CodeCraft - Intelligent Python Editor

An intelligent coding assistant built in Rust that analyzes Python code in real-time using tree-sitter and provides instant code quality improvements.

Features

Real-Time Code Analysis

• Tree-sitter powered parsing: Uses the official Python tree-sitter grammar for accurate syntax analysis
• Live diagnostics: Instant feedback as you type
• Smart pattern detection: Identifies anti-patterns and security issues

Intelligent Suggestions

CodeCraft detects and helps fix:

1. Bare except clauses - Catches dangerous except: that can hide critical errors

   • Auto-fix: Converts to except Exception:

2. Mutable default arguments - Warns about lists/dicts as default parameters

3. Old string formatting - Suggests using f-strings over .format()

4. List comprehension opportunities - Identifies loops that append to lists

5. Deprecated imports - Flags old modules (imp, optparse)

6. Inefficient loops - Suggests enumerate() over range(len())

7. Security issues - Detects dangerous functions (eval, exec, compile)

One-Click Code Actions

When CodeCraft identifies an issue with an available fix, click the "🔧 Apply Fix" button to automatically refactor your code!

Python Code Execution

• Run code directly from the editor (Ctrl+R)
• Automatic dependency detection - Extracts imports and installs missing packages
• Real-time output - See stdout and stderr as your code runs
• Smart dependency management - Skips standard library modules

Requirements

• Rust 1.70+ (for building)
• Python 3.x (for running code)
• pip (for installing dependencies)

Installation

git clone <your-repo>
cd text_edit
cargo build --release

Usage

Run the application:

cargo run --release

Keyboard Shortcuts

• Ctrl+N: New file
• Ctrl+O: Open file
• Ctrl+S: Save file
• Ctrl+R: Run Python code

UI Components

1. Editor Panel (center): Write your Python code with line numbers and issue indicators
2. Diagnostics Panel (left): View all detected issues with descriptions and quick fixes
3. Output Panel (bottom): See execution results and dependency installation logs

Example

When you write code like this:

def example_function():
    try:
        result = []
        for i in range(len([1, 2, 3])):
            result.append(i * 2)
        return result
    except:
        pass

CodeCraft will detect:

• Bare except: clause (with one-click fix)
• Inefficient range(len()) pattern
• List comprehension opportunity

Architecture

• analyzer.rs: Tree-sitter integration and Python code analysis
• runner.rs: Python code execution with dependency management
• main.rs: egui-based UI and application logic

Dependencies

• eframe/egui: Modern immediate-mode GUI framework
• tree-sitter: Incremental parsing system
• tree-sitter-python: Python grammar for tree-sitter
• regex: Pattern matching for import detection
• rfd: Native file dialogs

Future Enhancements

• More code actions (convert to f-string, refactor to comprehension)
• Custom rule configuration
• Support for other languages
• LSP integration
• Inline code suggestions with ghost text
