I have an of strings which are file names files, and an array of allowed file types or suffixes allowed_types. I want to filter out files which don't end with an allowed suffix.
This does the trick, but I'm wondering if anyone can suggest a neater solution? Such as a way keep with ruby's usual streamlined style without using flag variables.
valid_files = Dir.entries(path).select do |f|
valid = false
allowed_types.each { |suffix| next valid = true if f.end_with? suffix }
next valid
end
