otter-tools-core shares data processing between small tools and larger applications. Import otter_tools_core.<module>; there is no root barrel. Pure helpers include calculator parsing, durations, calendars, emoji lookup, color conversion, recorder selection, and palette generation. Environment/file/socket operations take explicit std.Env or std.Io. Owned results use String and List; bounded results use standard otr containers. Socket replies append into caller-owned reusable strings rather than returning a 256 KiB inline reply object.

Separate packages

  • otter_tools_search_engine: indexing, query parsing, scanning, fuzzy/content search.
  • otter_tools_search: configured search integration.
  • otter_ocr: OCR integration.
  • otter_tools_core_lua: selected otter.tools.* modules.
Lua exposure is selective. The weather binding parses bodies and reads caches; it does not fetch forecasts by itself. Search daemon operations require desktop-search.
