Feature #8269: stdlib: Add Find.each_file to accompany Find.find

Often when I use the find module, I am only interested in files.
Since Find.find returns files and directories, I often write code
that looks like this:

Find.find('foo/bar') do |f|
next if File.directory? f

code code code ...
end

To remove the test for directories, a class method, called find.each_file
could be added, which would only yield files.

module Find
def self.each_file(*paths)
block_given? or return enum_for(method, *paths)
self.find(*paths) {|f yield f unless File.directory? f}
end
end

• File 8269_Find_each_file.patch 8269_Find_each_file.patch added

Is there a use-case for each_directory as well?

(Attached patch is only for each_file method, and includes basic tests)

I think this is out of the scope of find.rb, see "find.rb: the Find module for processing all files under a given directory."

If you want this feature, I think you should write a gem.
