 ## 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 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 [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 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.
-* When benchmarking, the three most significant var to tune are:
-  * `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 string 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 explicitly cast to each other.
-
-Otherwise the library is free of any templates.
-
-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
-* CodeEnum
-* CodeExec
-* CodeExtern
-* CodeInclude
-* CodeFriend
-* CodeFn
-* CodeModule
-* CodeNamespace
-* CodeOperator
-* CodeOpCast
-* CodeParam : Has support 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 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 Code::Invalid 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_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 constructors, 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_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_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 );
-```
-

-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`

-
-## 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 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.
-
-### 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 writing 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 access with fences if more than one thread will generate ASTs ( or keep a different set for each thread)
-* Make sure local persistent 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 receipts 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 serialization function `to_string`, follow the order at which entires are expected to appear (there is a strong ordering expected).
-
-Names or Content fields are interned strings and thus showed be cached using `get_cached_string` if its desired to preserve that behavior.
-
-`def_operator` is the most sophisticated constructor as it has multiple permutations of definitions that could be created that are not trivial to determine if valid.
-
-# TODO
-
-* Support defining & parsing full definitions inside a typedef. (For C patterns)
-* Support module and attribute parsing (Marked with TODOs for now..)
-* Implement a context stack for the parsing, allows for accurate scope validation for the AST types.
-* Trailing specifiers ( postfix ) for functions (const, override, final)
-* Make a more robust test suite.
-* Generate a single-header library
-  * Componetize the library, make a metaprogram using gencpp to bootstrap itself.
-* Implement the Scanner
-* Implement the Editor
-* Should the builder be an "extension" header?
-  * Technically the library doesn't require it and the user can use their own filesystem library.
-  * It would allow me to remove the filesystem dependencies and related functions outside of gen base headers. ( At least 1k loc reduced )
-  * ADT and the CSV parser depend on it as well. The `str_fmt_file` related functions do as well but they can be ommited.
-  * Scanner and editor will also depend on it so they would need to include w/e the depency header for all three file-interacting interfaces.
-    * `gen.dep.files.hpp`
-* Convert GlobalAllocator to a slab allocator:
-
-```md
-Slab classes (for 10 mb arena)
-
-1KB   slab: 5MB  ( 5MB  / 1KB   ~ 5,000 blocks )
-4KB   slab: 10MB ( 10MB / 4KB   ~ 2,500 blocks )
-16KB  slab: 15MB ( 15MB / 16KB  ~ 960 blocks   )
-64KB  slab: 15MB ( 15MB / 64KB  ~ 240 blocks   )
-256KB slab: 20MB ( 20MB / 256KB ~ 80 blocks    )
-512KB slab: 20MB ( 20MB / 512KB ~ 40 blocks    )
-1MB   slab: 15MB ( 15MB / 1MB   ~ 15 blocks    )

+# 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) under 5000 loc.
+
+The parsing implementation supports the following for the user:
+
+```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         );
+```
+
+***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***, and ***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() { ... }`
+* typedefs allow for a preprocessed macro: `typedef MACRO();`
+
+*(See functions `parse_operator_function_or_variable` and `parse_typedef` )*
+
+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 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 constructors, 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.*
+* 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.  
+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).  
+
+**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:
+
+```cpp
+union {
+    struct
+    {
+        AST*      Attributes;      // Class, Enum, Function, Struct, Typedef, Union, Using, Variable
+        AST*      Specs;           // Function, Operator, Type symbol, Variable
+        union {
+            AST*  InitializerList; // Constructor, Destructor
+            AST*  ParentType;      // Class, Struct
+            AST*  ReturnType;      // Function, Operator
+            AST*  UnderlyingType;  // Enum, Typedef
+            AST*  ValueType;       // Parameter, Variable
+        };
+        union {
+            AST*  BitfieldSize;    // Varaiable (Class/Struct Data Member)
+            AST*  Params;          // Function, Operator, Template
+        };
+        union {
+            AST*  ArrExpr;         // Type Symbol
+            AST*  Body;            // Class, Constructr, Destructor, 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;
+    AST* Last;
+};
+union {
+    AST* Next;
+    AST* Back;
+};
+AST*              Parent;
+StringCached      Name;
+CodeT             Type;
+ModuleFlag        ModuleFlags;
+union {
+    b32           IsFunction; // Used by typedef to not serialize the name field.
+    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(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`.
+* 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_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`
+* `pragma_once`
+* `param_varaidc` (Used for varadic definitions)
+* `preprocess_else`
+* `preprocess_endif`
+* `spec_const`
+* `spec_consteval`
+* `spec_constexpr`
+* `spec_constinit`
+* `spec_extern_linkage` (extern)
+* `spec_final`
+* `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`
+* `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 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.
+
+### Editor is for editing a series of files/asts 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.
+* If editing an AST it will generate a new ast as a result (ASTs are not edited).
+* 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 sift through a series of files/asts based on a set of requests provided to it
+
+**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 writing supported.
+
+### 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.

 # Documentation
 
-The core library is contained within `gen.hpp` and `gen.cpp`.
-Things related to the editor and scanner are in their own respective files. (Ex: `gen.scanner.<hpp/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.
 
+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>`
 
-## gen.hpp
+The fle processors are in their own respective files. (Ex: `file_processors/<file_processor>.<hpp/cpp>` )  
+They directly include `depedencies/file_handling.<hpp/cpp>` as the core library does not include file processing by defualt.
+
+**TODO : Right now the library is not finished, as such the first self-hosting iteration is still WIP**  
+Both libraries use *pre-generated* (self-hosting I guess) version of the library to then generate the latest version of itself.  
+
+The default `gen.bootstrap.cpp` located in the project folder is meant to be produce a standard segmented library, where the components of the library  
+have relatively dedicated header and source files. Dependencies included at the top of the file and each header starting with a pragma once.  
+The output will be in the `project/gen` directory (if the directory does not exist, it will create it).
+
+Use those to get a general idea of how to make your own tailored version.
 
 Feature Macros:
 
-* `GEN_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_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_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_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.  
-(I will probably remove down the line...)
+## On multi-threading
 
-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.
+Currently unsupported.
 
-*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.*
+## Extending the library
 
-### Organization
+This library is relatively very small, and can be extended without much hassle.
 
-Dependencies : Mostly from the c-zpl library.
+The convention you'll see used throughout the interface of the library is as follows:
 
-log_failure definition : based on whether to always use fatal on all errors
+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).
 
-Major enum definitions and their associated functions used with the AST data
+Names or Content fields are interned strings and thus showed be cached using `get_cached_string` if its desired to preserve that behavior.
 
-* `ECode` : Used to tag ASTs by their type
-* `EOperator` : Used to tag operator overloads with their 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 associated with it.
+`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.
 
-#### Data Structures
+The library has its code segmented into component files, use it to help create a derived version without needing to have to rewrite a generated file directly or build on top of the header via composition or inheritance.
+When the scanner is implemented, this will be even easier to customize.
 
-`StringCache` : Hash table for cached strings. (`StringCached` typedef used to denote strings managed by it)
-
-`Code` : Wrapper for `AST` with functionality for handling it appropriately.  
-`AST` : The node data structure 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.  
-
-#### Gen Interface
-
-First set of forwards are either backend functions used for various aspects of AST generation or configurations allocators used for different containers.
-
-Interface forwards defined in order of: Upfront, Parsing, Untyped.
-
-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

 # Scripts
 
-Build and cleanup scripts for the test directory are found here along with `natvis` and `natstepfilter` files for debugging.
+Generation, testing, and cleanup scripts for the test directory are found here along with `natvis` and `natstepfilter` files for debugging.
 
-The build works as follows:
+## Refactoring
 
-* Compile and run the meta-program, it will dump files to the `test/gen` directory.
-* Format the files using clang-format
-* Build a program that uses some the generated definitions. (Have not done yet)
+`refactor.ps1` Provides a way to run the [refactor](github.com/Ed94/refactor) program. It uses the `gencpp.refactor` script to complete a mass refactor of all content within the files of the specified within the script.
 
-The `test/gen` directory has the meson.build config for the meta-program
-The `test` directory has the one for the dependent-program.
+Currently `refactor` only supports naive sort of *find and replace* feature set and will not be able to rename identifiers excluisvely to a specific context (such as only renaming member names of a specific struct, etc).
+
+**Note: The following macros are used with specifiers and token parsing within the library:**
+
+* global
+* internal
+* local_persist
+* forceinline
+* neverinline
+
+IF they are changed the following files would need adjustment:
+
+* `./project/enums/ESpecifier.csv`
+* `./project/enums/ETokType.csv`
+* `./project/helpers/helper.hpp`
+
+## Build & Run Scripts
+
+**`clean.ps1`**  
+Remove any generated content from the repository.
+
+**`build.ps1`**  
+Build bootstrap, singleheader, or tests. Supports MSVC or clang, release or debug.
+
+```
+args:
+    bootstrap
+    singleheader
+    test
+    clang
+    msvc    : By default this project builds with clang, specifying msvc will build with MSVC.
+    debug
+    release : By default this project builds in debug mode, specifying release will build with optimizations.
+```
+
+**`package_release.ps1`**  
+Will build the project as fast as possible, then package the release into a zip file.
+
+*Note: My env is Windows 11 with MSVC 2022 and clang 16.0.6*

 # Test
 
-The following tests focus on attempting to generate some math, containers, and the memory module of zpl.
+The implementaiton here is not well organized and needs a rewrite..
 
-Not all the files are written how I would practically use the library, the containers for example would
-be better on in c++ as templates, since the templates they generate are trivial symbols to inspect or debug.
-
-An example of a non-trivial generation is a container for elements with SOA or AOS policy for layout.
-(If a unified element syntax is desired)
-
-The test is divided between two major sets of tests: Parsed and Upfront.
+I only do basic sanity and parsing tests for the most part.  
+The library is getting practical usage tests in [genc](https://github.com/Ed94/genc) and other projects.
