lmml - a format to store conversations with agents

lmml is the elixir library to handle the markup language for talking to LLMs, designed as a strict superset of Markdown: any bare .md/text file already parses and means something sensible as an lmml narrative.

During my work on CLI harness, I instantly hit the ceiling storing conversations in any existing format. I obviously needed a container, like OpenOffice does. Having conversations to reference external files is silly in many ways, I needed somewhat one can send by email to a friend, or store in the version control system.

That’s how lmml was born. It’s built upon markdown narrative, but allows extensions. The example of such an extension might be a built-in in-place container for another markup, like settings.yml below.

It works for me way better than all the jsonish kludges used by anthropic/g.
