE_DEBUGGABLE` specfiers (additions are made as they are encountered)
+* [ETokType.csv](./enums/ETokType.csv) : Same modifications as ESpecifier.csv.
+
+A separate [parser_case_macros.cpp](./components/parser_case_macros.cpp) is used to accomodate for the new forceinline specifiers.
+
+The `global` macro the library uses is redefined as an empty substiution.
+
+
+The expected usage of this library is to put into into a third-party plugin module to then use either in editor modules or in shell script done in some stage of hot-reloading or building the Unreal Engine or Project.
