rubymine - run a ruby project on ruby mine -
i new ruby programming. wrote little program recursively count blobs in 2 dimensional array. contains 2 classes, cell , blobs. getting following error , dont know means or how fix it.
attached code , error. cell class
class cell attr_accessor :data,:visited,:row,:col def initialize(data, row, col) @data = data @visited = false @row = row @col = col end def to_s self.data.to_s end end blob class
class blobs require ./cell @cells = array.new(10){array.new(10)} def separate(percentage) in 0..10 in 0..10 random = random.rand(0,100) if random < percentage @cells[i][j] = cell.new('x',i,j) else @cells[i][j] = cell.new(nil, i, j) end end end end def markblob(currentcell) if currentcell.visited return end currentcell.visited = true if currentcell.data.nil? return end if currentcell.row >0 markblob(@cells[currentcell.row-1][currentcell.col]) end if currentcell.row <@cells.size-1 markblob(@cells[currentcell.row+1][currentcell.col]) end if currentcell.col>0 markblob(@cells[currentcell.row][currentcell.col-1]) end if currentcell.col<@cells.size-1 markblob(@cells[currentcell.row][currentcell.col+1]) end end def countblobs count = 0 in 0..10 j in 0..10 cell = @cells[i][j] if !cell.visited && cell.data.nil? count++ markblob(cell) end end end return count end def to_s in 0..10 j in 0..10 if @cells[i][j].data.nil? puts '- ' else puts @cells[i][j].data + ' ' end end puts "\n" end end blob = blobs.new number = blob puts number end this error getting:

require should string argument.
use require_relative cell file
require_relative 'cell' and put above class blobs.
