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.

UnderlyingTypeMacro is a macro the library natively supports: `enum_underlying(type)` that is meant to behave as a wrapper for underlying type assignment.
|
||||
The `enum_underlying_sig` is a `StrC` global var that can be set which will be defined within `PreprocessorDefines` and used in `parser_parse_enum` to identify a valid macro.

You can think of this parser as *frontend parser* vs a *semantic parser*. Its intuitively similar to WYSIWYG. What you ***precerive*** as the syntax from the user-side before the compiler gets a hold of it, is what you get.

* The purpose is to scan or parse files
|

* Some with two basic functions to convert a fil to code: `scan_file` and `parse_file`
|
||||
* `scan_file`: Merely grabs the file and stores it in an untyped Code.
|
||||
* `parse_file`: Will parse the file using `parse_global_body` and return a `CodeBody`.
|

* Two basic functions for grabbing columns from a CSV: `parse_csv_one_column` and `parse_csv_two_columns`
