📖 Usage Examples

Interactive REPL 

pyr

The REPL provides a rich interactive experience: 

> help me write a Python function to sort a list
> !tools # List available tools
> !models # Show current model info
> !config # Show configuration
> !exit # Exit REPL

AI Provider Examples 

# Use OpenAI
pyr --provider openai --model gpt-4o-mini "explain async/await"

# Use Claude
pyr --provider anthropic --model claude-3-5-haiku-20241022 "review this code"

# Use Ollama (local)
pyr --provider ollama --model qwen2.5:3b "help with debugging"

# Use Grok
pyr --provider grok --model grok-2 "write unit tests"

Context and File Integration 

# Load context from file
pyr --context project-context.txt "analyze the architecture"

# Include Python files
pyr --py main.py --py utils.py "find potential bugs"

# Multiple contexts
pyr --context context1.txt --context context2.txt "compare approaches"

Tool Integration Examples

The AI can automatically use tools when enabled:

  • File Operations : Read/write files, create directories, glob patterns
  • Terminal Commands : Execute shell commands safely
  • Web Search : Search for information and news
  • Database Operations : Store/retrieve key-value data
  • Python Execution : Run Python code snippets
  • Code Search : Search through indexed source code

Example conversation: 

> Create a new Python file called hello.py with a greeting function

AI will use the write_file tool to create the file with proper content.

> Search for recent news about Python

AI will use the web_search_news tool to find current Python news.

> Execute this Python code: print("Hello from PYR!")

AI will use the python_execute tool to run the code and show output.
