Poor::Markup

Calls the given block once for each element in self, passing that element as a parameter.

a = ["a", "b", "c"]
a.each { |x| print x, " -- " }

produces:

a -- b -- c --

Returns an Iterator for the elements of self.

a = ["a", "b", "c"]
iter = a.each
iter.next # => "a"
iter.next # => "b"

The returned iterator keeps a reference to self: if the array changes, the returned values of the iterator change as well.

Appends this struct's name and instance variables names and values to the given IO.

struct Point
  def initialize(@x : Int32, @y : Int32)
  end
end

p1 = Point.new 1, 2
p1.to_s    # "Point(@x=1, @y=2)"
p1.inspect # "Point(@x=1, @y=2)"

Pretty prints self into the given printer.

By default appends a text that is the result of invoking #inspect on self. Subclasses should override for custom pretty printing.

Returns the number of elements in this container.

Converts the rich text into text with ANSI escape codes for display in terminal.

Returns the element at the given index, without doing any bounds check.

Indexable makes sure to invoke this method with index in 0...size, so converting negative indices to positive ones is not needed here.

Clients never invoke this method directly. Instead, they access elements with #[](index) and #[]?(index).

This method should only be directly invoked if you are absolutely sure the index is in bounds, to avoid a bounds check for a small boost of performance.

Sets the element at the given index to value, without doing any bounds check.

Indexable::Mutable makes sure to invoke this method with index in 0...size, so converting negative indices to positive ones is not needed here.

Clients never invoke this method directly. Instead, they modify elements with #[]=(index, value).

This method should only be directly invoked if you are absolutely sure the index is in bounds, to avoid a bounds check for a small boost of performance.
