This makes no sense to me, so...I could use a little help
In my main program I read in some ruby from an external file:
eval( File.read( "../lib/setnet/Utilities.rb" ) )
I check a variable which should now be defined (by a line in that file),
using ruby-debug:
Breakpoint 1 at SN.rb:550
../lib/setnet/SN.rb:550
pp menu_ut # <= my main program code about to execute, so menu_ut
better be there
(rdb:1) p defined? menu_ut
"local-variable" # <= looks good
(rdb:1) p menu_ut # <= this successfully prints the expected contents
of this array.
[...]
(rdb:1) c # now the above line of program code should execute without
error...and we get instead...
../lib/setnet/SN.rb:550:in `proc_command': undefined local variable or
method `menu_ut' for #<SN::SetNet:0xb79adac8> (NameError)
...and it blows.
How can this be?
I do know that if I make this variable a constant, in the input file,
all is well. But I had thought an ordinary variable would be fine, as
the input code is evaluated in the current binding...only it doesn't
seem to be there (the variable), unless you ask ruby-debug, which says
it is.
I cannot make sense of this. And...I need to fix it somehow.
All suggestions most welcome.
