Class: SXP::Generator::Block
- Defined in:
- vendor/bundler/ruby/3.3.0/bundler/gems/sxp.rb-7a771a32c5fe/lib/sxp/generator.rb
Overview
A basic block containing constituent objects, either blocks or strings.
Constant Summary collapse
- BLOCK_MIN_LENGTH =
80
Instance Attribute Summary collapse
- #indent ⇒ Object readonly
Instance Method Summary collapse
-
#formatted ⇒ String
Format block.
-
#initialize(obj, indent, prefixes: nil, base_uri: nil) ⇒ Block
constructor
A new instance of Block.
-
#length ⇒ Integer
Aggregate length over each element accounting for spaces.
-
#sxp? ⇒ Boolean
Determins if this block is an SXP, or not.
-
#to_sxp(prefixes: nil, base_uri: nil) ⇒ 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.
Constructor Details
#initialize(obj, indent, prefixes: nil, base_uri: nil) ⇒ Block
Returns a new instance of Block.
