Tips & Tricks¶
Browsing the database¶
A portable way to browse the underlying sqlite database is to use the super secret
/.supertag directory that lives
in your collection’s mountpoint. Inside, there is a
db.sqlite3 file that you can connect to. See Database Schema
for a detailed listing of each table.
Sometimes it is useful to list all intersections sans a tag. For example, if you wanted to
list all files that are
trips, that are not tagged with
seattle, how would you do it? The answer
is tag negations:
Simply prepend the
- character before any tags that you wish to negate from the intersection, and Supertag will
do the right thing.
Tag Group Transparency¶
A tag group has “stat transparency” to the tags it contains. What this means is although you cannot always see the tags contained by a tag group, you can pretend that they are there. An example will make this more clear. Suppose you have the following file structure::
/ 2016/ ... photos/ ... people/ person-1/ person-2/ person-3/
people is a tag group for the tags
person-3. This means that wherever
one of those tags would appear, the tag group will appear instead. So for example, if there exists an
photos will show::
photos/ people/ person-1/
people is shown as the immediate child of
person-1 would have been listed, but
has a tag group, so the tag group was shown instead.
However, “stat transparency” means that although
person-1 isn’t the immediate child of
photos, we can treat it
as if it was. This means that you can do
ls people/person-1/⋂ to list the intersection of those two tags, without
needing to go through the
people tag group.
