+
+## Body
+
+These are containers representing a scope body of a definition that can be of the following `ECode` type:
+
+* Class_Body
+* Enum_Body
+* Export_Body
+* Extern_Linkage_Body
+* Function_Body
+* Global_Body
+* Namespace_Body
+* Struct_Body
+* Union_Body
+
+Fields:
+
+```cpp
+Code         Front;
+Code         Back;
+Code         Parent;
+StringCached Name;
+CodeT        Type;
+s32          NumEntries;
+```
+
+The `Front` member represents the start of the link list and `Back` the end.
+NumEntries is the number of entries in the body.
+
+Parent should have a compatible ECode type for the type of defintion used.
+
+Serialization:
+
+Will output only the entries, the braces are handled by the parent.
+
+```cpp
+<Front>...
+<Back>
+```
+
+## Attributes
+
+Represent standard or vendor specific C/C++ attributes.
+
+Fields:
+
+```cpp
+StringCached  Content;
+Code          Prev;
+Code          Next;
+Code          Parent;
+StringCached  Name;
+CodeT         Type;
+```
+
+Serialization:
+
+```cpp
+<Content>
+```
+
+While the parser supports the `__declspec` and `__attribute__` syntax, the upfront constructor ( def_attributes ) must have the user specify the entire attribute, including the `[[]]`, `__declspec` or `__attribute__` parts.
+
+## Comment
+
+Stores a comment.
+
+Fields:
+
+```cpp
+StringCached  Content;
+Code          Prev;
+Code          Next;
+Code          Parent;
+StringCached  Name;
+CodeT         Type;
+```
+
+Serialization:
+
+```cpp
+<Content>
+```
+
+The parser will perserve comments found if residing with a body or in accepted inline-to-definition locations.
+Otherwise they will be skipped by the TokArray::__eat and TokArray::current( skip foramtting enabled ) functions.
+
+The upfront constructor: `def_comment` expects to recieve a comment without the `//` or `/* */` parts. It will add them during construction.
+
+## Class & Struct
+
+Fields:
+
+```cpp

+
+You'll notice that only one parent type is supported only with parent access. This library only supports single inheritance, the rest must be done through interfaces.

+# Parser's Algorithim
+
+gencpp uses a hand-written recursive descent parser. Both the lexer and parser handle a full C/C++ file in a single pass.
+
+## Notable implementation background
+
+### Lexer
+
+The lex procedure does the lexical pass of content provided as a `StrC` type.
+The tokens are stored (for now) in `gen::Parser::Tokens`.
+
+Fields:
+```cpp
+Array<Token> Arr;
+s32          Idx;
+```
+
+
+What token types are supported can be found in [ETokType.csv](../project/enums/ETokType.csv) you can also find the token types in [ETokType.h](../project/components/gen/etoktype.cpp) , which is the generated enum from the csv file.
+
+Tokens are defined with the struct `gen::Parser::Token`:
+
+Fields:
+```cpp
+char const* Text;
+sptr        Length;
+TokType     Type;
+s32         Line;
+s32         Column;
+bool 	    IsAssign;
+```
+
+`IsAssign` is a flag that is set when the token is an assignment operator. Which is used for various purposes:
+
+* Using statment assignment
+* Parameter argument default value assignment
+* Variable declaration initialization assignment
+
+I plan to replace IsAssign with a general flags field and properly keep track of all operator types instead of abstracting it away to `ETokType::Operator`.
+
+Traversing the tokens is done with the following interface macros:
+
+| Macro | Description |
+| --- | --- |
+| `currtok_noskip` | Get the current token without skipping whitespace |
+| `currtok` | Get the current token, skip any whitespace tokens |
+| `prevtok` | Get the previous token (does not skip whitespace) |
+| `nexttok` | Get the next token (does not skip whitespace) |
+| `eat( Token Type )` | Check to see if the current token is of the given type, if so, advance Token's index to the next token |
+| `left` | Get the number of tokens left in the token array |
+| `check_noskip` | Check to see if the current token is of the given type, without skipping whitespace |
+| `check` | Check to see if the current token is of the given type, skip any whitespace tokens |
+
+### Parser
+
+The parser has a limited user interface, only specific types of definitions or statements are expected to be provided by the user directly when using to construct an AST dynamically (See SOA for example). It however does attempt to provide capability to parse a full C/C++ from production codebases. 
+
+Each public user interface procedure has the following format:
+
+```cpp
+CodeStruct parse_<definition type>( StrC def )
+{
+    check_parse_args( def );
+    using namespace Parser;
+
+    TokArray toks = lex( def );
+    if ( toks.Arr == nullptr )
+        return CodeInvalid;
+
+    // Parse the tokens and return a constructed AST using internal procedures
+    ...
+}
+```
+
+The most top-level parsing procedure used for C/C++ file parsing is `parse_global_body`:
+
+It uses a helper procedure called `parse_global_nspace`.
+
+Each internal procedure will be 
+
+## parse_global_nspace
+
+1. Make sure the type provided to the helper function is a `Namespace_Body`, `Global_Body`, `Export_Body`, `Extern_Linkage_body`.
+2. If its not a `Global_Body` eat the opening brace for the scope.
+3.

+
+Will test the following modules + plugins:

+* Kismet
+* Slate
+* RTTI Bases
+* Gameframework
+* Actor & Component Bases
+* Lyra
+
+In the future I could attempt to do a similar test to that of the godot engine full compilation test.
+
+For now it just does the following:
+
+* Download the Unreal source code
+* For each module
+    1. Grab all header and source file paths
+    2. Generate an ast for each file and serialize it to a file called `<name of file>.gen.<h/c>`
+    3. Reconstruct the ast from the generated file
+    4. Compare the original ast to the reconstructed ast
+
+This wil most likely be the most difficult test along-side godot's full compilation test.
