Defined in:

lib/haml_lint/node_transformer.rb

Overview

Responsible for transforming Haml::Parser::ParseNode objects into corresponding Tree::Node objects.

The parse tree generated by HAML has a number of strange cases where certain types of nodes are created that don’t necessarily correspond to what one would expect. This class is intended to isolate and handle these cases so that linters don’t have to deal with them.

Instance Method Summary

• #initialize(document) ⇒ NodeTransformer constructor

  Creates a node transformer for the given Haml document.

• #transform(haml_node) ⇒ HamlLint::Tree::Node

  Converts the given HAML parse node into its corresponding HAML-Lint parse node.

Parameters:

• document (HamlLint::Document)

def initialize(document)
  @document = document
end
