Installation
pip install hapax
Basic Usage
1. Define Simple Operations
Operations are the basic building blocks in Hapax. They are pure functions decorated with @ops:
from hapax import ops
from typing import List
@ops # Uses function name as operation name
def tokenize(text: str) -> List[str]:
return text.split()
@ops
def remove_stops(words: List[str]) -> List[str]:
stops = {'the', 'a', 'an'}
return [w for w in words if w not in stops]
2. Compose Operations
Operations can be composed using the >> operator:
# Use >> to chain operations
pipeline = tokenize >> remove_stops
# Use the pipeline
result = pipeline("The quick brown fox") # ['quick', 'brown', 'fox']
3. Create a Graph
For more complex pipelines, you can use the @graph decorator:
from hapax import graph
@graph # Uses function name as graph name
def text_pipeline(text: str) -> List[str]:
return tokenize >> remove_stops
# Use the graph
result = text_pipeline("The quick brown fox")
Add Monitoring (Optional)
import openlit
# Initialize monitoring
openlit.init(otlp_endpoint="http://127.0.0.1:4318")
# Your operations are now automatically monitored!
Next Steps
