Dir.glob and File.fnmatch

[Thomas Leitner]

Hi,

I always thought that the arguments to Dir.glob(...) and
File.fnmatch(...) are the same. However, with the first I can use
braces, with File.fnmatch not!

irb(main):001:0> Dir['*']
=> ["src", "plugin"]
irb(main):002:0> Dir.glob('s{rc}')
=> ["src"]
irb(main):003:0> File.fnmatch('s{rc}','src')
=> false

Is it somehow possible to use braces with File.fnmatch(...)?

Brace Expansion is different from Pathname Expansion.

Yes, PickaxeII contains a better explanation than ri and effectively
differentiate the semantics between the two: "Because fnmatch is
implemented by the underlying operating system, it may have different
semantics to Dir.glob." ==> ie: braces are not used to delimit patterns
to match.

IMHO ri description needs to be slightly enhanced.

Thanks for the answers! So I will stick to Dir.glob for the time being.
