Module: OmnifocusMcp::Utils::DateFilter

Defined in:
lib/omnifocus_mcp/utils/date_filter.rb

Overview

Parses MCP date-filter wire values and converts them to days-from-today.

Named filters are modeled as symbols (‘:today`, `:tomorrow`, …) after parsing; only string input is accepted at the MCP boundary. Numeric and ISO-date inputs resolve directly to day offsets.
