Chef in bash

UPDATE: I am actually seriously using this idea, implemented in a project named poop: https://github.com/destructuring/poop (as in, people will poo-poo this idea, or in the end, it's all crap anyways).

Pretend I want these chef-like resources to execute in bash without ruby.

directory "$HOME/dir"
 owner "$USER"
 group "staff"
 mode 0755
end

link "dir"
 to "$HOME/slink"
end

Interesting, no? Wonder how far I could take this. Maybe check back to this protip and I'll have a git repo up =)

First, define the resource functions, directory and link.

function directory {
 resource="directory"
 name="1ドル"; shift
}

function link {
 resource="link"
 name="1ドル"; shift
}

Then define the attributes.

function owner {
 _owner="1ドル"; shift
}

function group {
 _group="1ドル"; shift
}

function mode {
 _mode="1ドル"; shift
}

function to {
 _to="1ドル"; shift
}

The end function does all of the work.

function end {
 case "$resource" in
 directory)
 mkdir -p "$name"
 [[ -n "$_owner" ]] && chown "$_owner" "$name"
 [[ -n "$_group" ]] && chgrp "$_group" "$name"
 [[ -n "$_mode" ]] && chmod "$_mode" "$name"
 ;;
 link)
 ln -nfs "$name" "$_to"
 [[ -n "$_mode" ]] && chmod "$_mode" "$_to"
 ;;
 esac

 unset _name _owner _group _mode _to
}

#bash

#chef
