Spreadsheet development

Ahmed Abdelsalam

4/21/2009 10:31:00 PM

Hi,...

I'd like to create a Spreadsheet model, where I can access cells like
the following:

sheet = Spreadsheet.new
sheet.cells.a1 = 'Hello'
sheet.cells.b3 = 'World'

The problem is in how to define cell names to be accessed in the above
manner?

Any help?

Thanks

Ahmed

method_missing should do it

irb(main):001:0> class Cells
irb(main):002:1> def method_missing(meth, *args)
irb(main):003:2> print "you tried to access cell #{meth}"
irb(main):004:2> end
irb(main):005:1> end
irb(main):006:0> cells = Cells.new
irb(main):007:0> cells.a1
you tried to access cell a1

Thanks martin for your response. I've tried it with ruby and it's OK.
Actually my objective is to run it with JRuby, but the same code is
giving error:
at (unknown).(unknown)(Unknown Source)
at #<Class:01x114025>.method_missing(<unknown>:1)
at (unknown).(unknown)(:1)

Any suggestion?

Regards,..

Upgrade? There were problems with method_missing in older versions of
JRuby. I don't know what version you're using, but I would suggest
1.2.

Bart Star would be proud of you, it was his favorite exercise.
