Hi,

I am returning to a bit of Ruby hacking = after=20 spending a couple of years away from it. I met someone who is = newer to=20 Ruby and caught some of their excitement for it (Hi Dan).

My day job has me writing Java = code. As many=20 of you will know the default build tool for Java projects is ANT. = ANT is a=20 step forward from the pre-ANT world, but has problems -- one of the big = ones is=20 that it is XML based, and thus verbose. XML as good as YAML for = data, and=20 not as good as Ruby for programming :).

Dan and I were talking about building a = Ruby=20 replacement for ANT. One week-end we both decided to start writing = it, and=20 came up with test-cases.. Dan came up with a name (BOB), and there is = now a=20 piece of vapourware.

My test cases are to do with ANT = FileSetish=20 behavour.

Ant has some interesting globbing = functionality=20 that works very similar to File::fnmatch, but slightly = different.

I like the ant way, but don't want to = suprise Ruby=20 people.

Here is the test cases that talk about = the=20 behaviour I want.

File.fnmatch would provide similar = functionality=20 (with File::FNM_PATHNAME it comes really close), except I don't see that = the=20 last test could past easily.

Before I make the last test pass, I = want to know if=20 Ruby people would find the behaviour described to be = suprising?

        matcher=20 =3D FilePatternMatcher.new
        = assert(matcher.match("test.txt",=20 "test.txt"))
       =20 assert(matcher.match("test.txt",=20 "*"))
       =20 assert(matcher.match("second.txt", "*"))
       =20 assert(matcher.match("test.txt", "*.txt"), "*.txt should match=20 test.txt")
        matcher =3D=20 FilePatternMatcher.new
       =20 assert(matcher.match("test.txt", "test.*"), "test.* should match=20 test.txt")
       =20 assert(!matcher.match("somedirectory/test.txt", "*.txt"), "*.txt = should not=20 match somedirectory/test.txt")
       =20 assert(!matcher.match("test.txt", "*.doc"))
       =20 assert(matcher.match("first/second/test.txt", = "**/test.txt"))
       =20 assert(!matcher.match("first/second/third/fourth/fifth/test.txt",=20 "**/third/*/test.txt"))
