Command Line Interface

A command line interface named scl is available to interact with SMARTS.

Examples of common usage are as follows.

# Start envision server
$ scl envision start

# Build all scenarios under given directories
$ scl scenario build-all ./scenarios

# Rebuild a single scenario, replacing any existing generated assets
$ scl scenario build --clean scenarios/sumo/loop

# Clean generated scenario artifacts
$ scl scenario clean scenarios/sumo/loop
