Module: Codeball::Border

Defined in:
lib/codeball/border.rb

Overview

Domain knowledge about the visual delimiter between sections in a codeball.

Borders are repeated punctuation patterns that separate entries in serialized codeball text. The pattern is fixed, not configurable.

During serialization, SEPARATOR is used as-is. During parsing, recognition is heuristic to tolerate mangling by browsers, editors, and clipboard transfer.
