Module: SyntaxTree::Quotes
- Defined in:
- lib/syntax_tree/node.rb
Overview
Responsible for providing information about quotes to be used for strings and dynamic symbols.
Constant Summary collapse
- PAIRS =
The matching pairs of quotes that can be used with % literals.
{ "(" => ")", "[" => "]", "{" => "}", "<" => ">" }.freeze
Class Method Summary collapse
-
.locked?(node, quote) ⇒ Boolean
If there is some part of this string that matches an escape sequence or that contains the interpolation pattern (“#{”), then we are locked into whichever quote the user chose. (If they chose single quotes, then double quoting would activate the escape sequence, and if they chose double quotes, then single quotes would deactivate it.).
-
.matching(quote) ⇒ Object
Find the matching closing quote for the given opening quote.
-
.normalize(content, enclosing) ⇒ Object
Escape and unescape single and double quotes as needed to be able to enclose
content
