Environment variables
Weave provides a set of environment variables to configure and optimize its behavior. You can set these variables in your shell or within scripts to control specific functionality.
# Example of setting environment variables in the shell
WEAVE_PARALLELISM=10 # Controls the number of parallel workers
WEAVE_PRINT_CALL_LINK=false # Disables call link output
# Example of setting environment variables in Python
import os
os.environ["WEAVE_PARALLELISM"] = "10"
