previewer: tar.gz (and more) previewer

[krzysztof]

Add previewer for tarball (tar.gz), and perhaps some of the other popular archive formats.

• .tar
• .tar.gz
• .tar.bz2
• .tbz
• .tbz2
• .7z

I like to work on this issue. Can you explain a little more?

[krzysztof]

@shark-s You'll need to take a close look at the ZIP format previewer in the invenio-previewer extensions here: https://github.com/inveniosoftware/invenio-previewer/tree/master/invenio_previewer/extensions and see how it works in Zenodo (and also the whole invenio-previewer module).

Then create something similar to ZIP previewer for another format. I am not sure which of the ones above would be the easiest to start with, but I guess something like .tar or .tar.gz should allow you to look at the header of the archive without unpacking it.

@shark-s .... are you still working on this issue?.. If not, i would like to work on it.

[rajat1994]

@krzysztof .... do we have to create a whole zenodo previewer for this one like invenio previewer?

[krzysztof]

@rajat1994 Yes, it should be a new extension file like this: https://github.com/inveniosoftware/invenio-previewer/blob/master/invenio_previewer/extensions/zip.py

[krzysztof]

It should be a PR to Invenio module. Here's a guide on how to checkout Invenio module locally: http://zenodo.readthedocs.io/en/latest/development/guide.html

So test with Zenodo, but push all the code to invenio-previewer extensions
