File.fnmatch and **

ruby-talk
1

Dir.glob('**/*') matches directories recursively, but File.fnmatch('**/*', "a/b/c", File::FNM_PATHNAME) returns false. I thought (from reading the docs at ruby-doc.org) that the patterns are supposed to be the same.

Can I match directories recursively with File.fnmatch?

Well, File.fnmatch on ruby1.9 works like that.

irb(main):002:0> File.fnmatch('**/*', 'a/b/c', File::FNM_PATHNAME)
=> true
irb(main):003:0> File.fnmatch('a**/*', 'a/b/c', File::FNM_PATHNAME)
=> false
irb(main):004:0> File.fnmatch('**/b*', 'a/b/c', File::FNM_PATHNAME)
=> false
irb(main):005:0> File.fnmatch('**/*', '/a/b/c', File::FNM_PATHNAME)
=> true
irb(main):006:0> File.fnmatch('**/*', 'c:/a/b/c', File::FNM_PATHNAME)
=> true

Does this fit your need?

Yes, well the following returns true as well, which is not desirable. I need to pass the File::FNM_PATHNAME for fnmatch to treat the string as a path and not a file name.

[ts@argon qtruby-1.0.8]$ ruby -v -e 'p File.fnmatch("*", "a/b/c")'
ruby 1.8.2 (2004-12-25) [i686-linux]
true

I just wonder why only Dir.glob understands the ** pattern.

Yes, that's perfect!

(a) fnmatch conforms POSIX standard which does not contain **
    pattern.

(b) besides that, there's no good implementation of fnmatch that
    supports ** pattern when FNM_PATHNAME is specified.
