+### 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)
+
+If the specifier is a new trailing specifier on function definitions:
+
+Head into [base_codegen.hpp](./helpers/base_codegen.hpp): `gen_especifier`. There will be an `is_trailing` function that needs to be adjusted with an additional case for the user's new trailing specifier.
+
+### 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
+    * [ast.hpp](./components/ast.hpp): Initial forwards and user defined conversion for Code.
+    * [ast_types.hpp](./components/ast_types.hpp): Define the `AST_<Name>` struct.
+    * [code_types.hpp](./components/code_types.hpp): Defne the `CodeType` struct. If its needs an iterator see: `struct CodeBody` & `struct CodeParams`.
+3. [ast_case_macros.cpp](./components/ast_case_macros.cpp): Review cases here if the new code type needs to be considered.
+4. [ast.cpp](./components/ast.cpp): Need to review
+    * `code_debug_str`
+    * `code_is_equal`
+    * `code_to_strbuilder_ptr`
+    * `code_validate_body`
+5. [code_serialization.cpp](./components/code_serialization.cpp): Define serialization here.
+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.
+9. [interface.parsing.cpp](./components/interface.parsing.cpp): Define the parsing interface implementation.
+10. [lexer.cpp](./components/lexer.cpp): Adjust the lexer as needed.
+11. [parser.cpp](./components/parser.cpp): Adjust the parser as needed.
 
 ## A note on compilation and runtime generation speed
 
-The library is designed to be fast to compile and generate code at runtime as fast as resonable possible on a debug build.
+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.

 ## `parse_global_nspace_constructor_destructor`
 
-1. Look ahead for the start of the arguments for a possible constructor/destructor
-2. Go back past the identifier
-3. Check to see if its a destructor by checking for the `~`
-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          :: ~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 lexing and parsing takes shortcuts from whats expected in the standard.
+## 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>`
+* `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"
+    , name.Text
+);
+```
+
+Macros are tracked using a `MacroTable Macros;` defined as a member of the library's `Context`.
+
+```c
+typedef HashTable(Macro) MacroTable;
+```
+

+
+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.

+* `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:

+* [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.
