+# Pipeline
+
+Interpretation Involves **RUNTIME SEMANTICS**
+
+***THE MEANING OF THE PROGRAM MODEL***
+
+Compliation delegates semantics of runtime behavior to
+***a TARGET language***
+
+Interpetation deals with the semantics itself.
+
+Types of Interpreter **implementation**:
+* AST-based (recursive)
+* Bytecode (Virtual Machines)
+
+Types of Compiler **implementation**:
+* Ahead-of-time (AOT)
+* Just-in-time (JIT)
+
+## Interpeter-AST:
+
+**Translation Stage:**
+1. Program Model
+2. Lexer: Processing into token elements for a parser.
+	* Output : Tokens
+3. Parser: Syntactic Analysis
+	* Output : Abstract Syntax Tree (AST)
+
+**Runtime Stage:**
+4. Interpeter
+5. Runtime Behavior
+
+## Interpreter-Bytecode:
+
+**Translation Stage:**
+1. Program Model
+2. Lexer: Processing into token elements for a parser.
+	* Output : Tokens
+3. Parser: Syntactic Analysis
+	* Output : Abstract Syntax Tree (AST)
+4. Bytecode Emitter
+5. Bytecode instructions primed.
+
+**Runtime Stage:**
+6. Interpreter
+7. Runtime Behavior
+
+
+**Types of Virtual Machine behavior:**
+* Stack based
+	* Stack for operands and operators
+	* Result is always on top of stack
+* Register based
+	* Virtual registers
+	* Result in accumulation register
+	* Map to real via register allocation
+
+## Compiler Ahead-of-Time:
+1. Program Model
+2. Lexer: Processing into token elements for a parser.
+	* Output : Tokens
+3. Parser: Syntactic Analysis
+	* Output : Abstract Syntax Tree (AST)
+4. Code Generator
+5. Intermediate representation primed
+6. Target machine instruction set code generation
+7. Target machine is intended interpretation platform.
+8. Runtime Behavior.
+
+
+## Compiler with LLVM platform:
+1. Program Model
+2. Lexer: Processing into token elements for a parser.
+	* Output : Tokens
+3. Parser: Syntactic Analysis
+	* Output : Abstract Syntax Tree (AST)
+4. LLVM IR generator
+5. LLVM Native code generator
+6. Target machine is intended interpretation platform
+7. Runtime Behavior.
+
+
+Lexer, and parser are considered **FRONT-END**.  
+Code Generation or byte-code gen or interpreter ast impelementation gen
+for target instruction platform is considered **BACK-END**.
+
+
+## Jit Compiler:
+1. Program Model
+2. Lexer: Processing into token elements for a parser.
+	* Output : Tokens
+3. Parser: Syntactic Analysis
+	* Output : Abstract Syntax Tree (AST)
+4. Bytecode Emitter
+5. Bytecode fed to interpeter
+6. Interetor may code gen immediately to target hardware platform or interpret ast directly.
+7. Runtime Behavior.
+
+## Transpiler:
+1. Program Model in input langauge
+2. Lexer: Processing into token elements for a parser.
+	* Output : Tokens
+3. Parser: Syntactic Analysis
+	* Output : Abstract Syntax Tree (AST)
+4. AST Transformation to target AST
+5. Code generation
+6. Program Model in output langauge

+# Eva Programming Langauge
+
+Dynamic programming langauge.
+
+Simple syntax, functional heart, OOP support.
+
+## Eva Expressions:
+```
+(<type> <op1> <op2> ... <opN>)
+```
+
+Example:
+```
+(+ 5 10)
+(set x 15)
+
+(if (> x 10)
+	(print "ok")
+	(print "error")
+)
+```
+
+```
+(def foo (bar)
+	(+ bar 10)
+)
+```
+
+```
+(lambda (x) (* x x) 10)
+```
+
+## Design Goals
+
+* Simple syntax: S-Expression
+* Everything is an expression
+* No explicit return, last evalulated expression is the result
+* First class functions
+* Static scope: all functions are closures
+* Lambda functions
+* Funcitonal programming
+* Imperative programming
+* Namespaces and modules
+* OOP: Class or prototype based.

+## Scripts
+
+Contains some implementation from the lectures but I have no completed it yet...
+
+I made my own context-free version of the language callled "SRegEx"  
+This is mainly what I wanted at the end of the day...
+
+Currently the script only translates to RegEx,  
+I still need to make RegEx to SRegEx
