How to copy or rename a unique instance

Asked by therapon sundoulos on 2019-02-25

I have several unique instances and find them very useful. Is it possible to copy a unique instance to a different name or rename an existing one? If so, how would I do it?

A little SQL magic once I found the database and I got what I needed.

A Session Manager like Konqueror has would be a nice additional feature.

Hello therapon,

glad that you could help yourself. Just if anyone stumbles upon this in the future: An unique instance is currently nothing but a distinct value in the column "instanceName" of the "tabs_v5" database table that is part of qpdfview's database usually located at "~/.local/share/qpdfview/qpdfview/database". (The table is used to (re)store the opened tabs of any given qpdfview session, i.e. a unique instance is just a set of open tabs.)

So the query the instance, use for example "SELECT DISTINCT instanceName FROM tabs_v5;" whereas "UPDATE tabs_v5 SET instanceName='foo' WHERE instanceName='bar'" would rename instance "bar" into "foo".

Best regards,

(Forgot, the database is an SQLite3 database, so one can for example access it using the sqlite3 command line utility or the sqlitebrowser GUI.)
