examples:

$ digikuery tag Paquerette

Install

$ pip install digikuery

Example: Query which albums contain given tag expression

Bellow we look for the "semaphore" name in all tags.

The query returns 2 tags "TagCommunication/Semaphore/Bleu" and "TagAlphabet/Semaphore", listing for each tag the albums containing tagged pictures.

$ digikuery tag semaphore
  3 TagCommunication/Semaphore/Bleu
      album_albanie
      album_france
      album_grece
  1 TagAlphabet/Semaphore
      album_photos_19e_siecle

Providing -I option would list the picture names.

Let's just sort them by picture count:

$ digikuery tag -C semaphore
  3 TagCommunication/Semaphore/Bleu
      3 album_france
      2 album_grece
      2 album_albanie
  1 TagAlphabet/Semaphore
      19 album_photos_19e_siecle

For each matching album we can show if it contains other tags, for example tags maching "access"

$ digikuery -T access tag semaphore
  3 TagCommunication/Semaphore/Bleu
      album_france
        TagAccess/Walking (9), TagAccess/Train(1)
      album_grece
		TagAccess/Car(6), TagAccess/Walking (3)
      album_albanie
		TagAccess/Walking (5)
