Module: Card::Lexicon

Defined in:
lib/card/lexicon.rb

Overview

Translates names to ids and vice versa via a cached “lex” representation: name for simple cards, [left_id, right_id] for compound cards.

Note, unlike Card::Fetch, Card::Lexicon:

1. does NOT distinguish between trashed and untrashed cards.
2. does NOT respect local name changes

.rescuing ⇒ Object

this is to address problems whereby renaming errors leave the lexicon broken. NEEDS TESTING
