• treeload directory file
  • Loads a file into a tree rooted at directory according to rules described later.
• treedump directory file
  • Dumps a tree rooted at directory into a file in one of the supported formats.

Currently libucl is used to read and write files so that UCL or JSON files can be loaded with treeload; and JSON (pretty, compact), YAML (compact), and msgpack, can be dumped with treedump.

• Tree leaves, that is non-object, non-array object members or array elements become regular files with their key as the file name and value as file content. Key of array elements is their implicit zero-based index.
• Objects and arrays become directories named after their key. They contain files and directories corresponding to child leaves or other objects and arrays.

Let's consider a simple example with a structure in UCL format:

people = [
	{name = "Alice", genius = yes, items = [phaser]}
	{name = "Bob", genius = no, items = [cap, stick]},
]

The resulting file tree produced by treeload is as follows:

people/
	0/
		name    -> Joe
		genius 	-> no
		items/
			0     -> cap
			1     -> stick
	1/
		name    -> Alice
		genius  -> yes
		items/
			0     -> phaser

• Write treedump.
• Write actual tree-making code instead of emitting a shell script.
• Rewrite as a Lua host (script?) driven by Lua tables.
  • This way any structured format can be generically plugged in by writing a binding and using it to fill a Lua table.
