Goling

Goling is a linguistic compiler allowing you to compile and execute plain english. And thus allows you to program in plain english provided you have the reduction rules needed.

Since the code ends up compiled like all code should be you can execute your code so amazingly fast I am in awe just to be able to write this divine text to you about it.

Installation

gem install goling

Basic usage

reduce /all directories/ => 'directories' do
  Dir.entries('.').select{ |f| f[0] != '.' && File.directory?(f) }
end

reduce /({directories:[^}]*}) recursively/ => 'directories' do |dirs|
  all_dirs = dirs
  Find.find(dirs) do |path|
    if FileTest.directory?(path)
      if File.basename(path)[0] == '.'
        Find.prune       # Don't look any further into this directory.
      else
        all_dirs << path
        next
      end
    end
  end
  all_dirs
end

reduce /all files inside ({directories:[^}]*})/ => 'files' do |dirs|
  dirs.map{ |f| File.new(f, "r") }
end

reduce /view ({files:[^}]*})/ => '' do |files|
  files.each do |file|
    pp file
  end
end

"view all files inside all directories recursively".linguify.to_ruby
# => code = lambda do
#      directories_0 = Dir.entries(".").select { |f| ((not (f[0] == ".")) and File.directory?(f)) }
#      directories_1 = (all_dirs = dirs
#      Find.find(dirs) do |path|
#        if FileTest.directory?(path) then
#          if (File.basename(path)[0] == ".") then
#            Find.prune
#          else
#            (all_dirs << path)
#            next
#          end
#        end
#      end
#      all_dirs)
#      files_2 = dirs.map { |f| File.new(f, "r") }
#      files.each { |file| pp(file) }
#    end
#    Goling::Linguified.trampoline(code)

And if you simply want to execute your magnificent piece of art:

"view all files inside all directories recursively".linguify.run

Or even:

# compile once, run plenty
code = "view all files inside all directories recursively".linguify
loop do
  code.run
end
