Class: ExternalArray

Inherits:
ExternalArchive show all
Defined in:
lib/external_array.rb

Overview

– YAML cannot/does not properly handle:

  • Proc

  • Class (cannot dump)

  • Carriage return strings (removes “r”): “r”, “rn”, “string_with_rn_internal”

  • Chains of newlines (loads to “”): “n”, “nn”

Bugs:

@cls[ 'cat', 99, /a/, @cls[ 1, 2, 3] ].include?(@cls[ 1, 2, 3])  raises error
