## Introduction

&ensp; This library contains implementations of headers and classes related to processing  
languages. This includes; ascii/utf8/utf16 string processing, file formats, machine language,  
and programming languages.

&ensp; fennec should be able to process documentation in files, the main ways it will support  
this is through Doxygen and LaTeX. Consider including binaries with releases.


## String Analysis (`langproc/strings`)

&ensp; fennec reimplements the C++ Strings Library as a submodule of this library. This  
is because C++ `std::string` has a lot of overhead. I would say that `std::string`  
is a Jeep, while `fennec::string` is an F2 Car, if that analogy makes any sense. i.e.  
`std::string` offers a lot of use cases, but is slower, while an F2 Car is barebones and  
highly performant on the right surface.

### Implementation

| Symbol   | Implemented | Passed |
|:---------|:-----------:|:------:|
| cstring  |      ✔      |   ✔    |
| string   |      ✔      |   ✔    |
| wcstring |      ✔      |   ✔    |
| wstring  |      ✔      |   ✔    |



## File System (`filesystem`)

&ensp; fennec *does not* reimplement the C++ I/O Library. What it does do  
is create C++ classes that handle file streams, directory streams, and file paths.

### Implementation

| Symbol    | Implemented | Passed |
|:----------|:-----------:|:------:|
| path      |      ✔      |   ✔    |
| file      |      ✔      |   ✔    |
| directory |      ❌      |   ❌    |



## Interpreter (`langproc/parse`)

&ensp; This submodule will contain classes for parsing data. We will need to be 
able to do the following things to achieve support for files that adhere to a 
certain specification. Here are some concepts that will need to be implemented as classes:


### Reading

 - Tokenization
   - Useful for text-based formats
 - Data Parser
   - Useful for binary-based formats
 - Lexical Analysis
   - Necessary for Syntax Coloring
 - Syntax Analysis
   - Necessary for Syntax Coloring
 - Semantic Analysis
   - Necessary for Code Completion
 - Intermediate Code Generation
   - Necessary for any custom programming language in fennec
 - Target Code Generation / Optimization?
   - Necessary for any custom programming language that needs to compile to binary


### Writing

&ensp; The writers will be responsible for writing data as a specific format. I.E. converting  
data values (e.g. floats, ints, etc.) to a readable language (e.g. ascii/utf8/utf16).

 - Writer
 - Binary Writer



## Formats (`langproc/formats`)

&ensp; This submodule will contain classes for processing a variety of file formats.

#### 3D Model Formats

&ensp; unfortunately, most formats are esoteric due to copyright/trademark/etc.  
I will be using assimp for the time being, below is a list of formats supported  
by assimp.
