does anyone know of a way to do

if filename.glob_match ‘*.txt’
…stuff
end

in ruby?

Dir#/#glob are the closest thing to this functionality - but work only if
the file were to actually exist.

Try fnmatch (in 1.8)

Try fnmatch (in 1.8)

so i should stop work on my fnmatch extension then? :wink:

There’s shim/ruby16/ext/features/ruby18/file.

took me a moment to determine you had to

ruby -r features/ruby18 -e “puts File::fnmatch ‘*.txt’, ‘foo.txt’”
^^^^^^^^^^^^^^^^^^

that could be in the ‘Description:’ on the raa…

but i got it now - thanks!
