@return [String] A new string with the amendments applied to it.

@return [Fixnum] The number of lines currently in `eval_string` (the
input buffer)
# File lib/pry/commands/amend_line.rb, line 62 def line_count eval_string.lines.count end
The lines (or line) that will be modified by the `amend-line`. @return [Range, Fixnum] The lines or line.
# File lib/pry/commands/amend_line.rb, line 90 def line_range start_line_number, end_line_number = start_and_end_line_number if start_line_number zero_indexed_range_from_one_indexed_numbers(start_line_number, end_line_number) else line_count - 1 end end

Returns the (one-indexed) start and end lines given by the user. The lines in this range will be affected by the `amend-line`. Returns `nil` if no lines were specified by the user. @return [Array<Fixnum>, nil]
# File lib/pry/commands/amend_line.rb, line 70 def start_and_end_line_number start_line_number, end_line_number = args end_line_number ||= start_line_number.to_i [start_line_number.to_i, end_line_number.to_i] if start_line_number end
Takes two numbers that are 1-indexed, and returns a range (or number) that is 0-indexed. 1-indexed means the first element is indentified by 1 rather than by 0 (as is the case for Ruby arrays). @param [Fixnum] start_line_number One-indexed number. @param [Fixnum] end_line_number One-indexed number. @return [Range] The zero-indexed range.
