 ## Notes
 
-**On Partial Hiatus: Life has got me tackling other issues..**  
-I will be passively updating the library with bug fixes and minor improvements as I use it for my personal projects.  
-There won't be any major reworks or features to this thing for a while.
-
 This project is still in development (very much an alpha state), so expect bugs and missing features.  
 See [issues](https://github.com/Ed94/gencpp/issues) for a list of known bugs or todos.
 
 The library can already be used to generate code just fine, but the parser is where the most work is needed. If your C++ isn't "down to earth" expect issues.
 
 A `natvis` and `natstepfilter` are provided in the scripts directory (its outdated, I'll update this readme when its not).  
-
-***The editor and scanner have not been implemented yet. The scanner will come first, then the editor.***
-
-A C variant is hosted [here](https://github.com/Ed94/genc); I will complete it when this library is feature complete, it should be easier to make than this...
+*Minor update: I've been using [RAD Debugger](https://github.com/EpicGamesExt/raddebugger) with this and the code structures should be easy to debug even without natvis.*
 
 ## Usage
 
 A metaprogram is built to generate files before the main program is built. We'll term runtime for this program as `GEN_TIME`. The metaprogram's core implementation are within `gen.hpp` and `gen.cpp` in the project directory.
 
-`gen.cpp` \`s  `main()` is defined as `gen_main()` which the user will have to define once for their program. There they will dictate everything that should be generated.

+
+The library is fragmented into a series of headers and source files meant to be scanned in and then generated to a standard target format, or a user's desires.
+
+If using the library's provided build scripts:
+
+```ps1
+.\build.ps1 <compiler> <debug or omit> base
+```
+
+## Content Overview
+
+* **base**: Files are in granular pieces separated into four directories:
+  * **dependencies**: Originally from the c-zpl library and modified thereafter.
+  * **components**: The essential definitions of the library.
+  * **helpers**: Contains helper functionality used by base and the variant library generators.
+    * `base_codegen.hpp`: Helps with self-hosted code generation of enums, and operator overload inlines of the code types.
+    * `<push/pop>.<name>.inline.<hpp>`: macros that are meant to be injected at specific locations of the library file/s.
+    * `misc.hpp`: Misc functionality used by the library generation metaprograms.
+    * `undef.macros.h`: Undefines all macros from library.
+  * **auxiliary**: Non-essential tooling:
+    * `Builder`: Similar conceptually to Jai programming language's *builder*, just opens a file and prepares a string buffer to serialize code into (`builder_print`, `builder_print_fmt`). Then write & close the file when completed (`builder_write`).
+    * **`Scanner`**: Interface to load up `Code` from files two basic functions are currently provided.
+      * `scan_file`: Used mainly by the library format generators to directly scan files into untyped `Code` (raw string content, pre-formatted no AST parsed).
+      * `parse_file`: Used to read file and then parsed to populate a `CodeBody` AST.
+      * CSV parsing via one or two columns simplified.
+* **gen_segemetned**: Dependencies go into gen.dep.{hpp/cpp} and components into gen.{hpp/cpp}
+* **gen_singleheader**: Everything into a single file: gen.hpp
+* **gen_unreal_engine**: Like gen_segmented but the library is modified slightly to compile as a thirdparty library within an Unreal Engine plugin or module.
+* **gen_c_library**: The library is heavily modifed into C11 compliant code. A segmented and single-header set of variants are generated.
+
+Code not making up the core library is located in `auxiliary/<auxiliary_name>.<hpp/cpp>`. These are optional extensions or tools for the library.
+
+## Dependencies
+
+The project has no external dependencies beyond:
+
+* `errno.h`
+* `stat.h`
+* `stdarg.h`
+* `stddef.h`
+* `stdio.h`
+* `copyfile.h` (Mac)
+* `types.h`    (Linux)
+* `sys/man.h`  (Linux)
+* `fcntl.h`    (POSXIX Filesystem)
+* `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).
+
+See the following files for any updates:
+
+* [`platform.hpp`](./dependencies/platform.hpp)
+* [`src_start.cpp`](./dependencies/src_start.cpp)
+* [`filesystem.cpp`](./dependencies/filesystem.cpp)
+* [`memory.cpp`](./dependencies/memory.cpp)
+
+## Conventions
+
+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.
+
+Member function support or free-functions with reference object passing are wrapped in `! GEN_C_LIKE CPP` preprocess conditionals.
+
+## C++ template usage
+
+There are only 4 template definitions in the entire library (C++ versions). (`Array<Type>`, `Hashtable<Type>`, `swap<Type>`, and `tmpl_cast<CodeT>(CodeT code)`)
+
+Two generic templated containers are used throughout the library:
+
+* `template< class Type> struct Array`
+* `template< class Type> struct HashTable`
+
+`tmpl_cast<CodeT>(CodeT code)` is just an alternative way to explicitly cast to code. Its usage is wrapped in a macro called `cast` for the base library (needed for interoperability with C).
+
+`template< class Type> swap( Type& a, Type& b)` is used over a macro.
+
+Otherwise the library is free of any templates.
+
+## Macro usage
+
+Since this is a meta-programming library, it was desired to keep both templates and macros (especially macros) usage very limited.
+
+Most macros are defined within [macros.hpp](./dependencies/macros.hpp). 
+
+The most advanced macro usage is `num_args` which is a helper for counting the number of arguments of another macro.
+
+Any large macros used implementing the gen interface or parser are going to be phased out in favor of just forcinlined functions.  
+*(Unless there is a hot-path that requires them)*
+
+The vast majority of macros should be single-line subsitutions that either add:
+
+* Improvements to searching
+* Intentionality of keyword usage
+* A  feature that only the preprocessor has (ex: function name reflection or stringifying)
+* Compatibility of statements or expressions bewteen C & C++ that cannot be parsed by gencpp itself.
+* Masking highly verbose syntax (the latter is getting phased out).
+
+[gen_c_library](../gen_c_library/) has the most advanced set of macros for c11's generic selection.
+
+* A significant amount of explicit code geneeration is utilized to keep abuse of the preprocessor to the absolute minimum.
+* There is a heavy set of documentation inlined wth them; their naming is also highly verbose and explicit.
+* See its documentation for more information.
+
+## On base code generation
+
+There are ***five*** header files which are automatically generated using [base_codegen.hpp](./helpers/base_codegen.hpp) by [base.cpp](./base.cpp). They are all located in [components/gen](./components/gen/).
+
+* [ecodetypes.hpp](./components/gen/ecode.hpp): `CodeType` enum definition and related implementation. Generation is based off of [ECodeType.csv](./enums/ECodeTypes.csv).
+* [especifier.hpp](./components/gen/especifier.hpp): `Specifier` enum definition, etc. Generated using [ESpecifier.csv](./enums/ESpecifier.csv).
+* [eoperator.hpp](./components/gen/eoperator.hpp): `Operator` enum definition, etc. Generated using [EOperator.hpp](./enums/EOperator.csv).
+* [etoktype.cpp](./components/gen/etoktype.cpp): `TokType` enum defininition, etc. Used by the lexer and parser backend. Uses two csvs:
+  * [ETokType.csv](./enums/ETokType.csv): Provides the enum entries and their strinng ids.
+  * [AttributeTokens.csv](./enums/AttributeTokens.csv): Provides tokens entries that should be considered as attributes  by the lexer and parser. Sspecfiically macro attributes such as those use for exporting symbols.
+* [ast_inlines.hpp](./components/gen/ast_inlines.hpp): Member trivial `operator` definitions for C++ code types. Does not use a csv.
+
+[misc.hpp](./helpers/misc.hpp): Has shared functions used by the library generation meta-programs throughout this codebase.
+
+If using the library's provided build scripts:
+
+```ps1
+.\build.ps1 <compiler> <debug or omit> base
+```
+
+Will refresh those files.

+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.
+
+## Extending the library
+
+This library is relatively very small (for parsing C++), and can be extended without much hassle.
+
+The convention you'll see used throughout the upfront interface 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_strbuilder`, 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 `cache_str` if its desired to preserve that behavior.
+
+`def_operator` is the most sophisticated upfront constructor as it has multiple permutations of definitions that could be created that are not trivial to determine if valid.
+
+The parser is documented under [`docs/Parsing.md`](../docs/Parsing.md) and [`docs/Parser_Algo.md`](../docs/Parser_Algo.md). Read that and the entire library if you want to extend it.
+
+### Attributes
+
+To add additional macro attributes, all that has to be done is modifying [`AttributeTokens.csv`](./enums/AttributeTokens.csv).
+
+### Specifiers
+
+To add additional macro specifiers, the following needs to be done:
+
+1. Adjust [especifier.hpp](./components/gen/especifier.hpp)
+2. Adjust [etoktype.cpp](./components/gen/etoktype.cpp)
+3. Adjust [parser_case_macros.cpp](./components/parser_case_macros.cpp)
+
+If the specifier is a new trailing specifier on function definitions:
+
+Head into [base_codegen.hpp](./helpers/base_codegen.hpp): `gen_especifier`. There will be an `is_trailing` function that needs to be adjusted with an additional case for the user's new trailing specifier.
+
+### Code Types
+
+These require the following to be handled to the equivalent extent as the other types:
+
+1. Adjust [ECodeTypes.csv](./enums/ECodeTypes.csv) with the new types
+2. Define a new `AST_<Name>` and `Code<Name>`. See
+    * [ast.hpp](./components/ast.hpp): Initial forwards and user defined conversion for Code.
+    * [ast_types.hpp](./components/ast_types.hpp): Define the `AST_<Name>` struct.
+    * [code_types.hpp](./components/code_types.hpp): Defne the `CodeType` struct. If its needs an iterator see: `struct CodeBody` & `struct CodeParams`.
+3. [ast_case_macros.cpp](./components/ast_case_macros.cpp): Review cases here if the new code type needs to be considered.
+4. [ast.cpp](./components/ast.cpp): Need to review
+    * `code_debug_str`
+    * `code_is_equal`
+    * `code_to_strbuilder_ref`
+    * `code_validate_body`
+5. [code_serialization.cpp](./components/code_serialization.cpp): Define serialization here.
+6. [inlines.hpp](./components/inlines.hpp): Any inline definitions for the `struct Code<Name>` are defined here.
+7. [interface.cpp](./components/interface.hpp): Define the `Code<Name>` upfront and parsing interface.
+8. [interface.upfront.cpp](./components/interface.upfront.cpp): Define the upfront constructor implementation.
+9. [interface.parsing.cpp](./components/interface.parsing.cpp): Define the parsing interface implementation.
+10. [lexer.cpp](./components/lexer.cpp): Adjust the lexer as needed.
+11. [parser.cpp](./components/parser.cpp): Adjust the parser as needed.
+
+## A note on compilation and runtime generation speed
+
+The library is designed to be fast to compile and generate code at runtime as fast as possible on a debug build.
+Its recommended that your metaprogam be compiled using a single translation unit (unity build).
+
+## Whats with the expression / executions support #ifd and enums?
+
+The library is a *work in progress* and those are unfinished hypotheticals for adding the ability to manage or parse the AST of expresions or execution scope code.
+They are entirely untested and not meant to be used yet, futher there is no parsing support or an upfront interface for what CodeTypes are defined so far.

 ## 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*` its wrapped in a Code type which can be either:
 
-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*;
+When its the [C generated variant of the library](../gen_c_library/)
+```c
+typedef AST* Code;
+typedef AST_<name>* Code<name>;
+...
 ```
 
-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.
+**or**
 
+For C++:
 ```cpp
-using struct AST_Typedef CodeTypedef;
+struct Code {
+    AST* ast;
+};
+struct Code<name> {
+    ...
+
+    AST_<name>* ast;
+};
 ```
 
-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 full definitions of all asts are within:
 
-The redesign will occur after the following todos are addressed:
+* [`ast.hpp`](../base/components/ast.hpp)
+* [`ast_types.hpp`](../base/components/ast_types.hpp)
+* [`code_types.hpp`](../base/components/code_types.hpp)
 
-* [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)
-* [AST-Code Object Redesign.#38](https://github.com/Ed94/gencpp/issues/38)
-* [Code-AST Documentation#40](https://github.com/Ed94/gencpp/issues/40)
-* [AST::debug_str() improvements#33](https://github.com/Ed94/gencpp/issues/33)
-* [AST::is_equal implemented and works with singleheader-test#31](https://github.com/Ed94/gencpp/issues/31)
-* [Parser : Add ability to have a parse failure and continue with errors recorded.#35](https://github.com/Ed94/gencpp/issues/35)
-* [Scanner : Add CodeFile#29](https://github.com/Ed94/gencpp/issues/29)
-* [Auxiliary : AST visual debugger#36](https://github.com/Ed94/gencpp/issues/36)
+The C/C++ interface procedures are located with `ast.hpp` (for the Code type), and `code_types.hpp` for all others.
 
+## Serialization
+
+All code types can either serialize using a function of the pattern:
+
+```c
+StrBuilder <prefix>_to_strbuilder(Code code);
+// or
+<prefix>_to_strbuilder(Code code, StrBuilder& result);
+```
+
+Where the first generates strings allocated using Allocator_StringArena and the other appends an existing strings with their backed allocator.
+
+Serialization of for the AST is defined for `Code` in [`ast.cpp`](../base/components/ast.cpp) with `code_to_strbuilder_ref` & `code_to_strbuilder`.  
+Serializtion for the rest of the code types is within [`code_serialization.cpp`](../base/components/code_serialization.cpp).  
+
+Gencpp's serialization does not provide coherent formatting of the code. The user should use a formatter after serializing.

-The lexing and parsing takes shortcuts from whats expected in the standard.
+Macros used within a file should be registered by the user before parsing. This can be done two ways:
 
+1. The register macro interface within [interface.hpp](../base/components/interface.hpp).
+2. Using `def_define` to create a CodeDefine and making sure to not set `opts.dont_register_to_preprocess_macros` to `true`.
+
+## Registering macros
+
+While the registeration of macros in the meta-program's side for parsing can be considered tedius, its necessary for the parser to accurately resolve the macros intent in one pass (and it provides some hygenics by verifying that they are used as intended).
+
+The following can be used to register a macro:
+
+```c
+GEN_API void register_macro( Macro macro );
+GEN_API void register_macros( s32 num, ... );
+GEN_API void register_macros_arr( s32 num, Macro* macros );
+```
+
+The Macro typename is defined with the following in [parser_types.hpp](../base/components/parser_types.hpp):
+
+```c
+struct Macro
+{
+    StrCached  Name;
+    MacroType  Type;
+    MacroFlags Flags;
+};
+```
+
+The macro can be designated one of the following types:
+
+* `MT_Expression`: Intended to resolve to an expression expansion.
+* `MT_Statement`: Intended to resolve an statement expansion.
+* `MT_Typename`: Intended to resolve to a typename.
+
+Additioonally tthe following flags may be set:
+
+* `MF_Functional`: The macro intended to be passed arguments are at least have the calling `()` as part of its usage.
+* `MF_Expects_Body`: The parser should expect a braced-body `{ ... }` after the macro signature `<name> <params>`
+* `MF_Allow_As_Identifier`: Will allow the macro to be an acceptable token/s when an `Tok_Identifier` is expected.
+* `MF_Allow_As_Attribute`: Will allow the macro to be an acceptable token/s when an attribute token/s is expected.
+* `MF_Allow_As_Definition`: Will allow the macro be an acceptable token/s when the parser expects a declartion or definition to resolve after attributes or specifiers have been identified beforehand.
+  * This flag requires that the macro is of type `MT_Statement` to make any sense of usage.
+
+If a macro is not defined the following warning will be issued if `GEN_BUILD_DEBUG=1` during lexing within [lexer.cpp](../base/components/lexer.cpp) - `lex_preprocessor_define`:
+
+```c
+log_fmt("Warning: '%S' was not registered before the lexer processed its #define directive, it will be registered as a expression macro\n"
+    , name.Text 
+);
+```
+
+Further within the same scope, the lexer will issue a warning if it detects a macro was not flagged as function but has an open parenthesis `(` token right after is name with no whitespace:
+
+```c
+log_fmt("Warning: %S registered macro is not flagged as functional yet the definition detects opening parenthesis '(' for arguments\n"
+    , name.Text
+);
+```
+
+Macros are tracked using a `MacroTable Macros;` defined as a member of the library's `Context`.
+
+```c
+typedef HashTable(Macro) MacroTable;
+```
+
+## Notes
+
+* Empty lines used throughout the file are preserved for formatting purposes during ast serialization (they have a dedicated Token: `Tok_NewLine`).
 * 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.
+* The parse API treats any execution scope definitions with no validation and are turned into untyped Code ASTs. (There is a [todo](https://github.com/Ed94/gencpp/issues/49) to add support)
   * *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)
+  * This is useful for example: parsing Unreal `Module_API` macros.

-* Exceptions

+### Feature Macros
+
+* `GEN_DEFINE_ATTRIBUTE_TOKENS` : Allows user to define their own attribute macros for use in parsing.
+  * This can be generated using base.cpp.
+* `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_DONT_ALLOW_INVALID_CODE` (Not implemented yet) : Will fail when an invalid code is constructed, parsed, or serialized.
+* `GEN_C_LIKE_CPP` : Setting to `<true or 1>` Will prevent usage of function defnitions using references and structs with member functions. Structs will still have user-defined operator conversions, for-range support, and other operator overloads
 
 ### The Data & Interface
 
+The library's persistent state is managed tracked by a context struct: `global Context* _ctx;` defined within [static_data.cpp](../base/components/static_data.cpp)
+
+https://github.com/Ed94/gencpp/blob/967a044637f1615c709cb723dc61118fcc08dcdb/base/components/interface.hpp#L39-L97
+
+The interface for the context:
+
+* `init`: Initializtion
+* `deinit`: De-initialization.
+* `reset`: Clears the allocations, but doesn't free the memoery, then calls `init()` on `_ctx` again.
+* `get_context`: Retreive the currently tracked context.
+* `set_context`: Swap out the current tracked context.
+
+
+#### Allocato usage
+
+* `Allocator_DyanmicContainers`: Growing arrays, hash tables. (Unbounded sized containers)
+* `Allocator_Pool`: Fixed-sized object allocations (ASTs, etc)
+* `Allocator_StrCache`: StrCached allocations
+* `Allocator_Temp`: Temporary alloations mostly intended for StrBuilder usage. Manually cleared by the user by their own discretion.
+
+The allocator definitions used are exposed to the user incase they want to dictate memory usage
+
+* Allocators are defined with the `AllocatorInfo` structure found in [`memory.hpp`](../base/dependencies/memory.hpp)
+* Most of the work is just defining the allocation procedure:
+
+```cpp
+    void* ( void* allocator_data, AllocType type, ssize size, ssize alignment, void* old_memory, ssize old_size, u64 flags );
+```
+
+For any allocator above that the user does not define before `init`, a fallback allocator will be assigned that utiizes the `fallback_allocator_proc` wtihin [interface.cpp](../base/components/interface.cpp).
+
 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 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:

+# C Library Generation
+
+`c_library.cpp` generates both *segemnted* and *singleheader* variants of the library compliant with C11.
+
+The output will be in the `gen_segmented/gen` directory (if the directory does not exist, it will create it).
+
+If using the library's provided build scripts:
+
+```ps1
+.\build.ps1 <compiler> <debug or omit> c_lib
+```
+
+To generate a static or dynamic library:
+
+```ps1
+.\build.ps1 <compiler> <debug or omit> c_lib_static c_lib_dyn
+```
+.
+All free from tag identifiers will be prefixed with `gen_` or `GEN_` as the namespace. This can either be changed after generation with a `.refactor` script (or your preferred subst method), OR by modifying [c_library.refactor](./c_library.refactor).
+
+**If c_library.refactor is modified you may need to modify c_library.cpp and its [components](./components/). As some of the container generation relies on that prefix.**
+
+## Generation structure
+
+1. Files are scanned in or parsed.
+    * If they are parsed, its due to requiring some changes to either naming, or adding additonal definitions (container generation, typedefs, etc).
+2. All scanned or parsed code is refactored (identifiers substs) and/or formatted.
+3. Singleheader generated.
+4. Segmented headers and source generated.
+
+## Templated container generation
+
+The array and hashtable containers used across this library are generated using the following implementatioon:
+
+* [containers.array.hpp](./components/containers.array.hpp)
+* [containers.hashtable.hpp](./components/containers.hashtable.hpp)
+
+These are functionally (and interface wise) equivalent to the library's `Array<Type>` `HashTable<Type>` within [containers.hpp](../base/dependencies/containers.hpp)
+
+Both files follow the same pattern of providing three procedures:
+
+* `gen_<container>_base` : Intended to be called once, defines universal "base" definitions.
+* `gen_<container>` : Called per instatiation of the container for a given set of dependent args.
+* `gen_<container>_generic_selection_interface` : Intended to be called once after all of the instantiated containers have finished generating. It will generate a set of generic selection macros as described by Macro Usage section below.
+
+A simple `<container>_DefinitionCounter` is used to know how many instantiations of the template have occured. This is used to determine how to define `GENERIC_SLOT_<ID>_<functionID>` for the generic interface along with how many slots the `_Generic` macro will need to have generated.
+
+## Macro Usage
+
+For the most part macros are kept minimal with exception to `_Generic`...  
+
+The `_Generic` macro plays a key role in reducing direct need of the user to wrangle with mangled definition identifiers of 'templated' containers or for type coercion to map distinct data types to a common code path.
+
+Many C11 libraries don't use it.. and, of those that do. they usually end up obfuscate it with excessive preprocessor abuse; Effort was put into minimizing how much of these macros are handled by the preprocessor vs gencpp itself.
+
+*(I will be explaining this thing for the rest of this seciton along with gencpp c library's usage of it)*
+
+
+The usual presentation (done bare) is the following:
+
+```c
+#define macro_that_selects_typeof_arg(arg, y) \
+_Generic( (arg),                              \
+    int            : some expression,         \
+    double         : some other expression,   \
+    struct Whatnot : something else again,    \
+    default        : fallback expression      \
+)
+```
+
+Where `_Generic` can be considered the follwoing (psuedo-C):
+
+```c
+#define type_expr_pair(type, expr) type: expr
+
+C_Expression _Generic( selector_arg, a_type_expr_pair, ... ) {
+    switch( typeof(selector_arg)) {
+        case a_type_expr_pair:
+            return a_type_expr_pari.expr;
+        ...
+        default:
+            return default.expr;
+    }
+}
+```
+
+The first `arg` of _Generic behaves as the "controlling expression" or the expression that resolves to a type which will dictate which of the following expressions provided after to `_Generic` will be resolved as the one used inline for the implemenation.
+
+
+For this library's purposes we'll be using the functional macro equivalent *(if there is an exception I'll link it at the end of this section)*:
+
+```c
+#define macro_that_uses_selector_arg_for_resolving_a_fucntion( selecting_exp) \
+_Generic( (selecting_exp),                                                    \
+    int            : func_use_int,                                            \
+    double         : func_use_double,                                         \
+    struct Whatnot : func_use_Whatnot,                                        \
+    default        : struct SIGNALS_FAILURE                                   \
+) (selecting_exp)
+```
+
+In this case, we directly added `(selecting_exp)` to the end there.. as we want to directly have the macro resolve to calling a resolved procedure. A default has been set to a struct as that leads to a neat compiler message that would otherwise be impossible beause static_assert is a statement and thus cannot be used within a slot.
+
+Now, even with gencpp generating this type-expression table, we still need wrapper macros to achieve function 'overloading' for the templated containers as _Generic has a [significant drawback](https://www.chiark.greenend.org.uk/~sgtatham/quasiblog/c11-generic/):  
+
+> Discarded expressions still have to be semantically valid.
+
+The only way to absolve this issue [(without resorting to nasty preprocessor hacks)](https://github.com/JacksonAllan/CC/blob/main/articles/Better_C_Generics_Part_1_The_Extendible_Generic.md) is with wrapping expressions in 'slot' resolving macros that do not expand if the slot is not defined:
+
+```c
+GEN_IF_MACRO_DEFINED_INCLUDE_THIS_SLOT( GENERIC_SLOT_1__function_sig )
+```
+
+`GENERIC_SLOT_1__function_sig` is our warpper of a "`int, func_use_int`" pair. The `GEN_IF_MACRO_DEFINED_INCLUDE_THIS_SLOT` is a verbse named macro to indicate that that pair will be expanded ***ONLY IF*** its defined.
+
+So for any given templated container interface. Expect the follwoing (taken straight from generation, and just cleaned up formatting):
+
+```c
+#define gen_array_append( selector_arg, ... ) _Generic(                         \
+(selector_arg ),                                                                \
+    GEN_IF_MACRO_DEFINED_INCLUDE_THIS_SLOT( GEN_GENERIC_SLOT_1__array_append )  \
+    GEN_IF_MACRO_DEFINED_INCLUDE_THIS_SLOT( GEN_GENERIC_SLOT_2__array_append )  \

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