📖 What is TechScript?

TechScript is a general-purpose, human-first programming language designed to eliminate the syntax clutter of traditional coding. Instead of curly braces, semicolons, and cryptic operator symbols, TechScript uses a clean, keyword-based English grammar.

Under the hood, TechScript is built in Rust for safety and speed. It compiles source files into highly optimized bytecode executed on a custom stack-based Virtual Machine (VM) with NaN-boxed values and a tracing garbage collector, or can generate native code via an LLVM backend.

---

⚡ Why Choose It?

• Zero Clutter: Replace symbols like {, }, (, ), ;, &&, and || with clear keywords like do, end, when, else, and, and or.
• Ecosystem Ready: Runs everywhere (Windows, Linux, macOS, Android/Termux) and comes with full LSP support, linting, formatting, and packaging.
• Top Performance: Powered by a custom stack-based VM written in Rust. Features compile-time constant folding and AST simplifications.

---

📦 Key Differentiators

Traditional Languages	TechScript's Answer	Benefit
Syntax clutter ({}, (), ;)	Plain-English block keywords (do/end, when)	Fewer syntax errors and high readability
Bloated build dependency chains	Single toolchain executable (tsc)	Instant setups with formatting & testing
Heavy memory overhead	Lightweight custom NaN-boxed stack VM	High performance and small footprint

---

✒️ Syntax at a Glance

Here is a side-by-side comparison of TechScript 2.0 with JavaScript and Python:

Feature	TechScript	JavaScript	Python
Variable	x = 10	let x = 10;	x = 10
Constant	const PI = 3.14159	const PI = 3.14159;	PI = 3.14159(convention)
Function	do greet(name) send "Hi " + name end	function greet(name) { return "Hi " + name; }	def greet(name): return "Hi " + name
Condition	when x > 5 say "Big" else say "Small" end	if (x > 5) { console.log("Big"); } else { console.log("Small"); }	if x > 5: print("Big") else: print("Small")
For Loop	for x in list say x end	for (let x of list) { console.log(x); }	for x in list: print(x)
Try / Catch	try res = divide(10, 0) catch error say error end	try { let res = divide(10, 0); } catch (error) { console.error(error); }	try: res = divide(10, 0) except Exception as error: print(error)

📐 Architecture Design

The TechScript compiler driver (tsc) processes source files through a strict pipeline:

graph TD
A[Source Code .txs] --> B[Logos-based Lexer]
B --> C[Pratt expression Parser]
C --> D[Abstract Syntax Tree AST]
D --> E[Semantic Analysis & Scope Audit]
E --> F[AST Optimizer & Constant Folder]
F --> G[IR Crate Generation]
G --> H{Execution Target}
H -->|VM Target| I[Bytecode Compiler]
H -->|Native Target| J[LLVM Backend Crate]
I --> K[Bytecode Format .txc]
K --> L[Stack VM & Tracing GC]
J --> M[Standalone Native Executable]

Loading

The tsc driver tokenizes the program, builds an AST, checks lexical scopes and types, runs constant folding, and compiles the result into bytecode for the VM or leverages LLVM to emit native machine code.

📦 Installation

1. 🪟 Windows Setup

1. Go to the Releases page on GitHub.
2. Download TechScript_Setup.exe (or TechScript_Portable.zip for a zero-install portable version).
3. Run the installer to configure your environment:
   • Installs the native compiler (tsc) and VM.
   • Automatically adds tsc to your system environment PATH.
   • Configures file associations for .txs scripts.

2. 🐧 Linux / 🍎 macOS Setup (Shell Script)

curl -fsSL https://raw.githubusercontent.com/Tcode-Motion/techscript/main/scripts/install.sh | bash

3. 🤖 Android (Termux) Setup

Recommended Method (Shell script):

pkg update
pkg install curl
curl -fsSL https://raw.githubusercontent.com/Tcode-Motion/techscript/main/scripts/install.sh | bash

Alternative Method (pip — Not Recommended):

pkg update
pkg install python
pip install techscript
techscript install

(Note: Python installations in Termux may require the --break-system-packages flag under PEP 668).

4. 🐍 Via pip (All Platforms - Not Recommended)

pip install techscript # or: pip install techscript-lang
techscript install

The PyPI package auto-detects your OS/architecture and downloads the correct native binary from GitHub Releases.

Homebrew (brew install techscript), Winget, and Scoop support coming soon!

---

🚀 Quick Start

Once TechScript is installed, you can write and execute your first script in under 10 seconds:

1. Create and Enter a Project Directory:

   mkdir hello_world
   cd hello_world

2. Create a Script File: Create a new file named hello.txs and add:

   say "Hello, World! 🌍"
   

3. Compile and Run: Run the file using the tsc compiler driver:

   tsc run hello.txs

---

📘 Language Guide

TechScript's syntax builds from simple assignments to full structured programs:

1. Variables: Assigned dynamically. No variable keywords required.

   message = "Hello TechScript"
   

2. Conditionals: Expressed via when/else blocks.

   when status == "active"
   say "Running"
   end
   

3. Loops: Multi-form for ranges or collection iterators.

   for i in 0..5
   say i
   end
   

4. Functions: Declared with do block and returns with send.

   do square(n)
   send n * n
   end
