Class: Puppet::Pops::Parser::Locator::Locator19
- Inherits:
-
AbstractLocator
- Object
- Puppet::Pops::Parser::Locator
- AbstractLocator
- Puppet::Pops::Parser::Locator::Locator19
- Includes:
- Types::PuppetObject
- Defined in:
- lib/puppet/pops/parser/locator.rb
Overview
This implementation is for Ruby19 and Ruby20. It uses byteslice to get strings from byte based offsets. For Ruby20 this is faster than using the Stringscanner.charpos method (byteslice outperforms it, when strings are frozen).

-
#char_length(offset, end_offset) ⇒ Object
Returns the length measured in number of characters from the given start and end byte offset.
-
#char_offset(byte_offset) ⇒ Object
Returns the character offset for a given byte offset Ruby 19 is multibyte but has no character position methods, must use byteslice.
-
#extract_text(offset, length) ⇒ Object
Extracts the text from byte offset with given byte length.
-
#offset_on_line(offset) ⇒ Object
Returns the offset on line (first offset on a line is 0).
