|
||
## Features
|
||
|
||
### 🚀 Core Language Features
|
||
- **Dynamic typing with type inference** - Strong typing with minimal annotations
|
||
- **Modern control flow** - Full `for` loop support with proper scoping
|
||
- **First-class functions** - Lambda expressions and closures
|
||
- **Rich data structures** - Structs, lists, maps, and tuples
|
||
- **Memory safety** - No null pointer exceptions, automatic memory management
|
||
|
||
### 🔧 Technical Highlights
|
||
- **Three-level scoping for loops** - Proper variable isolation in iterations
|
||
- **Smart semicolon handling** - Flexible statement termination with RAII guards
|
||
- **Comprehensive error handling** - Detailed error messages with source locations
|
||
- **Clean C++ implementation** - Modern C++23 with RAII and smart pointers
|
||
|
||
### 🔧 Install
|
||
# Installation
|
||
|
||
## Prerequisites
|
||
**Xmake** version **3.0.0 or higher** must be installed on your system.
|
||
|
||
## Build Instructions
|
||
|
||
1. Clone the repository:
|
||
|
||
```bash
|
||
git clone https://git.fig-lang.cn/PuqiAR/Fig.git
|
||
# Recommend
|
||
```
|
||
or
|
||
|
||
```bash
|
||
git clone https://github.com/PuqiAR/Fig.git
|
||
```
|
||
|
||
2. Navigate to the project directory:
|
||
|
||
```bash
|
||
cd Fig
|
||
```
|
||
|
||
3. Build the project:
|
||
|
||
```bash
|
||
xmake build Fig
|
||
```
|
||
|
||
4. Run the program:
|
||
|
||
```bash
|
||
xmake run Fig [file]
|
||
```
|
||
|
||
Replace `[file]` with the path to your input file.
|
||
|
||
## Language Philosophy
|
||
Fig is designed around several core principles:
|
||
|
||
Clarity over cleverness - Code should be readable first
|
||
|
||
Safety by default - Prevent common errors at compile time
|
||
|
||
Modern ergonomics - Developer experience matters
|
||
|
||
Gradual learning - Simple to start, powerful when needed
|
||
|
||
## Performance Summary
|
||
|
||
**Version:** 0.4.2-alpha (Tree-walker Interpreter)
|
||
**Test Hardware:** i5-13490F, Windows 11
|
||
|
||
**Execution Times for Fibonacci(30):**
|
||
- Naive Recursion: **11.72s**
|
||
- Memoization: **0.93ms** (12,600× faster)
|
||
- Iteration: **0.37ms** (31,300× faster)
|
||
- Tail Recursion: **0.40ms** (29,200× faster)
|

|
||
**Visual Comparison:**
|
||
```
|
||
Naive Recursion : ████████████████████████████████████████ 11.72s
|
||
Memoization : ▉ 0.93ms
|
||
Iteration : ▍ 0.37ms
|
||
