+### 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)

+
+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.

+
+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.

+
 Below is an outline of the general alogirithim used for these internal procedures. The intention is to provide a basic briefing to aid the user in traversing the actual code definitions. These appear in the same order as they are in the `parser.cpp` file
 
 ***NOTE: This is still heavily in an alpha state. A large swaph of this can change, make sure these docs are up to date before considering them 1:1 with the repo commit your considering.***
 
 ## `parse_array_decl`

-4. Continue the next token should be a `::`
-5. Determine if the next valid identifier (ignoring possible template parameters) is the same as the first identifier of the function.
-6. If it is we have either a constructor or destructor so parse using their respective functions (`parse_constructor`, `parse_destructor`).
+1. Forward Token Analysis
+   1. Scan for parameter list opening parenthesis
+   2. Template Expression Handling
+      * Track template nesting depth
+      * Account for nested parentheses within templates
+      * Skip until template closure or parameter start
+
+```cpp
+      // Valid patterns:
+      ClassName          ::  ClassName(...)

+      ClassName< T ... > ::  ClassName(...)
+```
+
+2. Constructor/Destructor Identification
+   1. Token Validation Sequence
+      * Verify identifier preceding parameters
+      * Check for destructor indicator (`~`)
+      * Validate scope resolution operator (`::`)
+   2. Left-side Token Analysis
+      * Process nested template expressions
+      * Maintain template/capture level tracking
+      * Locate matching identifier token
+3. Parser Resolution
+   1. Name Pattern Validation
+      * Compare identifier tokens for exact match
+   2. Specialized Parsing
+      * Route to `parser_parse_destructor` for '~' prefix
+      * Route to `parser_parse_constructor` for direct match
+   3. Apply specifiers to resulting node
+4. Return result (`NullCode` on pattern mismatch)
+
+### Implementation Constraints
+
+* Cannot definitively distinguish nested namespaces with identical names
+* Return type detection requires parser enhancement
+* Template parameter validation is syntax-based only
+* Future enhancement: Implement type parsing with rollback capability
 
 ## `parse_identifier`
 
 This is going to get heavily changed down the line to have a more broken down "identifier expression" so that the qualifier, template args, etc, can be distinguished between the targeted identifier.  
 The function can parse all of them, however the AST node compresses them all into a string.
 
-1. Consume first identifier
-2. `parse_template_args`
-3. While there is a static symbol accessor ( `::` )
-    1. Consume `::`
-    2. Consume member identifier
-    3. `parse_template args` (for member identifier)
-    4. If a `~` is encounted and the scope is for a destructor's identifier, do not consume it and return with what parsed.
+1. Initialize identifier context
+   1. Push parser scope
+   2. Capture initial token as name
+   3. Set scope name from token text
+2. Process initial identifier component
+   1. Consume identifier token
+   2. Parse template arguments if present
+3. Handle qualified identifiers (loop while `::` found)
+   1. Consume static access operator
+   2. Validate token sequence:
+       1. Handle destructor operator (`~`)
+           * Validate destructor parsing context
+           * Update name span if valid
+           * Return invalid on context mismatch
+       2. Process member function pointer (`*`)
+           * Set possible_member_function flag if context allows
+           * Return invalid if pointer unexpected
+       3. Verify identifier token follows
+   3. Update identifier span
+       1. Extend name length to include new qualifier
+       2. Consume identifier token
+       3. Parse additional template arguments
+4. Return completed identifier token
+
+Technical notes:
+
+* Current implementation treats identifier as single token span
+* TODO: Refactor to AST-based identifier representation for:
+  * Distinct qualifier/symbol tracking
+  * Improved semantic analysis capabilities
+  * Better support for nested symbol resolution

+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>`
+* `MF_Allow_As_Identifier`: Will allow the macro to be an acceptable token/s when an `Tok_Identifier` is expected.
+* `MF_Allow_As_Attribute`: Will allow the macro to be an acceptable token/s when an attribute token/s is expected.
+* `MF_Allow_As_Definition`: Will allow the macro be an acceptable token/s when the parser expects a declartion or definition to resolve after attributes or specifiers have been identified beforehand.
+  * This flag requires that the macro is of type `MT_Statement` to make any sense of usage.
+
+If a macro is not defined the following warning will be issued if `GEN_BUILD_DEBUG=1` during lexing within [lexer.cpp](../base/components/lexer.cpp) - `lex_preprocessor_define`:
+
+```c
+log_fmt("Warning: '%S' was not registered before the lexer processed its #define directive, it will be registered as a expression macro\n"
+    , name.Text 
+);
+```
+
+Further within the same scope, the lexer will issue a warning if it detects a macro was not flagged as function but has an open parenthesis `(` token right after is name with no whitespace:
+
+```c
+log_fmt("Warning: %S registered macro is not flagged as functional yet the definition detects opening parenthesis '(' for arguments\n"

+
+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 );

 **If c_library.refactor is modified you may need to modify c_library.cpp and its [components](./components/). As some of the container generation relies on that prefix.**

+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 )  \

+    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.

+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.
