Module: PrettyPrint::Buffer

Defined in:
lib/syntax_tree/prettyprint.rb

Overview

When building up the contents in the output buffer, it’s convenient to be able to trim trailing whitespace before newlines. If the output object is a string or array or strings, then we can do this with some gsub calls. If not, then this effectively just wraps the output object and forwards on calls to <<.

Defined Under Namespace

Classes: ArrayBuffer, DefaultBuffer, StringBuffer
