Re: [Tracker] Extending indexed file types

[Björn Johansson <bjorn_johansson bio uminho pt>]

Hi, I get 

bjorn@bjorn-ThinkPad-T450s:~/Desktop$ gio info jupyter_note_book.ipynb |grep content-type

  standard::content-type: application/x-ipynb+json

  standard::fast-content-type: application/x-ipynb+json

bjorn@bjorn-ThinkPad-T450s:~/Desktop$ tracker daemon

Ill try to understand how the extractors work. Thanks for the help.

Yes, Tracker has no specific knowledge of these files.

We do accept patches :). As Debarshi pointed out, there's quite a few
examples in src/tracker-extract in the tracker git tree.

But those Tracker extract modules rely on specific enough mimetypes,
could be worth checking first whether shared-mime-info knows about
jupyter specifically, eg. doing:

gio info $FILE |grep content-type
