Represents a line of code. A line of code is a tuple, which consists of a line and a line number. A `LOC` object's state (namely, the line parameter) can be changed via instance methods. `Pry::Code` heavily uses this class.
@api private @example
loc = LOC.new("def example\n :example\nend", 1) puts loc.line def example :example end #=> nil loc.indent(3) loc.line #=> " def example\n :example\nend"
@return [Array<String, Integer>]
@param [String] line The line of code. @param [Integer] lineno The position
of the line
.
# File lib/pry/code/loc.rb, line 27 def initialize(line, lineno) @tuple = [line.chomp, lineno.to_i] end
@return [Boolean]
# File lib/pry/code/loc.rb, line 32 def ==(other) other.tuple == tuple end
Prepends the line number `lineno` to the `line`.
@param [Integer] max_width @return [void]
# File lib/pry/code/loc.rb, line 62 def add_line_number(max_width = 0) padded = lineno.to_s.rjust(max_width) colorized_lineno = Pry::Helpers::BaseHelpers.colorize_code(padded) tuple[0] = "#{ colorized_lineno }: #{ line }" end
Prepends a marker "=>" or an empty marker to the line
.
@param [Integer] marker_lineno If it is equal to the `lineno`, then
prepend a hashrocket. Otherwise, an empty marker.
@return [void]
# File lib/pry/code/loc.rb, line 73 def add_marker(marker_lineno) tuple[0] = if lineno == marker_lineno " => #{ line }" else " #{ line }" end end
Paints the `line` of code.
@param [Symbol] code_type @return [void]
# File lib/pry/code/loc.rb, line 54 def colorize(code_type) tuple[0] = CodeRay.scan(line, code_type).term end
# File lib/pry/code/loc.rb, line 36 def dup self.class.new(line, lineno) end
Indents the `line` with distance
spaces.
@param [Integer] distance @return [void]
# File lib/pry/code/loc.rb, line 86 def indent(distance) tuple[0] = "#{ ' ' * distance }#{ line }" end
@return [String]
# File lib/pry/code/loc.rb, line 41 def line tuple.first end
@return [Integer]
# File lib/pry/code/loc.rb, line 46 def lineno tuple.last end
