Hello...
irb(main):040:0> width = nil
=> nil
irb(main):041:0> "door#{" and width #{width}" if width}"
=> "door"
irb(main):042:0> width = 99
=> 99
irb(main):043:0> "door#{" and width #{width}" if width}"
=> "door and width 99"
irb(main):044:0> "door#{" and width=#{width}" if width}"
irb(main):045:0*
I'm stuck :-/
- why does the = change something - other chars work?
- how to fix it?
Thanks!
Martin
The problem is partially in irb. Your code works if you put it in a Ruby file
and go from there. However, your code will be easier to understand and even irb
gets it if you switch one of the two quoted strings to use an
alternative quote, e.g.,
irb(main):001:0> width = nil
=> nil
irb(main):002:0> %Q(door#{" and width #{width}" if width})
=> "door"
irb(main):003:0> %Q(door#{" and width=#{width}" if width})
=> "door"
irb(main):004:0> width = 99
=> 99
irb(main):005:0> %Q(door#{" and width #{width}" if width})
=> "door and width 99"
irb(main):006:0> %Q(door#{" and width=#{width}" if width})
=> "door and width=99"

works - thanks!
I still consider irb and .to_yaml the most useful testing tools, tripping on
an irb issue can happen
