Method: Kramdown::Utils::StringScanner#current_line_number

Defined in:
lib/kramdown/utils/string_scanner.rb

#current_line_number ⇒ Object

Returns the line number for current charpos.

NOTE: Requires that all line endings are normalized to ‘n’

NOTE: Normally we’d have to add one to the count of newlines to get the correct line number. However we add the one indirectly by using a one-based start_line_number.
