 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.

+## Navigation
+
+# base
+
+[Top](../Readme.md)
+
+* [docs](../docs/Readme.md)
+
+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.
+
+Standard formats:
+
+* **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 other libraries to regenerate or generate the other library formats.
+    * `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.
+    * `misc.hpp`: Misc functionality used by the library generation metaprograms.
+    * `undef.macros.h`: Undefines all macros from library that original were intended to leak into user code.
+  * **auxillary**: 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 funcctions 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_segemented 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 segemented and single-header set of variants are generatd.
+
+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:

+
+## 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
+* Inteniality 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 implementaiton. 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.
+
+## On multi-threading
+
+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_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 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). Extending it is more serious.
+
+## A note on compilation and runtime generation speed
+
+The library is designed to be fast to compile and generate code at runtime as fast as resonable possible on a debug build.
+Its recommended that your metaprogam be compiled using a single translation unit (unity build).

+Takes a format string (char const*) and a list of tokens (StrC) and returns a StrC of the formatted string.
+Tokens are provided in '<'identifier'>' format where '<' '>' are just angle brackets (you can change it in token_fmt_va)
+---------------------------------------------------------
+	Example - A string with:
+		typedef <type> <name> <name>;
+	Will have a token_fmt arguments populated with:
+		"type", strc_for_type,
+		"name", strc_for_name,
+	and:
+		stringize( typedef <type> <name> <name>; )
+-----------------------------------------------------------
+So the full call for this example would be:
+	token_fmt(
+		"type", strc_for_type
+	,	"name", strc_for_name
+	,	stringize(
+		typedef <type> <name> <name>
+	));
+!----------------------------------------------------------
+! Note: token_fmt_va is whitespace sensitive for the tokens.
+! This can be alleviated by skipping whitespace between brackets but it was choosen to not have that implementation by default.

 ## 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.
+When its the [C generated variant of the library](../gen_c_library/)
-
+```c
-The simpliest being just a type alias.
+typedef AST* Code;
-
+tyepdef AST_<name>* Code<name>;
-```cpp
+...
-using Code = AST*;
 ```
 
-This is what the genc library would have to use due to its constraints of a langauge.  
+**or**
-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.
 
+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.  
+The full definitions of all asts are within:
-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:
+* [`ast.hpp`](../base/components/ast.hpp)
+* [`ast_types.hpp`](../base/components/ast_types.hpp)
+* [`code_types.hpp`](../base/components/ast_types.hpp)
 
-* [Improvements Lexer & Token struct#27](https://github.com/Ed94/gencpp/issues/27)
+The C/C++ interface procedures are located with `ast.hpp` (for the Code type), and `code_types.hpp` for all others.

-* [Auxiliary : AST visual debugger#36](https://github.com/Ed94/gencpp/issues/36)
 
+## Serialization
+
+All code types can either serialize using a function of the pattern:
+
+```c
+String <prefix>_to_string(Code code);
+// or
+<prefix>_to_string(Code code, String& 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.chpp`](../base/components/ast.cpp) with `code_to_string_ptr` & `code_to_string`.  
+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.

-* Language provide dynamic dispatch, RTTI
-* Object-Oriented Inheritance

-Two generic templated containers are used throughout the library:

+# 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_library
+```
+
+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.
+
+**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.**
