Comment, Constructor, Destructor, Define, Enum, Exec, Extern, Include, Friend, Fn codes member proc usage reductions

Most likely will just reduce them to C-enums with underlying type.
Otherwise there has to be a mechanism to drop the defs down to them anyways, and eliminate the namespace wraps.

 ## Building
 
-An example of building is provided in the test directory.
-
-There are two meson build files the one within test is the program's build specification.  
-The other one in the gen directory within test is the metaprogram's build specification.
-
-Both of them build the same source file: `test.cpp`. The only differences are that gen needs a different relative path to the include directories and defines the macro definition: `gen_time`.
-
-This method is setup where all the metaprogram's code are the within the same files as the regular program's code.  
-
-## Outline
-
-### *WHAT IS NOT PROVIDED*
-
-* Lambdas
-* Lang provided dynamic dispatch (virtuals) : `override` and `final` specifiers complicate the specifier parsing and serialization. (Its a todo)
-* Suffix specifiers for functions (Ex: void() const ). Same reason as virtual/override/final missing for now.
-* RTTI
-* Exceptions
-* Execution statement validation              : Execution expressions are defined using the untyped API.
-* Parsing support for module specifiers and attributes. (Its a todo)
-
-Keywords kept from "Modern C++":
-
-* constexpr : Great to store compile-time constants.
-* consteval : Technically fine, need to make sure to execute in moderation.
-* 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    : ^^
-
-When it comes to expressions:
-
-**There is no support for validating expressions.**  
-**The reason:** Its difficult to parse without enough benefits.  
-Most of the time, the critical complex metaprogramming conundrums are producing the frame of abstractions around the expressions (which this library provides constructors to help validate, you can skip that process by using the untyped constructors).  
-Its not a priority to add such a level of complexity to the library when there isn't a high reward or need for it.  
-Especially when the priority is to keep this library small and easy to grasp for what it is.
-
-When it comes to templates:
-
-Only trivial template support is provided. the intention is for only simple, non-recursive subsitution.  
-The parameters of the template are treated like regular parameter AST entries.  
-This means that the typename entry for the parameter AST would be either:
-
-* `class`
-* `typename`
-* A fundamental type, function, or pointer type.
-
-Anything beyond this usage is not supported by parse_template for arguments (at least not intentionally).  
-Use at your own mental peril...
-
-*Concepts and Constraints are not supported, its usage is non-tirival substiution.*
-
-### The Data & Interface
-
-As mentioned in [Usage](#usage), the user is provided Code objects by calling the constructor's functions to generate them or find existing matches.
-
-The AST is managed by the library and provided the user via its interface.  
-However, the user may specifiy memory configuration.
-
-Data layout of AST struct:
-
-```cpp
-union {
-    struct
-    {
-        AST*      Attributes;     // Class, Enum, Function, Struct, Typedef, Union, Using, Variable
-        AST*      Specs;          // Function, Operator, Type symbol, Variable
-        union {
-            AST*  ParentType;     // Class, Struct
-            AST*  ReturnType;     // Function, Operator
-            AST*  UnderlyingType; // Enum, Typedef
-            AST*  ValueType;      // Parameter, Variable
-        };
-        AST*      Params;         // Function, Operator, Template
-        union {
-            AST*  ArrExpr;        // Type Symbol
-            AST*  Body;           // Class, Enum, Function, Namespace, Struct, Union
-            AST*  Declaration;    // Friend, Template
-            AST*  Value;          // Parameter, Variable
-        };
-    };
-    StringCached  Content;        // Attributes, Comment, Execution, Include
-    SpecifierT    ArrSpecs[AST::ArrSpecs_Cap]; // Specifiers
-};
-union {
-    AST* Prev;
-    AST* Front; // Used by CodeBody
-    AST* Last;  // Used by CodeParam
-};
-union {
-    AST* Next;
-    AST* Back;  // Used by CodeBody
-};
-AST*              Parent;
-StringCached      Name;
-CodeT             Type;
-ModuleFlag        ModuleFlags;
-union {
-    OperatorT     Op;
-    AccessSpec    ParentAccess;
-    s32           NumEntries;
-};
-```
-
-*`CodeT` is a typedef for `ECode::Type` which has an underlying type of `u32`*  
-*`OperatorT` is a typedef for `EOperator::Type` which has an underlying type of `u32`*  
-*`StringCahced` is a typedef for `String const`, to denote it is an interned string*  
-*`String` is the dynamically allocated string type for the library*
-
-AST widths are setup to be AST_POD_Size.
-The width dictates how much the static array can hold before it must give way to using an allocated array:
-
-```cpp
-constexpr static
-uw ArrSpecs_Cap =
-(
-        AST_POD_Size
-        - sizeof(AST*) * 3
-        - sizeof(StringCached)
-        - sizeof(CodeT)
-        - sizeof(ModuleFlag)
-        - sizeof(s32)
-)
-/ sizeof(SpecifierT) -1; // -1 for 4 extra bytes (Odd num of AST*)
-```
-
-*Ex: If the AST_POD_Size is 128 the capacity of the static array is 20.*
-
-Data Notes:
-
-* The allocator definitions used are exposed to the user incase they want to dictate memory usage
-  * You'll find the memory handling in `init`, `gen_string_allocator`, `get_cached_string`, `make_code`.
-* ASTs are wrapped for the user in a Code struct which is a warpper for a AST* type.
-* Both AST and Code have member symbols but their data layout is enforced to be POD types.
-* This library treats memory failures as fatal.
-* Strings are stored in their own set of arenas. AST constructors use cached strings for names, and content.
-  * `StringArenas`, `StringCache`, `Allocator_StringArena`, and `Allocator_StringTable` are the associated containers or allocators.
-* Strings used for seralization and file buffers are not contained by those used for cached strings.
-  * They are currently using `Memory::GlobalAllocator`, which are tracked array of arenas that grows as needed (adds buckets when one runs out).
-  * Memory within the buckets is not resused, so its inherently wasteful (most likely will give non-cached strings their own tailored allocator later)
-* Linked lists used children nodes on bodies, and parameters.
-* Its intended to generate the AST in one go and serialize after. The contructors and serializer are designed to be a "one pass, front to back" setup.
-* When benchmarking, the three most significant var to tune are:
-  * `Memory::Global_BlockSize` (found gen_dep.hpp) : Used by the GlobalAllocator for the size of each global arena.
-  * `SizePer_StringArena` (found in gen.hpp under the constants region) : Used by the string cache to store strings.
-  * `CodePool_NumBlocks` (found in gen.hpp under constants region) : Used by code pool to store ASTs.
-  * The default values can handled generating for a stirng up to a size of ~650 kbs (bottleneck is serialization).
-  * Increasing the values can generate files upwards of over a million lines without issue (the formatter will most likely run slower than it)
-
-Two generic templated containers are used throughout the library:
-
-* `template< class Type> struct Array`
-* `template< class Type> struct HashTable`
-
-Both Code and AST definitions have a `template< class Type> Code/AST cast()`. Its just an alternative way to explictly cast to each other.
-
-Otherwise the library is free of any templates.
-
-The following CodeTypes are used which the user may optionally use strong typeing with if they enable: `GEN_ENFORCE_STRONG_CODE_TYPES`
-
-* CodeBody : Has support for `for-range` iterating across Code objects.
-* CodeAttributes
-* CodeComment
-* CodeClass
-* CodeEnum
-* CodeExec
-* CodeExtern
-* CodeInclude
-* CodeFriend
-* CodeFn
-* CodeModule
-* CodeNamespace
-* CodeOperator
-* CodeOpCast
-* CodeParam : Has suppor for `for-range` iterating across parameters.
-* CodeSpecifier : Has support for `for-range` iterating across specifiers.
-* CodeStruct
-* CodeTemplate
-* CodeType
-* CodeTypedef
-* CodeUnion
-* CodeUsing
-* CodeUsingNamespace
-* CodeVar
-
-Each Code boy has an assoicated "filtered AST" with the naming convention: `AST_<CodeName>`
-Unrelated fields of the AST for that node type are omitted and only necesary padding members are defined otherwise.
-Retreiving a raw version of the ast can be done using the `raw()` function defined in each AST.
-
-## There are three sets of interfaces for Code AST generation the library provides
-
-* Upfront
-* Parsing
-* Untyped

-All component ASTs must be previously constructed, and provided on creation of the code AST.
-The construction will fail and return Code::Invalid otherwise.
-
-Interface :``
-
-* def_attributes
-  * *This is preappened right before the function symbol, or placed after the class or struct keyword for any flavor of attributes used.*
-  * *Its up to the user to use the desired attribute formatting: `[[]]` (standard), `__declspec` (Microsoft), or `__attribute__` (GNU).*
-* def_comment
-* def_class
-* def_enum
-* def_execution
-  * *This is equivalent to untyped_str, except that its intended for use only in execution scopes.*
-* def_extern_link
-* def_friend
-* def_function
-* def_include
-* def_module
-* def_namespace
-* def_operator
-* def_operator_cast
-* def_param
-* def_params
-* def_specifier
-* def_specifiers
-* def_struct
-* def_template
-* def_type
-* def_typedef
-* def_union
-* def_using
-* def_using_namespace
-* def_variable
-
-Bodies:
-
-* def_body
-* def_class_body
-* def_enum_body
-* def_export_body
-* def_extern_link_body
-* def_function_body
-  * *Use this for operator bodies as well*
-* def_global_body
-* def_namespace_body
-* def_struct_body
-* def_union_body
-
-Usage:
-
-```cpp
-<name> = def_<function type>( ... );
-
-Code <name>
-{
-    ...
-    <name> = def_<function name>( ... );
-}
-
-```
-
-When using the body functions, its recommended to use the args macro to auto determine the number of arguments for the varadic:
-```cpp
-def_global_body( args( ht_entry, array_ht_entry, hashtable ));
-
-// instead of:
-def_global_body( 3, ht_entry, array_ht_entry, hashtable );
-```
-
-If a more incremental approach is desired for the body ASTs, `Code def_body( CodeT type )` can be used to create an empty body.  
-When the members have been populated use: `AST::validate_body` to verify that the members are valid entires for that type.
-
-### Parse construction
-
-A string provided to the API is parsed for the intended language construct.
-
-Interface :
-
-* parse_class
-* parse_enum
-* parse_export_body
-* parse_extern_link
-* parse_friend
-  * Purposefully are only support forward declares with this constructor.
-* parse_function
-* parse_global_body
-* parse_namespace
-* parse_operator
-* parse_operator_cast
-* parse_struct
-* parse_template
-* parse_type
-* parse_typedef
-* parse_union
-* parse_using
-* parse_variable
-
-The lexing and parsing takes shortcuts from whats expected in the standard.
-
-* Numeric literals are not check for validity.
-* The parse API treats any execution scope definitions with no validation and are turned into untyped Code ASTs.
-  * *This includes the assignment of variables.*
-* Attributes ( `[[]]` (standard), `__declspec` (Microsoft), or `__attribute__` (GNU) )
-  * Assumed to *come before specifiers* (`const`, `constexpr`, `extern`, `static`, etc) for a function
-  * Or in the usual spot for class, structs, (*right after the declaration keyword*)
-  * typedefs have attributes with the type (`parse_type`)
-* As a general rule; if its not available from the upfront contructors, its not available in the parsing constructors.
-  * *Upfront constructors are not necessarily used in the parsing constructors, this is just a good metric to know what can be parsed.*
-
-Usage:
-
-```cpp
-Code <name> = parse_<function name>( string with code );
-
-Code <name> = def_<function name>( ..., parse_<function name>(
-    <string with code>
-));
-
-Code <name> = make_<function name>( ... )
-{
-    <name>->add( parse_<function name>(
-        <string with code>
-    ));
-}
-```
-
-### Untyped constructions
-
-Code ASTs are constructed using unvalidated strings.
-
-Interface :
-
-* token_fmt_va
-* token_fmt
-* untyped_str
-* untyped_fmt
-* untyped_token_fmt
-
-During serialization any untyped Code AST has its string value directly injected inline of whatever context the content existed as an entry within.  
-Even though these are not validated from somewhat correct c/c++ syntax or components, it doesn't mean that Untyped code can be added as any component of a Code AST:
-
-* Untyped code cannot have children, thus there cannot be recursive injection this way.
-* Untyped code can only be a child of a parent of body AST, or for values of an assignment (ex: variable assignment).
-
-These restrictions help prevent abuse of untyped code to some extent.
-
-Usage Conventions:
-
-```cpp
-Code <name> = def_varaible( <type>, <name>, untyped_<function name>(
-    <string with code>
-));
-```
-
-Template metaprogramming in the traditional sense becomes possible with the use of `token_fmt` and parse constructors:
-
-```cpp
-StrC value = txt_StrC("Something");
-
-char const* template_str = txt(
-    Code with <key> to replace with token_values
-    ...
-);
-char const* gen_code_str = token_fmt( "key", value, template_str );
-Code        <name>       = parse_<function name>( gen_code_str );
-```
-
-## Predefined Codes
-
-The following are provided predefined by the library as they are commonly used:
-
-* `access_public`
-* `access_protected`
-* `access_private`
-* `module_global_fragment`
-* `module_private_fragment`
-* `pragma_once`
-* `spec_const`
-* `spec_consteval`
-* `spec_constexpr`
-* `spec_constinit`
-* `spec_extern_linkage` (extern)
-* `spec_global` (global macro)
-* `spec_inline`
-* `spec_internal_linkage` (internal macro)
-* `spec_local_persist` (local_persist macro)
-* `spec_mutable`
-* `spec_ptr`
-* `spec_ref`
-* `spec_register`
-* `spec_rvalue`
-* `spec_static_member` (static)
-* `spec_thread_local`
-* `spec_volatile`
-* `spec_type_signed`
-* `spec_type_unsigned`
-* `spec_type_short`
-* `spec_type_long`
-* `t_auto`
-* `t_void`
-* `t_int`
-* `t_bool`
-* `t_char`
-* `t_wchar_t`
-* `t_class`
-* `t_typename`
-
-Optionally the following may be defined if `GEN_DEFINE_LIBRARY_CODE_CONSTANTS` is defined
-
-* `t_b32`
-* `t_s8`
-* `t_s16`
-* `t_s32`
-* `t_s64`
-* `t_u8`
-* `t_u16`
-* `t_u32`
-* `t_u64`
-* `t_sw`
-* `t_uw`
-* `t_f32`
-* `t_f64`
-
-## Extent of operator overload validation
-
-The AST and constructors will be able to validate that the arguments provided for the operator type match the expected form:
-
-* If return type must match a parameter
-* If number of parameters is correct
-* If added as a member symbol to a class or struct, that operator matches the requirements for the class (types match up)
-
-The user is responsible for making sure the code types provided are correct
-and have the desired specifiers assigned to them beforehand.
-
-## Code generation and modification
-
-There are three provided file interfaces:
-
-* Builder
-* Editor
-* Scanner
-
-Editor and Scanner are disabled by default, use `GEN_FEATURE_EDITOR` and `GEN_FEATURE_SCANNER` to enable them.
-
-### Builder is a similar object to the jai language's string_builder
-
-* The purpose of it is to generate a file.
-* A file is specified and opened for writting using the open( file_path) ) function.
-* The code is provided via print( code ) function  will be seralized to its buffer.
-* When all seralization is finished, use the write() command to write the buffer to the file.
-
-### Editor is for editing a series of files based on a set of requests provided to it
-
-**Note: Not implemented yet**
-
-* The purpose is to overrite a specific file, it places its contents in a buffer to scan.
-* Requests are populated using the following interface:
-  * add : Add code.
-  * remove : Remove code.
-  * replace: Replace code.
-
-All three have the same parameters with exception to remove which only has SymbolInfo and Policy:
-
-* SymbolInfo:
-  * File      : The file the symbol resides in. Leave null to indicate to search all files. Leave null to indicated all-file search.
-  * Marker    : #define symbol that indicates a location or following signature is valid to manipulate. Leave null to indicate the signature should only be used.
-  * Signature : Use a Code symbol to find a valid location to manipulate, can be further filtered with the marker. Leave null to indicate the marker should only be used.
-
-* Policy : Additional policy info for completing the request (empty for now)
-* Code   : Code to inject if adding, or replace existing code with.
-
-Additionally if `GEN_FEATURE_EDITOR_REFACTOR` is defined, refactor( file_path, specification_path ) wil be made available.  
-Refactor is based of the refactor library and uses its interface.  
-It will on call add a request to the queue to run the refactor script on the file.
-
-### Scanner allows the user to generate Code ASTs by reading files
-
-**Note: Not implemented yet**
-
-* The purpose is to grab definitions to generate metadata or generate new code from these definitions.
-* Requests are populated using the add( SymbolInfo, Policy ) function. The symbol info is the same as the one used for the editor. So is the case with Policy.
-
-The file will only be read from, no writting supported.
-
-One great use case is for example: generating the single-header library for gencpp!
-
-### Additional Info (Editor and Scanner)
-
-When all requests have been populated, call process_requests().  
-It will provide an output of receipt data of the results when it completes.
-
-Files may be added to the Editor and Scanner additionally with add_files( num, files ).  
-This is intended for when you have requests that are for multiple files.
-
-Request queue in both Editor and Scanner are cleared once process_requests completes.
-
-## On multi-threading
-
-Currently unsupported. The following changes would have to be made:
-
-* Setup static data accesss with fences if more than one thread will generate ASTs ( or keep a different set for each thread)
-* Make sure local peristent data of functions are also thread local.
-* The builder should be done on a per-thread basis.
-* Due to the design of the editor and scanner, it will most likely be best to make each file a job to process request entries on. Receipts should have an an array to store per thread. They can be combined to the final reciepts array when all files have been processed.
-
-## Extending the library
-
-This library is relatively very small, and can be extended without much hassle.
-
-The untyped codes and builder/editor/scanner can be technically be used to circumvent
-any sort of constrictions the library has with: modern c++, templates, macros, etc.
-
-Typical use case is for getting define constants an old C/C++ library with the scanner:  
-Code parse_defines() can emit a custom code AST with Macro_Constant type.
-
-Another would be getting preprocessor or template metaprogramming Codes from Unreal Engine definitions, etc.
-
-The rules for constructing the AST are largely bound the syntax rules for what can be composed with whichever version of C++ your targeting.
-
-The convention you'll see used throughout the API 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 seralization 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 sophisitacated constructor as it has multiple permutations of definitions that could be created that are not trivial to determine if valid.
-
-# TODO
-
-* Implement a context stack for the parsing, allows for accurate scope validation for the AST types.
-* Make a more robust test suite.
-* Generate a single-header library.
-* Improve the allocation strategy for strings in `Builder`, `AST::to_string`, `Parser::lex`, all three can use some form of slab allocation strategy...
-  * Can most likely use a simple slag allocator.
-* May be in need of a better name, I found a few repos with this same one...
-* Support module and attribute parsing (Marked with TODOs for now..)
-* Suffix specifiers for functions (const, override, final)
-* Implement the Scanner
-* Implement the Editor

+## Current Design
+
+`AST` is the actual managed node object for the library.  
+Its raw and really not meant to be used directly.
+
+All user interaction must be with its pointer so the type they deal with is `AST*`.  
+For user-facing code, they should never be giveen a nullptr. Instead, they should be given a designated `Invalid` AST node.
+
+In order to abstract away constant use of `AST*`, I wanted to provide a wrapper for it.
+
+The simpliest being just a type alias.
+
+```cpp
+using Code = AST*;
+```
+
+This is what the genc library would have to use due to its constraints of a langauge.  
+The actual content per type of AST is covered within [AST_Types.md](AST_Types.md).
+
+These are pure PODS that just have the lay members relevant to the type of AST node they represent.  
+Each of them has a Code type alias specific to it.
+
+Again, the simpliest case for these would be a type alias.
+
+```cpp
+using struct AST_Typedef CodeTypedef;
+```
+
+As of November 21st, 2023, the AST has had a strict layout for how its content is laid out.  
+This will be abandoned during its redesign that will occur starting with support for statments & expressions for either execution and type declarations.  
+Having a strict layout is too resctrictive vs allowing each AST type to have maximum control over the layout.
+
+The redesign will occur after the following todos are addressed:
+
+* [Improvements Lexer & Token struct#27](https://github.com/Ed94/gencpp/issues/27)
+* [Generalize AST Flags to a single 4-byte flag#42](https://github.com/Ed94/gencpp/issues/42)

+
+While the Readme for docs covers the data layout per AST, this will focus on the AST types avaialble, and their nuances.
+
+## Body
+
+These are containers representing a scope body of a definition that can be of the following `ECode` type:
+
+* Class_Body
+* Enum_Body
+* Export_Body
+* Extern_Linkage_Body
+* Function_Body
+* Global_Body
+* Namespace_Body
+* Struct_Body
+* Union_Body
+
+Fields:
+
+```cpp
+Code           Front;
+Code           Back;
+parser::Token* Tok;
+Code           Parent;
+StringCached   Name;
+CodeT          Type;
+s32            NumEntries;
+```
+
+The `Front` member represents the start of the link list and `Back` the end.
+NumEntries is the number of entries in the body.
+
+Parent should have a compatible ECode type for the type of defintion used.
+
+Serialization:
+
+Will output only the entries, the braces are handled by the parent.
+
+```cpp
+<Front>...
+<Back>
+```
+
+## Attributes
+
+Represent standard or vendor specific C/C++ attributes.
+
+Fields:
+
+```cpp
+StringCached   Content;
+Code           Prev;
+Code           Next;
+parser::Token* Tok;
+Code           Parent;
+StringCached   Name;
+CodeT          Type;
+```
+
+Serialization:
+
+```cpp
+<Content>
+```
+
+While the parser supports the `__declspec` and `__attribute__` syntax, the upfront constructor ( def_attributes ) must have the user specify the entire attribute, including the `[[]]`, `__declspec` or `__attribute__` parts.
+
+## Comment
+
+Stores a comment.
+
+Fields:
+
+```cpp
+StringCached   Content;
+Code           Prev;
+Code           Next;
+parser::Token* Tok;
+Code           Parent;
+StringCached   Name;
+CodeT          Type;
+```
+
+Serialization:
+
+```cpp
+<Content>
+```
+
+The parser will perserve comments found if residing with a body or in accepted inline-to-definition locations.
+Otherwise they will be skipped by the TokArray::__eat and TokArray::current( skip foramtting enabled ) functions.
+
+The upfront constructor: `def_comment` expects to recieve a comment without the `//` or `/* */` parts. It will add them during construction.
+
+## Class & Struct
+
+Fields:
+
+```cpp
+CodeComment    InlineCmt;  // Only supported by forward declarations
+CodeAttributes Attributes;
+CodeType       ParentType;
+CodeBody       Body;
+CodeType       Prev;       // Used to store references to interfaces
+CodeType       Next;       // Used to store references to interfaces
+parser::Token* Tok;
+Code           Parent;
+StringCached   Name;
+CodeT          Type;
+ModuleFlag     ModuleFlags;
+AccessSpec     ParentAccess;
+```
+
+Serialization:
+
+```cpp
+// Class_Fwd
+<ModuleFlags> <class/struct> <Name>; <InlineCmt>
+
+// Class
+<ModuleFlags> <class/struct> <Attributes> <Name> : <ParentAccess> <ParentType>, public <ParentType->Next>, ... <InlineCmt>
+{
+    <Body>
+};
+```
+
+You'll notice that only one parent type is supported only with parent access. This library only supports single inheritance, the rest must be done through interfaces.

+# Parser's Algorithim
+
+gencpp uses a hand-written recursive descent parser. Both the lexer and parser currently handle a full C/C++ file in a single pass.
+
+## Notable implementation background
+
+### Lexer
+
+The lex procedure does the lexical pass of content provided as a `StrC` type.
+The tokens are stored (for now) in `gen::parser::Tokens`.
+
+Fields:
+
+```cpp
+Array<Token> Arr;
+s32          Idx;
+```
+
+What token types are supported can be found in [ETokType.csv](../project/enums/ETokType.csv) you can also find the token types in [ETokType.h](../project/components/gen/etoktype.cpp) , which is the generated enum from the csv file.
+
+Tokens are defined with the struct `gen::parser::Token`:
+
+Fields:
+
+```cpp
+char const* Text;
+sptr        Length;
+TokType     Type;
+s32         Line;
+s32         Column;
+u32         Flags;
+```
+
+Flags is a bitfield made up of TokFlags (Token Flags):
+
+* `TF_Operator` : Any operator token used in expressions
+* `TF_Assign`
+  * Using statment assignment
+  * Parameter argument default value assignment
+  * Variable declaration initialization assignment
+* `TF_Preprocess` : Related to a preprocessing directive
+* `TF_Preprocess_Cond` : A preprocess conditional
+* `TF_Attribute` : An attribute token
+* `TF_AccessSpecifier` : An accesor operation token
+* `TF_Specifier` : One of the specifier tokens
+* `TF_EndDefinition` : Can be interpreted as an end definition for a scope.
+* `TF_Formatting` : Considered a part of the formatting
+* `TF_Literal` : Anything considered a literal by C++.
+
+I plan to replace IsAssign with a general flags field and properly keep track of all operator types instead of abstracting it away to `ETokType::Operator`.
+
+Traversing the tokens is done with the following interface macros:
+
+| Macro | Description |
+| --- | --- |
+| `currtok_noskip` | Get the current token without skipping whitespace |
+| `currtok` | Get the current token, skip any whitespace tokens |
+| `prevtok` | Get the previous token (does not skip whitespace) |
+| `nexttok` | Get the next token (does not skip whitespace) |
+| `eat( Token Type )` | Check to see if the current token is of the given type, if so, advance Token's index to the next token |
+| `left` | Get the number of tokens left in the token array |
+| `check_noskip` | Check to see if the current token is of the given type, without skipping whitespace |
+| `check` | Check to see if the current token is of the given type, skip any whitespace tokens |
+
+### Parser
+
+The parser has a limited user interface, only specific types of definitions or statements are expected to be provided by the user directly when using to construct an AST dynamically (See SOA for example). It however does attempt to provide capability to parse a full C/C++ from production codebases.
+
+Each public user interface procedure has the following format:
+
+```cpp
+<code type> parse_<definition type>( StrC def )
+{
+    check_parse_args( def );
+    using namespace Parser;
+
+    TokArray toks = lex( def );
+    if ( toks.Arr == nullptr )
+        return CodeInvalid;
+
+    // Parse the tokens and return a constructed AST using internal procedures
+    ...
+}
+```
+
+The most top-level parsing procedure used for C/C++ file parsing is `parse_global_body`:
+
+It uses a helper procedure called `parse_global_nspace`.
+
+Each internal procedure will have the following format:
+
+```cpp
+internal
+<code type> parse_<definition_type>( <empty or contextual params> )
+{
+    push_scope();
+
+    ...
+
+    <code type> result = (<code type>) make_code();
+    ...
+
+    Context.pop();
+    return result;
+}
+```
+
+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`
+
+1. Check if its an array declaration with no expression.
+    1. Consume and return empty array declaration
+2. Opening square bracket
+3. Consume expression

+7. If not an inplace definition
+    1. End statement
+    2. Check for inline comment

+## `parse_class_struct_body`
+
+1. Opening curly brace
+2. Parse the body (Possible options):
+    1. Ignore dangling end statements
+    2. Newline : ast constant
+    3. Comment : `parse_comment`
+    4. Access_Public : ast constant
+    5. Access_Protected : ast constant
+    6. Access_Private : ast constant
+    7. Decl_Class : `parse_complicated_definition`
+    8. Decl_Enum : `parse_complicated_definition`
+    9. Decl_Friend : `parse_friend`
+    10. Decl_Operator : `parse_operator_cast`
+    11. Decl_Struct : `parse_complicated_definition`
+    12. Decl_Template : `parse_template`
+    13. Decl_Typedef : `parse_typedef`
+    14. Decl_Union : `parse_complicated_definition`
+    15. Decl_Using : `parse_using`
+    16. Operator == '~'
+        1. `parse_destructor`
+    17. Preprocess_Define : `parse_define`
+    18. Preprocess_Include : `parse_include`
+    19. Preprocess_Conditional (if, ifdef, ifndef, elif, else, endif) : `parse_preprocess_cond` or else/endif ast constant
+    20. Preprocess_Macro : `parse_simple_preprocess`
+    21. Preprocess_Pragma : `parse_pragma`
+    22. Preprocess_Unsupported : `parse_simple_preprocess`
+    23. StaticAssert : `parse_static_assert`
+    24. The following compound into a resolved definition or declaration:
+        1. Attributes (Standard, GNU, MSVC) : `parse_attributes`
+        2. Specifiers (consteval, constexpr, constinit, explicit, forceinline, inline, mutable, neverinline, static, volatile, virtual)
+        3. Possible Destructor : `parse_destructor`
+        4. Possible User defined operator cast : `parse_operator_cast`
+        5. Possible Constructor : `parse_constructor`
+        6. Something that has the following: (identifier, const, unsigned, signed, short, long, bool, char, int, double)
+            1. Possible Constructor `parse_constructor`
+            2. Possible Operator, Function, or varaible : `parse_operator_function_or_variable`
+    25. Something completely unknown (will just make untyped...) : `parse_untyped`
+
+## `parse_comment`
+
+1. Just wrap the token into a cached string ( the lexer did the processing )
+
+## `parse_compilcated_definition`
+
+This is a helper function used by the following functions to help resolve a declaration or definition:
+
+* `parse_class_struct_body`
+* `parse_global_nspace`
+* `parse_union`
+
+A portion of the code in `parse_typedef` is very similar to this as both have to resolve a similar issue.
+
+1. Look ahead to the termination token (End statement)
+2. Check to see if it fits the pattern for a forward declare
+3. If the previous token was an identifier ( `token[-1]` ):
+    1. Look back one more token : `[-2]`
+    2. If the token has a closing brace its an inplace definition
+    3. If the `token[-2]` is an identifier & `token[-3]` is the declaration type, its a variable using a namespaced type.
+    4. If the `token[-2]` is an indirection, then its a variable using a namespaced/forwarded type.
+    5. If the `token[-2]` is an assign classifier, and the starting tokens were the which type with possible `class` token after, its an enum forward declaration.
+    6. If any of the above is the case, `parse_operator_function_or_variable`
+4. If the `token[2]` is a vendor fundamental type (builtin) then it is an enum forward declaration.
+5. If the previous token was a closing curly brace, its a definition : `parse_forward_or_definition`
+6. If the previous token was a closing square brace, its an array definition : `parse_operator_function_or_variable`
+
+## `parse_define`
+
+1. Define directive
+2. Get identifier
+3. Get Content (Optional)
+
+## `parse_forward_or_definition`
+
+* Parse any of the following for either a forward declaration or definition:
+    1. Decl_Class : `parse_class`
+    2. Decl_Enum : `parse_enum`
+    3. Decl_Struct : `parse_struct`
+    4. Decl_Union : `parse_union`
+
+## `parse_function_after_name`
+
+This is needed as a function defintion is not easily resolvable early on, as such this function handles resolving a function
+after its been made ceratin that the type of declaration or definition is indeed for a function signature.
+
+By the point this function is called the following are known : export module flag, attributes, specifiers, return type, & name
+
+1. `parse_parameters`
+2. parse postfix specifiers (we do not check if the specifier here is correct or not to be here... yet)
+3. If there is a body : `parse_body`
+4. Otherwise :
+     1. Statment end
+     2. Check for inline comment
+
+## `parse_function_body`
+
+Currently there is no actual parsing of the function body. Any content with the braces is shoved into an execution AST node.
+In the future statements and expressions will be parsed.
+
+1. Open curly brace
+2. Grab all tokens between the brace and the closing brace, shove them in a execution AST node.
+3. Closing curly brace
+
+## `parse_global_nspace`
+
+1. Make sure this is being called for a valid type (namespace, global body, export body, linkage body)
+2. If its not a global body, consume the opening curly brace
+3. Parse the body (Possible options):
+    1. Ignore dangling end statements
+    2. NewLine : ast constant
+    3. Comment : `parse_comment`
+    4. Decl_Cass : `parse_complicated_definition`
+    5. Decl_Enum : `parse_complicated_definition`
+    6. Decl_Extern_Linkage : `parse_extern_link`
+    7. Decl_Namespace : `parse_namespace`
+    8. Decl_Struct : `parse_complicated_definition`
+    9. Decl_Template : `parse_template`
+    10. Decl_Typedef : `parse_typedef`
+    11. Decl_Union : `parse_complicated_definition`
+    12. Decl_Using : `parse_using`
+    13. Preprocess_Define : `parse_define`
+    14. Preprocess_Include : `parse_include`
+    15. Preprocess_If, IfDef, IfNotDef, Elif : `parse_preprocess_cond`
+    16. Preprocess_Else : ast constant
+    17. Preprocess_Endif : ast constant
+    18. Preprocess_Macro : `parse_simple_preprocess`
+    19. Preprocess_Pragma : `parse_pragma`
+    20. Preprocess_Unsupported : `parse_simple_preprocess`
+    21. StaticAssert : `parse_static_assert`
+    22. Module_Export : `parse_export_body`
+    23. Module_Import : NOT_IMPLEMENTED
+    24. The following compound into a resolved definition or declaration:
+        1. Attributes ( Standard, GNU, MSVC, Macro ) : `parse_attributes`
+        2. Specifiers ( consteval, constexpr, constinit, extern, forceinline, global, inline, internal_linkage, neverinline, static )
+        3. Is either ( identifier, const specifier, long, short, signed, unsigned, bool, char, double, int)
+            1. Attempt to parse as constrcutor or destructor : `parse_global_nspace_constructor_destructor`
+            2. If its an operator cast (definition outside class) : `parse_operator_cast`
+            3. Its an operator, function, or varaible : `parse_operator_function_or_varaible`
+4. If its not a global body, consume the closing curly brace
+
+## `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`).
+
+## `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.
+
+## `parse_include`
+
+1. Consume include directive
+2. Consume the path
+
+## `parse_operator_after_ret_type`
+
+This is needed as a operator defintion is not easily resolvable early on, as such this function handles resolving a operator after its been made ceratin that the type of declaration or definition is indeed for a operator signature.
+
+By the point this function is called the following are known : export module flag, attributes, specifiers, return type
+
+1. If there is any qualifiers for the operator, parse them
+2. Consume operator keyword
+3. Determine the operator type (This will be offloaded to the lexer moreso than how it is now) & consume
+4. `parse_params`
+5. If there is no parameters this is operator is a member of pointer if its symbols is a *.
+6. Parse postfix specifiers
+7. If there is a opening curly brace, `parse function_body`
+8. Otherwise: consume end statement, check for inline comment.
+
+## `parse_operator_function_or_variable`
+
+When this function is called, attribute and specifiers may have been resolved, however what comes next can still be either an operator, function, or varaible.
+
+1. Check for preprocessor macro, if there is one : `parse_simple_preprocess`
+2. `parse_type` (Does the bulk of the work)
+3. Begin lookahead to see if we get qualifiers or we eventually find the operator declaration
+4. If we find an operator keyword : `parse_operator_after_ret_type`
+5. otherwise :
+    1. `parse_identifier`
+    2. If we se a opening parenthesis (capture start), its a function : `parse_function_after_name`
+    3. Its a variable : `parse_variable_after_name`
+
+## `parse_pragma`
+
+1. Consume pragma directive
+2. Process the token content into cached string
+
+## `parse_params`
+
+1. Consume either a `(` or `<` based on `use_template_capture` arg
+2. If the we immdiately find a closing token, consume it and finish.
+3. If we encounter a varadic argument, consume it and return a `param_varadic` ast constant
+4. `parse_type`
+5. If we have a macro, parse it (Unreal has macros as tags to parameters and or as entire arguments).
+6. So long as next token isn't a comma
+  a. If we have an identifier
+    1. Consume it
+    2. Check for assignment:
+      a. Consume assign operator
+      b. Parse the expression
+7. While we continue to encounter commas
+    a. Consume them
+    b. Repeat steps 3 to 6.2.b
+8. Consume the closing token
+
+## `parse_preprocess_cond`
+
+1. Parse conditional directive
+2. Process directive's content expression
+
+## `parse_simple_preprocess`
+
+There is still decent room for improvement in this setup. Right now the entire macro's relevant tokens are shoved into an untyped AST. It would be better to store it instead in an `AST_Macro` node instead down the line.
+
+1. Consume the macro token
+2. Check for an opening curly brace
+    1. Consume opening curly brace
+    2. Until the closing curly is encountered consume all tokens.
+    3. If the parent context is a typedef
+        1. Check for end stement
+            1. Consume it
+            2. Consume potential inline comment
+3. Otherwise do steps 3 to 3.1.2
+4. Shove it all in an untyped string
+
+## `parse_static_assert`
+
+1. Consume static assert and opening curly brace
+2. Consume all tokens until the the closing brace is reached.
+3. Consume curly brace and end statement
+4. Place all tokens within braces into a content for the assert.
+
+## `parse_template_args`
+
+This will get changed heavily once we have better support for typename expressions
+
+1. Consume opening angle bracket
+2. Consume all tokens until closing angle bracket
+3. Consme closing angle bracket
+4. Return the currtok with the ammended length.
+
+## `parse_variable_after_name`
+
+This is needed as a variable defintion is not easily resolvable early on, it takes a long evaluation period before its known that the declaration or definition is a variable. As such this function handles resolving a variable.
+
+By the point this function is called the following are known : export module flag, attributes, specifiers, value type, name
+
+1. If its an assignment, parse the assignment expression (currently to an untyped string)
+2. If its an opening curly brace, parse the expression within (currnelty to an untyped stirng).

+
+## `parse_destructor`
+
+1. Check for and consume virtual specifier
+2. Check for the `~` operator
+3. `parse_identifier`
+4. Consume opening and closing parenthesis
+5. Check for assignment operator:
+    1. Consume assignment op
+    2. Consume pure specifier `0`
+6. If not pure virtual & currtok is opening curly brace:
+    1. `parse_function_body`
+7. Otherwise:
+    1. Consume end statement

+        1. Consume identifier
+        2. If there is an assignment operator:
+            1. Consume operator
+            2. Consume the expression (assigned to untyped string for now)
+            3. If a macro is encountered consume it (Unreal UMETA macro support)
+        3. If there is a comma, consume it

+## `parse_type`
+
+This function's implementation is awful and not done correctly. It will most likely be overhauled in the future as I plan to segement the AST_Type into several AST varaints along with sub-types to help produce robust type expressions.  
+Hopefully I won't need to make authentic type expressions as I was hopeing to avoid that...

+# Parsing
+
+The library features a naive parser tailored for only what the library needs to construct the supported syntax of C++ into its AST.
+
+This parser does not, and should not do the compiler's job. By only supporting this minimal set of features, the parser is kept (so far) around ~5600 loc. I hope to keep it under 10k loc worst case.
+
+You can think of this parser of a frontend parser vs a semantic parser. Its intuitively similar to WYSIWYG. What you precerive as the syntax from the user-side before the compiler gets a hold of it, is what you get.
+
+User exposed interface:
+
+```cpp
+CodeClass       parse_class        ( StrC class_def       );
+CodeConstructor parse_constructor  ( StrC constructor_def );
+CodeDestructor  parse_destructor   ( StrC destructor_def  );
+CodeEnum        parse_enum         ( StrC enum_def        );
+CodeBody        parse_export_body  ( StrC export_def      );
+CodeExtern      parse_extern_link  ( StrC exten_link_def  );
+CodeFriend      parse_friend       ( StrC friend_def      );
+CodeFn          parse_function     ( StrC fn_def          );
+CodeBody        parse_global_body  ( StrC body_def        );
+CodeNS          parse_namespace    ( StrC namespace_def   );
+CodeOperator    parse_operator     ( StrC operator_def    );
+CodeOpCast      parse_operator_cast( StrC operator_def    );
+CodeStruct      parse_struct       ( StrC struct_def      );
+CodeTemplate    parse_template     ( StrC template_def    );
+CodeType        parse_type         ( StrC type_def        );
+CodeTypedef     parse_typedef      ( StrC typedef_def     );
+CodeUnion       parse_union        ( StrC union_def       );
+CodeUsing       parse_using        ( StrC using_def       );
+CodeVar         parse_variable     ( StrC var_def         );
+```
+
+To parse file buffers, use the `parse_global_body` function.
+
+***Parsing will aggregate any tokens within a function body or expression statement to an untyped Code AST.***
+
+Everything is done in one pass for both the preprocessor directives and the rest of the language.  
+The parser performs no macro expansion as the scope of gencpp feature-set is to only support the preprocessor for the goal of having rudimentary awareness of preprocessor ***conditionals***,  ***defines***, ***includes***, and ***pragmas***.  
+
+The keywords supported for the preprocessor are:
+
+* include
+* define
+* if
+* ifdef
+* elif
+* endif
+* pragma
+
+Each directive `#` line is considered one preproecessor unit, and will be treated as one Preprocessor AST. *These ASTs will be considered members or entries of braced scope they reside within*.  
+If a directive is used with an unsupported keyword its will be processed as an untyped AST.
+
+The preprocessor lines are stored as members of their associated scope they are parsed within. ( Global, Namespace, Class/Struct )
+
+Any preprocessor definition abuse that changes the syntax of the core language is unsupported and will fail to parse if not kept within an execution scope (function body, or expression assignment).  
+Exceptions:
+
+* function signatures are allowed for a preprocessed macro: `neverinline MACRO() { ... }`
+  * Disable with: `#define GEN_PARSER_DISABLE_MACRO_FUNCTION_SIGNATURES`
+* typedefs allow for a preprocessed macro: `typedef MACRO();`
+  * Disable with: `#define GEN_PARSER_DISABLE_MACRO_TYPEDEF`
+
+*(Exceptions are added on an on-demand basis)*
+*(See functions `parse_operator_function_or_variable` and `parse_typedef` )*
+
+Adding your own exceptions is possible by simply modifying the parser to allow for the syntax you need.
+
+*Note: You could interpret this strictness as a feature. This would allow the user to see if their codebase or a third-party's codebase some some egregious preprocessor abuse.*
+
+The lexing and parsing takes shortcuts from whats expected in the standard.
+
+* Numeric literals are not checked for validity.
+* The parse API treats any execution scope definitions with no validation and are turned into untyped Code ASTs.
+  * *This includes the assignment of variables.*
+* Attributes ( `[[]]` (standard), `__declspec` (Microsoft), or `__attribute__` (GNU) )
+  * Assumed to *come before specifiers* (`const`, `constexpr`, `extern`, `static`, etc) for a function or right afterthe return type.
+  * Or in the usual spot for class, structs, (*right after the declaration keyword*)
+  * typedefs have attributes with the type (`parse_type`)
+* Parsing attributes can be extended to support user defined macros by defining `GEN_DEFINE_ATTRIBUTE_TOKENS` (see `gen.hpp` for the formatting)
+
+Empty lines used throughout the file are preserved for formatting purposes during ast serialization.

+## Documentation
+
+The project has no external dependencies beyond:
+
+* `errno.h`
+* `stat.h`
+* `stdarg.h`
+* `stddef.h`
+* `stdio.h`
+* `copyfile.h` (Mac)
+* `types.h`    (Linux)
+* `unistd.h`   (Linux/Mac)
+* `intrin.h`   (Windows)
+* `io.h`       (Windows with gcc)
+* `windows.h`  (Windows)
+
+Dependencies for the project are wrapped within `GENCPP_ROLL_OWN_DEPENDENCIES` (Defining it will disable them).  
+The majority of the dependency's implementation was derived from the [c-zpl library](https://github.com/zpl-c/zpl).
+
+This library was written in a subset of C++ where the following are not used at all:
+
+* RAII (Constructors/Destructors), lifetimes are managed using named static or regular functions.
+* Language provide dynamic dispatch, RTTI
+* Object-Oriented Inheritance
+* Exceptions
+
+Polymorphic & Member-functions are used as an ergonomic choice, along with a conserative use of operator overloads.  
+The base library itself does not use anything but C-like features to allow for generating a derviative compatiable with C (WIP).
+
+There are only 4 template definitions in the entire library. (`Array<Type>`, `Hashtable<Type>`, `swap<Type>`, and `AST/Code::cast<Type>`)
+
+Two generic templated containers are used throughout the library:
+
+* `template< class Type> struct Array`
+* `template< class Type> struct HashTable`
+
+Both Code and AST definitions have a `template< class Type> Code/AST :: cast()`. Its just an alternative way to explicitly cast to each other.
+
+`template< class Type> swap( Type& a, Type& b)` is used over a macro.
+
+Otherwise the library is free of any templates.
+
+### *WHAT IS NOT PROVIDED*
+
+**There is no support for validating expressions.**  
+Its difficult to parse without enough benefits (At the metaprogramming level).  
+I plan to add this only at the tail of the project parsing milestone.
+
+**Only trivial template support is provided.**  
+The intention is for only simple, non-recursive substitution.  
+The parameters of the template are treated like regular parameter AST entries.  
+This means that the typename entry for the parameter AST would be either:
+
+* `class`
+* `typename`
+* A fundamental type, function, or pointer type.
+
+Anything beyond this usage is not supported by parse_template for arguments (at least not intentionally).  
+Use at your own mental peril.
+
+*Concepts and Constraints are not supported, its usage is non-trivial substitution.*
+
+### The Data & Interface
+
+As mentioned in root readme, the user is provided Code objects by calling the constructor's functions to generate them or find existing matches.
+
+The AST is managed by the library and provided to the user via its interface.  
+However, the user may specifiy memory configuration.
+
+Data layout of AST struct (Subject to heavily change with upcoming redesign):
+
+```cpp
+union {
+    struct
+    {
+        AST*      InlineCmt;       // Class, Constructor, Destructor, Enum, Friend, Functon, Operator, OpCast, Struct, Typedef, Using, Variable

+*`CodeT` is a typedef for `ECode::Type` which has an underlying type of `u32`*  
+*`OperatorT` is a typedef for `EOperator::Type` which has an underlying type of `u32`*  
+*`StringCahced` is a typedef for `String const`, to denote it is an interned string*  
+*`String` is the dynamically allocated string type for the library*
+
+AST widths are setup to be AST_POD_Size.
+The width dictates how much the static array can hold before it must give way to using an allocated array:
+
+```cpp
+constexpr static
+usize ArrSpecs_Cap =
+(
+    AST_POD_Size
+    - sizeof(AST*) * 3
+    - sizeof(StringCached)
+    - sizeof(CodeT)
+    - sizeof(ModuleFlag)
+    - sizeof(u32)
+)
+/ sizeof(SpecifierT) -1; // -1 for 4 extra bytes (Odd num of AST*)
+```
+
+*Ex: If the AST_POD_Size is 128 the capacity of the static array is 20.*
+
+Data Notes:
+
+* The allocator definitions used are exposed to the user incase they want to dictate memory usage
+  * You'll find the memory handling in `init`, `deinit`, `reset`, `gen_string_allocator`, `get_cached_string`, `make_code`.
+  * Allocators are defined with the `AllocatorInfo` structure found in `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 );
+```
+
+* ASTs are wrapped for the user in a Code struct which is a wrapper for a AST* type.
+* Both AST and Code have member symbols but their data layout is enforced to be POD types.
+* This library treats memory failures as fatal.
+* Cached Strings are stored in their own set of arenas. AST constructors use cached strings for names, and content.
+  * `StringArenas`, `StringCache`, `Allocator_StringArena`, and `Allocator_StringTable` are the associated containers or allocators.
+* Strings used for serialization and file buffers are not contained by those used for cached strings.
+  * They are currently using `GlobalAllocator`, which are tracked array of arenas that grows as needed (adds buckets when one runs out).
+  * Memory within the buckets is not reused, so its inherently wasteful.
+  * I will be augmenting the single arena with a simple slag allocator.
+* Linked lists used children nodes on bodies, and parameters.
+* Its intended to generate the AST in one go and serialize after. The constructors and serializer are designed to be a "one pass, front to back" setup.
+* Allocations can be tuned by defining the folloiwng macros:
+  * `GEN_GLOBAL_BUCKET_SIZE` : Size of each bucket area for the global allocator
+  * `GEN_CODEPOOL_NUM_BLOCKS` : Number of blocks per code pool in the code allocator
+  * `GEN_SIZE_PER_STRING_ARENA` : Size per arena used with string caching.
+  * `GEN_MAX_COMMENT_LINE_LENGTH` : Longest length a comment can have per line.
+  * `GEN_MAX_NAME_LENGTH` : Max length of any identifier.
+  * `GEN_MAX_UNTYPED_STR_LENGTH` : Max content length for any untyped code.
+  * `GEN_TOKEN_FMT_TOKEN_MAP_MEM_SIZE` : token_fmt_va uses local_persit memory of this size for the hashtable.
+  * `GEN_LEX_ALLOCATOR_SIZE`
+  * `GEN_BUILDER_STR_BUFFER_RESERVE`
+
+The following CodeTypes are used which the user may optionally use strong typing with if they enable: `GEN_ENFORCE_STRONG_CODE_TYPES`
+
+* CodeBody : Has support for `for-range` iterating across Code objects.
+* CodeAttributes
+* CodeComment
+* CodeClass
+* CodeConstructor
+* CodeDefine
+* CodeDestructor
+* CodeEnum
+* CodeExec
+* CodeExtern
+* CodeInclude
+* CodeFriend
+* CodeFn
+* CodeModule
+* CodeNS
+* CodeOperator
+* CodeOpCast
+* CodeParam : Has support for `for-range` iterating across parameters.
+* CodePreprocessCond
+* CodePragma
+* CodeSpecifiers : Has support for `for-range` iterating across specifiers.
+* CodeStruct
+* CodeTemplate
+* CodeType
+* CodeTypedef
+* CodeUnion
+* CodeUsing
+* CodeVar
+
+Each Code boy has an associated "filtered AST" with the naming convention: `AST_<CodeName>`
+Unrelated fields of the AST for that node type are omitted and only necessary padding members are defined otherwise.
+Retrieving a raw version of the ast can be done using the `raw()` function defined in each AST.
+
+## There are three sets of interfaces for Code AST generation the library provides
+
+* Upfront
+* Parsing
+* Untyped
+
+### Upfront Construction
+
+All component ASTs must be previously constructed, and provided on creation of the code AST.
+The construction will fail and return CodeInvalid otherwise.
+
+Interface :``
+
+* def_attributes
+  * *This is pre-appended right before the function symbol, or placed after the class or struct keyword for any flavor of attributes used.*
+  * *Its up to the user to use the desired attribute formatting: `[[]]` (standard), `__declspec` (Microsoft), or `__attribute__` (GNU).*
+* def_comment
+* def_class
+* def_constructor
+* def_define
+* def_destructor
+* def_enum
+* def_execution
+  * *This is equivalent to untyped_str, except that its intended for use only in execution scopes.*
+* def_extern_link
+* def_friend
+* def_function
+* def_include
+* def_module
+* def_namespace
+* def_operator
+* def_operator_cast
+* def_param
+* def_params
+* def_pragma
+* def_preprocess_cond
+* def_specifier
+* def_specifiers
+* def_struct
+* def_template
+* def_type
+* def_typedef
+* def_union
+* def_using
+* def_using_namespace
+* def_variable
+
+Bodies:
+
+* def_body
+* def_class_body
+* def_enum_body
+* def_export_body
+* def_extern_link_body
+* def_function_body
+  * *Use this for operator bodies as well*
+* def_global_body
+* def_namespace_body
+* def_struct_body
+* def_union_body
+
+Usage:
+
+```cpp
+<name> = def_<function type>( ... );
+
+Code <name>
+{
+    ...
+    <name> = def_<function name>( ... );
+}
+
+```
+
+When using the body functions, its recommended to use the args macro to auto determine the number of arguments for the varadic:
+```cpp
+def_global_body( args( ht_entry, array_ht_entry, hashtable ));
+
+// instead of:
+def_global_body( 3, ht_entry, array_ht_entry, hashtable );
+```
+
+If a more incremental approach is desired for the body ASTs, `Code def_body( CodeT type )` can be used to create an empty body.  
+When the members have been populated use: `AST::validate_body` to verify that the members are valid entires for that type.
+
+### Parse construction
+
+A string provided to the API is parsed for the intended language construct.
+
+Interface :
+
+* parse_class
+* parse_constructor
+* parse_destructor
+* parse_enum
+* parse_export_body
+* parse_extern_link
+* parse_friend
+  * Purposefully are only support forward declares with this constructor.
+* parse_function
+* parse_global_body
+* parse_namespace
+* parse_operator
+* parse_operator_cast
+* parse_struct
+* parse_template
+* parse_type
+* parse_typedef
+* parse_union
+* parse_using
+* parse_variable
+
+Usage:
+
+```cpp
+Code <name> = parse_<function name>( string with code );
+
+Code <name> = def_<function name>( ..., parse_<function name>(
+    <string with code>
+));
+```
+
+### Untyped constructions
+
+Code ASTs are constructed using unvalidated strings.
+
+Interface :
+
+* token_fmt_va
+* token_fmt
+* untyped_str
+* untyped_fmt
+* untyped_token_fmt
+
+During serialization any untyped Code AST has its string value directly injected inline of whatever context the content existed as an entry within.  
+Even though these are not validated from somewhat correct c/c++ syntax or components, it doesn't mean that Untyped code can be added as any component of a Code AST:
+
+* Untyped code cannot have children, thus there cannot be recursive injection this way.
+* Untyped code can only be a child of a parent of body AST, or for values of an assignment (ex: variable assignment).
+
+These restrictions help prevent abuse of untyped code to some extent.
+
+Usage Conventions:
+
+```cpp
+Code <name> = def_variable( <type>, <name>, untyped_<function name>(
+    <string with code>
+));
+
+Code <name> = untyped_str( code(
+    <some code without "" quotes>
+));
+```
+
+Optionally, `code_str`, and `code_fmt` macros can be used so that the code macro doesn't have to be used:
+```cpp
+Code <name> = code_str( <some code without "" quotes > )
+```
+
+Template metaprogramming in the traditional sense becomes possible with the use of `token_fmt` and parse constructors:
+
+```cpp
+StrC value = txt("Something");
+
+char const* template_str = txt(
+    Code with <key> to replace with token_values
+    ...
+);
+char const* gen_code_str = token_fmt( "key", value, template_str );
+Code        <name>       = parse_<function name>( gen_code_str );
+```
+
+## Predefined Codes
+
+The following are provided predefined by the library as they are commonly used:
+
+* `access_public`
+* `access_protected`
+* `access_private`
+* `attrib_api_export`
+* `attrib_api_import`
+* `module_global_fragment`
+* `module_private_fragment`
+* `fmt_newline`
+* `param_varaidc` (Used for varadic definitions)
+* `pragma_once`
+* `preprocess_else`
+* `preprocess_endif`
+* `spec_const`
+* `spec_consteval`
+* `spec_constexpr`
+* `spec_constinit`
+* `spec_extern_linkage` (extern)
+* `spec_final`
+* `spec_forceinline`
+* `spec_global` (global macro)
+* `spec_inline`
+* `spec_internal_linkage` (internal macro)
+* `spec_local_persist` (local_persist macro)
+* `spec_mutable`
+* `spec_neverinline`
+* `spec_override`
+* `spec_ptr`
+* `spec_pure`
+* `spec_ref`
+* `spec_register`
+* `spec_rvalue`
+* `spec_static_member` (static)
+* `spec_thread_local`
+* `spec_virtual`
+* `spec_volatile`
+* `t_empty` (Used for varaidc macros)
+* `t_auto`
+* `t_void`
+* `t_int`
+* `t_bool`
+* `t_char`
+* `t_wchar_t`
+* `t_class`
+* `t_typename`
+
+Optionally the following may be defined if `GEN_DEFINE_LIBRARY_CODE_CONSTANTS` is defined
+
+* `t_b32`
+* `t_s8`
+* `t_s16`
+* `t_s32`
+* `t_s64`
+* `t_u8`
+* `t_u16`
+* `t_u32`
+* `t_u64`
+* `t_sw` (ssize_t)
+* `t_uw` (size_t)
+* `t_f32`
+* `t_f64`
+
+## Extent of operator overload validation
+
+The AST and constructors will be able to validate that the arguments provided for the operator type match the expected form:
+
+* If return type must match a parameter
+* If number of parameters is correct
+* If added as a member symbol to a class or struct, that operator matches the requirements for the class (types match up)
+* There is no support for validating new & delete operations (yet)
+
+The user is responsible for making sure the code types provided are correct
+and have the desired specifiers assigned to them beforehand.
+
+## Code generation and modification
+
+There are three provided auxillary interfaces:
+
+* Builder
+* Editor
+* Scanner
+
+Editor and Scanner are disabled by default, use `GEN_FEATURE_EDITOR` and `GEN_FEATURE_SCANNER` to enable them.
+
+### Builder is a similar object to the jai language's string_builder
+
+* The purpose of it is to generate a file.
+* A file is specified and opened for writing using the open( file_path) function.
+* The code is provided via print( code ) function  will be serialized to its buffer.
+* When all serialization is finished, use the write() command to write the buffer to the file.
+
+### Scanner Auxillary Interface
+
+Provides *(eventually)* `scan_file` to automatically populate a CodeFile which contains a parsed AST (`Code`) of the file, with any contextual failures that are reported from the parser.

-All the library code is contained in two files: `gen.hpp` and `gen.cpp`
+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.
 
-## gen.hpp
+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>`
+
+Code not making up the core library is located in `auxiliary/<auxiliary_name>.<hpp/cpp>`. These are optional extensions or tools for the library.
+
+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_ROLL_OWN_DEPENDENCIES` : Optional override so that user may define the dependencies themselves.
+* `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_FEATURE_PARSING` : Defines the parse constructors
-* `GEN_FEATURE_EDITOR` : Defines the file editing features for changing definitions based on ASTs
-* `GEN_FEATURE_SCANNER` : Defines the file scanning features for generating ASTs
+* `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.
+* `GEN_DONT_ALLOW_INVALID_CODE` (Not implemented yet) : Will fail when an invalid code is constructed, parsed, or serialized.
 
-`GEN_USE_RECURSIVE_AST_DUPLICATION` is available but its not well tested and should not need to be used.
-If constructing ASTs properly. There should be no modification of ASTs, and thus this would never become an issue.
+By default the base library implementation strictly uses a C-like interface. This is to allow for the generation of a C-variant of the library using [gen_c_library](../gen_c_library/). However, the library was written in C++ and supports some of its features:
 
-Due to the design of `gen.hpp` to support being written alongside runtime intended code (in the same file), all the code is wrapped in a `gen_time` `#ifdef` and then wrapped further in a `gen` namespace to avoid pollution of the global scope.
+* `GEN_SUPPORT_CPP_REFERENCES` : Will enable support for reference interface on some definitions
+* `GEN_SUPPORT_CPP_MEMBER_FEATURES` : Will enable support for definitions to have their interface as members.
 
-*Note: Its possible with the scanner feature to support parsing runtime files that use "generic" macros or identifiers with certain patterns.  
-This can be used to auto-queue generation of dependent definitions for the symbols used.*
+*Note: A variant of the C++ library could be generated where those additonal support features are removed (see gen_c_library implementation for an idea of how)*
 
-### Organization
+## On multi-threading
 
-Dependencies : Mostly from the c-zpl library.
+Currently unsupported. I want the library to be *stable* and *correct*, with the addition of exhausting all basic single-threaded optimizations before I consider multi-threading.
 
-log_failure definition : based on whether to always use fatal on all errors
+## Extending the library
 
-Major enum definitions and their associated functions used with the AST data
+This library is relatively very small, and can be extended without much hassle.
 
-* `ECode` : Used to tag ASTs by their type
-* `EOperator` : Used to tag operator overloads with thier op type
-* `ESpecifier` : Used with specifier ASTs for all specifiers the user may tag an associated
-AST with.
-* `AccessSpec` : Used with class and struct ASTs to denote the public, protected, or private fields.
-* `EnumT` : Used with def_enum to determine if constructing a regular enum or an enum class.
-* `ModuleFlag` : Used with any valid definition that can have export or import related keywords assoicated with it.
+The convention you'll see used throughout the interface of the library is as follows:
 
-#### Data Structures
+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).
 
-`StringCache` : Hash table for cached strings. (`StringCached` typedef used to denote strings managed by it)
+Names or Content fields are interned strings and thus showed be cached using `get_cached_string` if its desired to preserve that behavior.
 
-`Code` : Wrapper for `AST` with functionality for handling it appropriately.  
-`AST` : The node data strucuture for the code.  
-`Code Types` : Codes with typed ASTs. Body, Param, and Specifier have unique implementation, the rest use `Define_CodeType`  
-`AST Types` : Filtered AST definitions.  
+`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.
 
-#### Gen Interface
+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.
 
-First set of fowards are either backend functions used for various aspects of AST generation or configurating allocators used for different containers.
+The parser is documented under `docs/Parsing.md` and `docs/Parser_Algo.md`.
 
-Interface fowards defined in order of: Upfront, Parsing, Untyped.
+## A note on compilation and runtime generation speed
 
-From there forwards for the File handlers are defined: Builder, Editor, Scanner.
-
-#### Macros
-
-General helper macros are defined along with the optional DSL macros.
-
-#### Constants
-
-Constants including optional ones are defined.
-
-#### Inlines
-
-Inlined functions related to the AST datatype that required forwards for gen interface functions are defined.
-
-## gen.cpp
-
-* Dependencies
-* Static data
-* AST Body case macros are next.
-* AST implementation
-* Gen interface begins with its `init`, `deinit`, etc.. Until `make_code_entires`
-* operator__validate defined, which will be used to verify if an operator definition is constructible.
-* Allocator interface for data arrays, code pool, code entries, string arenas, and string table.
-* Helper macros used throughout the constructor API
-* Upfront constructors, following the same order as shown in the header.
-* Parsing constructors, it defines its own lexer, and has many helper functions for parsing not exposed through the header.
-* Untyped constructors
-* Builder
-* Editor
-* Scanner
+The library is designed to be fast to compile and generate code at runtime as fast as resonable possible on a debug build.
+Its recommended that your metaprogam be compiled using a single translation unit (unity build).
