File.yaml? provides a way to check if a file is a YAML formatted file:

File.yaml?('project.yaml')  #=> true
File.yaml?('project.xml')   #=> false

Note this isn't perfect. At present it depends on the use use of an initial document separator (eg. '---'). With YAML 1.1 the %YAML delaration is supposed to be manditory, so in the future this can be adapted to fit that standard.

# File lib/facets/standard/facets/yaml.rb, line 39
def self.yaml?(file)
  File.open(file) do |f|
    until f.eof?
      line = f.gets
      break true if line =~ /^---/
      break false unless line =~ /^(\s*#.*?|\s*)$/
    end
  end
end
