Overview
A basic block containing constituent objects, either blocks or strings.
Constant Summary
- BLOCK_MIN_LENGTH =
80
Instance Attribute Summary collapse
- #indent ⇒ Object readonly
Instance Method Summary collapse
-
#formatted ⇒ String
Format block.
-
#initialize(obj, indent) ⇒ Block
constructor
A new instance of Block.
-
#length ⇒ Integer
Agregate length over each element accounting for spaces.
-
#sxp? ⇒ Boolean
Determins if this block is an SXP, or not.
-
#to_sxp ⇒ String
Turn block into a string in S-expression form This should only be called on a block when no indentation is to be applied.
