Usage

This is a new library and it needs work! Please don't hesitate to send a pull request or to open an issue if you find something wrong or broken.

datpy.Dat(home='')

Dat is a class that binds to some global Dat. You can provide an optional home variable to pass to the dat cli to store your data somewhere besides your local machine. By default, the metadata storage is placed in ~/.dat.

> import datpy
> mydat = datpy.Dat()

For each command, a dat instance accepts any of the options supported by Dat's commandline api.

mydat.share(path)

Creates a fingerprinted dat link to the data. This is a unique link that can be given to download. This will open a TCP connection to the public network to share the data.

Example:

> mydat.share('./path/to/my/data')
'a53d819bdf5c3496a2855df83daaac885686cac4b0bccfc580741b04898e3b32'

mydat.download(link, path)

Downloads the link to the local hard drive. This will open a TCP connection to the public network to connect to the swarm assocaited to this link. It will download the data and will remain open to re-host it for redundancy. You can provide an optional path argument to download the data to a specific folder.

> dat.download('a53d819bdf5c3496a2855df83daaac885686cac4b0bccfc580741b04898e3b32', 'data')

mydat.close()

Closes any connections opened with download or link.

Development

We recommend using virtualenv to develop datpy. Set up your environment like this:

$ virtualenv env

And then every time you want to start developing, do this:

$ source env/bin/activate
$ python setup.py develop

Contributing

$ git clone http://github.com/<your-fork>/datpy
$ pip install -r requirements.txt
$ git commit -am "BUG: there was a bug here fixes #33"
$ git push origin master
 ... open pull request!
