Module: Mailmate::CLI::Search Private

Extended by:
Search
Included in:
Search
Defined in:
lib/mailmate/cli/search.rb

Overview

This module is part of a private API. You should avoid using this module if possible, as it may be removed or be changed in the future.

‘mmsearch` — search MailMate’s ‘.eml` files using a subset of MailMate’s quicksearch syntax. Output is CSV with optional column-aligned padding.

Ported from the standalone mailmate-search script. See ‘~/.claude/skills/email/SKILL.md` for usage examples and the search-string syntax reference.

Sorts ‘rows` in place by the message’s absolute send instant (UTC), so senders in different timezones still order correctly. The first column is always ‘id` (forced in `run`), which lets us hit the `#date` index without re-reading any .eml.
