Might as well post my little script here for searching files in a directory that contains _all_ the given words, no matter what line they’re on. So it’s awesome for writing your own package and searching examples in nixpkgs like “where did someone use `makeWrapperArgs` and `PATH`”.

```ruby
#!/usr/bin/env ruby

Dir.glob('**/*') do |path|
  next unless File.file?(path)
  File.open(path, 'r:binary'){|io|
    ARGV.all?{|word|
      io.rewind
      io.grep(/#{word}/).any?
    } && puts(path)
  }
end

```

Usage like `find-all-with-words setupPyBuildFlags buildPython`.
