I know that File.fnmatch? returns false for file names starting with a
dot,
unless you specify the File::FNM_DOTMATCH argument. The reason is that
files
starting with a dot are hidden files and so you (usually) don’t want to
take
them into account.
However, I just discovered that it also returns false for file names
starting
in ./ , for example ./xyz.rb. I think this behaviour is wrong: this
isn’t a
hidden file, but a common file in the current directory. This can lead
to
unexpected (in my opinion) results. For example, look at this code:
require ‘find’
Find.find(’.’){|f| puts f if File.fnmatch(’*.rb’, f)}
Since Find.find passes to the block filenames starting with ./ , no
file,
regardless of their extension, will be matched by fnmatch. This is not
what
most people expects. To make the above work, I’d either have to pass the
flag
File::FNM_DOTMATCH to the fnmatch (which would have the unwanted side
effect
of also matching hidden files) or to manually remove the leading dot
from the
file name.
What do others think?
