Each roll-over in File?

ruby-talk
1

fellow, Rubyists:

I have the following code in a PDF writer using Prawn on Ruby 1.8.7 p249
(Default on Ubuntu 10.04). My problem is that the

     @src_file.each do | line |
        ...
     end

... block appears to be rolling over and repeating lines from the beginning
of the file. I tried to use p330 but due to Debian's known ...
eccentricities... it won't load my ruby gems.

                    @src_file = File.open @src_fn
                    Prawn::Document.generate( @out_fn ) do | pdf |
                        @next = true
                        @src_file.each do | line |
                            while @lines_to_do < 1 do
                                update_state_n_format( pdf )
                                @next = true if @lines_to_do <= 0
                            end
                            process_line( line, pdf )
                            @lines_to_do -= 1
                        end
                        @src_file.close
                    end

Is this a known issue? Or already fixed?

                   @src\_file\.each do | line |
                       while @lines\_to\_do &lt; 1 do
                           update\_state\_n\_format\( pdf \)
                           @next = true if @lines\_to\_do &lt;= 0
                       end
                       process\_line\( line, pdf \)
                       @lines\_to\_do \-= 1
                   end

Are you positive that nothing in update_state_n_format() or
process_line() is touching @src_file and perhaps rewinding the file's
read position?

Wondering,
Aaron out.

I did figure it out. Above this code is a line that says

   close if @done == true

... the close being a wxRuby close(), and it was actually coming back from
the close() and re-opening the file and crashing before the close()
completed all its operations at the Wx level.

Changing it to

   if @done == true then
      close
   else
      # parse the file
   end

...worked.

In other words, close() != die() :smiley:
