llama Command Line Interface

This section covers utilities available at the command line through the llama command-line interface (CLI). All major commands are accessed recursively through llama and correspond to packages in the llama library with the same names: for example, llama run is the command you would use to start up the main LLAMA analysis daemon, and it corresponds to the functionality defined in the llama.run module. Read through the subcommands (including llama run as well as others exposing different functionality) to learn how to use LLAMA to it’s fullest from the command line.

A unified interface for accessing LLAMA functionality. Call the available sub-commands to see their capabilities; for example, to list the file-related commands available, run llama files --help; to see available event listeners, run llama listen --help, and to activate the GCN Notice listener, run llama listen gcn.

By default, all warnings about missing optional feature warnings (specified using llama.classes.OptionalFeatureWarning) are supressed. If you’d like to see which features are missing, set LLAMA_OPTIONAL_FEATURE_WARNINGS=true when calling this script. This will inform you of which features are missing and which workarounds are active based on the limitations of your LLAMA installation, but for most everyday work, these warnings are excessive and useless.

Show warnings about optional LLAMA features that may not work on your current installation:

LLAMA_OPTIONAL_FEATURE_WARNINGS=true llama -h

usage: llama [-V] [-h]
             [{batch,com,dev,event,files,flags,install,listen,poll,run,serve}]
             [subargs [subargs ...]]
