Ruby seems to be passing over a breakpoint in a class initialize
function. "Got grid" is the only break that occurs before the program

breakpoint wasn't found or didn't work?
grid after "Got grid":
=> [[nil, nil, nil], [nil, nil, nil], [nil, nil, nil]]
In file controllers/t3_controller.rb:
...
grid = Grid.new(gridStr)
breakpoint "Got grid"
...
In file controllers/t3/t3lib.rb:
module Cell
class Val < String
def isBlank
self == BLANK
end
end
BLANK = Val.new(' ')
end
class Grid < Array
def initialize(array = ())
super(3) { |row| Array.new(3,Cell::BLANK) }
breakpoint "Grid initialized"
Well I'm not sure what else is in your real code, but I just tried
this, and it works. Not that I'm a big fan of subclassing core classes
either:
rick@frodo:/public/rubyscripts$ cat gridtest.rb
require 'rubygems'
require_gem 'ruby-breakpoint'
module Cell
class Val < String
def isBlank
self == BLANK
end
end
BLANK = Val.new('')
end
class Grid < Array
def initialize(array=())
super(3) {|row| Array.new(3, Cell::BLANK)}
breakpoint "Grid initialized"
end
end
grid = Grid.new("foo")
breakpoint "Got grid #{grid.inspect}"
rick@frodo:/public/rubyscripts$ ruby gridtest.rb
Executing break point "Grid initialized" at gridtest.rb:17 in `initialize'
irb():001:0> quit
Executing break point "Got grid [[\"\", \"\", \"\"], [\"\", \"\",
\"\"], [\"\", \"\", \"\"]]" at gridtest.rb:22
irb(main):001:0> quit

By the way, what's up with the array=() parameter in initialize?
1) You don't seem to be using it,
2) The default value is () which is nil, did you mean []?
