I’ve got a problem with displaying files of a same extension

The source code:

Please be simple as you can while explaining, I’m not an English men.

Hello,

didn’t run the code but when using interpolation you have to use “”
(double quotes) and not ‘’ (single quotes) like:

Dir.glob [".#{ext}"] instead of Dir.glob ['.#{ext}']

You can also use Dir[] instead of Dir.glob()

And you can build your variable before passing it to Dir[] such as via

x = ‘foo/’
x << ‘*’
Dir[x]

The variant #{x} is really only useful in a String.
Dir["#{x}"] is unnecessary.

Oh my god, thank you very much.

I tried all possible combination but how could i not think of that. Once
again, thanks.

There are two issues

  • You are trying to use string interpolation with single quotes (you
    need double quotes).
  • You are mixing two approaches with the square brackets and Dir#glob

irb(main):005:0> ext = “sh”
=> “sh”
irb(main):006:0> Dir[“.#{ext}“]
=> [“args.sh”, “backup-rsync.sh”, “java-exec.sh”, “jobs.sh”, “loc.sh”,
“mwg-saas-props.sh”]
irb(main):007:0> Dir.glob(”.#{ext}”)
=> [“args.sh”, “backup-rsync.sh”, “java-exec.sh”, “jobs.sh”, “loc.sh”,
“mwg-saas-props.sh”]
