string	moose::moosePathToUserPath (string path)
	When user gives a path /a/b/c, moose creates a path /a[0]/b[0]/c[0]. This is helpful in cases where one needs to create more than 1 element. More...

Here is the caller graph for this function:

string joinPath	(	string	pathA,
		string	pathB
	)

Append pathB to pathA and return the result.

If pathA does not have [indexs] at the end, append "[0]" to pathA and then add pathB to it. This version does not care if the result has '[0]' at its end.

Parameters

pathA	First path.
pathB	Second path.

Returns

A string representing moose-path.
