Overview

<progress> — value and max (default max=1). position returns value / max for a "determinate" progress bar, or -1 when no value is set ("indeterminate").

def max
  raw = @__node__["max"].to_s
  m = raw.empty? ? 1.0 : (Float(raw) rescue 1.0)
  # A `max` not greater than zero is invalid; the default (1) applies.
  m > 0 ? m : 1.0
end

#max=(v) ⇒ Object

The max IDL attribute is limited to numbers greater than zero: a setter value that isn't is ignored (the content attribute is left unchanged).

def max=(v)
  f = Float(v) rescue nil
  set_reflected_string("max", v.to_s) if f && f > 0
end

#position ⇒ Object

position = value/max for a determinate bar; -1 for an indeterminate one (no parseable value content attribute).

def position
  return -1.0 unless determinate?

  value / max
end

#value ⇒ Object

A progress bar is "determinate" iff it has a parseable value content attribute; otherwise it is "indeterminate" (position -1). The value IDL getter always returns a number: 0 when indeterminate/invalid, else the value clamped to [0, max].
