 ## Notes
 
-The project has reached an *alpha* state, all the current functionality works for the test cases but it will most likely break in many other cases.  
+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.
 
-A `natvis` and `natstepfilter` are provided in the scripts directory.
+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.
 
-***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...
+A `natvis` and `natstepfilter` are provided in the scripts directory (its outdated, I'll update this readme when its not).  
+*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.
+`gen.cpp` \`s  `main()` is defined as `gen_main()` which the user will have to define once for their program. There they may reflect and/or generate code.

+# 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 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.
+  * **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:
+
+* `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
+* 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.
+
+If using the library's provided build scripts:
+
+```ps1
+.\build.ps1 <compiler> <debug or omit> base
+```
+
+Will refresh those files.
+
+## 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_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).
+
+## 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 (Str) and returns a Str 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", str_for_type,
+		"name", str_for_name,
+	and:
+		stringize( typedef <type> <name> <name>; )
+-----------------------------------------------------------
+So the full call for this example would be:
+	token_fmt(
+		"type", str_for_type
+	,	"name", str_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.

+`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*`.  
+In order to abstract away constant use of `AST*` its wrapped in a Code type which can be either:
+
+When its the [C generated variant of the library](../gen_c_library/)
+```c
+typedef AST* Code;
+tyepdef AST_<name>* Code<name>;
+...
+```
+
+**or**
+
+For C++:
+```cpp
+struct Code {
+    AST* ast;
+};
+struct Code<name> {
+    ...
+
+    AST_<name>* ast;
+};
+```
+
+The full definitions of all asts are within:
+
+* [`ast.hpp`](../base/components/ast.hpp)
+* [`ast_types.hpp`](../base/components/ast_types.hpp)
+* [`code_types.hpp`](../base/components/code_types.hpp)
+
+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.chpp`](../base/components/ast.cpp) with `code_to_strbuilder_ptr` & `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.

+
+## `parse_comment`
+
+1. Just wrap the token into a cached string ( the lexer did the processing )

+
+This is a helper function used by the following functions to help resolve a declaration or definition:
+

+* `parse_global_nspace`
+* `parse_union`
+
+A portion of the code in `parse_typedef` is very similar to this as both have to resolve a similar issue.

+    2. If the token has a closing brace its an inplace definition
+    3. If the `token[-2]` is an identifier & `token[-3]` is the declaration type, its a variable using a namespaced type.

+    6. If any of the above is the case, `parse_operator_function_or_variable`
+4. If the `token[2]` is a vendor fundamental type (builtin) then it is an enum forward declaration.
+5. If the previous token was a closing curly brace, its a definition : `parse_forward_or_definition`

+
+## `parse_define`
+
+1. Define directive
+2. Get identifier

+    3. Decl_Struct : `parse_struct`
+    4. Decl_Union : `parse_union`
+
+## `parse_function_after_name`
+
+This is needed as a function defintion is not easily resolvable early on, as such this function handles resolving a function
+after its been made ceratin that the type of declaration or definition is indeed for a function signature.
+
+By the point this function is called the following are known : export module flag, attributes, specifiers, return type, & name
+
+1. `parse_parameters`
+2. parse postfix specifiers (we do not check if the specifier here is correct or not to be here... yet)
+3. If there is a body : `parse_body`
+4. Otherwise :
+     1. Statment end
+     2. Check for inline comment
+
+## `parse_function_body`
+
+Currently there is no actual parsing of the function body. Any content with the braces is shoved into an execution AST node.
+In the future statements and expressions will be parsed.
+
+1. Open curly brace
+2. Grab all tokens between the brace and the closing brace, shove them in a execution AST node.
+3. Closing curly brace
+
+## `parse_global_nspace`
+
+1. Make sure this is being called for a valid type (namespace, global body, export body, linkage body)
+2. If its not a global body, consume the opening curly brace
+3. Parse the body (Possible options):
+    1. Ignore dangling end statements
+    2. NewLine : ast constant
+    3. Comment : `parse_comment`
+    4. Decl_Cass : `parse_complicated_definition`
+    5. Decl_Enum : `parse_complicated_definition`
+    6. Decl_Extern_Linkage : `parse_extern_link`
+    7. Decl_Namespace : `parse_namespace`
+    8. Decl_Struct : `parse_complicated_definition`
+    9. Decl_Template : `parse_template`
+    10. Decl_Typedef : `parse_typedef`
+    11. Decl_Union : `parse_complicated_definition`
+    12. Decl_Using : `parse_using`
+    13. Preprocess_Define : `parse_define`
+    14. Preprocess_Include : `parse_include`
+    15. Preprocess_If, IfDef, IfNotDef, Elif : `parse_preprocess_cond`
+    16. Preprocess_Else : ast constant
+    17. Preprocess_Endif : ast constant
+    18. Preprocess_Macro : `parse_simple_preprocess`
+    19. Preprocess_Pragma : `parse_pragma`
+    20. Preprocess_Unsupported : `parse_simple_preprocess`
+    21. StaticAssert : `parse_static_assert`
+    22. Module_Export : `parse_export_body`
+    23. Module_Import : NOT_IMPLEMENTED
+    24. The following compound into a resolved definition or declaration:
+        1. Attributes ( Standard, GNU, MSVC, Macro ) : `parse_attributes`
+        2. Specifiers ( consteval, constexpr, constinit, extern, forceinline, global, inline, internal_linkage, neverinline, static )
+        3. Is either ( identifier, const specifier, long, short, signed, unsigned, bool, char, double, int)
+            1. Attempt to parse as construtor or destructor : `parse_global_nspace_constructor_destructor`
+            2. If its an operator cast (definition outside class) : `parse_operator_cast`
+            3. Its an operator, function, or varaible : `parse_operator_function_or_varaible`
+4. If its not a global body, consume the closing curly brace
+
+## `parse_global_nspace_constructor_destructor`
+
+1. Look ahead for the start of the arguments for a possible constructor/destructor
+2. Go back past the identifier
+3. Check to see if its a destructor by checking for the `~`
+4. Continue the next token should be a `::`
+5. Determine if the next valid identifier (ignoring possible template parameters) is the same as the first identifier of the function.
+6. If it is we have either a constructor or destructor so parse using their respective functions (`parse_constructor`, `parse_destructor`).
+
+## `parse_identifier`
+
+This is going to get heavily changed down the line to have a more broken down "identifier expression" so that the qualifier, template args, etc, can be distinguished between the targeted identifier.  
+The function can parse all of them, however the AST node compresses them all into a string.
+
+1. Consume first identifier
+2. `parse_template_args`
+3. While there is a static symbol accessor ( `::` )
+    1. Consume `::`
+    2. Consume member identifier
+    3. `parse_template args` (for member identifier)
+    4. If a `~` is encounted and the scope is for a destructor's identifier, do not consume it and return with what parsed.
+
+## `parse_include`
+
+1. Consume include directive
+2. Consume the path
+
+## `parse_operator_after_ret_type`
+
+This is needed as a operator defintion is not easily resolvable early on, as such this function handles resolving a operator after its been made ceratin that the type of declaration or definition is indeed for a operator signature.
+
+By the point this function is called the following are known : export module flag, attributes, specifiers, return type
+
+1. If there is any qualifiers for the operator, parse them
+2. Consume operator keyword
+3. Determine the operator type (This will be offloaded to the lexer moreso than how it is now) & consume
+4. `parse_params`
+5. If there is no parameters this is operator is a member of pointer if its symbols is a *.
+6. Parse postfix specifiers
+7. If there is a opening curly brace, `parse function_body`
+8. Otherwise: consume end statement, check for inline comment.
+
+## `parse_operator_function_or_variable`
+
+When this function is called, attribute and specifiers may have been resolved, however what comes next can still be either an operator, function, or varaible.
+
+1. Check for preprocessor macro, if there is one : `parse_simple_preprocess`
+2. `parse_type` (Does the bulk of the work)
+3. Begin lookahead to see if we get qualifiers or we eventually find the operator declaration
+4. If we find an operator keyword : `parse_operator_after_ret_type`
+5. otherwise :
+    1. `parse_identifier`
+    2. If we se a opening parenthesis (capture start), its a function : `parse_function_after_name`
+    3. Its a variable : `parse_variable_after_name`
+
+## `parse_pragma`
+
+1. Consume pragma directive
+2. Process the token content into cached string
+
+## `parse_params`
+
+1. Consume either a `(` or `<` based on `use_template_capture` arg
+2. If the we immdiately find a closing token, consume it and finish.
+3. If we encounter a varadic argument, consume it and return a `param_varadic` ast constant
+4. `parse_type`
+5. If we have a macro, parse it (Unreal has macros as tags to parameters and or as entire arguments).
+6. So long as next token isn't a comma
+  a. If we have an identifier
+    1. Consume it
+    2. Check for assignment:
+      a. Consume assign operator
+      b. Parse the expression
+7. While we continue to encounter commas
+    a. Consume them
+    b. Repeat steps 3 to 6.2.b
+8. Consume the closing token
+
+## `parse_preprocess_cond`
+
+1. Parse conditional directive
+2. Process directive's content expression
+
+## `parse_simple_preprocess`
+
+There is still decent room for improvement in this setup. Right now the entire macro's relevant tokens are shoved into an untyped AST. It would be better to store it instead in an `AST_Macro` node instead down the line.
+
+1. Consume the macro token
+2. Check for an opening curly brace
+    1. Consume opening curly brace
+    2. Until the closing curly is encountered consume all tokens.
+    3. If the parent context is a typedef
+        1. Check for end stement
+            1. Consume it
+            2. Consume potential inline comment
+3. Otherwise do steps 3 to 3.1.2
+4. Shove it all in an untyped string
+
+## `parse_static_assert`
+
+1. Consume static assert and opening curly brace
+2. Consume all tokens until the the closing brace is reached.
+3. Consume curly brace and end statement
+4. Place all tokens within braces into a content for the assert.
+
+## `parse_template_args`
+
+This will get changed heavily once we have better support for typename expressions
+
+1. Consume opening angle bracket
+2. Consume all tokens until closing angle bracket
+3. Consme closing angle bracket
+4. Return the currtok with the ammended length.
+
+## `parse_variable_after_name`
+
+This is needed as a variable defintion is not easily resolvable early on, it takes a long evaluation period before its known that the declaration or definition is a variable. As such this function handles resolving a variable.
+
+By the point this function is called the following are known : export module flag, attributes, specifiers, value type, name
+
+1. If its an assignment, parse the assignment expression (currently to an untyped string)
+2. If its an opening curly brace, parse the expression within (currnelty to an untyped stirng).
+    1. Consume the closing curly brace
+3. If its a `:`, we're dealing with bitfield definition:

+    2. Check for inline comment
+
+## `parse_destructor`
+
+1. Check for and consume virtual specifier
+2. Check for the `~` operator
+3. `parse_identifier`
+4. Consume opening and closing parenthesis
+5. Check for assignment operator:
+    1. Consume assignment op
+    2. Consume pure specifier `0`
+6. If not pure virtual & currtok is opening curly brace:
+    1. `parse_function_body`
+7. Otherwise:
+    1. Consume end statement
+    2. If currtok is comment : `parse_comment`
+
+## `parse_enum`

+            2. Consume the expression (assigned to untyped string for now)
+            3. If a macro is encountered consume it (Unreal UMETA macro support)
+        3. If there is a comma, consume it

+This function's implementation is awful and not done correctly. It will most likely be overhauled in the future as I plan to segement the AST_Type into several AST varaints along with sub-types to help produce robust type expressions.  
+Hopefully I won't need to make authentic type expressions as I was hopeing to avoid that...

+Anything that is in the qualifier capture of the function typename is treated as an expression abstracted as an untyped string
+
+1. `parse_attributes`
+2. Parse specifiers
+3. If the `parse_type` was called from a template parse, check to see if class was used instead of typname and consume as name.

+    3. If its a compound native type expression (unsigned, char, short, long, int, float, dobule, etc )
+    4. Ends up being a regular type alias of an identifier
+5. Parse specifiers (postfix)
+6. We need to now look ahead to see If we're dealing with a function typename
+7. If wer're dealing with a function typename:
+    1. Shove the specifiers, and identifier code we have so far into a return type typename's Name (untyped string)

 * Builder
-* Editor
 * Scanner
 
-Editor and Scanner are disabled by default, use `GEN_FEATURE_EDITOR` and `GEN_FEATURE_SCANNER` to enable them.

 * 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
+### Scanner Auxillary Interface
 
-**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.
+* 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`

+
+`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](./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.**
