dtool-symlink 0.1.0

Create dataset where data directory is a symlink

Add ability to create dataset where data directory is a symlink.

Installing this package provides the dtool command line client with a storage broker named symlink. This is useful if one wants to mark up files in a directory as a dataset without having to re-organise their structure on disk. For example if one wants to mark up some Next Generation Sequencing data that has arrived on an external hard disk as a dataset before copying the resulting dataset to some other form of storage.

If one wants to make use of the dtool_symlink.storagebroker.SymLinkStorageBroker class programatically one needs to create a function that returns the data directory to be symbolically linked. This function is then passed into the SymLinkStorageBroker.create_structure() method. For example:

from dtool_symlink.storagebroker import SymLinkStorageBroker

def get_data_dir():
    return "/my/path/with/data"

symlink_storage_broker = SymLinkStorageBroker("/path/to/dataset")
symlink_storage_broker.create_structure(get_data_dir)
