Stampede

Stampede is in a very early state and may drastically change. It doesn't have releases yet but we try to keep changes in the dev branch until it runs and passes tests.

Stampede is a chat bot backend meant to serve multiple servers and services simultaneously, choosing its response between multiple competing plugins to give the most relevant response. It focuses on supporting a conversational style, and can use LLMs, but will prefer to answer using human-made code. (Wikipedia, Q&A databases, etc)

It is a sequel to the Stampy Discord bot.

Use

Download the Nix package manager. This handles the development environment for Stampede. It runs on Linux, Mac, Windows, and Docker. It won't disrupt your system setup -- though once you start using it, it may be hard to stop. 😄

Once Nix is ready, just cd to the dev directory and run nix develop .# to load the dev environment, then mix deps.get to get the dependencies. Some commands:

• iex -S mix to run Stampede in the dev environment, also providing the famous Elixir interactive shell.
• mix test to run tests
• mix dialyzer to typecheck
• mix credo to simulate a senior engineer nitpicking

Configurations for servers are written in YAML and left in ./Sites/. In different environments (such as test and dev) it will read configs from ./Sites_{environment-name}. Check the service documentation for what options your service has available.

• ./lib/services defines services where chat requests are incoming. They follow the standard set in ./lib/service.ex
• ./lib/plugins defines plugins which suggest potential responses, along with a confidence estimate for how relevant the response would be. Plugins which use resources or take time will offer a callback instead, which will only be called if no other plugins have higher confidence. They follow the standard set in ./lib/plugin.ex

Updating .dialyzer_ignore.exs

Often when changing code, you will end up with superfluous Dialyzer warnings. You can suppress them by updating the Dialyzer ignore file. To start:

rm ./.dialyzer_ignore.exs
mix dialyzer --format ignore_file_strict &> .dialyzer_ignore.exs.incoming

Remove all but the Elixir tuples, which will look like this:

{"lib/stampede.ex", "Function server_id/0 has no local return."},

Put a [ at the start of the file and a ] at the end, so they become one list of tuples. Now you can rename the file to its true name and format it:

mv ./.dialyzer_ignore.exs{.incoming,}
mix format ./.dialyzer_ignore.exs

Now Dialyzer should not raise any more warnings.
