Dynamic Arrary Names

[M. Muzaffar]

Is there any way in ruby to create dynamic array names?

correctarrayfiles=Dir.glob("array_ast_correct_*.rb").size
correctarrayfiles.times do |num|
correctfiles=findbug.file_exist("array_ast_correct")
array+num=findbug.mark_arrary(correctfiles[num])
end

There would be then a new arrays like

arrary0
arrary1
....
....

Hi --

Is there any way in ruby to create dynamic array names?

correctarrayfiles=Dir.glob("array_ast_correct_*.rb").size
correctarrayfiles.times do |num|
correctfiles=findbug.file_exist("array_ast_correct")
array+num=findbug.mark_arrary(correctfiles[num])
end

There would be then a new arrays like

arrary0
arrary1

Try Googling as follows:

create dynamic variables ruby

As you'll see, it's impossible (or nearly so) and ill-advised.

You are overcomplicating.

correctarrayfiles = Dir.glob("array_ast_correct_*.rb").size
corrected_files = (0...correctarrayfiles).map do |num|
correctfiles = findbug.file_exist("array_ast_correct")
findbug.mark_arrary(correctfiles[num])
end

Now corrected_files contains an array of whatever findbug.mark_arrary
returns. This is semantically identical to your original code, though I
think there are probably issues with the original code, including typos.
