Shell completions for ddf command

Zsh

We need to enable completion in Zsh if it's not done yet. For example if we are going to put the completion file in ~/.zsh-completions, we should add following lines to ~/.zshrc:

# folder of autocomplete functions
fpath=($HOME/.zsh-completions $fpath)

# enable autocomplete function
autoload -U compinit
compinit

Then create a file ~/.zsh-completions/_ddf, append following lines:

#compdef ddf
_ddf() {
  local -a commands
  commands=(
   'build_recipe:create a complete recipe by expanding all includes in the input recipe.'
   'cleanup:clean up ddf files or translation files.'
   'create_datapackage:create datapackage.json'
   'merge_translation:merge all translation files from crowdin'
   'new:create a new ddf project'
   'run_recipe:generate new ddf dataset with recipe'
   'split_translation:split ddf files for crowdin translation.'
   'validate_recipe:validate the recipe'
  )
  if (( CURRENT == 2 )); then
    _describe -t commands 'commands' commands
  else
    _path_files
  fi

  return 0
}

_ddf

reload the shell and the completion should work.
