Code2LLM CLI Tool

A utility for generating LLM-friendly context files from codebases with intelligent filtering and structure visualization.

Features

• Recursive directory traversal
• Gitignore-style pattern matching
• File size limits
• Visual directory tree with ignored/size-exceeded annotations
• Markdown output with syntax highlighting
• Context description integration

Installation

pip install pathspec

Usage

python code2llm.py [OPTIONS]

Options

Flag	Description	Default
--target-dir	Directory to process	. (current dir)
--ignore-file	Path to ignore rules file	.context.ignore
--output	Output file path	context.md
--max-size	Maximum file size in bytes	102400 (100KB)
--context-file	Path to optional context description file	None

Example Commands

1. Basic usage:

   python code2llm.py

2. Process specific directory with custom ignore rules:

   python code2llm.py --target-dir ./src --ignore-file .custom-ignore

3. Generate output with 2MB size limit and project description:

   python code2llm.py --max-size 2097152 --context-file project-info.md

.context.ignore Example

# Common ignore patterns*.env*.log*.bin*.hex*.pdf*.jpg*.png*.zip.DS_Store# Directoriesnode_modules/
__pycache__/
.vscode/
dist/
build/

Output Structure

1. Context Overview (optional):
   Contains content from --context-file

2. Codebase Structure:
   Visual directory tree showing all files with ignored/size-exceeded annotations

3. File Contents:
   All included files with syntax-highlighted content

Best Practices

• Use --context-file to provide architectural overview
• Keep generated files under 1MB for chat-based LLMs
• Regularly update .context.ignore as project evolves
• Combine with manual context descriptions for best results
